Giants vs Pirates Prediction

Pittsburgh comes into this contest after avoiding a sweep on Sunday afternoon and they have won six of their last eight games. The Pirates are 31-25 at home this season, while the Giants are 28-30 on the road. San Francisco did just win two out of three against the Mets, but they have struggled over the last few weeks. The Giants are starting Verlander, who has allowed a total of one earned run in his last 10.0 innings. The Pirates are going with Oviedo, who hasn’t pitched in the MLB since 2023 due to injury. I really don’t love how San Francisco is playing, but Verlander has shown improvement and we have to fade Oviedo here. Take the Giants to win.
