The Mets announced on Sunday that they have promoted former NFL quarterback Tim Tebow from Class-A Columbia to High-A St. Lucie, the third highest minor league level.

Tebow, 30 in August, was hitting just .222/.311/.340 with three home runs and 22 RBI in 63 games for Columbia at the time of his call-up. He has fanned 69 times this year.

Mets general manager Sandy Alderson said that Tebow’s exit velocity was a big factor in the decision to promote him.

“It’s not like he’s tearing up the league, but at the same time all of the indications are positive in terms of various things we look at — chase rates and exit velocity,” Alderson said. “The bottom line is the average isn’t there, but he’s improving.”

Tebow signed with the Mets last September and has since appeared in the Arizona Fall League, Major League Spring Training and Columbia before receiving his promotion.
