Worth noting

• Parnell called his surprise mound work Friday "a little confidence booster" in his rehab from neck surgery. The Mets originally did not expect Parnell to take the mound until the end of this month, but the closer did so on a limited basis Friday after consulting with trainers.

• Right-hander Jeremy Hefner tweeted Sunday that doctors cleared him to begin a throwing program for the first time since Tommy John surgery in August. Hefner, who posted a 4.34 ERA in 24 appearances last year, could return to the Mets late this season.
