Phillies vs. Diamondbacks Prediction, Picks & Odds: NLCS Game 4
The Arizona Diamondbacks can pull even with the Philadelphia Phillies at two games apiece with a second straight win Friday after recording a walk-off win Thursday and we have our best Astros vs. Rangers predictions for the NLCS Game 4 based on the best MLB odds.
The Philadelphia Phillies trailed for only two innings throughout the postseason entering Game 3 and did not trail Thursday until the final at-bat of a 2-1 loss. Diamondbacks second baseman Ketel Marte had batted .289 with three home runs and 75 RBIs in 83 career at-bats with the bases loaded before his walk-off single yesterday. Marte joined Luis Gonzalez (2001 WS Game 7) and Tony Womack (2001 NLDS Game 5) as the only Diamondbacks hitters with walk-off postseason hits.
Arizona improved to 17-7 at home since August 12 (including the postseason), which is the best in MLB.
Here is our best Phillies vs. Diamondbacks prediction for Game 4 of the NLCS (odds via our best MLB betting sites; pick confidence based on a 1-to-5-star scale).
Phillies vs. Diamondbacks prediction: NLCS Game 4
Under 9.5 (-105 via Caesars) ⭐⭐⭐
The Phillies came into Game 3 with a +15 home run differential in the postseason, which was on pace for the record. In addition, they had been slugging .575 as a team, the highest in postseason history to this point. However, all it took to silence Philadelphia’s bats, primarily responsible for the best run differential in MLB postseason history through eight games (+33), was a heroic effort from Diamondbacks starting pitcher Brandon Pfaadt and a change of scenery.
Pfaadt became the second Diamondbacks pitcher in postseason history (joining Randy Johnson) with six-plus strikeouts in the first three innings, and he finished with a career-high nine strikeouts. When Pfaadt was not busy striking Phillies out, he often escaped with loud outs as several warning-track balls were likely a product of Chase Field’s home run suppression (-5% HR rate per BallPark Pal).
Arizona still being alive while down 2-1 in the series is astonishing, given its 3-for-15 batting with runners in scoring position and one stolen base despite finishing second in the regular season in that category.
The pitching matchup suggests runs should be scored, as Philadelphia’s Cristopher Sanchez is making his first postseason start, while Arizona’s Joe Mantiply opens a bullpen game. However, Sanchez finished the regular season with a career-low 3.44 ERA and career-high in strikeouts (96), and he should be able to at least get through the batting order at least one time unscathed, given that he ranks in the 95th percentile or better in ground ball percentage, chase percentage, and walk rate. Yesterday’s starter, Ranger Suarez, lowered the ERA of a rotation that had pitched to a 1.55 ERA with a 51:4 K:BB ratio in the first eight games of the postseason, and Sanchez has a great chance to improve those numbers.
Entering Game 2, Mantiply held left-handed batters to a combined .185/.209/.231 slash line, which will come in handy when facing Kyle Schwarber and Bryce Harper in the top of the first inning. Arizona held Philadelphia scoreless Thursday over the first four innings, the only four-inning span where the Phillies had not scored a run in the postseason.
We are only making the Under a three-star play out of respect for how the ball did not seem to carry well at Chase Field. This would be a more confident play if we were not skeptical that regression could come for a Phillies bullpen who entered Game 3 with a high 4.61 xFIP relative to its low 1.09 ERA.

Caesars is our go-to shop as Under backers, especially given that three of our best sports betting apps are juiced to the Over. Given the $10 disparity between Caesars’ -105 odds and BetMGM’s and bet365’s -115 odds, it will be interesting to see which way the line moves if it ever moves off the 9.5-run total.
This is only a play at 9.5 or above and would be a no-play no matter the price if it dropped to 9.0 runs.
