Tillman (shoulder) had a successful bullpen session Saturday and is slated to throw another one Monday, MASN's Roch Kubatko reports.

EDGE Analysis

Tillman had been limited to throwing off flat ground since having a cortisone shot earlier this spring, but he progressed to bullpen work Saturday. As it stands, the Orioles are aiming to have Tillman make a few minor-league starts beginning on April 11 before potentially getting him back to the majors in early-May.
