According to Anthony DiComo of MLB.com, the former NFL quarterback will start Wednesday at designated hitter against the Boston Red Sox. Rick Porcello, who won the American League Cy Young award last season, is the probable starting pitcher for Boston.
Tebow signed a minor league deal with the Mets in September after working out for teams at the end of August. While he was a highly touted baseball player in high school, the 29-year-old hadn't played in organized ball since then.
He moved onto the instructional league, where he hit a home run in his first game but struggled with consistency.
There were then mixed results during his Arizona Fall League run, where he produced a slash line of .194/.296/.242 in 70 plate appearances, per Matt Snyder of CBS Sports.
With 14 players heading to various teams for the World Baseball Classic, however, Tebow will get a shot to play for the major league club, as first reported by Joel Sherman of the New York Post.
Tebow was best known for his football career at the University of Florida, where he was part of two national championship teams while winning the 2007 Heisman Trophy. While he was a first-round NFL draft pick, he hasn't appeared in an NFL game since 2012.
