Preseason soccer can be funny sometimes.

Some teams play full strength lineups while some teams mix it up and the matchups in preseason games can create some mismatches with teams having different priorities in mind. Wednesday was one of those examples.

The Chicago Fire blitzed the Montreal Impact with a goal in the first 30 seconds and three in the first 20 minutes of a 4-1 win in St. Petersburg, Fla. The Fire played what appeared to be a full strength lineup for just over 60 minutes, with most starters going more than 70 minutes, while the Impact had a combination of starters, reserves and academy players in both halves.

The Fire got on the board 25 seconds in when Michael de Leeuw caused a turnover in the Montreal box. He set up David Accam for an easy finish.

Dax McCarty made it 2-0 in the 15th minute with a wicked half-volley on a layoff from Nemanja Nikolic. Accam stole the ball in Montreal's defensive third and centered to Nikolic.

Three minutes later an own goal made it 3-0. All three of the early goals came as a result of mistakes by Montreal which the Fire capitalized on.

In the second half Nikolic got a goal of his own by sliding in to finish of a de Leeuw ball that looked like a shot following a short corner.

Montreal got one back in the final minutes when an Ignacio Piatti shot hit the arm of Drew Conner for a handball in the box. Piatti then converted the penalty.

The Fire lined up in coach Veljko Paunovic's standard 4-2-3-1 formation. Goalkeeper Jorge Bava played the full 90 minutes and made a few notable saves. All the Fire's field players were subbed off in the second half.

Michael Harrington got the start at right back, a position which remains a question mark. Harrington and Johan Kappelhof are the only players on the roster with notable experience playing right back and Kappelhof is also probably the Fire's best centerback. Harrington was subbed off in the 71st minute and Kappelhof, who started the match at centerback, played the next 12 minutes at right back before Joey Calistri, typically a midfielder or forward, replaced him.

The Fire had two right back trialists in camp in Drew Beckie and Boyd Okwuonu, but neither made the return trip to Florida after the Fire returned to Chicago over the weekend. Second round pick Guillermo Delgado, a forward, is also no longer in camp with the team.
