There’s a chance the A’s might adjust their rotation after one time through.

No. 5 starter Raul Alcantara performed poorly in his first start Friday, allowing eight runs in two innings. The rookie right-hander gave up two homers, including a grand slam by Nomar Mazara. Long man Jesse Hahn, who was Oakland’s No. 3 starter the first half of the 2015 season, took over and worked six strong innings, hitting 97 mph with his fastball and allowing two runs.

The team has a day off at Kansas City on Tuesday, and manager Bob Melvin said that will factor into his decision. With the extra day, the A’s could skip Alcantara or push him back to allow him to work on some issues.
