Diving into the biggest mismatch of the slate, the data shows exactly why Los Angeles is favored so heavily over St. Louis. At the plate, the Dodgers have been far more productive, boasting a .756 team OPS and 678 total runs scored, compared to the Cardinals’ .700 OPS and 623 runs. The gap is just as wide on the mound. Los Angeles pitchers bring a combined 3.69 ERA and a stellar 1.16 WHIP into the matchup. Meanwhile, the St. Louis pitching staff has struggled to keep runners off the basepaths, logging a 4.24 ERA and a 1.34 WHIP.
Even with the Cardinals recently finding offensive momentum, Los Angeles profiles as the much safer position across all major statistical categories. Furthermore, the Philadelphia and Arizona matchup presents a volatile market; the surging Phillies enter Wednesday with a dominant six-game winning streak, while the Diamondbacks are currently navigating internal friction and fan backlash surrounding the recent restricted-list absence of star Ketel Marte.
