Salvador Perez hit his first career grand slam, connecting in the eighth inning to rally the Kansas City Royals over the Boston Red Sox 6-4 Wednesday.
The Royals have won nine of 11 and moved within a game of .500.
Perez homered over the Kansas City bullpen in left field on the ninth pitch from Robby Scott (0-1). With Boston leading 4-2, reliever Matt Barnes started the inning by walking Jorge Bonifacio and Lorenzo Cain on 12 pitches.
Scott was summoned to face Eric Hosmer, but walked him on four pitches to load the bases for Perez. The All-Star catcher fouled off three full-count deliveries before hitting his 15th home run of the season.
According to ESPN Stats and Information, Perez was the first Kansas City player to hit a grand slam in the eighth inning or later with the Royals trailing since Frank White in 1986.
Jorge Soria (3-2) worked a spotless eighth. Kelvin Herrera pitched the ninth for his 17th save in 19 chances.
