The Pirates head to Cincinnati getting slight plus money at -115 despite having the superior starting pitcher on paper. Bubba Chandler's 2025 numbers tell a much different story than Brandon Williamson's limited sample, and that's where the betting value emerges in this Great American Ball Park matchup.
Pittsburgh Pirates vs Cincinnati Reds MLB Betting Preview
The pitching matchup tilts this toward Pittsburgh despite the Pirates' rough 1-3 start to the season. Bubba Chandler brings a 4-1 record from last season with impressive control (just 4 walks in 31.1 innings) against Brandon Williamson, who managed only 14.1 innings in 2024 but allowed 4 home runs in that limited time. I looked at the run line here, but there's no credible path to multi-run separation with both offenses struggling early and the Reds playing at home. The moneyline at -115 offers fair value on the better starter, especially after Pittsburgh showed offensive life despite falling 4-3 to the Mets on Sunday.

The Pitching Matchup
Bubba Chandler posted a 4-1 record with a 4.02 ERA and 0.93 WHIP last season, but the peripherals paint a much sharper picture. His 8.90 K/9 rate shows swing-and-miss stuff, while allowing just 4 walks in 31.1 innings demonstrates advanced command for a young pitcher. That 0.93 WHIP is what catches my attention – it suggests he kept runners off base consistently. These 2025 numbers project well into 2026 for a pitcher entering his prime.
Brandon Williamson managed a 3.77 ERA in 14.1 innings back in 2024, but here's the problem: he surrendered 4 home runs in that tiny sample. At Great American Ball Park with its 1.10 park factor favoring hitters, that home run rate becomes concerning. His 7.53 K/9 is decent, but the 1.05 WHIP and home run tendency work against him facing a Pirates lineup that just scored 4 runs against the Mets despite losing.
The concern is sample size reliability – Williamson's 14.1 innings make any conclusions shaky. But Chandler's 31.1 innings provide a more trustworthy baseline for current season expectations. From an efficiency standpoint on the mound, Chandler's control gives him the edge against a Reds offense that showed extensive struggles last season, with JJ Bleday hitting .212 and Christian Encarnacion-Strand at .208. While these are 2025 numbers, the early season hasn't shown dramatic improvements from Cincinnati's core hitters.
The flip side of that is Cincinnati's early-season momentum – they've won 3 of 4 to start the year, including shutting out these same Pirates 2-0 just yesterday. The park factor matters here more than usual given Williamson's home run issues, but it works both ways if Pittsburgh can get to him early. That recent head-to-head loss actually creates sharper line movement against Pittsburgh than warranted.
Prediction
This looks like a close, low-scoring affair based on both teams' offensive struggles, but Chandler's superior command and strikeout ability should give Pittsburgh the edge. The Pirates broke their losing streak with offensive production in that 4-3 loss to New York, showing they can manufacture runs when needed. The risk is Pittsburgh's -7 run differential cutting into the edge, but at this price, the moneyline has value. I'm not buying the Reds at -105 after Williamson's home run issues in a hitter-friendly park, especially with yesterday's shutout creating false confidence in Cincinnati.
Projected Final Score: Pittsburgh Pirates 5, Cincinnati Reds 4
Best Bet: Pittsburgh Pirates Moneyline (-115)
