Mets vs Pirates Picks: Is the Under 8.5 the Smart Play?

by | Jun 27, 2025 | mlb

Mitch Keller Starting Pitcher Pirates

The New York Mets (48-34) head to PNC Park to take on the Pittsburgh Pirates (32-50) in what sets up as a fascinating pitching matchup between David Peterson and the struggling Mitch Keller. While their records couldn’t be more different, Keller’s peripheral statistics suggest he’s been far better than his 1-10 record indicates. With the Mets looking to build momentum after taking two of their last three from Atlanta, and Peterson continuing his stellar season, I’m expecting a competitive, low-scoring affair where value can be found in several markets.

Quick Picks:

  • Best Bet: Under 8.5 Runs (-110) ★★★★☆
  • Top Prop: David Peterson Over 5.5 Strikeouts (-120) ★★★★☆
  • Value Play: Mets -1.5 Runs (+125) ★★★☆☆

Sharp Money Analysis: Where Pro Bettors Are Placing Their Wagers

Professional money has been steadily supporting the Mets since this line opened, pushing it from -155 to -161 despite some moderate pushback. What’s more interesting is the lack of movement on the total, which has stayed firm at 8.5 despite PNC Park traditionally playing as a pitcher-friendly venue (1.054 run factor) and both starters showing decent form recently. This resistance to movement suggests sharp bettors see value in the under, aligning with my own analysis of this pitching matchup.

Pitching Matchup: David Peterson vs Mitch Keller – Who Has the Edge?

New York Mets: David Peterson (5-3, 2.98 ERA)

  • One of the Mets’ most consistent starters with a sparkling 2.98 ERA over 90.2 innings
  • Excellent 78:31 strikeout-to-walk ratio demonstrating his command
  • Has gone at least 6 innings in 9 of his 15 starts this season
  • Lefty has been particularly effective against right-handed heavy lineups

Pittsburgh Pirates: Mitch Keller (1-10, 4.02 ERA)

  • Record is highly deceiving – his 4.02 ERA and 1.22 WHIP suggest much better performance
  • Solid 73:24 K:BB ratio over 94 innings shows his command remains intact
  • Has received the lowest run support in the National League (2.14 runs per start)
  • Nine quality starts this season have resulted in just one win

Advantage: Mets, but closer than their records suggest. Peterson has been excellent, but Keller’s advanced metrics indicate he’s been a victim of poor run support rather than poor pitching.

Bullpen Breakdown

The Mets hold a significant edge in the bullpen department. New York’s relief corps ranks among the top five in baseball with a 3.22 ERA, anchored by closer Edwin Diaz who has converted 16 of 17 save opportunities. Reed Garrett has emerged as an elite setup option with a 2.05 ERA and 14 holds. Meanwhile, Pittsburgh’s bullpen has been inconsistent at best, posting a 4.33 ERA over the last month. David Bednar has stabilized after his early-season struggles (2.93 ERA with 11 saves), but bridge relievers like Dennis Santana and Caleb Ferguson have been overworked recently, throwing a combined 8.1 innings in the past four games.

Key Betting Trends & Team Statistics That Matter

  • The Mets are 19-22 on the road this season but have won 6 of their last 9 away games
  • Pittsburgh is surprisingly competitive at PNC Park with a 20-21 home record despite their overall struggles
  • The Pirates are 3-7 in their last 10 games overall, being outscored by 15 runs
  • New York has also gone 3-7 in their last 10 games, with their pitching staff struggling (5.01 ERA)
  • The under is 7-3 in Keller’s last 10 starts, largely due to Pittsburgh’s anemic offense
  • Peterson has allowed two earned runs or fewer in 8 of his last 10 starts
  • The teams have faced each other three times this season with the Mets winning two

Juan Soto’s Meteoric Rise: How the Star RF Has Transformed the Mets

Juan Soto has silenced any early concerns about his adjustment to New York, emerging as the offensive catalyst the Mets hoped for when they signed him. Leading the team with 19 home runs and an .899 OPS, Soto has been particularly hot over the past month. What makes him especially dangerous is his plate discipline – his league-high 66 walks have contributed to a .428 on-base percentage that ranks among MLB’s best. Against Keller, Soto has historically performed well, going 4-for-11 with two doubles in their previous matchups. His ability to work counts and punish mistakes will be crucial against a pitcher who has been better than his record indicates.

PNC Park Factor: How the Venue Influences Today’s Game

PNC Park has historically been pitcher-friendly (1.054 run factor), but tends to suppress home runs significantly (0.893 HR factor). The spacious left field and deep left-center gap particularly reward right-handed power hitters who can drive the ball to the opposite field. Tonight’s forecast calls for comfortable temperatures around 75°F with minimal wind, which should maintain the park’s typical characteristics. Peterson’s ground-ball tendencies (52.3% ground ball rate) align perfectly with PNC’s dimensions, while Keller’s ability to keep the ball in the park (0.86 HR/9) plays well in his home stadium. These factors contribute significantly to my projection of a lower-scoring game than the market suggests.

Expert Prediction & Best Bets for Mets-Pirates Showdown

Primary Play: Under 8.5 Runs (-110)

This total is set too high considering the pitching matchup and venue. Peterson has been one of the most consistent starters in the National League with his 2.98 ERA, while Keller’s 4.02 ERA understates how effective he’s been. PNC Park’s homer-suppressing tendencies (0.893 HR factor) further bolster the case for the under. Both teams have struggled offensively recently, with each batting just .231 over their last 10 games. I see tremendous value in the under and would play it down to 8 runs.

Strong Value Play: David Peterson Over 5.5 Strikeouts (-120)

Peterson has recorded 6+ strikeouts in seven of his last nine starts, and faces a Pirates lineup that ranks fourth in MLB in strikeouts (8.79 K/game). Pittsburgh’s right-handed heavy lineup plays into Peterson’s strengths, as his slider has generated a 34% whiff rate against right-handed batters this season. With the Pirates likely to stack righties against the southpaw, Peterson should have multiple opportunities to rack up punchouts. I’d play this up to -135.

Worth Considering: Mets -1.5 Runs (+125)

While I’m projecting a lower-scoring game, the run line offers substantial value at +125. The Mets have superior pitching and a more potent offense, and have won by multiple runs in 29 of their 48 victories this season (60%). Against a Pirates team that’s been outscored by 15 runs over their last 10 games, the Mets should be able to create enough separation to cover the run line.

Player Props Worth Targeting in Today’s Matchup

Player Prop Odds Rating
David Peterson Over 5.5 Strikeouts -120 ★★★★☆
Juan Soto Over 1.5 Total Bases +110 ★★★★☆
Mitch Keller Over 5.5 Strikeouts +105 ★★★☆☆
Pete Alonso To Hit a Home Run +310 ★★★☆☆
Oneil Cruz Under 0.5 Runs Scored -130 ★★★☆☆

Final Thoughts: Betting Value Lies in Pitching Strengths

This matchup presents a classic case where surface-level statistics (particularly Keller’s 1-10 record) create market inefficiencies. Both pitchers have performed better than most casual bettors realize, and PNC Park’s dimensions further support a pitching-dominant contest. The total of 8.5 runs simply doesn’t account for Peterson’s consistency, Keller’s bad luck, and both teams’ recent offensive struggles. While the Mets are deservedly favored, the most obvious value lies in the under and Peterson’s strikeout potential against a whiff-prone Pirates lineup.
