Los Angeles Dodgers vs. Arizona Diamondbacks Prediction – August 9, 2026
The Los Angeles Dodgers make the trip to Chase Field to take on the Arizona Diamondbacks in what shapes up to be a compelling Sunday afternoon matchup. While the Dodgers enter as the slight favorite according to our WP Baseball Predictor model, Arizona has a compelling case to cover — and potentially steal — this game. Here's everything you need to know before first pitch.
Starting Pitcher Matchup
Justin Wrobleski (Dodgers)
Justin Wrobleski takes the hill for Los Angeles, posting an xFIP of 3.93 on the season. That figure reflects a pitcher who has been genuinely solid at preventing runs when accounting for the factors within his control, including strikeout rate and walk tendencies. Wrobleski's underlying metrics suggest he is performing close to the top of what the Dodgers' rotation can offer on a given night, and he'll need to deliver with Los Angeles carrying a strong team FIP of 4.10 and a team ERA of 3.72.
Eduardo Rodriguez (Diamondbacks)
Eduardo Rodriguez counters for Arizona with an xFIP of 4.05 — marginally higher than Wrobleski's, but still a respectable mark that indicates a capable mid-rotation arm. Rodriguez will need to lean on his experience to navigate a Dodgers lineup that carries a formidable team wOBA of .333. The gap between the two starters is narrow, making pitching efficiency and bullpen management critical factors in tonight's outcome.
Why WP's Model Favors the Diamondbacks +1.5
Despite the Dodgers holding a 56.6% win probability to Arizona's 43.4%, the WP Baseball Predictor's official pick is the Diamondbacks at +1.5 on the run line. The reasoning is straightforward: this is not a strong favorite situation. When win probability sits in the mid-50s, the favorite wins often enough — but not convincingly enough — to justify laying runs consistently.
Arizona's case for covering is further supported by the run-line cushion. Even in a Dodgers victory, the Diamondbacks have a reasonable chance of keeping the game within a single run given the closeness of the starting pitcher matchup. Rodriguez's xFIP of 4.05 is comparable to Wrobleski's 3.93, meaning neither staff ace holds a commanding edge. Combined with Arizona's home field advantage at Chase Field, the +1.5 line offers genuine value on the Diamondbacks side.
Injury Report: Key Absences to Watch
Both rosters are dealing with notable absences heading into this contest.
Dodgers Injuries
- Chris Campos – Undisclosed, 7-Day IL
- Wyatt Crowell – Undisclosed, 7-Day IL
- Kendall George – Knee injury, Out
- Peter Heubeck – Undisclosed, 7-Day IL
- Will Klein – Elbow, 15-Day IL
Diamondbacks Injuries
- Yordin Chalas – Undisclosed, 7-Day IL
- Aramis Garcia – Undisclosed, 7-Day IL
- Lourdes Gurriel Jr. – Thigh, 10-Day IL
- Drey Jameson – Hip, 15-Day IL
- Jordan Lawlar – Hamstring, 10-Day IL
Arizona's injury list is particularly concerning. The absence of Jordan Lawlar from the middle infield and Lourdes Gurriel Jr. from the lineup weakens the Diamondbacks' offensive depth, which already trails Los Angeles with a team wOBA of .308 compared to the Dodgers' .333. Los Angeles's bullpen losses — particularly Klein on the 15-Day IL — could slightly limit their late-game options as well.
Dark Horse Home Run Picks
Max Muncy (Dodgers)
Muncy is our dark horse power pick for Los Angeles. A proven left-handed bat with legitimate pull-side pop, Muncy has the profile to punish a right-handed starter and take advantage of Chase Field's conditions.
Corbin Carroll (Diamondbacks)
Carroll is Arizona's dark horse selection. His combination of speed and emerging power makes him a genuine threat to go deep, particularly at home where he's most comfortable in the lineup.
Final Prediction
This is a tight matchup with no dominant favorite in sight. The WP Baseball Predictor model gives the Dodgers the edge in win probability at 56.6%, but the smart play is Diamondbacks +1.5. With comparable starting pitchers, meaningful injuries on both sides, and Arizona at home, the run line offers real value on the D-backs to keep this game close regardless of the final outcome.
