A massive second half turnaround saw Limerick maintain their 100 per cent record in Division One B as they crushed an Offaly side that couldn't build on their impressive first half showing.

Aided by a strong breeze, Offaly had the better of the opening period but Limerick outscored the home side 0-13 to 1-1 in the second half.

Graeme Mulcahy and Conor Allis were the shining lights in the attack on a day in which they could also afford 12 wides while still having four points to spare. Limerick added the desired tempo to finish the game strong and reach the Division 1B final with a game to spare.

Offaly got off to a lightening start while aided by a strong breeze and Shane Dooley had 2-3 to his name after 11 minutes as the home side led 2-3 to 0-1.

Limerick slowly edged their way back into the contest with Seamus Hickey pulling the strings at centre forward to bring them back to 2-7 to 0-8 at the break.

Kevin Downes came more into the game in the second half and with Mulcahy in the other corner leading the way, the Limerick men were back into the lead on 50 minutes through Mulcahy 2-7 to 0-14.

Colin Egan grabbed a goal for Offaly to end almost 30 minutes without a score before being sent off but Mulcahy and Allis steered John Allen's charges home.
