NEW YORK (WFAN) — Darren Meenan, owner and operator of Mets-themed t-shirt company The 7 Line, wants to make a difference for Hall of Famer Gary Carter.

Carter was diagnosed with an inoperable brain tumor last month. Like many baseball fans, Meenan has since had the the former 1986 Mets star in his thoughts and prayers.

Now, Meenan is looking to raise money for Carter’s cause — the best way he knows how.

A new shirt, with the message “We love ya Kid” above “Carter” emblazoned in script, is available on pre-sale from The 7 Line’s website for $25 until June 21.

“With all the media attention I got the other day, from my Don’t Trade Reyes sign and eventual ejection from the ballpark, I am now given more of a voice to help for a good cause,” Meenan told on Wednesday. “The 7 Line has a strong following of die-hard Mets fans and together we can hopefully donate a great amount of money towards cancer research.”

According to Meenan, it was Kerel Cooper from On The Black, a Mets video blog, who first approached him with the idea.

Meenan says he’d like to donate all the profits to the Gary Carter Foundation. He reached out to the organization “about a week ago” — to no avail.

But there’s a backup plan in place.

“100% of the profits (roughly $20) from each shirt sold will be donated to the Gary Carter Foundation OR the American Cancer Society,” Meenan wrote to his blog on Tuesday. “Either way money will be sent somewhere for a good cause in the name of a Met player we all loved seeing in the Orange and Blue.”

Meenan has a message for Carter: “We are all pulling for you Gary!”

He also posted a message for the Mets.

“The Mets haven’t retired Gary’s #8 yet but I hope they have something planned before the end of the season,” Meenan wrote. “I am sure it would mean a lot to Gary, his family and his fans around the world.”

It’s a sentiment growing among the Citi Field devotees, especially on Twitter.

“Should the Mets … retire Gary Carter’s number? The simple answer is of course,”’s Jeff Capellini wrote on Monday, “followed by what the hell have they been waiting for?”
