PITTSBURGH — David Freese hit a grand slam off opener Michael Feliz and Cody Bellinger added his 18th homer, helping the Los Angeles Dodgers beat the Pittsburgh Pirates 10-2 on Friday night.

The Pirates gave Feliz his first major league start in 157 career appearances in an effort to address their injury-riddled starting rotation. The move backfired. Feliz recorded just one out and exited after Freese sent a pitch into the first row of seats in right-center field for his fourth homer of the season and third career grand slam.

Bellinger, whose 45-game on-base streak ended Wednesday, kick-started another one by hitting a two-run shot in seventh off Geoff Hartlieb. By then the Dodgers had things well in hand. Bellinger finished 1 for 5, and his major league-leading batting average dipped to .389.

Walker Buehler (5-1) cruised after being given the early cushion. Buehler worked six innings, allowing one run and five hits.

Kevin Newman had an RBI double for Pittsburgh. First baseman Josh Bell, who began the day leading the majors with 47 RBIs, went 1 for 4 but it wasn’t nearly enough for the Pirates.

Pittsburgh lost its seventh game by at least eight runs when Feliz — named the starter a few hours before first pitch as Pittsburgh scrambles to find answers for a rotation missing Jameson Taillon and Trevor Williams — failed to keep the Dodgers in check.
