Angels’ business keeps booming with 9-3 win over Mariners

There are some triple-A lineups that feature a more experienced bottom of the order than the Nos. 7-9 hitters the Angels unveiled Saturday.

At 25, Mark Trumbo was the old-timer of the bunch. He was followed by Hank Conger, 23, and Mike Trout, the 19-year-old who might still get carded trying to get into R-rated movies.

The trio of rookies made a pair of big rallies in the Angels’ 9-3 victory over the Seattle Mariners at Angel Stadium look like child’s play, sparking outbursts that culminated in home runs by Torii Hunter.

Hunter crushed a three-run homer in the third inning and added a two-run, opposite-field shot in the fifth, finishing with a season-high five runs batted in. Not wanting to be left out of the power display, Trumbo hit his team-leading 16th homer leading off the eighth.

“He’s doing remarkably well for a guy in his first time around in the big leagues,” Angels Manager Mike Scioscia said of Trumbo, who is tied with the Washington Nationals’ Danny Espinosa for the rookie lead in home runs. “He’s showing his power, that’s for sure.”

The Angels have a youthful bounce in their step as the All-Star break nears, having won seven of eight games. They remained one game behind Texas in the American League West despite improving to a season-high seven games over .500.

The kids are all right and then some, having helped the Angels clinch eight consecutive series victories. That’s something they last did during a 100-victory season in 2008.

“These young guys, they’ve got some talent,” said Hunter, who homered in successive at-bats for the first time since April 2008. “I’m happy to have them up. They’re not scared at all.”

Trout recorded a handful of firsts in his second major league game: first hit, first walk and first runs scored.

His first hit traveled all of about 20 feet in the third inning, but it helped Trumbo score from second base. Trout did not have such noble ambitions. With runners on first and second and nobody out, he merely attempted a sacrifice bunt.

Seattle pitcher Michael Pineda sprinted off the mound to field the ball and made an errant throw past first baseman Adam Kennedy. Trumbo came home to give the Angels a 1-0 lead, prompting Trout to clap in approval.

“I’ll take it any way I can,” said Trout, who planned to put the ball in a special room in his New Jersey home.

One out later, Hunter blasted Pineda’s first pitch over the wall in left-center to make it 4-0 and delight a season-high crowd of 44,111.

After Angels starter Joel Pineiro (5-3) nearly gave back the entire cushion in the next two innings, yielding three runs, Trout and Hunter enabled the right-hander to breathe easier in the bottom of the fifth. Trout walked on four pitches with one out and scored on Maicer Izturis’ double to right-center, alertly coming home when center fielder Greg Halman momentarily bobbled the ball.

Hunter followed with his 11th home run, extending the Angels’ advantage to 7-3 and giving him a team-high 45 RBIs. He had only one home run in his previous 30 games.

Hunter’s power surge is part of a team-wide trend. After hitting only 14 homers in their first 34 home games, the Angels have 15 in their last 12 games at Angel Stadium.

“He’s certainly more comfortable in the box than he has been at any time this season,” Scioscia said of Hunter. “Hopefully, he’s going to keep going from there.”
