Astros vs Mariners Prediction

The Astros and Mariners have been quiet offensively lately and that’s due to change given the talent in both lineups. Woo has a 4.02 ERA and 1.00 WHIP on the season, but that ERA jumps to 4.50 on the road along with a .271 allowed batting average. Imai has pitched just 8.2 innings in his MLB career, but he has a 7.27 ERA and 2.08 WHIP. He’s walked 13 batters during those frames. This feels like a spot where the bats wake up and we see some offense. Give me the over in game 2 between the Astros and Mariners.
