“We’re not prepared yet to set a timetable of 60 days for Chad,” general manager Ned Colletti said at the time.
That could change soon.
Tomorrow, Billingsley is scheduled to throw curveballs off a mound for the first time since having Tommy John surgery last April. The right-hander has been throwing curveballs off flat ground and fastballs off the mound since camp opened. However, the stress on his surgically repaired elbow — specifically, the ulnar collateral ligament that was transplanted from his left forearm — has been relatively light.
The curveball, Billingsley said Wednesday, “puts the most torque on the elbow.” At least one study has produced a different conclusion (specifically, that the fastball and curveball require the same amount of elbow torque), but the fact that he hasn’t attempted to throw the pitch with full force yet makes it a new test.
If he passes the test and emerges pain-free, Billingsley said he’ll be cleared to throw sliders. Adding the slider would give Billingsley the full arsenal he needs to face live batters in a rehab game.
In his last bullpen session Tuesday, Billingsley said his fastball topped out at 87 mph — the fastest he’s thrown the pitch since camp began. His fastball has was topping out around 95 mph prior to the surgery, but comparing games to bullpen sessions is unfair.
“When you’re throwing bullpens it’s hard to go max effort and hit a really high velocity,” Billingsley said. “You’ve got to have adrenaline, the hitter’s presence in the batter’s box.”
Billingsley recently said that, in a best-case scenario, he would be able to start a minor-league game by the end of camp.
We’ll know tomorrow whether or not that scenario is still realistic.
