Moloney buried an Eoghan McPartland flick-on [70th] to cancel out Aleko Katiras’ strike for the Greeks ten minutes earlier.
Samos went ahead after the Rocks’ Paul Bradshaw had his penalty shot saved [55th].
“Tough enough game — first against second – I can’t be disappointed,” said Shamrock coach Robbie Walsh.
He lauded the team’s effort, singling out McPartland for Man of the Match honors.
The once-beaten Rocks [9-1-2, 29] saw their lead at the top cut from nine points to seven after Mr. Dennehy’s fourth straight victory, 3-0 at the expense of Hoboken FC, lifted them into second place [6-2-4, 22]. Samos [5-2-5, 20] dropped to third.
On Randalls Island, Shamrock’s Over-30s ended a two-game skid with an impressive 1-1 draw with Div. Two leaders Tesoro. This, after Tesoro’s Lincoln Garcia [40th] pegged back Onder Koksol’s opener for the Irishmen.
“We created chances in the second half but couldn’t score,” said Eoin Sweeney whose side finished with ten men after Mario Angelucci’s ejection [75th] for dissent.
Garcia’s leveler aside, Shamrock’s backline held firm.
“Joe Connolly was exceptional in central defense, Paddy McGarry at right fullback, sweeper Randall Freedman was Man of the Match and Paudie Moloney in goals did well,” said Sweeney, who played left fullback himself.
Shamrock improved to 7-5-1  in mid-table.
Lansdowne Bhoys blanked Barnstonworth Rovers 2-0 at Tibbets Brook Park to make it two wins out of three in as many weeks.
First half goals by Kurt Smith [25th] and Damian Mescall, who fired in a 20-yard free kick [37th] saw off Rovers.
Lansdowne were on the rack in the second half but despite losing center half James Pounder to injury, managed to hold on for the win.
“We played very well, but it’s not enough. You need to make chances count,” said Rovers coach Stavros Zomopoulos, who was missing star forward Steve Pugliese.
“People kept their composure,” said Bhoys president Izhar Harpaz, whose lads rebounded from a 3-1 loss to New York Athletic Club [NYAC].
Lansdowne [7-5-1, 22] had hammered NYAC 3-0 on March 22.
