In 2007 Dublin qualified for a third consecutive Leinster under-21 final. Offaly were the opponents on this occasion, as McCrabbe hoped to claim a winners' medal at the third attempt. 'The Dubs' finally broke through and a 2-18 to 3-9 defeat of Offaly gave McCrabbe a Leinster under-21 winners' medal at last. It was Dublin's first title in that grade since 1972. A subsequent defeat of Cork allowed Dublin to advance to an All-Ireland final meeting with Galway. The westerners got off to a dream start and took an early lead. At the long whistle McCrabbe's side were disappointingly defeated by 5-11 to 0-12. This was his last outing with the Dublin under-21 hurlers.
