Lowry's ex-Leinster coach wants to see world number 19 have a stellar 2023.
Shane Lowry's former coach believes he should be looking to break into the world's top ten and challenge for majors regularly.
The 2019 Open Champion delivered a flawless run of three rounds without a bogey on his way to winning the BMW PGA Championship.
Lowry pipped world number 6 John Rahm and Fed EX cup Champion Rory McIlroy to the DR World Tour's flagship prize.
Donagh McArdle was Lowry's coach when the Clara man represented Leinster and he says the sky should be the limit next year:
