Pittsburgh Pirates vs San Francisco Giants Prediction, Odds and Picks for Today, 05/10/26

I favor the Pittsburgh Pirates over the San Francisco Giants on Sunday. For starters, I believe the Pirates are the better team with the more realistic postseason outlook in 2026. Secondly, their offense is in far better form against right-handed pitching, ranking 7th in wOBA compared to the Giants — who rank dead last. Lastly, Pittsburgh’s pitching situation is more enticing with a pitcher-friendly park to mask their starter’s biggest concern, and all 3 of their high-leverage relief options off consecutive days of rest.

Bubba Chandler has been the weakest part of the Pirates starting rotation in 2026. They are just 2-5 in his starts, as the right-hander has posted a 4.76 ERA through his 34 innings of work. His 5.12 xERA is not an encouraging mark, but this matchup is the best get-right spot in the sport right now. The Giants offense is as anemic as there is currently, and this park is designed to keep the ball in the park. 

Tyler Mahle has a 5.00 ERA and 4.67 xERA in his first 36 innings this season. Like Chandler, Mahle has been issuing too many free passes, and Pittsburgh has been a very patient lineup. Pittsburgh averages the 8th-most pitches per plate appearance as a team, and they have the 5th-highest walk rate against right-handed pitching. That combined with Mahle’s 19th-percentile whiff rate, and I expect another strong offensive outing from this Pirates lineup.
