There were some high-scoring clashes in the opening round of the Christy Ring Cup, with London, Wicklow, Down and Kildare all coming away with victories.
Meanwhile, there were three fixtures down for decision as the Nicky Rackard Cup also got underway this weekend. Warwickshire were too strong for Louth, while Donegal and Monaghan also prevailed in their respective ties.
Derry rallied to edge out London following a two-point win in Ballinascreen. They were seven points down at the break but posted 1-10 after the restart to secure the win.
A Seanie Germaine goal proved to be a vital score in Wicklow's victory over Mayo. The home side built up a seven-point lead shortly before the half-hour mark, with the concession of a goal making it a five-point gap at the interval.
The Garden County survived that setback and regained control in the second half with Germaine's goal strengthening their advantage. Mayo did score a second goal in additional time through Eanna Ryan, but it was too late as Wicklow secured the win.
Down encountered few problems as they put six goals past Armagh to record a 28-point win, while Kildare inflicted a similar defeat on Roscommon, winning on a scoreline of 4-26 1-09.
Warwickshire enjoyed a routine win over Louth, coming away from Dowdallshill with a nine-point victory. The teams were locked at 1-9 apiece at the break, but Warwickshire rattled off two goals to push themselves ahead, only for Louth to respond with two points during that period.
Louth were awarded a penalty in the second half but failed to convert the opportunity as Warwickshire added a third goal before the end to put the contest beyond doubt and get their campaign off to a winning start.
Donegal made a strong start to their tie against Tyrone through a Davin Flynn goal to open their account. Tyrone levelled proceedings with a Chris Kearns point in the ninth minute.
Flynn was to the fore again later in the first half as his point put Donegal six points clear of Tyrone at half-time.
The home side couldn't curtail that gap after the restart as Donegal extended their lead to 10 points through a Declan Coulter point.
Damian Casey tapped over a few scores for Tyrone in the closing stages, but it was an emphatic victory for Donegal in the end.
Eamonn Collins helped Monaghan to establish a four-point lead over Longford inside the first six minutes of their meeting in Inniskeen.
The sides traded scores thereafter and Longford's efforts to cut through the deficit were rewarded with a goal for Joe O'Brien to trail by seven at the break.
The visitors closed in further on their opponents in the early minutes of the second half, as O'Brien found the net a second time.
But Monaghan reclaimed the initiative on 47 minutes following a goal from Mark Treanor and further goals from Brian McGuigan and Tadhg Campbell pushed Monaghan into an unassailable lead before the end.
