Dodgers vs Diamondbacks Pick & Prediction for Aug 31 | Sweep Alert?

by | Aug 31, 2025 | mlb

Yoshinobu Yamamoto LA Dodgers Starting Pitcher

The Arizona Diamondbacks (68-69) head into Sunday’s series finale at Dodger Stadium with a chance to complete a shocking sweep of the NL West-leading Los Angeles Dodgers (77-59). After taking the first two games behind stellar pitching performances, Arizona now looks to Brandon Pfaadt to finish the job against Japanese star Yoshinobu Yamamoto. I’ve identified several key edges in this matchup that make for appealing betting opportunities, especially with the Dodgers’ offense showing concerning signs during their current mini-slump.

Quick Picks:

  • Best Bet: Dodgers -1.5 (-105) ★★★★☆
  • Top Prop: Yoshinobu Yamamoto Over 6.5 Strikeouts (+115) ★★★★☆
  • Value Play: Under 9.0 Runs (-115) ★★★☆☆

Arizona Diamondbacks vs Los Angeles Dodgers Betting Odds & Latest Line Movement

Market Arizona Diamondbacks Los Angeles Dodgers
Moneyline +178 -218
Run Line +1.5 (-115) -1.5 (-105)
Total Over 9.0 (-105) Under 9.0 (-115)

Opening Line: Dodgers -210, Total 8.5

Sharp Money Analysis: Where Pro Bettors Are Placing Their Wagers

Despite the Dodgers dropping two straight to Arizona, sharp money continues to show confidence in Los Angeles for the series finale. The opener of -210 has been pushed slightly to -218, indicating professional bettors aren’t overreacting to the short-term results. More telling is the total, which opened at 8.5 but has been bet up to 9, suggesting sharps see value in the over despite Yamamoto’s presence on the mound. The run line price of -105 for Dodgers -1.5 also indicates professional money believes Los Angeles can win by multiple runs today.

Pitching Matchup: Brandon Pfaadt vs Yoshinobu Yamamoto – Who Has the Edge?

Arizona Diamondbacks: Brandon Pfaadt (12-8, 5.24 ERA)

  • Has struggled with consistency all season, with an alarming 5.24 ERA across 142.2 innings
  • Home run vulnerability remains a major issue (1.7 HR/9 this season)
  • Decent K/BB ratio of 117:32 shows his control is solid, but contact quality is problematic
  • Has been hit hard by Dodgers this season, allowing 9 runs in 9.2 innings across two starts

Los Angeles Dodgers: Yoshinobu Yamamoto (11-8, 2.90 ERA)

  • Showing why the Dodgers invested $325 million in him with a stellar 2.90 ERA
  • Elite strikeout production with 157 Ks in 139.2 innings (10.1 K/9)
  • Impressive 1.07 WHIP demonstrates his ability to limit baserunners
  • Has been more vulnerable at home (3.22 ERA) than on the road (2.59 ERA)

Advantage: Significant edge to Los Angeles. Yamamoto has been among the most consistent starters in the National League, while Pfaadt’s ERA over 5.00 presents a major liability for Arizona, especially at Dodger Stadium where the ball carries well.

Bullpen Breakdown

The Diamondbacks bullpen has been a revolving door all season, using a franchise-record 16 different pitchers in save situations. Their current closer appears to be Jake Woodford, who recorded just his second save of the season last night. The Dodgers’ bullpen is in better shape with Tanner Scott (20 saves) and Kirby Yates forming a solid late-inning tandem, though Yates did struggle in yesterday’s outing. With Brock Stewart on the IL with shoulder inflammation, the Dodgers’ middle relief has been somewhat vulnerable. Still, Los Angeles holds the overall advantage in bullpen depth and reliability, especially if they can get a quality start from Yamamoto to limit the bullpen’s workload.

