3:24pm: Both Warren and Almonte have indeed been called up. Teixeira has been placed on the DL and Bootcheck has been designated for assignment.
2:16pm: Via Sweeny Murti: The Yankees will indeed place Mark Teixeira on the 15-day DL with wrist inflammation today. They will use the injury to bring long-reliever Adam Warren back from Triple-A before the ten-day waiting period expires. Murti also hears outfielder Zoilo Almonte could be called up as well, though the team has yet to announce anything. Removing Chris Bootcheck from the roster would be the obvious corresponding move there.
