Boston Red Sox first baseman Triston Casas (knee) has been diagnosed with a ruptured left patellar tendon. Casas was placed on the 10-day injured list earlier on Saturday but is expected to miss the remainder of the 2025 season. He was removed from Friday's contest and had to be taken off the field on a stretcher. For the time being, fantasy managers should expect Romy Gonzalez to see most of the opportunities at first base with Rafael Devers and Connor Wong also being in the mix. Casas had a slow start to the season, holding a .182/.277/.303 slash line with three doubles and three home runs across 29 games. Casas' injury could also eventually open a path for top prospects Roman Anthony or Marcelo Mayer to join the MLB roster as well.

Updating a previous report, Boston Red Sox manager Alex Cora said that first baseman Triston Casas (knee) suffered a significant knee injury in Friday's series opener against the visiting Minnesota Twins at Fenway Park and is currently at the hospital. The skipper said the team will know more on Saturday, but it's a safe bet that Casas will be out for a while. It's not a surprise after the 25-year-old crumbled to the ground after landing awkwardly on first base while running out a groundout. Based on the way the injury looked, a torn ligament in his knee is a possibility, but we'll have a better idea of how long Casas might be sidelined on Saturday. With Casas likely out for an extended period of time, Romy Gonzalez, who replaced Casas at first on Friday, is in line to see regular playing time for the BoSox. In addition to this serious injury, Casas came into Friday's action hitting just .184/.279/.306 with three homers and 11 RBI.

Boston Red Sox first baseman Triston Casas (knee) was removed early during Friday's game against the Detroit Tigers. Casas appeared to have suffered a knee while trying to make it to first base. This looked like an ugly injury and Casas couldn't even get off the field under his own power. The expectation is that the Red Sox will have Casas undergo further testing. However, fantasy managers should prepare for Casas to miss time because of this injury. Romy Gonzalez took over at first base and might see more time over there if Casas heads to the injured list.

Boston Red Sox first baseman Triston Casas (knee) was removed early during Friday's game against the Detroit Tigers and was placed on a stretcher after a scary-looking injury. Casas appeared to have suffered a knee injury while trying to make it to first base. This looked like an ugly injury, and Casas couldn't even get off the field under his own power. The expectation is that the Red Sox will have Casas undergo further testing. However, fantasy managers should prepare for Casas to miss significant time because of this injury. Romy Gonzalez took over at first base and might see more time over there if Casas heads to the injured list, which seems likely based on how the injury looked on Friday night.

After slumping to open the 2025 regular season, Boston Red Sox first baseman Triston Casas worked with hitting coach Pete Fatse this week to move the positioning of his hands further away from his body. The early results have been encouraging after Casas hit a three-run home run for the second straight day in Wednesday's loss to the Seattle Mariners. In his first 23 games, the 25-year-old left-handed slugger had a 39 wRC+ while batting .171 with a .570 OPS, which was the worst month of his career. As a result, manager Alex Cora recently moved him down from his customary fourth spot in the batting order. Both of his homers the last two days were just over 105 mph off the bat, and fantasy managers will be hoping Casas' adjustment with his stance will continue to mean more production after a slow start. Now he just needs to be moved back up the batting order.

Boston Red Sox first baseman Triston Casas blasted a three-run home run and drew one walk in Wednesday's 8-5 loss to the Mariners. This was his second game in a row with a home run, and the slugger is finally showing signs of life after a very slow start to the season. He's batting just .171 on the year with three home runs, 10 RBI, and five runs through 23 games. Even his usually stellar walk rate is down to a middling 8.8%, with truly nothing going right for him over the first few weeks. He seems to be snapping out of it recently though, dating back to Saturday when he delivered a walk-off hit. It's too early to give up on Casas in fantasy, as he still possesses massive power upside.

Boston Red Sox first baseman Triston Casas went 1-for-4 with a home run and three RBI in his team's 8-3 win against the Seattle Mariners. The 25-year-old blasted his second dinger of the season off Mariners reliever Trent Thornton in the bottom of the seventh to give Boston a four-run lead, and they never looked back. It's been a slow few weeks for Casas, as he's gone 6-for-40 (.150) over his last 11 appearances with one extra-base hit, four RBI, and one run scored. The former first-round pick has been superb against left-handed pitchers this season (5-for-8), but struggled against righties to an abysmal .113 batting average. On the bright side, he's cut his strikeout rate by seven points from 2024. Still, it sits at an undesirable 24.1%.

