CHICAGO (AP) — Rookie Jack Suwinski, who attended high school 20 minutes from Wrigley Field, hit a tiebreaking home run and the Pittsburgh Pirates beat the Cubs 3-2 Wednesday night, ending Chicago’s four-game winning streak.

Suwinski made his major league debut this season and began the day hitting .183 with two homers.

With the score 2-all, the 23-year-old outfielder from Taft High School opened the fifth inning with a drive off Drew Smyly (1-5) that barely cleared the center field wall.

Michael Chavis’ single in the third snapped the Pirates’ scoreless streak of 20 innings. They scored in the eighth inning of Sunday’s 1-0 win over the Reds despite being no-hit by Hunter Greene and Art Warren, then lost 9-0 and 7-0 earlier this week at Wrigley Field.

Pirates relievers Mitch Keller, Duane Underwood Jr. and David Bednar allowed four hits over the final seven innings. Wil Crowe went two innings in his first start of the season after 13 relief appearances.

Underwood and Bednar combined to retire 13 of the final 15 batters they faced. Bednar pitched the final two innings to earn his eighth save in as many chances to preserve the win for Keller (1-5).

Smyly struck out a season-high five in the first two innings, but the Pirates solved him quickly the second time through the order.

Ke’Bryan Hayes snapped an 0-for-12 slump with a double that hit the top of the net in center field before caroming into play. Chavis hit an RBI single past a diving Jonathan Villar at second, and Daniel Vogelbach beat the shift with a single through a large hole between second and third to cap a two-run third.

Ian Happ’s homer in the first off Crowe staked the Cubs to an early lead. Happ is batting .345 (29 for 84) with six doubles and four homers in his last 25 games against the Pirates.

Frank Schwindel hit a tying single in the Cubs fourth but was caught wandering off second base too far after Villar’s subsequent single to left.
