The Pittsburgh Pirates (20-36) head into the rubber match of their three-game series against the Arizona Diamondbacks (27-28) at Chase Field on Wednesday afternoon. This pitching matchup features a fascinating contrast: Pittsburgh’s elite prospect Paul Skenes bringing his electric arsenal against Arizona’s struggling ace Zac Gallen. After the Pirates’ stunning 9-6 comeback win on Tuesday, where they erased a six-run deficit with a seven-run eighth inning, they’ll look to claim the series behind their young phenom. With Skenes’ dominance and Gallen’s ongoing struggles, I see significant value on the road underdog despite Pittsburgh’s overall poor record.

Sharp Money Analysis: Where Pro Bettors Are Placing Their Wagers
Despite the lopsided moneyline odds, there’s been some interesting line movement since this opened. The Diamondbacks have been bet up from -245 to -267, suggesting strong public backing for the home team. However, I’m seeing some sharp resistance on the total, which opened at 8 and has ticked up to 8.5 despite two elite arms being on the mound. This suggests professional bettors might be expecting more offense than the pitching matchup indicates on paper. The most telling movement is on the run line, where the Pirates +1.5 has moved from +125 to +110, indicating sharp money respects Skenes’ ability to keep this game close.
Pitching Matchup: Paul Skenes vs Zac Gallen – Who Has the Edge?
Pittsburgh Pirates: Paul Skenes (3-5, 2.36 ERA)
- Electric rookie has been dominant despite his losing record with 70 strikeouts in 68.2 innings
- Elite 0.95 WHIP demonstrates his ability to limit baserunners
- Has allowed 2 or fewer earned runs in 9 of his 11 starts this season
- Coming off 8 IP, 1 ER, 10 K performance against Philadelphia
Arizona Diamondbacks: Zac Gallen (3-6, 5.25 ERA)
- Former Cy Young contender struggling mightily with a 5.25 ERA and 1.36 WHIP
- Command issues persist with 29 walks in 61.2 innings (4.2 BB/9)
- Has allowed 4+ earned runs in 5 of his last 7 starts
- Opponents hitting .276 against him over his last 5 outings
Advantage: Significant edge to Pittsburgh. Skenes has been everything advertised as an elite prospect, while Gallen appears to be fighting mechanical issues that have plagued him all season.
Bullpen Breakdown
The Diamondbacks’ bullpen is reeling after Tuesday’s epic collapse, where they surrendered seven runs in the eighth inning to blow a six-run lead. Kevin Ginkel and Jalen Beeks were particularly ineffective, and manager Torey Lovullo will have limited high-leverage options after using four relievers yesterday. Pittsburgh’s bullpen, despite their overall struggles this season (4.62 ERA, 25th in MLB), should be relatively fresh with Skenes’ tendency to work deep into games. The Pirates’ Colin Holderman and David Bednar form a reliable late-inning tandem when given a lead. After yesterday’s emotional victory, the psychological edge definitely belongs to Pittsburgh’s relief corps.
Key Betting Trends & Team Statistics That Matter
- Pittsburgh is just 7-20 on the road this season but showed resilience with Tuesday’s comeback win
- The Pirates are 5-24 in games when they allow at least one home run
- Arizona is a mediocre 14-14 at home despite high preseason expectations
- The Diamondbacks are 3-7 in their last 10 games with a struggling 4.91 ERA during that stretch
- Pittsburgh has gone UNDER in 5 of their last 7 games when Skenes starts
- Bryan Reynolds is on fire for Pittsburgh, coming off a 4-hit performance in Tuesday’s win
- Arizona’s bullpen has blown 9 saves this season, tied for 3rd most in the National League
Bryan Reynolds: Pirates’ Hot Bat Against Arizona Pitching
Bryan Reynolds has been Pittsburgh’s offensive catalyst in this series, highlighted by his 4-hit performance on Tuesday that included a go-ahead three-run homer in the eighth inning. Reynolds is hitting .348 over his last 10 games and has historically performed well at Chase Field (.321 BA, 3 HR in 16 career games). His success against Zac Gallen (.375 in 16 at-bats with 2 doubles) makes him particularly dangerous in this matchup. With Reynolds seeing the ball so well and Gallen struggling with command, look for the Pirates’ outfielder to be a difference-maker again today.
Chase Field Factor: How the Venue Influences Today’s Game
Chase Field has played more neutral this season after the Diamondbacks installed a humidor several years ago, but it still slightly favors hitters with a park factor of 102 (league average is 100). The afternoon start time (3:40 pm ET) means temperatures inside the closed dome will be controlled, removing the extreme heat factor that can make the ball travel further in evening games when the roof is open. This controlled environment should benefit both pitchers, especially Skenes who thrives in neutral conditions where his high-velocity fastball and sharp breaking pitches can play up. One key factor: Chase Field’s dimensions are generous in the gaps, which could help limit Reynolds’ damage if Arizona can keep him in the park.
Expert Prediction & Best Bets for Pirates-Diamondbacks Showdown
Primary Play: Pittsburgh Pirates Moneyline (+217)
This price is simply too high given the pitching matchup. Skenes has been exceptional, and his ability to miss bats (9.2 K/9) should neutralize Arizona’s offense. Meanwhile, Gallen continues to struggle with his command and has been hit hard all season. When you’re getting better than 2:1 odds on the team with the superior starting pitcher, it’s a value I can’t pass up. The Pirates showed tremendous fight in yesterday’s comeback win, which could provide a confidence boost for a young team. I’d play this down to +190.
Strong Value Play: Under 8.5 Runs (-110)
With Skenes on the mound and Arizona’s offense hitting just .260 over their last 10 games, I like the under despite the half-run line movement. While Gallen has struggled, he’s still capable of quality outings, particularly when facing weaker offenses like Pittsburgh’s (3.09 runs per game, 29th in MLB). Both teams’ bullpens were taxed yesterday, which should lead to extended outings from both starters. I expect a low-scoring affair where Skenes’ dominance is the story of the day.
Worth Considering: Paul Skenes Over 7.5 Strikeouts (+115)
Arizona strikes out at a below-average rate (7.49 K/game), but Skenes’ elite stuff should generate plenty of swings and misses. He’s recorded 8+ strikeouts in 6 of his 11 starts this season, including three straight outings with 9+ Ks. At plus-money odds, this prop offers significant value for a pitcher who could easily reach double-digit strikeouts if he works deep into the game.
Player Props Worth Targeting in Today’s Matchup
| Player | Prop | Odds | Rating |
|---|---|---|---|
| Paul Skenes | Over 7.5 Strikeouts | +115 | ★★★★☆ |
| Bryan Reynolds | Over 1.5 Total Bases | +120 | ★★★★☆ |
| Corbin Carroll | Under 0.5 Runs Scored | -105 | ★★★☆☆ |
| Zac Gallen | Under 5.5 Strikeouts | -125 | ★★★☆☆ |
Final Thoughts: Underdog Value Too Good to Pass Up
Don’t be fooled by the overall records of these teams – this game comes down to the pitching matchup, and Paul Skenes gives Pittsburgh a legitimate chance to win outright. Arizona’s bullpen is compromised after yesterday’s collapse, and Gallen has not resembled the ace who finished fifth in Cy Young voting last season. The Pirates’ momentum from yesterday’s comeback win, coupled with Reynolds’ hot bat, makes them a live underdog. While I rarely recommend +200 underdogs, this line is significantly mispriced given the pitching disparity. Look for Skenes to deliver another gem and for Pittsburgh to claim the series.
Score Prediction: Pirates 4, Diamondbacks 2
