ANAHEIM, Calif. - The Los Angeles Angels came up with just enough offense to overcome one of John Lackey’s worst outings of the season and a subpar outing by their bullpen.

Jeff Mathis had four hits with a career-high six RBIs, including his first grand slam in the majors, and Casey Kotchman had a career-best five hits for the AL West leaders in a 14-11 victory over the Cleveland Indians on Wednesday.

“Everybody came out swinging today and we were making solid contact,” said Howie Kendrick, who had four hits and drove in three runs. “It seemed like we had runners in scoring position all day. We were getting pitches out over the plate to hit, and guys weren’t missing. Our pitchers have been carrying us for a while, but it looks like our bats are waking up a little bit.”

The Angels padded their AL West lead to 10 games over Oakland with a season-high 19-hit attack. Kendrick equaled a franchise record with three doubles and raised his average to .341.

“Right now I’m just feeling good and trying to ride it out,” said the Angels’ second baseman, who returned to the lineup on May 30 after missing 42 games with a strained left hamstring.

“When you’re coming back off an injury, you’ve just got to see pitches and get that confidence back. I’m feeling very good in the box right now, I’m seeing the ball pretty well and I think I’m being a little more patient. And whenever you do that, guys have to throw you strikes. So you’ll get pitches to hit.”

It was the first time in Angels history that three players each had four or more hits in the same game. Mathis added a two-run double in the sixth and Kendrick capped the Angels’ scoring binge with a two-run single in the seventh.

“Nobody had been really hot yet for us, so you figured it was just a matter of time until things clicked,” said Gary Matthews Jr., who had two RBIs. “Our pitching has been so good this year, and now we’re finally starting to swing the bats the way we’re capable of.”

Kotchman, the son of longtime Angels scout and minor league manager Tom Kotchman, raised his average to .289. He is third on the club with 48 RBIs and leads the Angels with 24 doubles.

“Kotch has been great for us all year,” Lackey said. “He’s a smart hitter and he’s been around the game forever because of his dad, so he really understands situations. And I think that helps him a lot.”

Lackey (8-2) allowed six runs and eight hits over five innings, but was able to call it quits with a 10-6 lead after his teammates scored five runs in the fifth. The six runs were the most allowed by the right-hander in any of his 77 career victories.

Lackey is 2-1 with a 7.60 ERA in his last four starts, after allowing no more than two earned runs in eight of his previous nine outings this season. He threw 32 of his 99 pitches during Cleveland’s two-run first.

“He obviously didn’t have his best stuff today, but he kept battling through it,” Mathis said of his batterymate. “He got through five today, and luckily we were able to put some runs on the board for him. It’s always nice when you can help your pitcher out.”

Somehow out of all this chaos, Francisco Rodriguez ended up with his major league-leading 42nd save after Jose Arredondo gave up a two-out RBI double in the ninth to David Dellucci.

“We fought hard, we just didn’t win,” Cleveland’s Grady Sizemore said. “It’s not a wasted effort, but it’s still not what we wanted as far as the outcome.”

Aaron Laffey (5-7) pitched four-plus innings, allowing eight runs and 12 hits. The Indians had a 6-5 lead when the left-hander departed with the bases loaded and none out in the fifth.
