Houston's Norris leaves start against SF

SAN FRANCISCO (AP) Houston pitcher Bud Norris left his start against San Francisco on Tuesday with a sprained left knee.

Norris appeared to pull up after chasing a popup in foul territory by Giants pitcher Madison Bumgarner. Norris was unable to make the catch and met with a team trainer and manager Brad Mills before attempting a few warmup pitches. He then left the field and was taken to the Astros clubhouse.

Before leaving, Norris allowed three runs and walked three with one hit batter. He gave up a home run to Bumgarner leading off the third inning, only the seventh home run hit at home by the Giants this season.
