KANSAS CITY, Mo. -- Billy Buckner continued the string of strong starting pitching for the Los Angeles Angels, who beat the Kansas City Royals, 7-0, on Saturday and increased their winning streak to seven games.
The Angels' rotation has a 1.76 earned run average during the streak.
Josh Hamilton and Hank Conger hit solo home runs and Mike Trout scored twice, the fifth straight game he has scored two runs.
Buckner, who had not pitched in the big leagues since 2010 with Arizona, limited the Royals to two hits over five scoreless innings.
A 2004 second-round pick of the Royals out of South Carolina, Buckner had not pitched since May 11 for Class AAA Salt Lake.
Buckner became the 10th starting pitcher used by the Angels in 49 games after they utilized only eight last season.
Conger hit his second home run of the season to lead off the sixth inning, the first hit off Jeremy Guthrie (5-3), who took the loss. Hamilton hit his seventh home run in the seventh.
The Angels put the game away with a four-run eighth to chase Guthrie. The inning included Mark Trumbo's two-run single. Trout and Howie Kendrick contributed RBI singles.
After starting the season 5-0, Guthrie has lost his last three starts. He gave up seven runs, six earned, on five hits, two hit batters and a walk in 7 1/3 innings.
Trout scored the first Angels' run in the fourth, when he walked, stole second and went to third on a throwing error by George Kottaras and scored on a grounder by Albert Pujols.
The Royals grounded into two double plays and went 0-for-5 with runners in scoring position.
Royals second baseman Chris Getz was ejected in the sixth inning by first base umpire Mike Everitt after he thought he was safe when he grounded into a double play.
The Royals have lost 15-of-19 games to tumble to a season-worst four-games below .500. The Royals were shut out for the third time this season.
NOTES: The Angels are optimistic that RHP Jered Weaver, who has missed 43 games because of a broken left arm, will be able to pitch Thursday against the Dodgers or in the weekend series against Houston. ... RHP Kevin Jepsen, who is on the disabled list because of a strained right shoulder, pitched a scoreless inning Friday on a minor league rehab assignment with Class AAA Salt Lake and the Angels could activate him this week. ... Royals pitching coach Dave Eiland was in Florida to attend his daughter's confirmation and will return Monday. Bullpen coach Doug Henry is filling in for Eiland. Minor league pitching coordinator Steve Foster, who was the bullpen coach the last two years, will serve as the bullpen coach for the final two games of the Angels series. ... C Salvador Perez, who missed two games in Houston during the week because of a deep right hip bruise, was not in the Royals lineup Saturday, a day game after a night game.
