The 24-year-old from Georgia was tied with Sweden's Robert Karlsson before play was suspended on day three, with both men on 15 under following seven holes of their third rounds.
The tournament had seen round two completed early on Saturday but the players ran out of time and endured an early start on the final day in another bid to catch up time.
English claimed a third-round 68 and then moved to 20 under par, two shots ahead of South Africa's Rory Sabbatini midway through the fourth round - with Karlsson and Brian Stuard of America one shot further back on 17 under.
Chris Stroud was on 16 under par, while fellow American's Justin Leonard and Justin Hicks finished their fourth round on 15 under after both carded a final-round 67 on Sunday.
Hicks recorded seven birdies - six of them on the front nine - but a double bogey on the 14th hole and a bogey on the 18th meant he dropped back.
Leonard followed up his penultimate round 65 with six birdies and two bogeys.
New Zealand's Tim Wilkinson was in a three-way tie in 10th on 13 under par alongside American duo Bob Estes and Kevin Stadler with three holes of his fourth round to play.
