Tim Tebow isn’t going to make his big league debut this season, no matter what speculative fans and arm chair scouts say on Twitter.

That’s what New York Mets General Manager Sandy Alderson seemed to indicate Friday, when asked by reporters whether the 29-year-old former football star’s recent success at the plate might translate into a September call-up.

“Never crossed my mind until about 10 days ago when somebody said it was likely to happen,” Alderson said (via ESPN). “I don’t foresee that kind of scenario.”

The question isn’t completely far-fetched, at least as much as it would have been a month ago when the Heisman Trophy winner turned minor leaguer was struggling in the low-Class A South Atlantic League. Tebow is hitting .321 since his promotion to the advanced-Class A St. Lucie Mets, with 11 RBI, three home runs and six walks in 17 games.

He also is on a 12-game hitting streak after going 1 for 4 with a triple, RBI and run scored in Friday’s 8-5 win over the Daytona Tortugas. The Mets celebrated the win in style, sporting “Buddy the Elf” jerseys for the final game of their series.

It was a good series for Tebow, who launched a walk-off homer Thursday night to hand the Mets a 5-4 win over Daytona. It was his first walk-off homer since high school.

“I just wanted to try and come through in the end and help win it for our team,” Tebow said after Thursday’s game (via the Daytona Beach News-Journal). “I’m just thankful to get that opportunity.

The New York Mets sit in fourth place in the National League East and are nine games out of a wild-card slot, so the likelihood of them needing postseason reinforcements is slim as of now. But there is still a lot of baseball left to play — both for the big league Mets to get back into the mix and for Tebow to work his way up the minor league ladder this season.

And at this point, would it surprise anyone if New York’s Labor Day giveaway is a Tebow bobblehead?
