Veteran players James Ryan and Gavin O'Mahony retired from inter-county hurling within days of each other at the end of the previous season, while 2017 championship panellist Stephen Cahill was also an absentee.
[1][2] Notable players returning included Kevin Downes, who missed the 2017 season due to a cruciate injury, and David Reidy, who rejoined the Limerick panel after a year with the Kildare senior hurling team.
Other additions included several players from Limerick's 2017 All-Ireland Under-21 Championship-winning team, such as Séamus Flanagan.
[4] Leading by nine points at one stage in the second half and by eight with just two minutes of normal time remaining, Limerick withstood a sensational Galway comeback, which included late goals by Conor Whelan and Joe Canning, to win by a single point.
Limerick were described as the "worthiest All-Ireland champions" of all time after playing eight games to win the title, including defeats of the traditional big three - Kilkenny, Cork and Tipperary - as well as the 2017 All-Ireland champions Galway and runners-up Waterford.
