SCOTTSDALE, Ariz. -- Gregory Infante, who was on the fringe of the picture for the last relief spot in the White Sox bullpen, will be sidelined indefinitely because of a strained left oblique, sustained during Sunday's game against the Rockies.
The right-hander began the sixth inning, but after striking out Kent Matthes, Infante was checked on by head athletic trainer Herm Schneider. Infante then left the game and was replaced by Anthony Carter.
Hector Santiago appears to be the favorite for one of the two open bullpen slots. Brian Bruney, Zach Stewart, Dylan Axelrod and Eric Stults are among the prominent candidates in competition for the final spots.
