Angels rookie Mike Trout is selected to All-Star game

Add another chapter, with a star affixed, to Mike Trout’s exceptional rookie season with the Angels.

The 20-year-old outfielder was selected to the All-Star game in Kansas City on July 10, one of four Angels on the American League team.

The others are outfielder Mark Trumbo and starting pitchers Jered Weaver, who threw a no-hitter May 2, and C.J. Wilson.

Dodgers slugger Matt Kemp and pitcher Clayton Kershaw were selected for the National League team. But Kemp is on the disabled list because of a left hamstring strain.

“I don’t think I’m going to be able to play,” Kemp said. “I’m going to go and enjoy the festivities . . . but I’m going to get healthy and get ready for the second half.”

Kemp is the NL captain in the Home Run Derby on July 9 and plans to participate.

“It’s just like taking batting practice,” the center fielder said. “I’ve been doing that for the past three weeks, so I’m ready.”

Trout became the 20th player to be selected for the All-Star game before reaching his 21st birthday.

“It was kind of surreal; is this really happening to me?” Trout said in Toronto before he hit a home run to help the Angels defeat the Blue Jays, 10-6. Trumbo also hit a home run.

“It’s a dream come true after all the hard work,” said Trout, who began Sunday’s game tied for the AL hitting lead with a .336 average and leading the league in stolen bases with 22.

The starting eight position players were voted on by fans, and the reserves and pitchers were selected by the players and the managers, Ron Washington for the AL and Tony La Russa for the NL.

Weaver, who started last year’s game, said he would “just enjoy this opportunity. You never know if it’s going to be your last.”

Fans also will choose one of five players in each league who will be added as the “final player” to each team. The five AL candidates include Angels closer Ernesto Frieri.

Being a candidate was “huge for me already,” Frieri said. “If I get the chance to go, that would be amazing.”

The Texas Rangers and New York Yankees each have three AL starters, and the San Francisco Giants have three starters in the NL lineup.

The AL starters feature an outfield of Texas’ Josh Hamilton, Toronto’s Jose Bautista and New York’s Curtis Granderson, with an infield of Detroit’s Prince Fielder at first base, New York’s Robinson Cano at second base and Derek Jeter at shortstop, Texas’ Adrian Beltre at third base and Mike Napoli at catcher, and Boston’s David Ortiz at designated hitter.

The NL outfield starters are Kemp, San Francisco’s Melky Cabrera and St. Louis’ Carlos Beltran, with San Francisco’s Buster Posey at catcher and Pablo Sandoval at third base, Cincinnati’s Joey Votto at first base, Atlanta’s Dan Uggla at second base and St. Louis’ Rafael Furcal at shortstop. La Russa will select a designated hitter.

In making his second consecutive All-Star team, Kemp drew the third-highest number of fan votes among NL outfielders with 5.46 million.

Dodgers right fielder Andre Ethier, who is on the disabled list because of a sore rib-cage muscle, was not selected.

“It’s disappointing when you don’t get that nod to go,” said Ethier, who finished ninth in the voting for NL outfielders with 2.64 million votes. “I want to represent the Dodgers and represent the fans here.”

Hamilton received the most votes of any player in either league, a record 11.1 million.

Kemp tapped Beltran, Colorado’s Carlos Gonzalez and Miami’s Giancarlo Stanton for the NL Home Run Derby squad. All three were selected as reserves for the All-Star game.

The AL home run competitors will be announced Monday by Cano, their captain. Trumbo said he’s expected to receive an invitation.

Trumbo, 26, said he was “proud of the season I’ve put together [but] I still have a lot of work to do.”
