Alex Bregman left the first game of the Boston Red Sox' doubleheader against the Baltimore Orioles on Friday with a quad injury, and it seems like it could lead to an extended absence.

After Alex Bregman suffered a right quad injury during Friday's game against the Orioles, the Red Sox have decided to call up prospect Marcelo Mayer, ESPN's Jeff Passan reported. Mayer is the second-ranked prospect in Boston's system and is considered a top-10 prospect in all of baseball.

Here's the emotional video of Triple-A player Marcelo Mayer hearing that he's been called up to play for the Red Sox.

The Orioles used their 42nd player last night when Trevor Rogers stepped on the mound to warm up for Game 2 of the doubleheader. They had Terrin Vavra on the bench and Yaramil Hiraldo in the bullpen.

On the lookout for first base depth, the Red Sox made a minor trade Thursday for a player who hit 16 homers for the A's two years ago.

One day after Red Sox reliever Liam Hendriks took to social media to condemn offensive messages made against him and his family, manager Alex Cora empathized with his player. Cora spoke Friday ahead of the first game of a doubleheader against Baltimore at Fenway Park.

Masataka Yoshida took a big step toward returning to the Red Sox on Wednesday. But another position player had a setback and won't be back as soon as once thought.
