The Los Angeles Dodgers arrive at Chase Field needing a response. Los Angeles is 69-46 but has lost six straight, though it still leads the NL West. Arizona is 61-55, 8.5 games back, and has split the first 10 season meetings.
Friday’s matchup centers on Roki Sasaki against Merrill Kelly. Sasaki is 5-5 with a 4.64 ERA and 101 strikeouts, but his post-break form is sharper. Kelly is 8-9 with a 5.04 ERA, and his contact profile favors Los Angeles.
Across current MLB picks and analysis, the Dodgers are -171 favorites, Arizona returns +154, and the total is nine. Los Angeles is -1.5 at -110.
Dodgers vs Diamondbacks Matchup And Schedule
First pitch is scheduled for 9:40 PM ET on Friday, August 7, at Chase Field. SportsNet LA and DBACKS.TV carry coverage. The MLB probable pitchers page confirms Sasaki and Kelly for the series opener.
| Matchup | Date | Time (ET) | Venue | Starting Pitchers |
|---|---|---|---|---|
| Dodgers at Diamondbacks | August 7, 2026 | 9:40 PM | Chase Field | Roki Sasaki vs Merrill Kelly |
The standings create pressure on both sides. Los Angeles needs to halt its six-game slide before Arizona and San Diego gain more ground. The Diamondbacks need home wins against the division leader to turn an 8.5-game deficit into a realistic late-season chase.
Sasaki’s Second-Half Form Changes The Handicap
Sasaki’s full-season ERA hides a meaningful recent improvement. He is 2-0 with a 1.50 ERA across 18 post-break innings, allowing 13 hits and striking out 21. His past three starts produced seven innings of one-run ball against the Mets, 5⅔ scoreless innings against the Yankees, and 5⅓ innings with two runs allowed against Seattle.
His splitter remains the separator. When Sasaki gets ahead, hitters must protect against upper-zone velocity and a pitch that disappears below the barrel. His Statcast pitching profile shows a far cleaner second-half run-prevention line than his early-season results.
Arizona can counter through Ketel Marte and Corbin Carroll, two hitters capable of punishing mistakes before Sasaki reaches two-strike counts. The Diamondbacks’ best path is forcing traffic early, since Sasaki’s season numbers are weaker with runners in scoring position than with the bases empty.
Kelly Faces A Difficult Dodgers Matchup
Kelly’s 5.04 ERA is only part of the concern. Baseball Savant credits opponents with a 45.4 percent hard-hit rate and 13.2 percent barrel rate against him. His strikeout percentage has dropped to 15.3, reducing his ability to escape innings after allowing baserunners.
That profile is dangerous against Shohei Ohtani, Freddie Freeman, Mookie Betts and Kyle Tucker. Los Angeles can attack with damage from both sides and does not need a long rally to create a crooked inning.
Kelly can still survive through sequencing. His changeup and breaking pitches generate chase, and he has years of experience working at Chase Field. His margin is thin if his fastball leaks over the plate.
Dodgers vs Diamondbacks Odds And Betting Lines
| Team | Run Line | Moneyline | Total |
|---|---|---|---|
| Los Angeles Dodgers | -1.5 (-110) | -171 | Over 9 (+100) |
| Arizona Diamondbacks | +1.5 (-110) | +154 | Under 9 (-120) |
Market consensus across the best offshore sportsbooks gives Los Angeles an implied edge tied largely to the starting-pitcher matchup. Laying -171 is expensive for a team riding six losses. The run line offers a better return if Sasaki’s second-half form continues.
The under carries heavier juice at -120. Sasaki can suppress Arizona, but Kelly’s contact profile makes a low-scoring Dodgers night difficult to trust.
Why Dodgers -1.5 Is The Best Bet
The best bet is Los Angeles -1.5 at -110. Sasaki owns the better current form, and Kelly’s hard-contact numbers line up poorly against the Dodgers’ top four hitters.
Los Angeles has lost six straight, but losing streaks do not erase matchup edges. The Dodgers need cleaner relief work and more timely hitting, yet Sasaki can shorten the bullpen requirement by working into the sixth inning.
Arizona’s strongest upset route is attacking Sasaki early and forcing Dave Roberts into middle relief before the game reaches the late innings. If Sasaki settles quickly, Los Angeles should create more scoring chances against Kelly.
A 6-3 Dodgers win fits the pitching and market setup.
Official Prediction: Los Angeles Dodgers 6, Arizona Diamondbacks 3
MLB Best Bet: Los Angeles Dodgers -1.5 (-110)
