Parnell threw 36 pitches during the session, and may throw another live batting practice session on Sunday.
The 29 year old had been slowed a bit recently by some tightness in his quad, but any issue appears to be behind him.
Parnell was tremendous for the Mets last year in a breakthrough season as the team’s closer.
He converted 22 of 26 chances while posting a 2.16 ERA and 1.00 WHIP in 50 innings pitched before the herniated disk ended his season prematurely.
Parnell has been taking things at a deliberate pace this spring, but appears to be on schedule.
There was some concern early on over whether he’d be ready for opening day, but it appears that concern was a bit misguided.
He’ll likely make his Grapefruit League debut in a bit over a week.
