EDGE Analysis

Doolittle was taught the pitch by his younger brother Ryan, also a reliever in the A's system. Doolittle has also been working on his slider as he tries to find some breaking pitches to mix in with his fastball. Doolittle enters the spring as the A's closer, but the team will be keeping an eye on his velocity in the spring to ensure that his shoulder is fully recovered.
