Kerry and Carlow continued their unbeaten starts to Division 2A of the Allianz Hurling League, while London worked hard to claim a home win over Kildare in Ruislip.
Kerry stay on top Division 2A by virtue of scoring difference after claiming a hard-earned 3-13 to 2-15 win over Westmeath at Cusack Park, Mullingar.
It was a late goal from substitute Padraig O'Connor which secured a dramatic one-point win for the visitors.
Kerry started well early on with a brace of Mickey Boyle points, but Westmeath drew level thanks to scores from Alan McGrath and Derek McNicholas.
Westmeath led by 1-08 to 0-07 at the break, finishing the half with five unanswered scores.
Both sides had periods of dominance on the restart, but O'Connor certainly made his mark, firing 2-02 in the second half.
O'Connor's second goal on the stroke of the 70th minute handed Kerry a one-point lead, but Westmeath had two late chances of an equaliser.
McNicholas blazed a goal shot wide, and although he won a free from the resulting puck-out 35 metres from the Kerry goal-mouth, he failed to capitalise as the visitors held out for victory.
Derry failed to claim back-to-back wins as Carlow always looked in control in their 2-20 to 0-12 home win at Dr Cullen Park.
John Meyler's charges led by 1-11 to 0-06 at half-time, with Mark Brennan netting their goal after just four minutes.
The hosts failed to yield in the second half, and continued to stay on top, with a 45th-minute goal from Sean Murphy (1-05) laying the platform for a 14-point win.
London staged a magnificent second-half turnaround to deliver a 1-21 to 0-18 win over Kildare at Ruislip.
Despite a long trip, the visitors failed to show any signs of jet-lag early on and held a 0-13 to 0-09 interval lead.
Kildare continued to edge the lead by 0-16 to 0-15 entering the final quarter, but could only manage two further points as the Exiles finished strongly.
London’s only goal arrived in the 58th minute to hand then a 1-15 to 0-17 lead, and they stayed ahead until the finish to register a hard-earned six-point win.
