Matchup Breakdown
Diamondbacks Outlook
Arizona’s offense has been inconsistent, but their power numbers still rank among the league’s best. With a .433 slugging percentage and 272 doubles (4th in MLB), players like Corbin Carroll and Ketel Marte remain threats to change a game with one swing.
Eduardo Rodriguez (9-8, 4.91 ERA) will start, coming off six scoreless innings against Philadelphia. He’s pitched well historically vs. San Diego (2.30 ERA in three starts), but Arizona’s bullpen has been a disaster — 29 blown saves this year, including eight in the ninth inning, both league worsts.
Padres Outlook
San Diego is looking to stay sharp heading into October. Michael King (5-3, 3.57 ERA) gets the nod after tossing five shutout frames vs. the White Sox last week. He’s been excellent against Arizona in his career, with 11 scoreless innings over two starts.
Offensively, Fernando Tatis Jr. made his return in a big way Friday with a grand slam. He’s joined by Manny Machado (26 HR, 93 RBI) and Luis Arraez, who continues to provide on-base consistency. The Padres’ pitching staff leads MLB in batting average against (.224) and sits 3rd in ERA (3.65).
Key Battle
The Diamondbacks’ power bats vs. San Diego’s elite pitching. Arizona has punished mistakes, but King’s ability to keep the ball down and the Padres’ bullpen depth could tilt the balance late.
