ST. LOUIS — Erik Gonzalez and Adam Frazier singled in runs, rookie Cody Ponce earned his first big league victory and the Pittsburgh Pirates beat the St. Louis Cardinals 2-0 Thursday night for a doubleheader sweep.

Cole Tucker drove in the go-ahead run in extra innings in the Pirates’ 4-3 win in the opener.

Ponce (1-1) was used as a reliever in his first two appearances this season and made his first major league start. He went 5 2/3 innings, holding the Cardinals scoreless and scattering five hits.

Nick Turley pitched the seventh to record his first save in the majors. Prior to this year, Turley hadn’t appeared in affiliated ball since 2017 due to elbow injuries.

Pittsburgh scored both runs in the third. Gonzalez and Frazier hit back-to-back singles, scoring J.T. Riddle and John Ryan Murphy.

The seven-inning first game went to extras tied at one, and Tucker scored automatic runner Jarrod Dyson with a single off John Gant (0-2) in the eighth. Pittsburgh added two more runs with two outs on an RBI single by Bryan Reynolds and an error by third baseman Brad Miller.
