Man-of-the-match Jason Koumas admitted Wales were disappointed not to have scored more goals in Wednesday's Euro 2008 win over San Marino.
Koumas' casual penalty was almost saved by the San Marino 'keeper
"The performance was OK but we were a bit sloppy at times and we could have scored six or seven goals," said Koumas after the 3-0 win in Cardiff.
"We scored the early goals we wanted but didn't follow it up with more.
"We're happy to take the three points though, and hopefully this will help our campaign get started again."
Koumas scored Wales' third and final goal midway through the second half from the penalty spot after first-half Ryan Giggs and Gareth Bale efforts.
At least we were back to the game we are trying to develop
Wales manager John Toshack
But the West Brom midfielder almost threw away the chance as his casual chip was partially saved by goalkeeper Aldo Junior Simoncini before trickling over the line.
"I was quite lucky," said Koumas, who had hit the San Marino crossbar with a sublime chip in the first half.
"I changed my mind as I ran up to take it but luckily enough it went underneath the goalkeeper and into the goal, so I was delighted."
The result lifts Wales above Cyprus into fifth place in Group D, although they remain seven points off a qualification place.
Manager John Toshack said he was delighted to secure a victory after Saturday's dismal defeat to the Republic of Ireland, but stressed the performance was a difficult one to judge against such poor opposition.
"At least we were back to the game we are trying to develop," said Toshack. "We lost it completely in Dublin, so a win is a win.
"It's difficult to talk about improvement because there is such a difference in playing Ireland away and San Marino at home.
"We're happy with the result but it still doesn't make up for the result on Saturday.
"Up until that game we had been going well - even in the Slovakia game we lost at home we played the way I wanted.
"We just have to look at the Czech Republic game now on 2 June because it's a game we have to win otherwise it will be goodnight for this campaign."
