A breakaway goal from Leon Osman 17 minutes from time settled it and left Tomkins - and the rest of his team - cursing their luck.
He told whufc.com: "When we got back into the game and made it 1-1, we looked the stronger team so we're disappointed to lose it in the end.
"The lads gave it all they had and towards the end we tried to play off Andy. We showed a good effort and on most days we would have gone on from making it 1-1 to winning the game.
"It wasn't to be and it's a hard one to take."
