Thomas Pieters
Odds: 70/1
A true boom-or-bust pick, Pieters could miss the cut, as he did at the Honda Classic and Arnold Palmer Invitational, or he could be in contention on Sunday, as he was at the Genesis Open and the WGC-Mexico Championship.
Nevertheless, while he brings inconsistency, this is the kind of high-upside player you're looking for when you're making long-shot bets in this range. He's big enough off the tee, he has the necessary short game (ninth in strokes gained approaching the green and 24th in strokes gained putting), and when he's in form, he can go really low.
He's another one making his Masters debut, so I would tread lightly, but the potential he brings is enough to invoke at least a small bet. (Getty)
