CINCINNATI — Phil Regan wore the “interim” label when he was named Mets pitching coach in June, leaving his status with the club in question regardless of results.

Mets pitchers have largely thrived under the guidance of the 82-year-old Regan, but at this point he hasn’t received assurance he will be back.

“At my age, whatever happens, happens,” Regan said Sunday before the Mets beat the Reds 6-3 at Great American Ball Park.

Regan, who spent the previous decade as a minor league pitching coach within the Mets’ system, assumed major league duties after the team fired Dave Eiland near the season’s midpoint. Entering Sunday, Mets pitchers owned a 3.52 ERA in the second half. That ranked third in the major leagues. Mets starting pitchers had a 3.06 ERA, which ranked first over that stretch.

Is Regan happy with the pitching staff’s progress?

“I think for the most part I am,” he said. “Some of them have made good changes.”

Regan has divided responsibilities with pitching strategist Jeremy Accardo, who has overseen much of the analytics and game-planning.

“I’ve had a good time, but all I am thinking right now is hopefully we can win and get in the playoffs,” Regan said. “I’m sure [the Mets] will decide what they are going to do and whatever happens, happens.”

Most of the Mets’ coaches have expiring contracts after this season. Manager Mickey Callaway is signed through 2020, but his status is very much in question.

Robinson Cano left the game in the fourth inning after having been hit by a pitch on his left big toe in his previous at-bat. X-rays were negative, according to the Mets. Callaway said Cano may rest on Monday with the Marlins scheduled to pitch lefty Caleb Smith.

The Mets’ victory was their 81st — ensuring a third non-losing season for the franchise in the past 11. The Mets had winning seasons in 2015 and 2016 during that stretch, reaching the postseason both years.

With 113 first-inning runs this season, the Mets trail only the Reds (126) in that category.

Brandon Nimmo’s ninth-inning homer gave him 100 career RBIs.
