Carlow and Antrim played out a thriller in their Christy Ring Cup game at Dr Cullen Park, with the Saffrons prevailing by a point after extra time.
The Ulster side won out on a 3-20 to 2-22 scoreline.
An early goal from Marty Kavanagh saw Carlow build up a seven-point advantage by the 20th minute of normal time. However, their lead was only four at the break, with Niall McKenna raising a green flag for the visitors.
Carlow looked on course for victory when leading 2-16 to 2-12 as the game entered the final few minutes. However, three points from Neil McManus and one from Paul Shiels brought the Saffrons level and the requirement for extra time.
The home side started the additional period well and went four clear again. However, a McManus goal tied things up again. It was Antrim who finished the stronger, with the Cushendall player, who scored a tally of 1-13 and Paul Shiels getting the scores that saw them win by the bare minimum.

The visitors were in control for most of the game and were leading by five points at the midway point of the second half. However, a goal by Eoghan Sands on 58 minutes was the catalyst for a Down surge that eventually yielded a seven-point success.
