PITTSBURGH (AP) — Joe Mauer hit his first home run of the season, a solo shot off Antonio Bastardo in the 13th inning to help the Minnesota Twins to a 4-3 victory over the Pittsburgh Pirates on Wednesday night.

Mauer's fly ball to right reached the first row of seats, his first home run since Aug. 17, 2014. Torii Hunter went 3 for 5 with three RBIs for the Twins, who improved to an AL-best 13-5 in May.

Brian Duensing (2-0) picked up the win. Glen Perkins worked the last inning for his major league-leading 15th save.

Josh Harrison went 3 for 6 for the Pirates. Andrew McCutchen had three hits, including a solo home run off Blaine Boyer in the eighth but the Pirates fell to 0-6 in extra-inning games when Bastardo (0-1) let Mauer go deep.

Pittsburgh has lost six of seven and moved a season-worst four games under .500.
