Shrewsbury fell to a narrow 2-1 defeat at Barnsley.
In what was an even encounter at Oakwell, Nicky Cadden and Devante Cole put the hosts two goals up in the first half.
Cadden then received his marching orders for a nasty foul on Killian Phillips in the 75th minute.
Despite being two goals down, Town fought and fought to get themselves back into the game - and they did pull a goal back in the 90th minute thanks to an excellent Phillips header.
Then just moments later, we had a glorious chance to equalise when the ball broke for Ryan Bowman just outside the six-yard box but his low strike was saved by goalkeeper Harry Isted.
The drama didn't end there as Bowman also received a red card in the dying minutes of the game.
Manager Steve Cotterill opted for a 3-5-2 system for the trip to South Yorkshire, with Ryan Bowman and Rob Street the front two.
After picking up an injury in the 18th minute against Peterborough on Good Friday, Christian Saydee was not fit enough to be in the matchday squad, with Street taking his place up top.
After serving a one-game suspension, Tom Flanagan was brought back into the heart of defence alongside Matt Pennington and Chey Dunkley.
Carl Winchester and skipper Luke Leahy accompanied Killian Phillips in the middle of the park.
Michael Duff's Barnsley side also went with a 3-5-2 formation with Cole and Max Watters leading the line.
In what was an entertaining and even opening 20 minutes, both teams had chances to break the deadlock.
It was Barnsley who threatened first through Adam Phillips as he whipped a cross into the middle of the box.
But Marosi was quick to see the danger and rise highest to punch the ball clear ahead of the waiting Herbie Kane.
Two minutes later, it was Town on the attack when Leahy sent a clever pass forward which Bowman collected.
He then carried the ball into the box before hitting a low drive that Isted got down and saved well at his near post.
On 10 minutes, Watters twisted and turned in the box before getting a shot away, but Marosi got down quickly to claim.
A few minutes later, Kane received the ball in the middle of the park before driving forward and playing it out to Adam Phillips.
The midfielder drilled a low cross toward Cole, who flicked it toward the goal from close range, but Marosi once again got down and claimed well.
Shrewsbury responded with Leahy whipping in a dangerous free-kick just past the half-hour mark.
That was met by Flanagan but his powerful header was well held by Isted.
Barnsley threatened again in the 36th minute when Cole teed up Phillips in the box. Marosi, though, again read the danger with the keeper getting down to make a smart stop.
It had been an even and keenly contested first 40 minutes.
But Barnsley then went on to score twice before the break. First Cadden sent in a low cross that went through a crowd of bodies and into the net.
Then just moments later, Liam Kitching hit a powerful drive from distance that Marosi parried away. But the ball then fell kindly for Cole who tapped in from close range.
Town made a change at the break with Elliott Bennett replacing Winchester.
The change saw Town switch to a 4-2-3-1 formation, with Moore stepping forward into a defensive midfield role alongside Leahy.
Street moved out to the right whilst Bennett occupied the left wing, and Killian Phillips was just behind Bowman in the number 10 role.
Town began the second half brightly and had a huge chance for a penalty waved away by referee Geoff Eltringham in the 55th minute when Killian Phillips was clattered by Kitching in the box.
The defender appeared to head Phillips instead of the ball, with Shrewsbury's players adamant they should have had a spot kick.
Barnsley played a long ball over the top that reached Watters just past the hour mark.
The forward took a touch and flicked it over Marosi but, with the ball destined to creep over the line, Flanagan sprinted back and cleared it out of play.
Cadden was shown red for a late challenge on Killian Phillips in the 75th minute.
From that point on, Town pressed and pressed to find a way back into the game.
And we did pull a goal back just past the 90-minute mark, with Shipley sending in a brilliant cross that Killian Phillips planted into the top corner with an even better header.
Town then had a glorious chance to pull level just moments later when a cross into the box was met by Bowman.
But the forward sent a low strike straight at Istead. Just moments later Bowman was then sent off after picking up a second yellow card.
Despite a spirited performance, Town were unable to pull level in the game and suffered defeat on the road.
