Cole (elbow) had his rehab assignment transferred from Double-A Somerset to Triple-A Scranton/Wilkes-Barre on Saturday.
Cole has already made five rehab starts -- two with High-A Hudson Valley and three with Somerset. He threw 77 pitches over five frames in his most recent outing, so he appears close to being fully ramped up, though Yankees manager Aaron Boone stated following Cole's last appearance that he'll need at least two more rehab starts. Cole is slated to start for Scranton/Wilkes-Barre on Saturday, per YES Network, so he could still be ready to join the Yankees' rotation before the end of May.
