A.J. Pollock will have surgery on his fractured right hand in the next few days and Arizona Diamondbacks Manager Kirk Gibson expects the young outfielder to be sidelined about five to eight weeks.
Gibson, speaking before Sunday's game against Cincinnati, said that timetable was just a guess.
The Diamondbacks put Pollock on the 15-day disabled list and purchased the contract of outfielder David Peralta from double-A Mobile (Ala.). Peralta was in the Arizona lineup in left field for Sunday's game, his major league debut.
Pollock, in his second full season in the majors, was hit in the hand by the Reds' Johnny Cueto in the eighth inning of Saturday night's 5-0 loss to Cincinnati.
He had been one of the team's best players over the last month, batting .344 since April 4.
The Oakland Athletics called up catcher Stephen Vogt from triple-A Sacramento and optioned right-hander Fernando Rodriguez back to the minors.
Vogt immediately went into the starting lineup at catcher for the series finale against the Angels as the short-handed A's needed hitters with first baseman Brandon Moss (right calf) and outfielder Josh Reddick (knee) out because of injuries. Both are day to day.
Infielder Nick Punto is also slowed by a sore calf, leaving Oakland with only 10 healthy hitters before the move to bring up Vogt.
The Tampa Bay Rays put right fielder Wil Myers on the 15-day DL because of a sprained right wrist.
Myers was injured on the final play of a 3-2 loss Friday to the Boston Red Sox when his hand slapped the ground as he landed following a collision with center fielder Desmond Jennings. The collision led to a game-ending triple by A.J. Pierzynski in the 10th inning.
Myers, who also sat out Saturday's game, is batting .227 with five home runs and 25 runs batted in this season.
Right-hander Bryan Morris was traded by the Pittsburgh Pirates to the Miami Marlins, who gave up the 39th overall pick in Thursday's draft.
