Luke Donald and Bill Haas were a stroke back. Donald had a 68, and Haas shot 69.
The biggest surprise was Snedeker, at No. 5 the highest-ranked player in the field. Days after leading the Masters on Sunday before faltering, the 2011 Harbour Town winner opened with a 73 and had a 71 Friday to finish at 2 over one over the projected cut line.
Seventeen players were unable to finish. The rain was forecast to continue overnight before the front moves out to sea and brings cooler temperatures but no rain.
Streelman had three birdies in his first four holes. He added a final birdie on the par-5 15th and parred out to move on top and put himself in contention on the tricky, narrow fairways and small greens of Harbour Town.
In Duluth, Ga., Bart Bryant and David Frost topped the first-round leaderboard Friday in the Champions Tour's rain-delayed Greater Gwinnett Championship. The start of play was delayed four hours by rain. There were 57 players still on the TPC Sugarloaf course when the round was suspended because of darkness. Bryant completed a 4-under 68, and Frost was 4 under with five holes left.
In Kapolei, Hawaii, Suzann Pettersen shot a 4-under 68 at wind-swept Ko Olina to maintain a one-stroke lead after the third round of the LPGA Lotte Championship. The 32-year-old Norwegian, a 10-time LPGA Tour winner, had a 14-under 202 total. South Korea's Hee Kyung Seo was second after a 66. Defending champion Ai Miyazato was third at 11 under after a 70.
