SAN DIEGO (AP) -- Eric Hosmer hit a historic shot that made San Diego the first team in the majors to launch grand slams in four straight games, and the Padres needed an unearned run in the 10th inning for a wild, 8-7 win over the Texas Rangers.
The Padres swept the four-game, home-and-home series, with a slam in each one. Hosmer's go-ahead shot against Kyle Gibson with one out in the fifth inning bounced off the top of the right field wall and into the seats for a 5-2 lead.
Earlier this week, Fernando Tatis Jr., Manny Machado and Wil Myers slammed the Rangers.
The Padres' 5-2 lead would not last, as reliever Michel Baez gave up a three-run double to Danny Santana in the top of the 7th. Texas grabbed a 6-5 lead one inning later on a Jose Trevino RBI single.
San Diego regained the lead in the bottom of the eighth inning, thanks to back-to-back homers from Ty France and Austin Hedges.
Emilio Pagan was sent in to close the game in the top of the ninth, but Nick Solak tied the score at 7-7 with a solo shot to right center.
The game went to the 10th inning, and after the Rangers were unable to score in the top half of the frame, Jake Cronenworth's single to center slipped past the glove of outfielder Scott Heineman, allowing Myers to score from second base for the victory.
