A stalwart of the Rays teams that changed the franchise from perennial loser to 2008 American League champions and postseason regulars, Shields allowed just three hits in seven innings with 10 strikeouts, a walk and a hit batter. Shields (9-4) won for a record 48th time at Tropicana Field.
Tampa Bay began to resemble its Shields-era self with a 9-2 road trip that rekindled hopes of midseason recovery, but it dropped the opener of a six-game homestand. Kansas City outhit the Rays 14-4.
Rays right-hander Jake Odorizzi (4-8) allowed two runs on six hits and two walks with eight strikeouts in six innings.
Alex Gordon and Omar Infante each collected three hits for Kansas City.
Orioles 8, Nationals 2 (11 innings)

In six innings, Green gave up two runs on four hits with two strikeouts and no walks.
White Sox 4, Red Sox 0
BOSTON -- Rookie right-hander Scott Carroll, making his eighth major league start, became the latest pitcher to handle last-place Boston. He gave up one hit over 6 2/3 innings, and two relievers finished off a two-hitter as Chicago cruised in the opener of a four-game series.
Adam Dunn and Dayan Viciedo homered against Clay Buchholz, Dunn's 13th of the season a solo shot in the second inning and Viciedo's 11th a three-run job in the fourth.

First baseman Anthony Rizzo hit a two-run home run and left fielder Chris Coghlan went 4-for-5 with two doubles for Chicago, which went 2-for-15 with runners in scoring position and left nine on base.
Bruce, playing first in place of injured Joey Votto, made a couple nice fielding plays but also committed an error that led to a run.
Mets 4, Braves 3 (11 innings)
NEW YORK -- Ruben Tejada's two-out, RBI single in the bottom of the 11th gave New York a win over Atlanta at Citi Field.
