CINCINNATI -- Astros pitcher Edgar Gonzalez left Sunday's game against the Reds prior to the bottom of the sixth inning due to a possible injury.
Gonzalez came out to warm up before the Reds' at-bat in the sixth, but was soon surrounded by the Astros' infield and a few coaches and trainers.
After a brief conversation on the mound, Gonzalez left the game and was replaced by Wesley Wright. There was no word as to what caused Gonzalez's early exit.
Gonzalez tossed five innings and had given up one run on two hits with one walk and six strikeouts. He threw 79 pitches and helped the Astros gain a 5-1 lead.
In his previous outing on Monday -- his first start since 2009 -- Gonzalez lasted 5 1/3 innings against Pittsburgh, allowing one run on five hits. He threw 82 pitches before exiting that game.
Before the game, Astros interim manager Tony DeFrancesco said he felt Gonzalez could go deeper into the game on Sunday.
"I think he can [go deeper]," DeFrancesco said. "I think we can get him into the [sixth], seventh inning and keep his pitch count down."
