Dodgers vs. Diamondbacks Prediction: Wrobleski Looks to Close Out Series Sunday at Chase Field

The Dodgers just snapped a seven-game losing streak in extra innings on Saturday, and now they need to prove it wasn’t a one-off before this series — and their NL West cushion — slips away.

Quick take:

• Pick: Dodgers -1.5
• Why: Justin Wrobleski has been steady all year and Arizona’s lineup has gone cold against left-handed pitching in this series
• The number to watch: The Dodgers are outscoring opponents by 139 runs this season, the best run differential in the NL West by a wide margin

Los Angeles (70-47) heads into the series finale at Chase Field still sitting atop the NL West, but the margin is thinner than it was a month ago. Arizona (62-56) has crept to within 7.5 games and has won two of the first three games in this series, including a wild extra-innings edge for the Dodgers on Saturday that snapped a brutal seven-game skid.

Sunday’s rubber match features one of the better pitching matchups this series has offered. Justin Wrobleski takes the ball for Los Angeles, and Eduardo Rodriguez counters for the D-backs in a game that closes out a four-game set with real playoff-positioning stakes for both clubs.

Why Vegas Still Trusts the Dodgers Despite the Skid

The betting market hasn’t lost faith in Los Angeles, even after that rough stretch. The Dodgers opened as roughly -184 favorites on the moneyline with a runline of -1.5, while Arizona sits at +170 as the home underdog — notable given the D-backs have actually won this series so far. The total sits at 8.5 runs, reflecting two offenses that have combined for some high-scoring affairs this week, including Friday’s 4-3 Arizona win and a 2-1 grinder in extras on Saturday.

Wrobleski’s Command Against a Banged-Up D-backs Rotation

Wrobleski has quietly turned into one of the more reliable arms in the Dodgers rotation, sitting at 11-3 with a 3.31 ERA and a tidy 1.068 WHIP. That steadiness matters more than usual right now — Los Angeles is without Blake Snell, Tyler Glasnow, and Kris Bubic, all sidelined with injuries that have forced manager Dave Roberts to lean on depth arms for much of the summer. Wrobleski has been the exception, not the problem.

Arizona counters with Eduardo Rodriguez, who has been arguably better on paper at 10-4 with a 2.71 ERA. But the D-backs are dealing with their own attrition — Zac Gallen, Corbin Burnes, and Ryne Nelson are all out, and Merrill Kelly exited Friday’s start with a leg cramp. Ketel Marte has still been the engine of Arizona’s offense, hitting for 19 home runs and 62 RBI, and he’s had success against Dodgers pitching in past meetings this year.

Los Angeles owns a +139 run differential this season, more than double the gap of any other NL West club.

That differential is the real signal underneath the recent slump. The Dodgers haven’t suddenly become a bad team; they hit a rough patch against Chicago and dropped the first two of this series before Saturday’s escape act. Shohei Ohtani is hitting .294 with 26 home runs, and Freddie Freeman is at .304 with 15 homers — the middle of this lineup is still functioning even when the pitching staff is stretched thin.

Arizona has shown it can hang, though. The D-backs took two of three from a desperate Dodgers club and have won each of the last two head-to-head meetings before this series, including a lopsided 9-3 win back on July 10 when Rodriguez shut down the Dodgers lineup for six innings. Corbin Carroll has been a nuisance all year with 16 home runs and enough speed to change a game late, and it wouldn’t shock anyone if Sunday turns into another one-run affair given how the last three have gone. For bettors looking at live MLB odds before first pitch, the number could move depending on late lineup news.

There’s also a personnel wrinkle worth watching. Los Angeles has been without catcher Will Smith since June and lost depth piece Dalton Rushing to a UCL issue earlier this month, which has quietly thinned out the bottom of the lineup on days the regulars need a breather. Arizona, for its part, is still missing outfielder Lourdes Gurriel Jr. and has had Jordan Lawlar working back from a hamstring strain rather than available off the bench. Neither issue is likely to decide Sunday’s outcome outright, but both speak to why these two rosters have looked less dominant than their preseason expectations suggested by early August.

Home-field factors matter here too. Chase Field’s retractable roof and mild late-summer conditions inside tend to favor pitchers who can locate — which lines up well for Rodriguez, but also plays into Wrobleski’s game plan of avoiding hard contact. Neither pitcher is a strikeout artist in the traditional sense; both work off soft contact and command, which is part of why the total sits at a relatively modest 8.5 for a stadium that has produced its share of slugfests this season.

Prediction and Best Bet

Wrobleski’s consistency and the Dodgers’ superior overall roster depth — even missing three rotation pieces — should be enough to close this series out on a positive note, especially with the way Los Angeles’ bats have looked against right-handed pitching this stretch.

The pick:

1. Prediction: Dodgers 5, Diamondbacks 3
2. Best Bet: Dodgers on the moneyline

Take the favorite here — the run differential gap is too wide to bet against for one more game, even with Arizona playing spoiler at home this week.
