Pittsburgh Pirates left-handed starting pitcher Andrew Heaney and the offense both dominated the St. Louis Cardinals in a 7-0 shutout victory at PNC Park in the series opener. The Pirates tie their season-best winning streak of four games, as they swept the New York Mets over the weekend, also at PNC Park. Pittsburgh improves to 36-50 overall and 24-21 at home, while St. Louis falls to 47-39 overall and 21-22 on the road. First baseman Spencer Horwitz led off for the Pirates in the bottom of the first inning, his first time doing so in 2025 and for the franchise.
