The Tampa Bay Rays defeated the Houston Astros 3-1 last night, and I expect another low-scoring contest at Tropicana Field Saturday afternoon when the two teams will square off in the middle game of this three-game series.

Here are my keys to the game:

1. Pitching - The Astros will hand the ball to their ace Dallas Keuchel (11-3, 2.14 ERA) who's been exceptional all season long. He has the lowest ERA in the American League and had tossed 19 shutout innings before giving up three runs in six innings his last start. The Rays will counter with Jake Odorizzi (4-5, 2.47) who's had a great season as well. He will make his first start since June 5 due to an oblique injury, and what better place to make the comeback than at the Trop where he's compiled a 1.64 ERA over five starts this season.

2. Houston's Bats - The Astros have scored only 17 runs over their last seven games with nine of them coming in a 9-4 win at Cleveland. They've scored four over their last four games.

3. X-Factor - 10 of the last 11 meetings at the Trop have gone under the total.

Selection: This is a play on HOU@TB to go UNDER the total (10*)
