The Orioles host Houston on Memorial Day, coming off back-to-back losses in Miami. They've been much better at home in Baltimore, posting a 13-9 record at Camden Yards. I like the Orioles as a home dog in this spot.

Here are my keys to the game:

1. Pitching - The Orioles hand the ball to Wei-Yin Chen, who has pitched much better than his numbers show. Chen (1-3, 2.90 ERA) allowed four runs on eight hits over seven innings in a loss to Seattle his last time out. While he's lost consecutive starts, the Orioles have only given him a total of three runs in those games. He's owned the Astros, going 3-0 with a 2.75 ERA in his last three starts against them. Houston will counter with Dallas Keuchel, who is having a breakout season. Keuchel though came into 2015 with a record of 10-14, 4.66 ERA on the road over the previous three seasons.

2. Feast or Famine - The Astros are relying heavily on the long ball, as they rank last in the American League with a .231 team batting average.

3. X-Factor - The Orioles have won 10 of their last 12 home games versus Houston.

Selection: This is a play on the Baltimore Orioles +1.5 (8*)