Boston Red Sox first baseman Triston Casas and outfielder Wilyer Abreu will take a seat on Tuesday against the division-rival Toronto Blue Jays and left-hander Easton Lucas at Fenway Park. Romy Gonzalez will make the start at first base and bat seventh, while Rob Refsnyder is starting in right field and is batting cleanup for the BoSox. Casas has gotten off to a slow start this year, going 7-for-39 (.179) with a homer, two doubles, three RBI and 13 K's in 11 games played. Abreu has been excellent, slashing .424/.537/.788 with a 1.324 OPS, three homers, 12 RBI, 10 runs scored and a steal in 33 at-bats. Refsnyder, although he's never faced Lucas in his career, has been known as a lefty killer and will be the more attractive DFS sleeper for Tuesday's slate. In his career, the South Korean outfielder has hit .278 with 15 of his 24 home runs against lefties.

Boston Red Sox first baseman Triston Casas (hand) is starting at first base and batting cleanup on Opening Day. Casas suffered a minor hand injury after fielding a ground ball earlier this week. The X-rays came back negative and did not inhibit him from playing on Opening Day. This is an excellent sign for the 25-year-old as he battled injuries last season, which limited him to just 63 contests. Across this limited stint, Casas posted an underwhelming .241/.337/.462 slash line with eight doubles and 13 long balls. He generated a strong 13.3 percent barrel rate and drew walks at a 12.3 percent rate. In 2023, Casas enjoyed a breakout campaign as he posted a .263/.367/.490 slash line with 24 round-trippers. Fantasy managers should view Casas as a solid No. 1 first baseman in all formats. He is also strong play in DFS this afternoon, facing Texas right-hander Nathan Eovaldi.

Boston Red Sox first baseman Triston Casas (hand) is out of the starting lineup on Tuesday against the Sultanes de Monterrey for an exhibition contest after he tried to barehand a bad-hop ground ball with his right hand on Monday night, according to MLB.com's Ian Browne. X-rays on Casas' hand came back negative, so he avoided a serious injury, and it seems likely that he'll be able to play on Opening Day on Thursday against the Texas Rangers. Fantasy managers are still waiting for a potential breakout for the 25-year-old former first-rounder after he was forced to miss almost four months in 2024 due to torn cartilage in his left rib cage. He wasn't the same hitter when he returned and finished with a .241/.337/.462 slash line with an .800 OPS, 13 homers and 32 RBI in just 63 games. The jury is still out, but Casas is still a low-end starting first baseman in fantasy for his power upside.

Boston Red Sox first baseman Triston Casas (illness) is returning to the starting lineup on Tuesday to face the Philadelphia Phillies. He will cover first base and bat in the three-hole. The 25-year-old has missed time due to an illness. Fantasy managers should continue to monitor his status but it appears he will not be in any danger of missing Opening Day. Last season, Casas made just 63 starts as he sustained a rib injury. Across this stint, he held an underwhelming .241/.337/.462 line with 13 home runs. He drew walks at a strong 13.2 percent rate but struck out at a high 31.7 percent rate. In 2023, Casas enjoyed a breakout campaign as he posted a .263/.367/.490 line with 21 doubles and 24 long balls. Fantasy managers should expect Casas to have an everyday role in the Boston lineup, spending most of his time at first base.

Boston Red Sox first baseman Triston Casas (illness) returned to camp on Sunday. The 25-year-old was dealing with an illness. Fantasy managers should continue to monitor his status but he should have plenty of time to increase his workload by Opening Day. Last season, the 25-year-old only appeared in 63 contests as he missed most of the season due to a rib injury. During this stint, he held a disappointing .241/.337/.462 slash line with eight doubles and 13 long balls. He showed a strong eye at the plate as he drew walks at a 12.3 percent rate and generated an elite 13.3 percent barrel rate. During the 2023 campaign, Casas logged a career-high 132 contests and posted a .263/.347/.490 line with 21 doubles and 24 long balls. When healthy, he should be the everyday first baseman in Boston.

Boston Red Sox first baseman Triston Casas (illness) was scratched from Tuesday's Grapefruit League game against the Pittsburgh Pirates due to a stomach bug that continues to make its way through the team this spring. Casas is under the weather now, but we'd expect him to be feeling good enough to return to spring training action later this week. With the 25-year-old left-handed slugger out on Tuesday, Nathan Hickey will fill in for him at first base and bat cleanup for the BoSox. Casas missed almost four months in 2024 due to torn rib cartilage and had a strikeout rate of 33.3 percent once he returned. The former 26th overall pick in 2018 hit 24 home runs and drove in 165 in his first full MLB season in 132 games in 2023, but his rib injury set him back a year ago. There's no denying that Casas has 30-homer power at first base, but we're still waiting for him to prove it. He's ranked as RotoBaller's No. 12 first baseman.

