Boston United returned to winning ways in a crazy afternoon which saw two Colwyn Bay players red carded.
Spencer Weir-Daley and Carl Piergianni were the matchwinners, in an afternoon where the post and keeper Chris Sanna prevented the hosts adding more strikes to their goals tally.
Dennis Greene handed a debut to keeper Lewis King, with Sam Vince named on the bench and question marks raised over the future of Ashley Timms, who made two high-profile errors during last week’s 3-2 defeat at Brackley Town.
King, a former Stockport County and Eastwood Town player, became the third man to go between the sticks for the Pilgrims in the space of two games, while Liam Marrs - on loan from Sunderland - made his home debut at right back.
Wearing the Bay’s number one jersey was Sanna, who netted a freak goal during his side’s 3-1 victory at home to Solihull Moors seven days earlier.
That result was just the Seagulls’ third victory of the Skrill North campaign, but wins one and two both came on the road.
And the Bay began in confident mood, almost taking the lead within four minutes.
Boston’s marking was sloppy and Marc Williams was granted a free header from Michael Lea’s corner, but his effort smashed against King’s post.
Seconds later and Piergianni had to be alert to takie the ball off the feet of Williams as he looked to pull the trigger from just six yards out.
United’s first chance fell to Rene Steer, but the left back’s shot from distance was always curling away from goal.
And as Boston enjoyed their first spell of real pressure, Scott Garner saw a header saved by Sanna before Marc Newsham and Ian Ross both had efforts that failed to hit the target.
But two minutes before the interval, Colwyn took the lead from the penalty spot.
King was quick off his line to try to claim a loose ball, but Gareth Evans got there first and was tripped by the United keeper.
After King was booked for remonstrating with referee Michael George he was picking the ball out of his net, Jonathan Royle’s low strike evading his dive.
Moments after the interval Boston created a great chance, but as Ricky Miller charged down on goal his effort was blocked by the legs of Sanna.
And then suddenly the contest swung massively in United’s favour.
In the 56th minute Bay right back Danny Taylor was dismissed for his second booking in the space of three minutes.
After kicking the ball away he received his second yellow for taking a free kick too quickly and was needlessly taking an early bath.
Spencer Weir-Daley drew Boston level in the 59th minute with a casual and cool side-foot at the back post after Steer’s cross was defelcted into his path.
In the build-up to that goal, Piergianni saw a header expertly saved by Sanna.
The Pilgrims almost took the lead when Conor Marshall’s powerful run teed up Newsham, but the forward’s effort was deflected on to Sanna’s post.
Boston were now dominating the game but a rare Colwyn effort saw Evans’ volley fly across the face of goal.
With 12 minutes to go, Tom Smyth became the second Seagull to see red after a clumy charge on Miller saw him collect his second booking.
And from the resultant free kick, Piergianni headed Boston in front.
Steer dummied the dead ball before Newsham teed up Ross. The captain’s reverse cross met Piergianni at the back post and he looped his effort over the stranded Sanna.
Further remonstrations saw Colwyn coach Ade Akinbiyi sent to the stands as the day went from crazy to absolute bonkers.
There was still time for Miller to hit the foot of Sanna’s post following a trademark mazy run, but as the five minutes of time added on came to an end it was Boston who claimed all three points.
