The Texas Rangers are trying to bolster their bullpen, which went into Saturday with a 5.30 ERA. One reliever they are looking at is Marlins right-hander Guillermo Mota, who has been unhappy about his setup role since returning from the disabled list. Mota is in Jack McKeon's doghouse, as he has been vocal about his displeasure with his role. Mota came up with the Dodgers and came over with Paul Lo Duca in the Brad Penny trade.
