Tony Romo continues his quixotic journey to become a full-time professional golfer this week, thanks to a sponsor’s exemption he received to play the AT&T Byron Nelson at Trinity Forest Golf Club in Dallas.

And while Max Homa was not on the board last week before he won the Wells Fargo Championship, bettors do have the option to wager on Romo this week. He’s a 10,000-1 extremely-long shot to win the Byron Nelson, according to odds posted at the The SuperBook at Westgate Las Vegas and at golfodds.com.

Among the legit professional golfers in the 156-player field, Brooks Koepka is the clear favorite at 13-2. Koepka will likely use this event in part as a tune-up to firm his game for his PGA Championship defense next week at Bethpage Black.

Hideki Matsuyama is the second choice at 16-1, while hometown favorite Jordan Spieth is fetching 18-1 odds.

Those who might want to take a shot at a Romo victory, be warned. He says he’s using the event to measure and improve his game as much as he is to compete.

On the flip side, Romo will be playing his home course.

His over/under for Round 1 is 77.5 on the 7,558-yard, par-71 course.
