Thursday, Hurdle said Rodriguez would not be ready to pitch Sept. 1, when teams can expand their rosters to 40 players. However, the bullpen session marks the first time the left-hander will throw off a mound since sustaining the injury June 5.
Rodriguez made 12 starts before the injury, going 6-4 with a 3.59 ERA. Rookie Gerrit Cole has filled in since, holding his own in the Major Leagues with a 3.95 ERA through the first 11 big league starts of his career.
