Wheeler (elbow) threw a 20-pitch bullpen session Friday, the most pitches he thrown in a session to date, Newsday reports.
Wheeler, for the first time, threw two-seam fastballs and change-ups in addition to four-seam fastballs. He will steadily progress to a full bullpen session and then likely a simulated game prior to kicking off a rehab stint in the minors. That rehab assignment is likely to last a full 30 days before he rejoins the Mets, possibly around the July 1 target date.
