With Boston Red Sox catcher
Connor Wong (finger) heading to the 10-day injured list due to a fractured left pinkie finger that he suffered in Monday's 6-2 loss to the division-rival Toronto Blue Jays,
Carlos Narvaez is the presumed starter, according to MassLive's Chris Cotillo.
Blake Sabol is also on the 40-man roster, though, and he's expected to be called up from the minors with Wong heading to the IL. Narvaez, 26, entered the week with a modest four-game hitting streak, but he snapped that after going 0-for-4 in place of the injured Wong on Monday against Toronto. He's now 6-for-18 with four RBI and two runs scored in his first five games of the season, but fantasy managers in two-catcher and AL-only formats shouldn't expect Narvaez to carry them offensively now that he's the favorite for starting duties in Beantown. The Venezuelan was playing in just his 12th MLB contest on Monday.
