SAN FRANCISCO -- Astros starting pitcher Bud Norris was removed from Tuesday's game against the Giants in the fourth inning with a left knee sprain.
Moments before being taken out of the game, Norris chased down a popup off in foul territory after catcher Jason Castro lost the ball off the bat. Norris sprinted after the pop in front of the third-base dugout and was unable to catch it while lunging forward.
Norris threw a few warmup pitches for manager Brad Mills and athletic trainer Rex Jones before leaving the game. He pitched 3 1/3 innings and allowed three hits and three runs, including a home run to pitcher Madison Bumgarner. He threw 80 pitches.
Norris, who grew up in the Bay Area cheering for the Giants, was pulled from his May 31 start against the Rockies with a strained hip flexor. He was able to make his next start, giving up seven hits and four runs in six innings Wednesday against the Cardinals.
