Royals swept in Boston

BOSTON — Jon Lester just wants to put up impressive numbers on the mound. He will worry about the figures on his next contract later.

Red Sox fans showed appreciation for his latest brilliant outing with loud applause as he walked to the dugout after his eighth and final inning Sunday.

Lester, who can become a free agent after the season, allowed no earned runs for the third time in four starts. He struck out eight and gave up two walks and four hits. Only one Royals player reached third base.

Lester (10-7) is 4-0 with a 0.85 ERA over his last seven starts with 47 strikeouts and eight walks in a span of 52 2/3 innings. He has yielded just one earned run in 31 innings.

Kansas City went scoreless after losing 2-1 Saturday night. The Royals have lost nine of 12, are 9-17 since a 10-game winning streak, and have scored less than two runs in four of their last six games. They open a three-game series at the Chicago White Sox on Monday night.
