On Thursday, the Yankees sent lefty Tyler Webb to the Milwaukee Brewers in exchange for the right-handed hitting Cooper, 26, who was assigned to Class AAA Scranton/Wilkes-Barre. Both players are in Triple-A at the time of the deal.
He has never appeared in the majors, but the Yankees have a pressing need at first base.
The Brewers have been searching for relief help, and get an interesting prospect who is controllable for the near future.
Cooper was a sixth round draft pick out of Auburn University back in 2013. It's not a major deal, but is one that adds pitching depth to the organization and, potentially, a valuable lefty specialist to the big-league bullpen.
Cooper, meanwhile, is having a terrific season at the Triple-A level for Colorado Springs.
For most clubs, the corner infield positions are usually two major sources of power and production in the lineup, but with the constantly changing personnel at first along with Chase Headley's streaky offensive contributions, the Yankees have tried to make the best of a hard situation as the injuries mount. NY was facing a depth chart after the All-Star break that was headed by rookie Ji-Man Choi and supported by struggling utility infielder Rob Refsnyder and backup catcher Austin Romine.
Cooper, 26, has played 75 games for the Brewers' Triple-A affiliate so far, and has hit.366 (tops in Triple-A) with 29 doubles, 17 homers, 82 RBI and a slugging percentage of.652.
