Boyle (3-6) took the loss Saturday, coughing up five runs on five hits and four walks over five innings as the A's fell 9-5 to the Brewers. He struck out eight.

It was a typical outing for Boyle, as he generated 30 called or swinging strikes among his 104 pitches but issued at least three free passes for the seventh straight start in the majors, a streak that stretches back into April. The 25-year-old righty has a 5.40 ERA, 1.60 WHIP and 20:10 K:BB through 15 innings over three outings since getting called back up, but Oakland will let him work through his control issues in the hopes that he can emerge as a reliable rotation option. Boyle is scheduled to make his next start on the road next weekend against the Rangers.
