What’s Happening

The St. Louis Cardinals and Pittsburgh Pirates are set to open a critical four-game series on Monday, April 27, 2026, at PNC Park, with the Cardinals desperately seeking to halt a three-game losing streak. St. Louis was swept at home by an unnamed opponent, losing all three games by a combined margin of just four runs, a fact that has left manager Oliver Marmol searching for positives. "It sucks that you don't win one of these, but when you look at each game individually, there are a lot of positives," Marmol said. The Cardinals will hand the ball to right-hander Dustin May for the series opener, hoping his career strikeout-to-walk ratio of 4.57 against the Pirates can stabilize a rotation that has struggled to close out tight contests.

The Pirates enter the series with momentum, having won two straight games against the Milwaukee Brewers, including a 6-3 victory in extra innings on April 25 and a 6-0 shutout on April 24. Pittsburgh currently sits at 16-11, third in the NL Central, while the Cardinals have yet to report their record but are clearly in a downturn. The Pirates' pitching staff has been effective, posting a collective 3.30 ERA and a 1.24 WHIP over the season's first month, though they will be without starter Jared Jones, who is on the 60-day injured list until at least May 25. The St. Louis Cardinals vs. Pittsburgh Pirates matchup will test whether Pittsburgh can maintain its early-season form against a desperate division rival. [ESPN, Sun 26]

Looking ahead, the Cardinals have already announced that right-hander Hunter Dobbins, a former pitching prospect acquired from the Boston Red Sox in the Willson Contreras trade, will make a spot start on Thursday to close out the series. Dobbins currently carries a 4.13 ERA and will be making his first start for St. Louis, adding an element of uncertainty to the rotation. Meanwhile, catcher Pedro Pages will return to the lineup on Monday after a brief absence, though he is expected to share catching duties with Ivan Herrera. The outcome of this St. Louis Cardinals vs. Pittsburgh Pirates series could have significant implications for the NL Central standings, as both teams look to gain ground early in the season.
