Oscar Colás went on a tear recently for Charlotte with seven homers in his last seven games.

Colás earned a return to the majors, as the Chicago White Sox recalled the outfielder from Triple A on Tuesday.

He slashed .211/.265/.276 with one homer and seven RBIs in 25 games with the Sox before being optioned to Charlotte on May 2. He hit .140 (6-for-43) in his last 15 games.

At the time, manager Pedro Grifol said Colás needed to slow the game down.

“This is a tough level to play at,” Grifol said on May 2. “Some guys get here and produce right away, some guys don’t. Some guys need to go back down and continue to develop.”

The No. 2 prospect in the organization according to MLB.com, Colás is slashing .293/.358/.508 with nine homers and 29 RBIs in 48 games with the Knights.

In the corresponding move, the Sox optioned outfielder Clint Frazier to Charlotte. Frazier slashed .197/.303/.242 with three RBIs in 33 games after being called up on May 21.
