Josh Hamilton's home run in the 10th inning gave the Angels a 6-5 win over the Houston Astros on Saturday night at Angel Stadium.

Hamilton's blast off Astros reliever Josh Fields was his seventh career walk-off hit and his second this season. He also hit a walk-off homer July 6 at Angel Stadium against the Boston Red Sox.

His latest homer came after a play in the ninth inning that illustrated why more instant replay is coming to baseball.

The score was tied 5-5 at Angel Stadium when Houston's L.J. Hoes singled to right field and tried to stretch it into a double.

Angels right-fielder Collin Cowgill threw to Erick Aybar who tried to tag Hoes on the back. Second base umpire Eric Cooper said the tag missed and called Hoes

safe.

But then the umpires huddled and ruled that Aybar had in fact tagged Hoes out. Houston Manager Bo Porter argued vehemently but the Angels got out of the inning unscathed.

The Angels' scoring was led by Mark Trumbo who had a solo home run and a two-run triple and Aybar who had two run-scoring hits including a single that scored Mike Trout to tie the game 5-5 in the seventh inning.

Angels starting pitcher Garrett Richards was roughed up by the Astros for five runs and 12 hits in his six-plus innings.

Trumbo hit his home run off Houston starter Dallas Keuchel to deep center field then drove in Cowgill and Trout with his triple in the third inning. Aybar's double scored Trumbo.

Houston parlayed four consecutive singles for two runs against Richards in its half of the third inning.

In the fifth inning after Brett Wallace hit a two-run homer to tie the score 4-4 Jose Altuve singled and Chris Carter hit a deep fly ball that Cowgill appeared set to catch on the run.

But Cowgill apparently lost the ball in the lights because it sailed over his head Altuve scored and Houston took the lead.
