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. 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.
