Jan. 25, 2001 is a special day in PGA Tour history. At least so far, it's the only day in PGA Tour history on which a hole-in-one was recorded on a par 4.
Andrew Magee made the ace at the short par-4 17th hole at TPC Scottsdale during the Phoenix Open. Magee's drive on the 332-yard hole actually ricocheted off the putter head of Tom Byrum, who was on the green at the risk-reward hole, before finding its way into the cup.
No video exists of Magee's ball going in the hole. However, Magee described the shot on-air when he was an analyst on Golf Channel (he made an unfortunate Girl Scout joke that cost him his job) over footage of Byrum's reaction as the ball caromed off his putter and his subsequent celebration.
