ATLANTA -- Though Pirates manager John Russell reiterated earlier on Tuesday that Jeff Karstens will make his scheduled start on Wednesday, the Pirates have now decided to hand the ball to recently acquired right-hander Charlie Morton.
According to two sources, Morton will be recalled from Triple-A Indianapolis on Wednesday to take Karstens' spot in the rotation. The fact that Karstens was needed in relief during Monday's 15-inning affair could be playing a role in this decision. But it's no secret that the Pirates were already looking for a way to get Morton into the big league mix.
Pittsburgh is expected to send left-hander Tom Gorzelanny back to Indianapolis, where he can re-enter the Indians' rotation. Karstens would then provide the Pirates with a long-inning option out of the bullpen.
Morton was one of three prospects the Pirates received in last week's trade with Atlanta. With the Braves' Triple-A affiliate, Morton went 7-2 with a 2.51 ERA in 10 starts to begin the year.
Wednesday will mark Morton's first appearance in the Majors this year, though he will be quite familiar with the team he faces. Morton made his Major League debut for the Braves last season and eventually finished the year 4-8 with a 6.15 ERA in 16 appearances (15 starts).
