Worth noting

• Rehabbing lefty Eric O'Flaherty (Tommy John surgery) threw a 30-pitch bullpen session in Oakland on Tuesday and is nearing the next step of facing hitters. Barring any setbacks, he could join the A's bullpen as soon as June.

• Infielder Jake Elmore remains with the A's rehabbing a strained left quad after reinjuring it last week.
