Moisander goal gives Finland win over Wales
Wales came close to equalising in injury time when Finnish defender Sami Hyypia misjudged the ball and left David Edwards alone in the box, but keeper Jussi Jaaskelainen saved Edwards's low drive to preserve the win.
Finland carried the play for most of the game, opening the scoring in the fifth minute when Roni Porokara slotted a rebound past Welsh keeper Wayne Hennessey.
Wales evened the score 12 minutes later. Gareth Bale's long pass found David Vaughan alone down the wing, and Vaughan's cross was knocked past Jaaskelainen by a charging Craig Bellamy.
Finland now have 17 points and play at group leaders Germany on Wednesday in their final qualifier. Wales, fourth in the group with nine points, play their final game in Liechtenstein on Wednesday.
