Grand Canyon men's golf head coach
Mark Mueller announced the signing of Irish golfer John William Burke and Arizona native Jack Langbein on National Signing Day, both of whom will join the program in the fall of 2027.
"As a coaching staff, we are very excited to add both Jack and John to the GCU golf family," Lopes head coach
Mark Mueller said. "Most importantly, both of these young men have high character and come from great families, and both have had great success on the golf course within the last year. We fully expect these two to keep getting better, and by September time, are ready to compete for a spot in the lineup and make this program better."
Burke, who is from Mayo, Ireland, joins GCU as one of the top youth golfers in his home country. Throughout his junior career, Burke has won 50 tournaments after starting his golf career at the age of 7.
In 2024, the Ballyhaunis Community School attendee was named the Golf Ireland Under-16 Order of Merit Champion, winning by 282 points. That same season, he climbed to No.1 in the U16 and U17 rankings.
As of this past year, Burke was No. 3 in the European U16 rankings and won the 2026 Irish Junior Open Elite/WAGR event. He also has experience representing his country, doing so more than 20 times at the U16, U18 and senior levels. Against England and Spain, he was unbeaten in six matches and helped Ireland to the Carris Trophy Nations Cup for the first time in 2026, securing promotion to Division 1 of the European Boys' Championship for 2027.
Langbein, an Arizona native and Brophy Prep student, finished as one of the top golfers in Arizona after the fall state championship at Aguila Golf Course. He has finished top 10 in three consecutive AIA Division I state championships, including a 5-under score for ninth place earlier this month.
He tied for seventh in 2025 and tied for 10th in 2024, helping Brophy win three consecutive state titles. Brophy ranked No. 1 nationally via PGA National High School Golf Association in the final 2025-26 rankings.
Individual rankings saw Langbein at No. 387 in the Rolex AJGA boys' rankings, with two AJGA top-10 finishes this year. In Arizona, the Phoenix native is ranked sixth with 11 top-10 finishes over the past 12 months.
Langbein is also a host and leading fundraiser for AJGA Arizona Cactus Cup, topping the fundraising leaderboard in 2025 and 2026 in support of the JGAA and AJGA ACE Grant.
