Beckett and Wakefield, also 11-3, will represent the Red Sox along with closer Jonathan Papelbon, left fielder Jason Bay and Youkilis in the All-Star game Tuesday in St. Louis. AL starting second baseman Dustin Pedroia withdrew Sunday to be with his wife, who has had complications with her pregnancy.

The Red Sox won four of their last five games to improve to 54-34, their fifth-best record at the All-Star break since 1954. They’ve held at least a share of first place in the AL East since June 9. Kansas City lost for the fourth time in five games — including a 1-0 loss to Boston on Friday — and fell 14 games below .500.

Beckett allowed two runs or less for the ninth time in 11 starts and is 6-0 in nine home starts this year.

He began the game by striking out DeJesus and Maier and retiring Billy Butler on a fly to left. He started the second with two more strikeouts, against Teahen and Jose Guillen, then got Pena on an infield popup. In the third, he struck out John Buck.

After DeJesus doubled in the fourth, Maier sacrificed him to third but he was stranded. Beckett then retired all six batters in the fifth and sixth on 17 pitches.

He had his most trouble in the seventh when Maier led off with a single. Butler struck out, but Teahen singled Maier to third and Guillen was hit by a pitch, loading the bases. Beckett escaped the jam by getting Pena to ground to second baseman Pedroia, who started a double play.

Notes: Bay walked on his first three at bats on the minimum of 12 pitches then was hit by pitches on his other two at bats. ... Red Sox starters have allowed three runs or less in each of the last six games. ... Chen pitched in just his fourth game in the majors since undergoing elbow surgery in the Fall of 2007. ...

Francona said Clay Buchholz, having an outstanding season at Triple-A Pawtucket, will start Boston’s first game after the All-Star break, at Toronto.
