He turned professional in 2000, after playing college golf for Auburn University.
Dufner was a walk-on at Auburn University, where he won three times in his college career and was an Honorable Mention All-American in 1997. He graduated from Auburn in 2000 with a degree in economics.
In 1998, Dufner played in the finals of the U.S. Amateur Public Links at Torrey Pines, falling to Trevor Immelman, 3 and 2.
In his early career, Dufner struggled to hold down a place on the PGA Tour. He was a member of the PGA Tour in 2004 and the Nationwide Tour in 2001, 2002, 2003, 2005 and 2006. Dufner won two events during his time on the Nationwide Tour, the Buy.com Wichita Open in 2001 and the LaSalle Bank Open in 2006. He finished in 8th place on the Nationwide Tour money list in 2006 to earn his PGA Tour card for 2007. He finished 127th in the FedEx Cup standings in 2007, and failed to qualify at the PGA Tour Q-School, where he finished T149. He retained conditional status for the 2008 PGA Tour season, and then finished T11 at the Q-School that year to earn his card for 2009. He has been a member of the PGA Tour every year since. In 2009, Dufner finished in the top-10 on six occasions, including a third-place finish at the RBC Canadian Open, and a runner up place at the Deutsche Bank Championship, part of the FedEx Cup playoffs. As a result, Dufner went on to finish the year 11th in the FedEx Cup standings and 33rd on the year's money list.
Early in 2011, Dufner had a chance to win his first PGA Tour title at the Waste Management Phoenix Open at TPC Scottsdale when he finished tied for the lead at 18-under-par after 72 holes, before eventually losing in a playoff to Mark Wilson. Wilson made a birdie on the second extra hole and the best Dufner could manage there was a par. He also had a good finish in the Zurich Classic of New Orleans where a final-round 66 boosted him to a tie for third place. Dufner earned entry into the 2011 U.S. Open after Anders Hansen withdrew; previously during a qualifying tournament in Georgia, Dufner had lost in a playoff to Russell Henley. He also played in the 2011 Open Championship as a result of Tiger Woods pulling out due to injury. He missed the cut in both the U.S. Open and the Open Championship.
At the 2011 PGA Championship in Atlanta, Dufner was in contention to win his first major and maiden PGA Tour title, when he entered the final round in the last group and tied for the lead with Brendan Steele at seven under par. Dufner completed the front nine in 33, two under par, while playing partner Steele dropped four shots early on and fell out of contention. Dufner held the lead for most of the final round and was bogey-free through 14 holes. After his nearest challenger, Keegan Bradley, made triple bogey on the 15th, Dufner had a five-stroke advantage with four holes to play. Dufner then hit his tee shot on 15 into the water hazard right of the green on the par three. He got up and down from the drop zone to make bogey, but followed this with bogeys at 16 and 17. Meanwhile, Bradley scored back-to-back birdies on 16 and 17 to take the clubhouse lead at eight under, wiping out Dufner's advantage. Dufner parred the 18th and the two American players went into a three-hole aggregate playoff.
Dufner continued his good form in 2012 by sharing the 36-hole lead at the Masters, but faded on the weekend to finish T24. Three weeks later at the Zurich Classic of New Orleans, Dufner won for the first time on the PGA Tour in his 164th start when he defeated Ernie Els on the second hole of a sudden death playoff. He entered the final round with a two stroke advantage and shot a 70 to finish at 19 under par, a tournament total record, which Els also equalled. At the first playoff hole, the 18th, Els had a chance to clinch victory with a six-foot putt, but pushed it out to the right. Replaying the 18th again, Dufner found the green in two and when Els couldn't get up and down from 100 yards short of the green, Dufner sealed the win with a two putt. Dufner moved into the world's top 20 as a result of his first victory.
Three weeks later Dufner chalked up his second victory with a win at the HP Byron Nelson Championship by one stroke over Dicky Pride, who was seeking his first win since 1994. Dufner began the final round with the 54-hole lead, but suffered setbacks when he bogeyed two and three to surrender the lead. He recovered with birdies at four, five and seven, but remained behind playing partner J. J. Henry until the 17th when Henry made double bogey. Now tied for the lead with Pride, the clubhouse leader, after 71 holes, Dufner sank a 25-foot birdie putt on the 72nd hole for the outright victory. The win elevated Dufner to 14th in the OWGR and first in the FedEx Cup standings. Dufner became only the second multiple winner on the PGA Tour in 2012, alongside Hunter Mahan.
In May 2012, Dufner had an opportunity to win his third PGA Tour title of the year at the Colonial, where he was leading after 36 and 54 holes respectively before being beaten by one stroke by former Masters champion Zach Johnson. The second-place finish, however, catapulted Dufner to 8th place in the Official World Golf Ranking, a career best ranking at the time.
Dufner qualified for his first Ryder Cup team in 2012, finishing with a record of 3–1 in the three day matches, including a 2-up win over Peter Hanson in the singles competition.
On May 5, 2012, Dufner married his girlfriend Amanda Boyd, whom he had met in 2009 through mutual friends at Auburn. They were divorced in early 2015.
In January 2013, Dufner stated an interest in taking up a membership with the European Tour.
In June 2013, Dufner finished fourth at the U.S. Open at Merion Golf Club, the second year in a row finishing fourth at the tournament. Dufner entered the final round at +8, but birdied five of the first 14 holes to pull to +3 overall. However, he triple-bogeyed the par-4 15th hole to move back to +6. After a birdie at 16, Dufner scored par on holes 17 and 18 to finish the tournament at +5, four shots behind the leader, Justin Rose.
Dufner's laid-back mannerisms have led to the term "Dufnering," which specifically refers to a slumped sitting position with an expressionless face. The term originated in March 2013 after a photo went public of Dufner slumping without expression while visiting a youth center in Irving, Texas. Afterward, Keegan Bradley and several other professional golfers good-naturedly mocked Dufner through Twitter and other social media, and "Dufnering" rapidly became a popular phenomenon.
In January 2016, Dufner won his fourth PGA Tour title at the CareerBuilder Challenge at PGA West. This ended a 2 ⁄2-year winless drought since his 2013 PGA Championship victory. He defeated David Lingmerth in a sudden-death playoff after both players finished four shots clear of the field at 25-under-par. Lingmerth had a chance to win on the first playoff hole, but could not hole his birdie putt from 20 feet and Dufner had to hole a 10-foot putt for par, meaning the players returned to the 18th for the second extra hole. After finding the light rough with his tee shot, Lingmerth hooked his second shot into the water on the left, allowing Dufner to comfortably finish the hole and take the title.
On June 4, 2017, Dufner won the Memorial Tournament.
In November 2017, Dufner got into a Twitter dispute with Golf Channel analyst Brandel Chamblee after Chamblee had reportedly offended Dufner's swing coach Chuck Cook. Chamblee ended up blocking the major champion due to his use of profanities.
In the 2018 PGA Tour season, Dufner did not win a tournament. He won $1,497,655 and finished 80th on the money list.
Jason married Amanda Boyd on May 5, 2012. The couple announced their separation in 2015.
Currently, Jason Dufner is 43 years old. Jason Dufner will celebrate 44th birthday on Wednesday, March 24, 2021. Below we countdown to Jason Dufner upcoming birthday.
