It was a performance full of promise, but unfortunately it was unable to provide Pompey with all three points.
Aiden O’Brien had slotted them into the lead early in the second half at Bolton and the visitors looked to be in control.
But referee Marc Edwards decided that Hayden Carter’s challenge on Elias Kachunga warranted a penalty and Kieran Sadlier stepped up to convert it.
Danny Cowley was pleased with their overall display from his men, although conceded that they lacked a clinical edge.
The Blues boss said: “We’re disappointed not to win the game because I felt that we’d done enough to do so.
“It was a really good away performance from us – apart from not being ruthless enough with our final action.
“Either a poor decision or lack of technical execution has probably stopped us from collecting all three points.
“After going 1-0 up we were creating chances and looking a threat every time we went forward, but we need to go for the throat in those moments.
"It was a really good away performance from us – apart from not being ruthless enough with our final action."
“We had Bolton in a good place and weren’t clinical enough, while their goal then came against the run of play.
“I saw a lot of positive things in our performance – we pressed aggressively and upset Bolton’s rhythm and we just needed some more conviction.
“We set out to win the game and while it’s disappointing not to do that, I was pleased with the process.
“We’re a team that’s growing and if you can take away the frustration of not getting all three points, there was a lot to like.”
Cowley felt that a couple of key decisions went against his side, including for the Wanderers equaliser.
He said: “I thought Kachunga bought the penalty and you could see that the way he fell wasn’t natural, so we were disappointed that it went against us.
“There was a good shout for a handball from a Michael Jacobs shot as well, but we can only focus on what we can control.”
