Dodgers vs. Diamondbacks Prediction: Wrobleski-Rodriguez Rematch Decides Rubber Match at Chase Field

The Los Angeles Dodgers and Arizona Diamondbacks close out their three-game series Sunday afternoon at Chase Field, with first pitch set for 4:10 p.m. ET. The series is tied 1-1 after Arizona took Friday’s opener 4-3 behind Merrill Kelly’s near no-hitter before the Dodgers bounced back Saturday. Los Angeles enters at 70-47 and holds a comfortable lead in the NL West, while Arizona sits at 62-56, still fighting to stay in the division and wild-card conversation. The season series between these two rivals is dead even at 6-6 heading into this 13th meeting of the year, and neither club has been able to pull away in a matchup that has produced tight, low-margin finishes all season.

What the Market Is Saying About This One

Los Angeles opened as a heavy favorite and the number has held, with the Dodgers priced between -141 and -184 on the moneyline depending on the book, and Arizona sitting anywhere from +170 to +125 as the home underdog. The run line has Los Angeles at -1.5 (-114 to +115 depending on the shop) with Arizona getting the extra 1.5 runs. The total sits at 8.5, with the over drawing slightly more support at some books. That gap between moneyline and spread pricing suggests the market expects a competitive, low-scoring game rather than a blowout — a fair read given the pitching matchup on the mound.

Wrobleski and Rodriguez Give This One a Pitcher’s Duel Feel

Justin Wrobleski takes the ball for Los Angeles carrying an 11-3 record and a 3.31 ERA, and he’s been arguably the most reliable arm in a Dodgers rotation that has weathered a rash of injuries. His 1.068 WHIP and roughly seven strikeouts per nine innings reflect a pitcher who limits free passes and lets his defense work. Opposing him is Eduardo Rodriguez, who has quietly turned in one of the better seasons of his career at 10-4 with a 2.71 ERA, the best mark of the two starters. Rodriguez’s WHIP sits a touch higher at 1.240, but he’s been death on left-handed hitters and has kept Arizona in every game he’s started, evidenced by the D-backs’ 14-9 against-the-spread record in his 23 outings with a number attached.

Offensively, the Dodgers lineup still runs through Shohei Ohtani (.294/.398/.547, 26 home runs) and Freddie Freeman (.304/.378/.476), with Mookie Betts sliding to shortstop and Andy Pages providing pop from center field. Arizona counters with Ketel Marte and Corbin Carroll at the top, though both have cooled recently — Carroll is hitting just .211 since the All-Star break despite an expected slugging mark of .469 that suggests better results are coming. Nolan Arenado remains steady in the middle of the order with 17 home runs, and Gabriel Moreno has been a legitimate weapon behind the plate, hitting .303 with an .826 OPS.

Injuries loom over both dugouts. Los Angeles is still missing Blake Snell, Brock Stewart, Blake Treinen and Jake Cousins from an already stretched bullpen, while Arizona is working Michael Soroka back from the injured list and had reliever A.J. Puk officially shut down for the season this weekend. Merrill Kelly is considered day-to-day after Friday’s cramping issue, and closer-caliber arm Justin Martinez remains out as he continues his rehab from elbow surgery. Neither bullpen is at full strength, which raises the stakes on both starters going deep into this one.

The head-to-head history favors the Dodgers, who lead the all-time series 281-214, but nothing about this particular season has come easily against Arizona. This is the 13th meeting between the two clubs in 2026, and both teams have alternated series wins throughout the summer without either establishing real separation. Arizona has actually won three of the last five meetings at Chase Field, a reminder that the D-backs play meaningfully better at home than their overall record might suggest, and Rodriguez in particular has been excellent on his home mound this season.

Prediction and Best Bet

This lines up as a low-scoring, tightly contested finale. Wrobleski has been the more consistent of the two arms in terms of run support and win total, and the Dodgers’ lineup has enough thump at the top to scratch across the extra run or two that decides these games. Arizona’s bullpen questions behind Rodriguez tip the balance toward Los Angeles closing out the series.

• Prediction: Dodgers 4, Diamondbacks 2
• Best Bet: Dodgers on the moneyline

With both starters missing bats and neither bullpen fully healthy, banking on the deeper, more complete Dodgers roster to escape Chase Field with the series win is the safer path than chasing the shorter runline price.
