The Rangers have already made a number of changes to their pitching staff, but more could be coming. Texas signed closer Joe Nathan and moved Neftali Feliz into the starting rotation. In addition, many believe free-agent C.J. Wilson will depart. The Rangers "can't be ruled out" on starters like Cubs right-hander Matt Garza, according to Ken Rosenthal. Chicago is believed to be open to moving Garza.
