Just ask opposing Double-A managers who raved about the strides the former Heisman Trophy winner has made this year with the Mets' affiliate in Binghamton. They have cited his improved plate discipline, pitch recognition and opposite-field power.

"He looks like a different guy than last year," Double-A Hartford manager Warren Schaeffer told The Post in a phone interview.

After quitting football following failed stints with the Broncos and Jets, and signing in September 2016 with the Mets, the doubts were understandable. Tebow, who won two college football national championships at Florida, hadn't played baseball since his junior year of high school. In 2017, Tebow hit just .226 with eight home runs and a .656 OPS split between Single-A Columbia and Port St. Lucie. At 30 years old, he didn't exactly distinguish himself during spring training, either.
