"He should be fine," manager Dusty Baker said. "He looks like a racehorse with the tape on his ankle. Other than that, he said it didn't swell much, which is good."
Latos injured the ankle after delivering a pitch to the Astros' Marwin Gonzalez in the fifth inning on Monday. He came up limping but threw a few warmup pitches and finished the inning before making way for pinch-hitter Miguel Cairo.
After the game, Latos said his high pitch count -- he was at 95 pitches through five -- was the reason he left the game, not the ankle. He did notice the sprain after it happened, though.
"I felt it the rest of the inning, especially the last couple of pitches," Latos said Monday. ""But it's fine now."
The Reds' starters have all stayed relatively healthy this season. The Marlins are the only other team in the Majors to have used just five starting pitchers this season, but they traded starter Anibal Sanchez to the Tigers on Monday. Sanchez's former spot in the Marlins' rotation comes up Saturday, so if Homer Bailey, Bronson Arroyo and Johnny Cueto make their scheduled starts in the next three games, the Reds will become the only team in the Majors with their original rotation intact.
