Many top PGA Tour stars entered this week's Shell Houston Open hoping to tidy their games before next week's Masters Tournament.
Guys like Adam Scott and Jordan Spieth — past Masters champions — missed the cut, which paved the way for others to step up.
Sung Kang has been the most opportunistic through three rounds. Still looking for his first PGA Tour win, Kang enters Sunday's final round with a three-shot lead over Rickie Fowler.
Fowler caught Kang near the end of Round 3, but he faltered down the stretch by playing the last two holes in 3-over par. He will have to regroup and figure out the closing stretch to earn his second win of the year.
Here are Sunday's top contenders:
Sung Kang (-17) — Kang, who tied the course record and set the 36-hole tournament record after Friday's 9-under 63, came back down to earth a bit in Round 3. Having watched his lead momentarily evaporate Saturday after Fowler rose to 8 under for his round, Kang should be ready to fire at some pins in Round 4.
Rickie Fowler (-14) — Just when it looked like Fowler was going to surpass Kang and take control of the tournament, he went and made a mess of the closing holes. A bogey on 17 and a double-bogey on 18 dropped him three shots behind Kang. Fowler has had trouble closing out events in recent seasons, so it might be a good thing he has to come from behind this week.
Russell Henley (-13) — Henley is quietly nudging his way into contention. With all the attention on Fowler and Kang, Henley has climbed four shots back relatively unnoticed. With back-to-back top-5 finishes in this event, Henley has become a serious horse for the course. He has two career wins, so he's not afraid of closing out events.
Luke List (-12) — List came out of nowhere Saturday to enter the conversation. His 7-under 65 was Saturday's best round. He may need to do something similar in Sunday's final roundto win.