Despite Boston Red Sox chief baseball officer Craig Breslow denying that the team was shopping first baseman Triston Casas in trades, there remains a belief in the industry that the Red Sox remain open to trading Casas, potentially for young pitching, according to Mass Live's Chris Cotillo. Among other clubs, Boston has discussed Casas with the Seattle Mariners, who continue to look for more bats. The BoSox have been mentioned as a trade possibility for St. Louis Cardinals third baseman Nolan Arenado, which would likely shift incumbent third baseman Rafael Devers from third to first. After adding pitchers Garrett Crochet and Walker Buehler this offseason, their primary focus is now on adding a right-handed bat. The 24-year-old left-handed hitting Casas has immense power, but he missed almost four months in 2024 with torn cartilage in his ribs and had a strikeout rate over 30% when he returned. Despite the risks, the potential remains that he can be a four-category fantasy contributor.

Despite having talked about him in different trade packages this offseason, Boston Red Sox chief baseball officer Craig Breslow said on Monday that the team is "not shopping" first baseman Triston Casas. The situation this offseason with Casas probably depends on whether Boston signs or trades for a third baseman such as Alex Bregman or Nolan Arenado, which would in turn move current third baseman Rafael Devers across the diamond to first base. The 24-year-old Casas has some of the best raw power in the game at the first-base position, but the BoSox are looking to add a right-handed bat, which could make him expendable. Casas' 2024 campaign was marred by a left rib-cage injury that kept him out almost four months, and he had a strikeout rate over 30% when he returned. A true breakout could still be coming, but it might have to come elsewhere.

Boston Red Sox first baseman Triston Casas smashed a trio of homers in Game 1 of the team's doubleheader against the Minnesota Twins on Sunday. Casas finished the game 3-for-4 with seven RBI, accounting for all but one of the team's runs. The 24-year-old could use a strong finish to the season as he has struggled since returning from injury in mid-August, hitting .230 with just four homers in 104 at-bats heading into Sunday's games. He has shown big upside and is still only 24, so there is a good chance that next year will be his coming-out party. He will likely be a popular breakout pick in fantasy drafts.

Boston Red Sox first baseman Triston Casas is sitting out on Thursday in the Bronx at Yankee Stadium against the division-rival New York Yankees with left-hander Nestor Cortes making the start. Connor Wong will make the start at first base and hit sixth, with Danny Jansen behind the plate and batting eighth. Wong is hitting .333 with an RBI against Cortes in nine career at-bats, while Jansen hasn't found similar success with a .143 average in just seven career at-bats. Casas missed the majority of the 2024 regular season due to a rib-cage injury. Since returning from the injured list on Aug. 16, he's hit .247 (20-for-81) with only two home runs, three doubles, 10 RBI, nine walks and 33 strikeouts. The 24-year-old lefty slugger has hit .222 (10-for-45) with only two of his eight home runs on the season against left-handers.

The Boston Red Sox activated first baseman Triston Casas (rib cage) from the 60-day injured list on Friday and designated first baseman/outfielder Dominic Smith for assignment in a corresponding move. Casas is at first base and is batting third in his return from the IL on Friday against the division-rival Baltimore Orioles and right-hander Corbin Burnes at Camden Yards. It's a tough first matchup back for the 24-year-old, who has been out since late April after he tore cartilage in his rib cage. The young left-handed slugger needs to be rostered in all fantasy formats, though, as Boston's best power hitter when healthy. The former 26th overall pick in 2018 hit 24 homers and drove in 65 runs in 132 games in his first full big-league season in 2023 and could make an impact with his power down the stretch in all fantasy formats.

Boston Red Sox first baseman Triston Casas (ribs) is set to return to the lineup on Friday evening, according to Chris Cotillo. Casas has been sidelined since late April with a fracture in his left rib cage. The 24-year-old has had a lengthy recovery process but is now poised to return just in time for the stretch run. Prior to the injury, Casas held a .244/.344/.514 slash line with six home runs through 22 games. Last summer, the former first-round selection showcased his high potential by posting a solid .263/.367/.490 line with 24 long balls and 65 RBI. Casas should be a reliable first baseman during the final weeks of the season and will be a welcome addition to a Red Sox team that is in the heat of the wild-card race in the American League.

Boston Red Sox manager Alex Cora said on Wednesday that "as of now," first baseman Triston Casas (ribs) won't come off the 60-day injured list to rejoin the team on Thursday for the start of a series against the division-rival Baltimore Orioles at Camden Yards. Casas has been out since late April due to cartilage damage in his left rib cage, but the 24-year-old left-handed slugger is on the cusp of his return to the big-league roster and has gone 8-for-30 in eight minor-league rehab games for Triple-A Worcester. There's no reason why Casas should be floating around on the waiver wire. The former 26th overall pick in 2018 hit 24 home runs and drove in 65 while posting an .856 OPS in 132 games in his first full big-league season for the BoSox in 2023. He will return as the team's starting first baseman when he's ready.
