Eric Hosmer and Salvador Perez helped the American League secure home-field advantage in the World Series by beating the National League 4-2 at the All-Star Game in San Diego.
The two Royals stars each blasted a home run in the second inning off San Francisco Giants starter and former team-mate Johnny Cueto.
They became just the second pair of team-mates to hit two home runs in the same inning since Steve Garvey and Jim Wynn of the Los Angeles Dodgers did it in 1975.
Hosmer received MVP honors after finishing the game 2 for 3 with a home run and two RBIs.
With the win, the AL has now won four All-Star games in a row. The NL has only scored eight runs during those four games.
After White Sox ace Chris Sale and Blue Jays youngster Aaron Sanchez gave up two runs in the first four innings, the AL's pitchers combined for five shutout innings with five strikeouts to end the game.
Cleveland Indians ace Corey Kluber earned the win after tossing a shutout second inning with one strikeout. Baltimore Orioles closer Zach Britton earned the save.
