Steve Thompson spoke of his disappointment once again as The Seasiders were on the wrong end of a 2-1 scoreline for the third time in four matches as Barnsley snatched all three points from Bloomfield Road, thanks to Jason Scotland's 88th minute goal.
Blackpool started well but found themselves behind when Jim O'Brien found himself on the end of a quick breakaway to place the ball past Matt Gilks.
Tommo's side grabbed the equaliser after an explosive start to the second-half when Thomas Ince struck on 55 minutes. They then went on to dominate until Gilks saw red for handling outside the area and Pool were forced to play the last 25 minutes with ten men.
"I'm running out of things to say to the lads now," said Tommo.
"I couldn't have asked for anymore, their effort and work-rate was fantastic. The disappointing thing is that their first goal comes from our corner and they've gone the length of the pitch."
The sending off forced Thompson's hand as he brought Mark Halstead on for Matt Phillips, but it came at a time when The Seasiders were on top.
"From the sending off we changed our shape and tried to stay in the game but even then we created chances. Derbyshire hit the bar with a great shot and there were crosses going in the box. Considering what we are playing on I still think we play decent football on it.
"It's always going to be difficult when you lose your keeper. I had to sacrifice Matt Phillips for Mark to come on so we had re-adjust and change our tactics a little bit. We went 4-4-1 and tried to use Derbyshire's energy in the channels and get up there and support him."
Tommo believes that Blackpool will soon get a change of fortune but admits they have got to earn it by cutting out any mistakes.
"It's just another big disappointment to lose such a sloppy goal. It's silly errors that are costing us at the moment.
"I've got a lot of disappointed players in there that I've got to lift up again, and I will do.
"Incey has chipped in with a goal again and we've got to look to get goals from other departments and that's why I was encouraging the midfielders to get into the box and get on the end of crosses."
