KANSAS CITY, Mo. -- Jarrod Dyson went 3-for-3 and drove in the winning run with two out in the eighth as the Kansas City Royals rallied to defeat the Oakland Athletics, 4-3, on Saturday.
Dyson's infield single with the bases loaded scored Alcides Escobar, who was running for Miguel Tejada.
After Ryan Cook retired the first two batters in the eighth, Tejada reached base on an error by shortstop Adam Rosales. The next two batters walked, setting up Dyson's game-winning single.
Dyson also walked, doubled, scored a run and stole two bases.
Aaron Crow (6-3) picked up the victory, pitching a scoreless eighth. Greg Holland pitched a spotless ninth to log his 20th save.
A's right-hander Jarrod Parker, who started the season 1-5 with a 7.34 ERA in his first seven starts, is 5-1 with a 2.49 ERA in his past 11 starts.
However, Parker had to settle for a no-decision in this one, leaving after 6 1/3 innings, allowing three runs, two earned, on five hits and three walks, while striking out four.
Parker, who had not pitched since June 29 when he left in the fourth inning against the Cardinals because of a right hamstring injury, gave up a single to Elliot Johnson, who snapped a 0-for-21 skid, and walked Dyson with one out in the seventh.
Jerry Blevins replaced Parker and walked Alex Gordon, his third free pass of the game, to load the bases. Eric Hosmer's sacrifice fly scored Johnson, making it 3-3.
Josh Donaldson hit his 15th home run of the season to tie for the team lead and give the A's a 3-2 lead in the sixth.
The A's jumped out to a 2-0 lead with single runs in the second and third innings.
Donaldson walked with one out in the second, stopped at second on Seth Smith's single and scored on Josh Reddicks's single to center. Smith and Reddick moved up a base on Dyson's errant throw home, but were stranded.
Donaldson's run-producing fly-ball single dropped into shallow right field and barely fair to score John Jaso in the third inning.
It was Donaldson's 100th hit of the season, making him the 14th Oakland player to reach that mark before the All-Star break and the first since Miguel Tejada in 2002.
The Royals got a run back in the third, when Dyson led off with a single to right and stole second. Dyson moved to third with one out on Parker's throwing error on a pickoff attempt and scored on Billy Butler's ground out.
Mike Moustakas' sixth home run with two out in the fourth tied the score, 2-2.
Royals right-hander Ervin Santana gave up three runs on seven hits and two walks in seven innings for his fourth consecutive no-decision.
