GM Rick Hahn confirmed the injury before the series finale with the Washington Nationals on Thursday. He said Beckham will have surgery at some point in the next few days, and the team is going to announce a corresponding roster move Friday in Cleveland.
Beckham apparently injured the wrist on a swing in the second inning of Tuesday's game against the Nationals, likely on a 2-1 pitch from Gio Gonzalez. The infielder finished the at-bat -- striking out -- but remained in the game until leaving in the bottom of the third inning. Initial X-rays were negative, but the MRI gave a different picture.
"I've never actually broken a bone in my body, so when I was moving it around the last couple days, I definitely felt like it's something I've never felt before, and it was," Beckham said. "The MRI just kind of confirmed what I thought. It's frustrating, but it is what is. We'll get the surgery done and I'll be back."
Beckham was batting.316 average in his first seven games.
"It's unfortunate," Hahn said. "I know he's frustrated, but on the plus side of things, this is...something that happens fairly commonly and has a standard recovery process, so once the time elapses, he should be hopefully able to pick right up where he left off."
Manager Robin Ventura also said he felt bad for Beckham due to the infielder's good start as well as the way he helps in the field.
Ventura also said the White Sox likely will put Jeff Keppinger over at second or move him between second and third. They can also use Angel Sanchez at second. He replaced Beckham there after Tuesday's injury. Conor Gillaspie is likely going to see some time at third with Keppinger moving to second.
Ventura also said he's hopeful that Beckham can get back into his good hitting rhythm when returning in about six weeks.
"That's the whole thing: You take six weeks, and now it's like having spring training again, especially not being able to swing the bat," Ventura said. "That will be the test ... to be able to somehow maintain it and have that same feel when you come back."
