Railway Union produced the surprise result of the season so far as their developing side handed Three Rock their first league defeat since the 4-1 turnover by Pembroke in October 2007.
Paul O'Brien opened the scoring with a deflection before Rovers' defence was caught cold as O'Brien took a quick sideline ball through to Eoin McArthur who slipped the ball under Shane Davey.
Kevin O'Brien then hit the bar and also spurned a one-on-one chance before Rovers came back in the second half - Michael Maguire getting one back from a corner variation - but missed a chance for a point when Garry Ringwood put a stroke wide, ruining Andy McConnell's return to first team action.
Monkstown 1 (Alec Barrett) YMCA 1 (Will Powderly)
Will Powderly's late goal from a slipped short corner secured a point for YM, their first on the road this term. Alec Barrett opened the scoring in the first half, finishing off a counter-attack afte exchanging a one-two with Gareth Watkins.
The improving YM, though, fought back and scored from a third of a series of corners - the first blocked down, the second saved by Dave Fitzgerald but the third was slipped to pusher-out Powderly who made no mistake to take a deserved draw. Monkstown were the only one of the three IHL teams due to play on Sunday to get a point.
Corinthian 5 (Brian Doherty, Sam Lopsey, David Carson, Miles Warren, D Kimfley) Fingal 3 (Mick McGuinness 2, David Bane)
Corinthian reversed their opening day 5-3 defeat with Fingal with one of their own in a thriller at Whitechurch Park.
Mick McGuinness scored a drag-flick for 1-0 but Corinthian fought back for a 2-1 and 3-2 lead thanks to Brian Doherty, Sam Lopsey and David Carson before Fingal pegged them back by half-time to 3-3. But the reds got the decisive second half goals and, with a couple of results going their way, take a big chunk out of the difference between themselves and the top five.
Kilkenny 3 (Tom Manning 2, Gary Sharman) Glenanne 4 (Shane O'Donoghue 2, David Keogh, David Shaw)
Glenanne raced into a 3-0 lead but found themselves subject to a second-half fightback from the Cats. The Glens, though, survived and move into the top two for the first time since early October despite the absence of Stephen Butler and Graham Shaw, rested due to the 14-game rule as well as Joe Brennan for work reasons.
The Leinster branch earlier this week raised the 14-game issue with the IHA, citing the fact that clubs have to rest players for their domestic league which acts as a qualifier for the IHL. The ruling, though, still stands meaning Pembroke, Three Rock and Glenanne will have to rest their stars for at least four league games and some or all of the cups. The rule, though, has been relaxed for goalkeepers.
It is the second time this season Kilkenny have provided a scare for the Glens but youngsters Shane O'Donoghue and David Keogh stepped into the breach.
