Yankees place DH Matt Holliday on the 10-day disabled list
According to manager Joe Girardi, Holliday "tweaked his back" on a swing Friday night, and was unavailable for Saturday night's game against the Indians.
"He tweaked his left side a little bit, so we'll take a day to see where he's at," Girardi said prior to Saturday's game. "He's had some lower back issues before…we hope it's not too long, but we have to make an evaluation on the severity of it."
After that game, however, Girardi said "we will probably DL Holliday," and the team made it official Sunday morning. It marks Holliday's second DL stint this season, as he also missed the final 14 games of the first half while battling a viral infection.
Holliday, 37, is hitting .229 with 16 home runs and 51 RBI in 88 games overall this season, but in 20 games since returning from that previous DL stint, he has posted a slash line of just .136/.165/.198 with one homer and four RBI.
With a short bench on Saturday, the Yankees moved Gary Sanchez into the designated hitter role, and Girardi used outfielder Brett Gardner as the DH on Sunday.
Cooper, 26, was acquired from Milwaukee on July 13 in exchange for LHP Tyler Webb, and made his major-league debut the following night in Boston. Cooper hit .240 with one RBI in eight games before being optioned to Triple-A on August 1, and he was 0-for-7 in two games with the RailRiders.
