Pirates bat around in sixth to bash Red Sox

An eight-run onslaught across the fifth and sixth innings propelled the visiting Pittsburgh Pirates to a 10-3 win over the Boston Red Sox on Saturday.

All nine Pirates hit safely and three had two RBIs in support of Johan Oviedo (2-0), who allowed two runs on three hits and struck out six across five innings. Pittsburgh have won both games in the series and eight of its last 10 overall.

Jared Triolo and Spencer Horwitz (2-for-4) combined to score five runs, Bryan Reynolds and Nick Gonzales each had two-run hits and Oneil Cruz cracked his 19th home run.

Trevor Story and Romy Gonzalez each had two hits for Boston while Carlos Narvaez homered.

Pittsburgh began breaking the game open by scoring three runs in the fifth before recording an out.

Isiah Kiner-Falefa hit a leadoff infield single and, after Boston starter Dustin May (7-11) hit a batter and walked another, Reynolds stung a two-run single to right to give the Pirates a 3-2 lead. Pham's hit to left provided the inning's third run.

The visitors sent 10 to the plate to score five runs in the sixth, including Cruz depositing the second pitch of the frame into deep center for a solo homer.

A Joey Bart double and a walk two batters later ended the day for May, who gave up eight hits and seven runs (six earned) over 5 1/3 innings with four walks and five strikeouts. Horwitz greeted reliever Brennan Bernardino with a single to center that scored Bart, who kicked the ball away as he slid into home to allow Triolo to score as well.

After Bernardino walked two and struck out Andrew McCutchen, Gonzales snuck a two-out, two-run single up the middle to up Pittsburgh's lead to 9-2.

Boston got a run back as Gonzalez hit the third of three straight singles against reliever Mike Burrows in the sixth.

A McCutchen single and Gonzales double started Pittsburgh's ninth. Jordan Hicks' wild pitch allowed McCutchen to score the Pirates' 10th run.

The Pirates grabbed a 1-0 lead four batters into the game. They loaded the bases on an error, a Horwitz single and a Reynolds walk, which led to Tommy Pham's RBI groundout to third base.

After Oviedo stranded two Red Sox with nobody out in the second, Narvaez knotted the score when he lined a leadoff solo home run over the Green Monster to begin the third.

Story's leadoff double to begin the second went for naught, but he drew a leadoff walk and came around to score a run on Gonzalez's line-drive RBI single up the middle to give the Red Sox a 2-1 lead in the fourth.
