SNOQUALMIE, Wash., Aug. 25 (UPI) --
Roy Stewart followed his first-round 66 with a 4-under 68 Saturday to widen his lead to four shots in the senior Boeing Classic at Snoqualmie, Wash.
Playing competitively for the first time since missing the cut at last year's Senior British Open, the Monday qualifier and former PGA Tour pro was at 10-under 134 through 36 holes.
Scott Hoch, an 11-time PGA Tour winner who claimed his first Champions Tour victory this season, had a 67 to lead a group of four players who were tied for second place.
Hoch was tied at 6-under 138 with Bruce Vaughan (69), Gil Morgan (70) and Senior PGA Championship winner Denis Watson (69).
Stewart, a 53-year-old Canadian, could become the first open qualifier ever to win a Champions event wire-to-wire.
