Mike Wein had just changed the channel briefly at the end of the fifth inning of Sunday’s World Series Game 4 between the Red Sox and Cardinals when his cellphone started blowing up with text messages.

As part of Major League Baseball’s “Stand Up To Cancer” program, players from both teams were lined up holding signs for people they were supporting or honoring in the fight against cancer. Red Sox outfielder Jonny Gomes was holding up a sign that said, “I Stand Up for Brady’s Bunch.”

Brady’s Bunch is a club lacrosse program started by Wein, a 1991 graduate of Framingham South High School, to help promote awareness and support for his now 5-year old son, Brady, who suffers from a form of cancer known as acute myelogenous leukemia (AML).

“I got a bunch of texts from people who saw it,” Wein said, “to which I responded, ‘And now he’ll do what the Bunch does and he’ll come up big.’ And then the rest was history.”

In a script even the best writers in Hollywood couldn’t have concocted, Gomes followed that moment with a three-run homer in the top of the sixth to give the Sox a 4-1 lead. They went on to post a 4-2 victory and even the World Series at 2-2.

“I texted (Gomes) when he hit it with tears streaming down my face thanking him,” Wein said. “I knew that this was pretty cool with him but I didn’t know it was this close to his heart. I met this guy two years ago and on national television he comes out with that? Honestly, it’s too much. It’s great, it’s just unbelievable.”

The surprises weren’t over. Gomes talked about Brady during the postgame press conference, saying, “You want to talk about battle-tested?” Wein also said he received a text back from Gomes at 2:30 a.m. that read, “This is so crazy but what did you think was going to happen?”

Gomes was truly touched by Brady’s battle.

“I don’t have to be a professional ballplayer to give this kid any attention or give this kid the respect he deserves for what he’s battled in his young life,” Gomes said before Game 5 last night in St. Louis. “He’s a special kid. He truly is. You look at a 50- or 60-year-old who has a stroke, they get a little taste of adversity and they’re like, ‘Now I’m going to live my life. Now I’m going to respect every breath of fresh air. Now I’m going to respect the sun.’ This kid got that at 6 months old. He’s a complete and utter breath of fresh air to be around. It puts everything into perspective.”
