Royals manager Trey Hillman announced on Saturday that his star pitcher would be ready to go for a start against the Red Sox on Tuesday, pitching on regular rest.
After taking a line drive to his right arm in his most recent start against Detroit on Thursday, there was some concern as to whether Greinke might be forced to skip a start. Greinke was hit in the fourth inning by a ball off the bat of Miguel Cabrera, but he remained in the game for five scoreless innings, long enough to pick up his 14th victory. The American League Cy Young candidate threw a season-low 77 pitches, leaving as a precautionary measure with a 5-0 lead.
Greinke played catch off flat ground before Saturday's game against the White Sox in Chicago and told Hillman that he felt fine.
"There's a little bit of swelling in his forearm that's continuing to go south," Hillman said. "We're hoping that that's mostly dissipating in the next 72 hours before Tuesday. He's going to throw a real short side [Sunday] off the slope of the mound at regular distance, maybe 15, maybe 20 pitches.
"[Saturday] was flat ground after long toss, and he said if he hadn't known he had been hit there, he wouldn't have noticed, so it's pretty remarkable the way his body feels today. He said his arm feels good. His legs feel good. His back feels good. So he's in line to go Tuesday as long as there's no setbacks tomorrow."
Greinke's 2.14 ERA this season is the lowest in the AL. He is second in strikeouts with 224 and is vying to become the first Royals Cy Young Award winner since David Cone in 1994.
