SAN DIEGO — Eric Hosmer stood in the middle of the field, holding up a trophy. He hopes to do it again with the Kansas City Royals this fall.

Hosmer and Salvador Perez homered off former Kansas City teammate Johnny Cueto during a six-pitch span in the second inning, Hosmer added an RBI single to become MVP of the All-Star Game and the American League beat the Nationals 4-2 Tuesday night for its fourth straight win.

If the defending champion Royals reach the World Series for the third straight year, they will start at home, sweet, home once again.

“Hopefully this is something we can all rally upon for the second half and find a way to use that home-field advantage,” Hosmer said.

David Ortiz found himself in the middle of the most touching moment at Petco Park, embraced by his AL teammates near first base after exiting his final All-Star Game. The popular Big Papi plans to retire at 40 after this season with Boston.

Kris Bryant of the Cubs led the parade of sparkling young talent with a first-inning home run. The Yankees’ Dellin Betances flashed his 100 mph heat, and Astros reliever Will Harris came on to throw a called third strike past Cardinals rookie Aledmys Diaz on a 3-2 pitch on the outside corner with the bases loaded to end the eighth.

Royals reliever Kelvin Herrera pitched a hitless sixth for the AL, which will open the Series at home for the 11th time in 14 years since the All-Star winner has been used to determine the hosts for Games 1 and 2.

Kansas City became baseball royalty last fall, bursting to a 2-0 lead over the New York Mets at Kauffman Stadium, where Cueto pitched a two-hitter in the second game. The Royals won in five games for their first title since 1985.
