Charlie Wi

Wi Chang-soo (위창수; born 3 January 1972), commonly known as Charlie Wi, is a South Korean professional golfer who currently plays on PGA Tour Champions. He previously played on the PGA Tour, European Tour, Asian Tour and the Korean Tour. He was a one-time winner on the European Tour and a seven-time winner on the Asian Tour.

Early life and amateur career
Wi was born in Seoul, and moved to Los Angeles, United States at the age of 10. He attended the University of California, Berkeley, after briefly attending the University of Nevada, Reno and had a successful amateur career.

Professional career
Wi turned professional in 1995. Early in his career, Wi played all over the world, competing on the European, Asian and Japanese tours. He had most success on the Asian Tour where he finished second on the money list in 2001, just behind Thongchai Jaidee, having won three times during the season.

Wi earned his place on the PGA Tour for 2005 when he successfully negotiated all three stages of the 2004 qualifying school. However, he did not do well enough in his rookie season to retain his card, and went back to play on the Asian Tour in 2006, finishing 4th on the money list. He also competed on the second tier Nationwide Tour, before returning to qualifying school where he regained his place on the PGA Tour for 2007.

In February 2006, Wi secured the biggest win of his career, when he won the Maybank Malaysian Open, an event co-sanctioned by the European and Asian tours.

In May 2011, Wi finished runner-up at a PGA Tour event for the fourth time in his career losing to David Toms at the Crowne Plaza Invitational at Colonial. Wi was seven strokes behind Toms at the halfway stage, but shot a 66 during the third round to take a one stroke lead into the final round. Wi held his lead until midway through the final round when Toms holed out from the fairway for an eagle and would eventually go on to lose by one stroke.

Wi finished as runner-up in February 2012 at the AT&T Pebble Beach National Pro-Am after taking a three stroke 54 hole lead into the final round. He shot a final round 72 to finish at 15 under, but lost out by two strokes as Phil Mickelson came from six back to claim the title with an 8 under par round of 64. This marked the fifth occasion on which Wi had recorded a second-place finish on the PGA Tour in his career.

In April 2023, Wi finished second to Mark Hensby in the Invited Celebrity Classic on PGA Tour Champions in Irving, Texas. Wi qualified as an alternate into the tournament but ended up losing on the fourth hole of a sudden death playoff after hitting his ball in the water.

Swing style
Wi's golf swing style fits the model known as stack and tilt, and he helped to choose this name. He is coached since 2005 by Mike Bennett and Andy Plummer, who consider him the best example of their swing model:

"Today Charlie is thought of by many players as one of the best ball-strikers on tour, and he exhibits the moves we teach better than any other player. If you want to know what Stack & Tilt should look like, watch Charlie Wi."

Wi does not transfer body weight to the trail leg on back swing but moves the weight forward during the whole swing, even with the driver. He performs a steep shoulder turn around a steady axis.
