Noah Syndergaard fails again with one of his favorite sensors

For a second consecutive start, Noah Syndergaard had someone else than Wilson Ramos to catch him, as Callaway inserted Tomas Nido into training.

Nido became Syndergaard's personal seeker earlier this season. In his previous debut, Syndergaard had captured Rene Rivera – another favorite target -.

"Ramos has caught four in a row, and we still want Noah to go," Callaway said before the Mets' victory over the Marlins (5-4, 11 innings). "We want him to finish his last couple strong and I hope it will be the right recipe." Obviously, things did not go very well last time and today we feel that the time has come for Nido to leave. "

Instead, Syndergaard allowed four earned runs for a fourth straight outing. He also gave 10 hits in just five innings. Syndergaard is scheduled to start the final Mets game of the regular season Sunday against the Braves at Citi Field.

"He's having trouble right now," Callaway said. "He has one left and it will be the last day of the season."

Paul Sewald took the win, the first of his career after starting from 0 to 14 years old. It was the longest series of debuts in NL history.

"It's a meaningless statistic, but it's good to have one," Sewald said.

Jacob DeGrom's final start is scheduled for Wednesday against the Marlins, giving the right-handed man one last chance to tweak his stats in the NL Cy Young race. DeGrom's ERA has gone from 2.71 to 2.51 in his last two starts against the Dodgers and Reds.

Robert Gsellman will perform a second training session (Wednesday or Thursday) live before deciding to activate him from the casualty list. The right-hander – who missed last month with a lat torn in part – said he would like to launch this season for the peace of mind as winter approaches.

Dominic Smith is scheduled to be examined Wednesday to determine if he is medically cleared for the return of a fatigue fracture to his left foot. Smith took the batting exercises for a second day in a row.

The club's director, Mets, Tony Carullo, was one of the team's employees honored at a pre-game ceremony. Carullo, who has spent 51 years in the organization, is retiring at the end of the season. He started in the organization as a batboy and has been managing clubhouse since 1975.
