James Morrison also forced an excellent save out of the Finnish keeper with a long range curling effort that was palmed away with one-hand as it headed for the top corner.
There were guilt-edged chances for both sides in the second half, but a combination of bad finishing and two goalkeepers in inspired form kept the scoreline blank.
The Baggies came the closest to a winning goal - Kim's 30-yard strike hitting the underside of the bar and then Ishmael Miller headed the rebound straight at Jaaskelainen.
Bolton also had their chances to break the deadlock. Substitute Riga saw a free kick saved well by Scott Carson, while Kevin Davies had two goals disallowed.
