World No. 1 Scottie Scheffler came into Masters week with the second-best odds to win the year's first major. 

But now, he holds both the world ranking's and PointsBet sportsbook's No. 1 spot as he currently sits alone atop the leaderboard halfway through the tournament. 

Scheffler's odds (courtesy of PointsBet) went from +1400 to start the week to +110 following Round 2 after grabbing a record-tying, five-stroke lead at Augusta National. 

He is currently the favorite over defending champion Hideki Matsuyama, who after a second-round 69 is +1100 (+5000 to start the week) with Dustin Johnson (T-6) and Cam Smith (T-6). Matsuyama is looking to become the fourth-ever player to repeat as Masters champion and the first since Tiger Woods in 2002. 

Meanwhile, Jon Rahm who was the betting favorite at +1100 coming into this week, is now listed at +6000 — with Matthew Fitzpatrick — for the field's 10th-best odds. The Spaniard is T-23 at 2 over through two days. 

Just a few spots down on the betting slip is Woods, who made the cut at 1 over and sits T-19, nine shots off Scheffler's 8-under lead. Woods' odds are 14th in the field at +9000. Coming into the week, he was +8000. The Big Cat, however, still is listed a better chance to win over many players who are in front of him on the leaderboard.
