Sandy Alderson recently said the “entertainment” factor was a big reason why the Mets signed Tim Tebow to a minor-league deal.

And he was right: Tebow entertains and brings in the fans. The St. Lucie Mets announced Friday that they set a new single season home attendance record of 108,057.

“Look, we signed him because he is a good guy, partly because of his celebrity, partly because this is an entertainment business,” Alderson said at the time. “My attitude is ‘Why not?’ ”

Nevertheless, Tebow is proving to be more than a circus act. He is hitting .273 with five homers and 22 RBIs, prompting The Post’s Mike Vaccaro to say he’s a legitimate minor league prospect and should be treated as such.
