Halos matching Buckner against Royals

KANSAS CITY -- The Angels will likely start right-hander Billy Buckner on Saturday against the Royals.

Buckner would be the 21st pitcher used by the Angels this year. The club record for pitchers used in a season is 29.

"That's the direction, hopefully, that we'll be able to go," manager Mike Scioscia said. "He'll go as long and as hard as he can. I think he'll be fine."

Buckner was recalled from Triple-A Salt Lake on May 16. He made eight starts this season with the Bees, posting a 4-2 record with a 4.56 ERA.

Buckner will face the team that drafted him. Kansas City was Buckner's first stop in the Major Leagues and he got his first big league win with the Royals in 2007.

Trout showcases power, speed against KC

KANSAS CITY -- The Kauffman Stadium press box announcement on Mike Trout's first-inning homer to straightaway center on Thursday night was that the blast traveled an estimated 433 feet. Another estimate had the drive at 463 feet, but even that seemed tight to Angels manager Mike Scioscia.

"It had to be between 480 and 500 feet," Scioscia said. "With the naked eye looking at it, it's got to be 500 feet. "

Trout's monster drive, which was interrupted by a backdrop wall, came off a fastball from Royals starter Ervin Santana.

"You've got to get back down to the level of the plate," Scioscia said. "That thing hit still probably 30 feet above the ground. There's a way to figure it out, but calculus was out of my league."

Trout's rare blend of power and speed was reinforced in the eighth inning, when he stole second with the Angels up by one.

It marked the fourth time this year that Trout had homered and stolen a base in the same game, which led the American League entering Friday's contest. Since 2012, Trout has 11 games with a homer and a steal in the same game and that leads the Majors over that span.

"That is a select club," Scioscia said. "That's what makes Mike's talents so incredible. No only in the game today, but that's a select group in any year in baseball."

Trout came up with his 11th steal in the seventh inning in Friday's 5-2 win over the Royals on a disputed call at second base. He also had his fourth consecutive multihit game, which matched a career high.

Weaver moving forward after BP session

KANSAS CITY -- Right-hander Jered Weaver had another positive day on Friday as he puts the finishing touches on his rehabilitation work before rejoining the Angels' rotation.

Weaver threw a light bullpen session at Kauffman Stadium and will have another bullpen session this weekend before any activation decision is made.

"He feels good," manager Mike Scioscia said. "Hopefully, he'll keep progressing and we'll probably have a decision on him in a couple of days."

Weaver has been on the 15-day disabled list since April 8 because of a fractured left elbow. He worked 5 2/3 innings in an extended spring game on Wednesday and threw 75 pitches.
