A minute later, he had a facetious amendment to his report: "No, I threw 102, trying to keep up with 'Ace' Ventura."
That was an allusion to Yordano Ventura, who lit up the radar gun with 100-mph fastballs during his start against the Mariners in Monday night's 6-5 win in 12-innings.
Shields was drilled by a line drive in the third inning on Sunday, but he continued to pitch eight shutout innings in the Royals' 10-inning, 4-0 victory.
"It's going great, man, it's real good," he said. "It's a little swollen, but it's actually gone down pretty good."
It also turns out Ventura developed a fingernail crack on his pitching hand early in Monday night's game.
"He kind of cracked his nail a little bit in the third inning, which is the reason why I got a little nervous," manager Ned Yost said. "But they got it all trimmed up. It was just a little crack, not earth-shaking news."
Ventura is on track to make his third and last start on Saturday night at Chicago.
