Cleto added to help struggling bullpen

CHICAGO -- The struggling Chicago White Sox bullpen got a fresh arm Monday as the team purchased the contract of Maikel Cleto from Triple-A Charlotte.

It will be Cleto’s second stint with the team. He made the Opening Day roster after he was claimed off waivers from the Kansas City Royals during spring training.

Cleto, 25, had a 5.14 ERA over 13 early-season relief appearances for the White Sox before he was designated for assignment on May 10. In 22 appearances at Charlotte, he posted a 5.91 ERA, but had 50 strikeouts, more than two per appearance.

After Sunday’s bullpen meltdown against the Minnesota Twins, when the relievers gave up 15 runs over four innings, the White Sox optioned right-hander Taylor Thompson back to Charlotte.
