SCOTTSDALE, Ariz. -- Tim Tebow is ready for the next step in his journey to becoming a Major League player.
The former Heisman Trophy-winning quarterback is expected to be in the starting lineup at Glendale on Tuesday afternoon as the Scottsdale Scorpions begin play in the Arizona Fall Leagu.
"I think it'll be a great challenge, I think it'll be awesome," Tebow said. "I think it'll be a challenge not only as far as competing, but I think it'll be a blessing as far as learning from a lot of guys that are doing it at a high level and getting ready to be at the highest level, that's great. It's a great opportunity for me."

Tebow signed with the Mets for $100,000 in September after having not played competitive baseball since his junior year high school in 2005.
Tebow homered on the first pitch he saw in the Florida instructional league and finished with a .286 average (4-for-14).
The Arizona Fall League will certainly be a step up in competition, but Tebow is embracing the challenge and believes it'll be a good measuring stick.
"I think it'll give me a great idea of where I'm at," Tebow said. "It'll be very competitive. You're facing a lot of guys that are going to be at the highest level very soon."

Tebow is scheduled to be in Arizona each week from Monday though Thursday, with the Mets granting permission for Tebow fulfill his duties as a college football analyst with ESPN's SEC Network on Fridays and Saturdays. Sundays are off days in the Fall League.
The Major Leagues may be the ultimate goal, but the 29-year-old won't ultimately define his success by whether he ever makes his MLB debut.
"For me, success doesn't come in where I finish, what league," Tebow said. "I think success comes in giving everything I have. I think ultimately that's what you can control and that's what I'm going to try to control -- my attitude and my focus every single day."
The results are yet to be seen, but it'd be hard to find someone willing to question Tebow's makeup or work ethic. He knows there's a long road between where his is and Citi Field in New York, but he's not shying away from it.
"This is not an easy game," Tebow said. "Hitting a 90-something mph fastball is not easy. I don't want easy."
