Exeter boss Gary Caldwell was delighted after his side secured a 3-0 victory over Shrewsbury to move 10 points clear of the League One relegation zone.
Shrewsbury were dealt a blow in the seventh minute when referee David Rock showed a red card to winger Jordan Shipley for a two-footed challenge on Ryan Woods.
And the Grecians took full advantage with Will Aimson, Luke Harris and Jack Aitchison all scoring before half-time to secure a first win in six games.
Grecians boss Caldwell said: “I was delighted. The red card changed the game, and it actually made it harder in some respects.
“In terms of how deep Shrewsbury then sat in, it could have potentially been a really long night.
“When we created opportunities, we were ruthless with our finishing, and our goals were fantastic.
“I thought, in the second half again, we could be a bit better in our final third play, take a bit more risk, and create more opportunities.
“The size of the game and where we both are in the league, I can’t be happier about what the players did and the result.
“When we went into tight areas and played intricate football in and around the box I thought we played we were very good.
“I just said to the players there is eight games to go they are all massive games and we want to win as many points as we can.”
Shrewsbury are three points worse off than Exeter following their third defeat in four outings.
Boss Paul Hurst was furious with the decision to send off Shipley.
“I can’t say what I really think,” Hurst said.
“I think we may as well stop playing football if that’s a red card.
“I am not saying it’s not a red card for Woods at all – but if anything, he is the one that ends up higher on Shipley.
“When the referee blew up, I thought he gave a free-kick to us. And my gut from the side is that honestly – and admittedly, I was a distance away – but it was Woods who was slightly late on it, and Shipley got there first.
“Then for the red card I was genuinely thinking it was for their player and for it to turn out for Jordan was baffling.
“It spoils the night for everyone and at 10 men we need to give it a go. But like I said they are good in possession and that is the type of team you don’t want to go down to 10 men to.”
