"On the 2-1 pitch is when I felt it. I knew something was wrong," said Beckham. "I stepped out and took a swing, and I kind of realized it wasn't going to be a good swing.
"Obviously, I swung at the next pitch and got out of there. Just some pain in my left wrist."
X-rays showed no structural damage in the left wrist, although an MRI had not yet been performed. Manager Robin Ventura indicated that Conor Gillaspie would start at third on Wednesday, with Jeff Keppinger moving to second, as Beckham's definite return is unknown.
"Probably not tomorrow for sure," said Ventura. "Then, after that, [we'll] kind of check him on a day-to-day basis."
"I've been icing it for the last four hours, or however long we've been out. I've been doing a lot of contrasts," Beckham said. "There's no structural damage, but there is definitely some pain. It's going to take a couple of days. It hurts now just standing here."
