KANSAS CITY, Mo. (AP) - Jeremy Guthrie allowed only three singles in seven innings, and the Kansas City Royals rolled to a 5-0 win over the Oakland Athletics on Tuesday night.
Guthrie, who struck out a season-high eight, ran his scoreless streak to 15 innings. He has yielded eight hits and struck out 14 in his past two starts, victories over the A's and the Chicago White Sox.
Guthrie (5-12) is 2-3 in five starts with the Royals, who acquired him in a July 20 trade with Colorado for left-hander Jonathan Sanchez.
Tim Collins and Greg Holland completed the shutout for Kansas City. Collins struck out all three batters he faced in the eighth inning, boosting his total to 77 - a Royals' strikeout record for a left-handed reliever.
The A's failed to get a runner past second base and were shut out for a major league-leading 14th time.
Alex Gordon and Eric Hosmer delivered run-scoring singles in the Royals' five-run fifth inning that also featured sacrifice flies by Chris Getz and Billy Butler.
Kansas City also scored an unearned run after Oakland second baseman Jemile Weeks failed to handle Alcides Escobar's bouncer. That allowed Lorenzo Cain, who had walked, to score.
A's rookie right-hander Jarrod Parker (7-7) was pulled after 4 2-3 innings. He gave up five runs, five hits and two walks. Parker is 2-4 with a 6.15 ERA, and batters are hitting .309 against him in his past seven starts.
He was 5-3 with a 2.46 ERA and an opponents' batting average of .209 against him in his first 13 starts.
In the third inning, Josh Donaldson and Coco Crisp singled, but Donaldson was put out in a rundown between second and third. Right fielder Jeff Francoeur earned his 13th assist on the play, tying him for the major league lead among outfielders.
Notes: The A's placed 3B Brandon Inge on the 15-day disabled list with a sprained right shoulder. Inge joins eight teammates on the DL. The A's have used the DL 19 times this season. ... Oakland recalled INF Josh Donaldson from Triple-A Sacramento, where he was hitting .335 in 51 games. . The Royals asked for unconditional release waivers on INF Yuniesky Betancourt, who was designated for assignment on Aug. 5 with a .228 batting average. . Cain became the 13th Royals player to bat eighth. . A's RHP Brandon McCarthy, Wednesday's pitcher, will make his second start since coming off the disabled list. McCarthy, who was out because of a shoulder strain, is 6-0 with a 2.25 ERA in his past eight starts. Rookie LHP Will Smith will start for the Royals.
