Preview for Tuesday, September 15, 2026. Schedule and player information can change.

Milwaukee Brewers at Pittsburgh Pirates

The Brewers travel to Pittsburgh with Jacob Misiorowski on the mound, and his numbers stand out sharply against the rest of this matchup. Across roughly 161.3 innings, Misiorowski carries a 1.95 ERA and a 2.30 FIP, both of which are well ahead of anything else in this game. Pittsburgh counters with Lake Bachar, who has thrown about 79.3 innings with a 3.52 ERA and a 4.64 FIP, a solid but clearly less dominant line by comparison.

On the offensive side, Milwaukee's team wOBA sits at 0.326 compared to Pittsburgh's 0.319, giving the Brewers a slight edge at the plate. Milwaukee also holds an advantage in run prevention marks as a team, with a 3.79 FIP and 3.57 ERA against Pittsburgh's 3.94 FIP and 4.18 ERA, suggesting the Brewers have been the stronger overall pitching staff this season.

Both clubs have some injury situations to note. Grant Anderson and Braxton Ashcraft are each listed on the 15-Day IL for Milwaukee and Pittsburgh respectively, while J.B. Bukauskas and Sean Episcope are listed on the 60-Day IL for the Brewers. Pittsburgh also lists Kyler Fedko on the 7-Day IL and Jaiker Garcia on the 60-Day IL. Taken together, the team-level statistics and the individual pitching lines both favor Milwaukee, with Misiorowski's ERA and FIP figures standing as the most notable numbers in this matchup.
