On 28 January 2010, Lowry agreed a deal which would take him on a loan to Leeds United until 13 March 2010, joining his fellow Australian international teammates Patrick Kisnorbo and Neil Kilkenny. He made his debut for Leeds against Colchester United, playing left back for Leeds. After an impressive debut, Lowry suffered a minor injury and had to be substituted and replaced by Bradley Johnson after 70 minutes. After missing the FA Cup replay against Tottenham Hotspur due to not being eligible, Lowry returned to the Leeds starting lineup in the following game against Hartlepool United.
Lowry missed the first three cuts of his professional career, but had his first payday on 5 July, when he finished 50th at the Open de France ALSTOM. He had his best professional result in November 2009, when he finished 3rd in the Dunlop Phoenix Tournament in Japan. In January 2010, Lowry finished in fourth place in the Abu Dhabi Golf Championship, moving him into the top-100 of the Official World Golf Ranking.

Lowry started for Leeds in the Football League Trophy Northern Area Final, second leg game against Carlisle United, in which the game was lost with Lowry missing the decisive penalty in sudden death in the penalty shootout. After the game it appeared as though Lowry was attacked by a set of Carlisle supporters who had invaded the pitch. After starting every game for Leeds Lowry was dropped from the Leeds squad for the match against Brentford after suffering an injury, before returning to Villa when his loan spell ended. On 25 March 2010 Lowry re-signed for Leeds for a second loan spell, with his loan lasting until the end of the season. Lowry started at left back for Leeds against Norwich City on his return to the club, a match Leeds went on to lose 1–0 in injury time. Lowry didn't overley impress the Leeds fans in his loan spell at Leeds, with him being mostly played out of position at Left back for the entire spell, he was substituted for Jonathan Howson in the final game of the season against Bristol Rovers with 1–0 down at the time, but his loan spell ended on a high as Leeds were promoted in 2nd place after scoring two goals to go on and beat Bristol Rovers and secure promotion to The Championship.
As for the workouts he’s doing, DeChambeau is continuing work he’s done with Greg Roskopf, whose system focuses on making people stronger where they are weak, particularly at extraneous points in their muscular system. In other words, there are likely points in the golf swing — in various golf movements — where DeChambeau isn’t as strong as he could be, hence the more work and weight. If he has already ascended to 220 in a matter of weeks, 230 should follow soon. Stay tuned.
DeChambeau made his PGA Tour debut as an amateur in June 2015 at the FedEx St. Jude Classic near Memphis, Tennessee, and finished in 45th place. He played in his first major championship at the U.S. Open at Chambers Bay, but missed the cut by four strokes. DeChambeau was unable to defend his NCAA title in 2016 after the SMU athletic department was handed a postseason ban by the NCAA. He decided to forgo his senior season to play in a number of events before turning professional. At the 2015 Australian Masters in November, DeChambeau was runner-up with John Senden and Andrew Evans, two shots behind the winner Peter Senior. He was the low amateur at the Masters in 2016 and tied for 21st place.
Hyundai Tournament of Champions: Finished T6 in a Monday-start-Tuesday-finish event, the season-opening, 54-hole Hyundai Tournament of Champions. The event "started" twice during the regularly scheduled first round Friday and later Sunday, but both times PGA TOUR rules staff halted play due to unplayable windy conditions and subsequently voided all scores that had taken place. As the first player off the tee, he ended up hitting three "opening" shots of the season.
