Worth noting

• Curt Hasler has enjoyed filling in for White Sox pitching coach Don Cooper, who has been away from the team recovering from diverticulitis, but he would rather Cooper be with the team. The good news is that Cooper is scheduled to rejoin the White Sox on Friday in Chicago.

"Listen, it's the big leagues and that's awesome," Hasler, Chicago's Minor League pitching coordinator, said about his time with the big club. "But I'm hoping Cooper is feeling good. I'm hoping and praying that he's back and ready to go, because not having him here is not the same. No doubt about it."

• Second baseman Gordon Beckham underwent successful surgery at the Cleveland Clinic on Monday to repair the hook of the hamate fracture in his left hand. The expected recovery time for Beckham is six weeks.

• The White Sox have released left-hander Charlie Leesman after designating him for assignment on Sunday to make room on the 40-man roster for infielder Tyler Greene. Leesman is now on waivers, but could ultimately rejoin the club if he goes unclaimed.

In 26 starts at Triple-A Charlotte last season, the 26-year-old was 12-10 with a 2.47 ERA. Chicago selected Leesman in the 11th round of the 2008 First-Year Player Draft.
