With the victory, Slocum kept his streak of phenomenal performances alive, having won the Greater Cleveland Open two weeks ago and placing third last week at the Dayton Open.
He needs one more victory this season to reach the PGA Tour under the tour's Battlefield promotion, which allows any Buy.Com Tour member who wins three times in a season to move on to the PGA Tour.
After seeing his Buy.Com Tour-record streak of 106 consecutive holes without a bogey come to an end in the second round, Slocum came prepared for the final round.
'I wanted to try and make some birdies and avoid the mistakes,' said Slocum. 'If I played my game, I felt like someone was going to have to shoot a really good score to catch me.'
Slocum birdied four of the first eight holes to push to 23-under, eight strokes ahead of his closest challengers. He played the final 10 holes in even par, with two bogeys and two birdies.
He found trouble at the par-4 15th where pulled an 8-iron into the water to the left of the green.
'I looked at the board at that point,' Slocum said. 'I really wanted to know just how aggressive I needed to be on the chip. I wanted to see if I needed to take my medicine and try to just two putt. Those last three holes are tough.'
He pitched the ball to six feet to set a bogey putt that kept his lead from shrinking any more.
Joe Daley and Don Pooley were still five strokes off the lead at this point and Slocum went on to become the tour's first two-time winner this year.
