With opening day just around the corner, the list of notable players who are going to be absent keeps growing.

World Series MVP Steve Pearce will start the season on the injured list for the Boston Red Sox, and Arizona Diamondbacks outfielder Steven Souza Jr. went down with a knee injury Monday night when he slipped on home plate.

Earlier in the day, Baltimore put scheduled opening-day starter Alex Cobb on the 10-day injured list with a strained right groin.

Pearce exited an exhibition game last weekend due to discomfort in his left calf. The right-handed batter normally platoons with lefty-hitting Mitch Moreland at first base, but the Red Sox will begin defense of their championship Thursday in Seattle without Pearce.
