SILVIS, Ill. (AP) -- Steve Stricker has broken the PGA Tour's 54-hole record with a 9-under-par 62 Saturday that gave him a six-stroke lead in the John Deere Classic.

Stricker, the tournament's defending champion, was at 25-under 188 heading into Sunday's final round. The old 54-hole record of 189 is shared by John Cook, Mark Calcavecchia and Tommy Armour III.

Stricker can now take aim at Armour's 72-hole record of 254. Stricker needs a 65 to set the new mark.

Paul Goydos, who shot just the fourth 59 in tour history in Thursday's first round, was tied with Jeff Maggert for second at 194. Maggert shot a 63 on Saturday and Goydos a 67.