Key Betting Trends & Team Statistics That Matter

  • The Dodgers are 42-24 at home this season, still one of the best home records in baseball
  • Arizona has won the first two games of this series despite being outscored by 82 runs overall on the season
  • Brandon Pfaadt has a troubling 6.15 ERA in day games this season (vs. 4.88 ERA at night)
  • Yoshinobu Yamamoto has a dominant 44:11 K:BB ratio over his last 6 starts
  • The Dodgers have scored just 1 run in their last 18 innings against Arizona pitching
  • Arizona is 31-34 on the road this season, but has won 4 of their last 6 away from Chase Field
  • The under is 7-3 in the last 10 meetings between these teams at Dodger Stadium

Yoshinobu Yamamoto: Japan’s Rising Star Faces Critical Test

Yoshinobu Yamamoto has stepped up admirably in recent weeks as the Dodgers have navigated injuries to their rotation. After some early-season adjustments to MLB, he’s now pitching like the ace Los Angeles expected when they signed him to a massive contract. His splitter has been especially effective, generating a 43.2% whiff rate that ranks among the best in baseball for any single pitch. What makes today’s start particularly important is the Dodgers’ need to avoid a sweep and maintain their slim lead over the Padres in the NL West. In high-pressure starts this season, Yamamoto has delivered a 2.41 ERA, showing the composure that made him a superstar in Japan.

Dodger Stadium Factor: How the Venue Influences Today’s Game

Dodger Stadium plays as a pitcher-friendly park for run scoring (0.940 park factor), but actually boosts home runs significantly with a 1.122 HR factor. This creates an interesting dynamic for today’s matchup. Pfaadt’s primary weakness is his home run vulnerability, making Dodger Stadium a particularly dangerous venue for him. Yamamoto, meanwhile, has done an excellent job limiting the long ball (0.8 HR/9), negating one of the park’s few hitter-friendly characteristics. The afternoon start time (1:10 pm local) also typically favors pitchers at Dodger Stadium, with the marine layer often dissipating and creating clearer visibility compared to night games. These factors all point to Yamamoto having significant environmental advantages over Pfaadt today.

Expert Prediction & Best Bets for Diamondbacks-Dodgers Showdown

Primary Play: Dodgers -1.5 (-105)

I’m backing the Dodgers on the run line today as they look to salvage the series finale. Los Angeles is due for an offensive breakout after scoring just one run in each of the first two games. Pfaadt’s 5.24 ERA and home run issues make him vulnerable at Dodger Stadium, while Yamamoto gives the home team a significant pitching advantage. The price of -105 offers solid value on a team that should be motivated to avoid a sweep at home. I expect the Dodgers to win by multiple runs.

Strong Value Play: Under 9 Runs (-115)

Despite the total moving up from 8.5 to 9, I still see value on the under. Yamamoto has been outstanding recently, and while the Dodgers should score more than they have the last two days, I don’t see this turning into a slugfest. Dodger Stadium suppresses overall run scoring, and the Diamondbacks lineup has been inconsistent all season. A final score in the neighborhood of 5-2 Dodgers seems most likely, keeping this under the total.

Worth Considering: Yoshinobu Yamamoto Over 6.5 Strikeouts (+115)

This prop offers excellent value at plus money. Yamamoto has exceeded 6.5 strikeouts in four of his last six starts, and the Diamondbacks rank 8th in MLB in strikeout rate against right-handed pitching. His splitter has been a devastating out pitch, and with the pressure of avoiding a sweep, I expect Yamamoto to attack with his best stuff. Arizona has also been more aggressive at the plate on the road, which should create more swing-and-miss opportunities.

Player Props Worth Targeting in Today’s Matchup

Player Prop Odds Rating
Yoshinobu Yamamoto Over 6.5 Strikeouts +115 ★★★★☆
Shohei Ohtani To Hit a Home Run +340 ★★★☆☆
Brandon Pfaadt Under 5.5 Strikeouts -120 ★★★★☆
Freddie Freeman Over 1.5 Total Bases +100 ★★★★☆
Corbin Carroll To Record a Hit -190 ★★★☆☆

Final Thoughts: Dodgers’ Ace Ready to Stop the Bleeding

While Arizona has been impressive in taking the first two games of this series, I see the Dodgers bouncing back emphatically today behind Yamamoto. The pitching matchup heavily favors Los Angeles, and the Dodgers’ offense is too talented to stay quiet for three straight games. Pfaadt’s home run vulnerability at Dodger Stadium could lead to a quick early deficit for the Diamondbacks. Don’t overreact to short-term results – the fundamental advantages still lie with the home team.
