NEW YORK — Noah Syndergaard threw his second bullpen session Friday since coming off quarantine this week. He tested positive for COVID-19 on his 29th birthday on Aug. 29 and after 10 days of isolation during which he stayed active by throwing into a mattress, he picked right back up and threw a side session.

The right-hander, who had to pause his ramp-up from Tommy John rehab after his first start in the minors late last month, told reporters that he still expects to pitch for the Mets before the season is over.

“Even though he lost some time, we feel he might be able to pitch for us this season,” said Mets manager Luis Rojas, who added he does not know when Syndergaard will go on another rehab assignment.

Syndergaard visited Engine 325, Ladder 163 in Woodside, Queens on Friday afternoon, continuing the Mets’ tradition of visiting firehouses to commemorate 9/11.
