Mets rookie RHP Robert Gsellman let up a career-high seven runs and game up 10 hits during a loss to the Nationals at Citi Field on Thursday.
"They were just hitting the ball where the defense wasn't," Gsellman later said. "They had some hard-hit balls, but I can't take it back."
The Nationals entered the fifth inning with a one-run lead, but tacked on five runs to put the game out of reach in large part due to a triple by Daniel Murphy and a home run by Michael Taylor.
"Robert has been pitching so well, and certainly that was a bit of a downer in the fifth inning," Collins said. "We just have to come out tomorrow and play with some energy."
Gsellman entered the game having won each of his previous three starts, during which he allowed a total of six earned runs.
The only other time this season Gsellman surrendered 10 or more hits was against the Braves on April 26 against the Braves.

Gsellman had spent time in the bullpen during late May. However, he is expected to remain in the rotation now that Matt Harvey is expected to miss several weeks with a shoulder injury.
Sandy Alderson said Thursday the Mets will use Gsellman, Jacob deGrom, Zack Wheeler, Steven Matz, and Seth Lugo, and are likely to lean on Tyler Pill (currently with Triple-A Las Vegas) or Rafael Montero as an occasional sixth starting pitcher.
Alderson also said he not currently seeking external help for rotation, despite announcing that Noah Syndergaard is unlikely to return until at least late August.
