KANSAS CITY, Mo. (AP) – Curt Schilling gave up nine doubles and a homer, and the Kansas City Royals rallied for three runs in the eighth inning to beat the Boston Red Sox 5-4 Thursday night for a surprising three-game sweep.

Reggie Sanders doubled three times as the Royals, with the worst record in the majors, sent the Red Sox to their first five-game losing streak since 2004.

Boston began the day a season-high three games behind New York in the AL East.

Schilling (14-5) led 4-2 going into the eighth but failed to become the majors’ first 15-game winner.

Mike Sweeney and Mark Teahen hit consecutive doubles to make it 4-3. Emil Brown walked and Sanders tied it with his double.

Ryan Shealy’s infield single, the only hit by the Royals that did not go for extra bases, pushed across the go-ahead run and finished Schilling.

Andrew Sisco (1-2) got the win with one inning of relief. Ambiorix Burgos got his 18th save in 28 chances.

Wily Mo Pena hit a three-run homer in the seventh for a 4-2 Boston lead. Kevin Youkilis doubled leading off, Mike Lowell singled and Pena hit a 429-foot home run off Runelvys Hernandez’s 0-2 pitch.

Doug Mirabelli, in his first at-bat since missing four games with an ankle injury, homered leading off the third for a 1-0 lead for the Red Sox.

Manny Ramirez singled his first two at-bats and extended his career-best hitting streak to 25 games, second only to Chase Utley’s 35-gamer in the majors this year. He is hitting .402 during the streak.

Mark Grudzielanek made a highlight reel play on Alex Cora’s soft fly into right-center in the fifth. Stretching with his back to the infield, Grudzielanek got the ball in his glove, but then it popped out into the air.

While doing a hard bellyflop onto the turf, the second baseman grabbed it with his bare hand and held on.

Notes: Schilling set a major league record by going his 54th straight start without giving up an unearned run. Schilling also set the mark by going 53 in a row with Arizona over 2001-02. This current streak began after he gave up two unearned runs on June 14, 2004 at Colorado. … A large and unusually beautiful rainbow northeast of the stadium had fans gawking in the fourth. … The Red Sox have had a losing year in Kansas City for the second season in a row. They had gone 6-0-1 the previous seven campaigns. … The start of the game was briefly delayed by rain.
