1* free pay on the San Francisco Giants...
The San Francisco Giants are just 2.5 games back of the first place Dodgers in the NL West, and they'll look to complete the sweep of a two game set at home against the Astros this afternoon. Houston is really struggling on the road, coming in as losers of nine of their last 10.

Here are my keys to the game:

1. Pitching - Scott Feldman will get the start for the Astros, and he's been one of their worst pitchers this season. Feldman (4-5, 4.46 ERA) gave up a pair of solo home runs in six innings in a no decision versus Oakland in his last appearance. He's 0-1 with a 3.65 ERA over his last four starts. The Giants counter with red hot rookie Chris Heston, who is 5-4 with a 2.57 ERA in 11 starts in San Francisco this season.

2. Previous History - This will be the second time this season that Heston will face Houston, he went the distance, allowing one run on two hits, striking out 10 in a win at Houston earlier this year.

3. X-Factor - The Giants have won eight of the last nine meetings in this series.
