When evaluating today’s matchups to find genuine market value, we put a lot of stock in the underlying context. In the HOU @ SEA matchup, the Mariners present a statistically strong position due to their dominant pitching and recent divisional momentum. Seattle’s staff boasts an excellent 3.007 ERA and a 1.04 WHIP, significantly outpacing a struggling Astros staff currently carrying a 6.488 ERA and 1.70 WHIP. It goes without saying that Houston’s rotation is in disarray following Grade 2 strains to Cristian Javier and Hunter Brown, forcing them to rely on inexperienced arms like Mike Burrows against Seattle’s ace.
Meanwhile, the Cubs present intriguing longshot value in Philadelphia. Despite the 37.5% implied probability, Chicago actually holds the pitching edge with a 3.425 team ERA and 1.12 WHIP, compared to the Phillies’ 4.299 ERA and 1.26 WHIP. Javier Assad has stepped up admirably for the Cubs’ rotation in place of the injured Matthew Boyd. Furthermore, Chicago’s batters have slightly outperformed Philadelphia in getting on base, carrying a .321 OBP against the Phillies’ .307 OBP. With fan frustrations brewing around a seemingly joyless Phillies squad, trading shares on the CHC prediction is an appealing strategic play.
