MIAMI -- Terry Collins censored himself during a postgame interview session after the Mets committed six errors in a 9-6 loss to the Miami Marlins on Labor Day.

“I’m not sure I can say it publicly,” Collins said about sharing his true thoughts on the error total. “It wasn’t just that. A lot of phases of the game weren’t very good.”

Asked if the performance was an embarrassment, Collins added: “Well, it’s not a big-league baseball game.”

Dilson Herrera produced his first major league homer, but also had two errors Monday.

The error total fell one shy of matching the franchise record. Three of Monday’s errors came in a decisive three-run eighth inning in which the Marlins produced only one hit.

Jeurys Familia bounced a throw to first base after fielding a bunt, setting up runners on the corners with none out with the score tied at 6. Familia bounced a wild pitch as the go-ahead run scored. And Familia threw wide to the plate after fielding another baseball in the inning, allowing the Marlins to take a two-run lead. Erik Goeddel walked in a run in his major league debut later in the eighth.

“I think I’m trying to be too quick,” said Familia, who has been plagued by throwing difficulties after fielding comebackers throughout the season. “Before I get the ball, I’m thinking, ‘I’ve got to throw perfectly.’”

Without mentioning second baseman Dilson Herrera by name, Collins noted Familia’s bounced throw to first base usually is scooped up by the fielder manning the bag.

“Those plays are made at this level,” the manager said.

Herrera committed two errors in the game -- booting one grounder and later rushing an ill-advised throw to first base.

Regardless, Collins said Herrera is undergoing an understandable adjustment period to the majors. Infield grass is mowed tighter and therefore plays faster. And runners motor down the first-base line with more speed and/or hustle than in the minors.

“He’s going to be fine,” Collins said about Herrera. “He’s a good-looking little player. He’s got to get used to the speed of the fields here. They’re shaved down pretty good. The infields are pretty fast -- everywhere, in every ballpark. He’s got to get used to the speed of the game up here. I think when he does we’ll see some different results.”

“No excuses,” Herrera said through an interpreter. “Errors are going to happen. I’m going to make mistakes and errors. I’m not perfect. But I’m also going to continue to work on it and get better.”

Collins noted the fielding wasn’t the only phase of Monday’s game that underwhelmed. The manager left Zack Wheeler in after David Wright committed an error in the fifth, trying to get Wheeler qualified for the win despite a high pitch count. Instead, Wheeler ultimately was charged with five runs (two earned) in 4 2/3 innings while logging 114 pitches.

“I felt terrible,” Wheeler said. “… I was just leaving my breaking balls up in the zone. Nothing was really working for me. Just a bad day.”

Giancarlo Stanton had a solo homer and a couple of other hard-hit shots against Wheeler.

“I’ve done pretty well against him so far, but if he was at our place today, he would have had three home runs against me,” Wheeler said.

Regardless, Collins concluded, the team’s underwhelming performance was the result of lack of execution, not something more sinister.

“There’s no lack of effort,” Collins said.
