BALTIMORE -- Two days before the White Sox travel to Toronto, manager Robin Ventura opted to change his starter for the opener of a three-game series with the Blue Jays. Andre Rienzo was originally scheduled to start, but after he lost his last five starts, while allowing 22 runs in 22 1/3 innings, the White Sox are opting to go with Scott Carroll on Thursday.
Carroll began the season as a starting pitcher and was moved to the bullpen after five starts. He has a 1.83 ERA and .224 batting average against in six relief appearances.
"Scotty's been throwing great," Ventura said.
In five starts to begin the season, Carroll went 1-3 with a 6.15 ERA.
Meanwhile, Rienzo began the season relatively well. In his first six starts, he went 4-0 with a modest 4.11 ERA before unraveling in his last five outings. After allowing four earned runs in just 4 1/3 innings during his most recent start against the Twins on Saturday, Rienzo's ERA climbed to 5.86.
Ventura saw Carroll find enough consistency out of the bullpen to warrant his return to the rotation. This move, he hopes, will let Rienzo do the same.
"At this point, it's probably better for Rienzo to take a break," Ventura said, "go to the bullpen and figure it out."
