Rain washed out the second round on Friday afternoon with only about one-third of the field completing their rounds. The scores were scrapped and the second round was replayed on Saturday, with 36 holes on Sunday.[3] Barber led at the midway point with a 136 (−4), two shots ahead of January and Doug Sanders.[4][5][6] A top putter of the era, Barber sank 120 feet (37 m) of putts on the last three holes of the final round to erase a four-stroke deficit to January and force a Monday playoff. At the 72nd hole, January had a two-stroke lead, but put his tee shot into the sand. With Barber on the green but an improbable 60 feet (18 m) away, January played conservatively for the bogey. Barber drained his third lengthy putt in as many holes (birdie-par-birdie) to even it up at the end of regulation.[7]
In the playoff, the two were tied at three-under after 16 holes, following January's birdie. Both had pars at the 17th, which effectively turned the 18th hole into sudden-death. Both tee shots found fairway bunkers, and Barber hit a 3-iron onto the green, 18 feet (5.5 m) from the cup. January found another bunker short of the green and could not save par from 15 feet (4.6 m).[8][9]
At age 45, Barber became the oldest winner of the PGA Championship, whose previous champions were all under age 40, with several at age 39. At the time, the only older major winner was Old Tom Morris at age 46 in 1867. Barber was surpassed in 1968 by Julius Boros at age 48.
It was the third major championship at Olympia Fields Country Club; it previously hosted the PGA Championship in 1925 (Courses 3 & 4) and the U.S. Open in 1928 (Course 4). The four 18-hole courses at Olympia Fields were reduced to two in the 1940s when the club sold half of its property. Course 4 became the North course, and the South course is a composite of holes form the other three.[10] The North Course later hosted the U.S. Open in 2003, won by Jim Furyk.
Play in the second round on Friday was ended by heavy rain in the early afternoon, with 54 of the 166 rounds completed. All scores were scrapped and the round was replayed on Saturday.[3]
