Jordan Walden (hamstring) could throw a bullpen session as soon as Tuesday. Walden has been playing catch from distances up to 120 feet and thinks he's ready to take the next step. He should be ready for activation not long after he's throwing from a mound again. "It's feeling a lot better just got to keep working on it, get some more strength in there, hopefully I'll be on the mound soon," Walden said.
