Warren was born in Rutherglen, South Lanarkshire.
Warren began his professional career on the second tier Challenge Tour, and finished top of the Challenge Tour Rankings in 2005, to graduate directly to the European Tour. Again he finished the season ranked 42nd on the Order of Merit.
He represented Great Britain & Ireland at the 2001 Walker Cup, where he holed the winning putt. He turned professional in 2002. He claimed his first European Tour title during his first season, at the EnterCard Scandinavian Masters.
At the end of the year, he partnered Colin Montgomerie to second place for Scotland in the 2006 WGC-World Cup, after losing out to Germany in a playoff.
In 2007 Warren captured the Johnnie Walker Championship at Gleneagles, after overcoming Simon Wakefield on the second hole of a sudden death playoff. With four holes to go, Warren held a one shot lead over the field, but finished poorly, dropping four shots in four holes, including a double-bogey at the 15th, to fall one shot outside of a playoff.
Warren endured more final round heartache in April 2013 at the Open de España. Warren had led for most of the final round before consecutive bogeys at the 14th and 15th put him one shot behind.
However he picked up a birdie at the 16th, but then proceeded to three-putt both the 17th and 18th to once again fall a shot outside the playoff and into a tie for fourth.
A few weeks later at the Bayerische Motoren Werke Professional Golf Association Championship at Wentworth, Warren lost out in a three-man sudden-death playoff for the title. He birdied the first four holes on the back nine during the final round to go into a one shot lead, but bogeyed 15, then parred his way in to make the playoff with Simon Khan and Matteo Manassero. At the first extra hole, Warren drove his tee shot into the trees on the right at 18 and had to go back to the tee.
After hitting his drive down the fairway, he then dumped his fourth shot into the water hazard.
He managed to get up and down for a double-bogey, but both Khan and Manassero made birdies to eliminate Warren. 1994 Doug Sanders World Boys Championship European Tour wins (3) Challenge Tour wins (2) Other wins (1) DNP = Did not play CUT = missed the half-way cut "T" = tied Yellow background for top-10.
