SAN FRANCISCO — Tim Tebow’s minor league tour is headed back to Florida.

The former Heisman Trophy was promoted Sunday to the Mets’ High-A St. Lucie affiliate after a hardly eye-opening 2 ½-month stint at Low-A Columbia.

Tebow, 29, entered Sunday with a .222/.311/.340 slash line with three homers and 23 RBIs in 63 games for Columbia. He is scheduled to play his first game for St. Lucie on Tuesday.

“His last two or three weeks trended pretty well and given all the other circumstances, age and so forth, we felt this was the right time to promote him,” general manager Sandy Alderson said.

But it seems the Mets were determined to promote Tebow regardless of his numbers. The Post reported last month that team brass had discussed the idea of bumping up Tebow after the South Atlantic League All-Star Game. That event was held last week,

Tebow’s return to baseball — a sport he had last played competitively in high school — came in September when he reported to the Mets’ instructional league before he appeared in the Arizona Fall League. He was a minor league invitee to spring training, and appeared in nine Grapefruit League games for the Mets and batted .148.

The Mets remain intrigued with the former quarterback’s athleticism and the positive influence he can have on the organization’s younger players.

“I think we’re pleased with [Tebow’s] first half of the season,” Alderson said. “It’s not like he’s tearing up the league, but at the same time all indications are positive in terms of various things that we look at, in terms of chase rates, exit velocity.”

Alderson was asked if Tebow has a ceiling as a player.

“I don’t think about his ceiling,” Alderson said. “There was a chance he would completely bomb in spring training, and that didn’t happen. I think his performance there justified his assignment to a full-season club. He went to Columbia and I wouldn’t say he’s excelled there, but I think what he’s done there, given all the circumstances, justifies the promotion to St. Lucie.”
