NEW YORK (AP) – Jason Giambi broke out of a 4-for-38 slump with a pair of home runs and drove in seven runs Sunday, leading the New York Yankees to a 10-3 victory and a sweep of their weekend series with the Kansas City Royals.

Giambi’s 22nd home run came in the third inning against loser Zack Greinke, following singles by Hideki Matsui and Alex Rodriguez. It gave Giambi 1,000 RBIs for his career.

Two innings later, he connected again for his 23rd homer and 1,500th career hit, this time after another hit by Rodriguez. It was the sixth multihomer game of the season for Giambi and the 29th of his career.

In the sixth, the Royals walked Rodriguez intentionally to load the bases, and Giambi followed with a two-run single to give him seven RBIs in a game for the third time in his career. Bernie Williams added a run-scoring single and drove in three runs.

Al Leiter (4-3) earned his third straight win, limiting the Royals to two hits in six innings. He struck out six, walked three and threw 112 pitches after reaching 75 after three innings.

Greinke (3-16) surrendered Giambi’s home runs and lost his fifth straight decision.

The Yankees jumped in front in the first inning when they loaded the bases on walks to Matsui and Giambi sandwiched around a single by Gary Sheffield. Williams then bounced a two-out, two-strike single into right field, scoring Matsui and Sheffield.

The Royals picked up a run in the third but could have had more after Denny Hocking opened with a walk and Joe McEwing doubled. After David DeJesus’ run-scoring groundout, Leiter walked Chip Ambres and Mike Sweeney to load the bases.

Leiter recovered to get Emil Brown and Terrence Long, ending the inning. He then retired nine of the next 10 batters.

Sweeney hit his 19th homer, a two-run shot in the eighth.

Notes: Attendance was 54,951, the 38th sellout in 68 home dates for the Yankees. … Williams’ three RBIs gave him 20 in the last 16 games. … Leiter struck out the side in the second inning. … Greinke’s last win was July 19 at Cleveland. … Derek Jeter had three hits. … Robinson Cano made a baserunning blunder in the second when he walked off second base, thinking he had been called out on an attempted force play, and then was thrown out to complete an odd double play.
