Just when it appeared the A’s right-hander might get through six innings in pretty fair shape, he allowed a two-out Grand Slam on a 3-2 pitch to fellow rookie Cam Gallagher.

Compounding the problem was that ball four was a wild pitch that allowed Alcides Escobar to score to give Kansas City a 2-1 lead.

Since his most recent win, a five-inning stint in the A’s 3-0 victory over the White Sox on June 23, Cotton has gone winless in five starts and has spent time on the disabled list because of a blister on his right thumb.

He allowed a run in the first, and the A’s tied it in the bottom of the inning as Marcus Semien launched a Jakob Junis pitch high off the wall in left-center for a triple with one out.

Cain raced a long way and made an excellent catch just before slamming into the part of the wall that displays an Xfinity ad.
