T.R. Sullivan says that Julio Borbon is traveling to Anaheim to meet the Rangers for tomorrow's game, and is expected to be activated, either in place of Nelson Cruz (who would be sent to the disabled list) or Doug Mathis.
Sullivan also says that Jarrod Saltalamacchia is dealing with a "dead arm," which resulted in him being pulled from today's game, and I suppose the Rangers would have to look at adding a catcher as well, if it looks like Salty could miss time.
