When analyzing the markets for the Dodgers and Rockies, Los Angeles clearly stands out based on the underlying data. The Dodgers sport a stellar 3.70 team ERA and a strong .765 team OPS, completely overshadowing Colorado’s struggles on the mound (5.52 ERA) and at the plate (.741 OPS). Los Angeles enters the August 19 slate with momentum, highlighted by Shohei Ohtani hitting his 30th home run of the season in a recent 7-6 Dodgers victory.
In another marquee matchup, the New York Yankees visit the Baltimore Orioles. The Yankees’ pitching has been exceptional this season, boasting a 3.24 collective ERA compared to Baltimore’s 4.23 mark, and New York recently secured a 3-1 victory powered entirely by Trent Grisham’s offense.
