Dodgers vs. Diamondbacks Prediction: Wrobleski Looks to Close Out Chase Field Sweep Bid

The Dodgers just snapped a seven-game losing streak in the most Dodgers way possible — grinding out extra innings — and now they need one more before hopping a flight to face the Royals.

Quick take:

• Pick: Dodgers -1.5
• Why: Justin Wrobleski has been a stabilizing force in a rotation full of question marks, and LA’s lineup still overwhelms even a solid Arizona arm
• The number to watch: Wrobleski is 11-3 with a 3.31 ERA this season

Los Angeles enters the series finale at 70-47 and still comfortably ahead in the NL West, but the vibes have been shaky — a seven-game skid before Saturday’s 2-1, ten-inning survival act in the desert. Arizona, sitting at 62-56 and 7.5 games back, has quietly won its last two series openers against the Dodgers and split this set, showing this isn’t the pushover matchup the standings might suggest.

Why Vegas Still Trusts LA in the Desert

The moneyline has Los Angeles as a clear favorite — hovering around -146 to -184 depending on the book — with the spread set at Dodgers -1.5 and the total sitting at 8.5 runs. That number reflects two offenses capable of scoring in bunches, but it also reflects a starting pitching matchup that clearly favors the road team on paper.

Wrobleski’s Quiet Breakout Meets a Desert Lineup That Won’t Back Down

Justin Wrobleski gets the ball for LA, and his season line — 11-3, 3.31 ERA — has made him one of the most reliable arms the Dodgers have had all year, especially with Blake Snell, Tyler Glasnow, and Kris Bubic all working through injuries on the shelf. Eduardo Rodriguez counters for Arizona sporting an even sharper ERA at 2.71, though his 10-4 record and a 1.240 WHIP suggest a pitcher who’s been good, not dominant, and prone to letting a few extra runners aboard.

Offensively, the Dodgers still have serious thump even with Shohei Ohtani sidelined by knee inflammation and biceps discomfort — Freddie Freeman is hitting .304 with 15 home runs, and Andy Pages has quietly emerged as a legitimate table-setter at .270 with 19 homers of his own. Mookie Betts has scuffled at the plate this season, batting just .231, which has put more pressure on the rest of the order to carry the load.

Arizona’s Corbin Carroll and Ketel Marte have combined for 35 home runs, giving the D-backs real thunder even without Zac Gallen and Corbin Burnes anchoring the rotation.

That power duo is legitimate, and Gabriel Moreno hitting .303 behind the plate gives Arizona a lineup that can punish mistakes. But the D-backs are missing key complementary pieces — Jordan Lawlar, Lourdes Gurriel Jr., and Tommy Troy have all spent stretches on the injured list this summer, thinning out the depth around Carroll and Marte. It’s a lineup built around two stars rather than a deep, balanced attack.

Arizona did win the series opener 4-3 on Friday before falling in extras Saturday, so this rubber match arrives with real stakes for the season series and, more broadly, for Arizona’s fading hopes of closing the gap in the West. If bettors are shopping for value elsewhere in the market, the DraftKings promo code page is worth a look before first pitch.

Wrobleski’s track record as a favorite adds another layer worth noting: when he starts and the Dodgers are the moneyline favorite, the club has gone 11-5 this season. That’s a meaningful split for a pitching staff that’s leaned heavily on him as the healthy alternatives dwindled. Bullpen usage matters here too — the Dodgers have had to piece together innings behind their starters more than usual with Blake Treinen, Ben Casparius, and Brusdar Graterol all working back from injury, which puts extra weight on Wrobleski going deep into this one rather than handing the ball to a taxed relief corps in the sixth or seventh inning.

On the other side, Arizona’s bullpen has its own issues to manage. Michael Soroka and Drey Jameson have both cycled through the injured list this season, and closer-caliber arms have been stretched thin as manager Torey Lovullo tries to keep his roster afloat in a playoff race that’s slipping away by the week. Every extra out Rodriguez can squeeze out of his start matters more for Arizona than it typically would, because the alternative is leaning on a taxed bullpen against a Dodgers lineup that punishes mistakes late in games.

Prediction and Best Bet

The Dodgers’ offense, even without Ohtani in the lineup, has enough thump up and down the order to string together the two or three runs Wrobleski needs, and Rodriguez’s WHIP suggests LA can manufacture extra chances even against a pitcher with a shiny ERA. Arizona’s lineup can strike for a couple of runs off any starter, but without full length from its rotation and without its full complement of role players, matching Los Angeles run-for-run over nine innings feels like a tall order two days removed from an extra-inning heartbreaker.

Tue, Sep 15 • 6:40 PM	Spread	Money	Total
Los Angeles Dodgers	-2 (-109)	-230	O 8.5 (-114)
Cincinnati Reds	+2 (-112)	+205	U 8.5 (-107)

The pick:

1. Prediction: Dodgers 5, Diamondbacks 3
2. Best Bet: Dodgers -1.5

Wrobleski’s steady season and LA’s superior lineup depth make the Dodgers the play to close out this series in Chase Field.
