The Mets have their fourth outfielder and occasional DH — and now their fantasy football league could get a lot more interesting.

The team is finalizing a deal with free-agent outfielder Tommy Pham for one year and $6 million on Wednesday, The Post’s Jon Heyman reported.

And their search for left-handed bullpen help is ongoing, with Andrew Chafin and ex-Yankee Zack Britton — who played for Buck Showalter in Baltimore — among the possibilities.

The 34-year-old Pham was one of just a few outfielders remaining on the free-agent market after Adam Duvall agreed to a one-year, $7 million deal with the Red Sox.

Andrew McCutchen, another consideration, previously headed back to Pittsburgh.

Jurickson Profar also remains available, but may be seeking a larger role.

Pham is coming off a subpar year split between the Reds and Red Sox and finished with a .686 OPS, his worst in a full season. He was better with the Padres in 2021.

He made headlines last season when he walked up to Joc Pederson of the San Francisco Giants before a game and slapped the outfielder over what Pham called a feud over a fantasy football league the two were a part of.

At the time of the incident, Pham was with the Reds, and was pulled from that day’s lineup.

Afterwards, Pham expressed no regret.

“Regarding the Joc situation, I don’t feel sorry for what I did,” Pham said last year. “There’s a certain level of respect that was crossed. Joc was disrespectful and I don’t condone, you know, the way he was talking to me in the group chat through the text. I don’t condone that.”

Pederson told reporters at the time it stemmed from him being accused of cheating in the league.

Pham said he dropped out of the league and also pointed a finger at the league’s commissioner, Mike Trout.
