Spieth: "The way I can play now kind of frees me up."

For all of the attention paid to 8th graders these days, Golf World's Tim Rosaforte looks at the quietly impressive year of 19-year-old Jordan Spieth.

With no status and questions about why he turned pro, has won over $900,000 after another top 10 at Colonial.

Spieth's ball-striking stats explain his success. After his latest top-10 at Colonial -- which helped him get into this week's Memorial -- the teenager sat 10th in total driving and ninth in the all-around ranking. Sectional qualifying for the U.S. Open comes June 3 in Dallas, which could mean 288 holes of competitive golf over a three-week period, including last week's British Open qualifier in Big D, in which a T-22 finish failed to earn him a spot in the field at Muirfield.

If Spieth were eligible for FedEx Cup points, he would be ranked in the top 60. His World Ranking is 141st, up from No. 809 at the start of 2013. "My expectations have changed," he said. "Down the stretch [at tournaments] I'm not worried about seventh-place finishes, like I was in Tampa. I can be more aggressive, which may have hurt me this week, but that's part of learning how to win."
