The San Jose Earthquakes picked up their first win of the preseason Wednesday with a 2-0 victory over the Chicago Fire in an 80-minute match at the IMG Academy in Bradenton, Fla. The defeat is the Fire's first of the preseason.Midfielder Brad Davis, acquired from FC Dallas in a draft-day trade, opened the scoring in the 13th minute, slotting home a pass from forward Alejandro Moreno, who was obtained by the Quakes in an early January trade with the Los Angeles Galaxy. Just minutes earlier, Davis had threatened with a run through the Fire defense, but he was tackled before he was able to unleash a shot. Late in the second half, forward Roger Levesque, who came on for Ronald Cerritos at the break, notched an insurance marker for the Bay Area club. Rookie Chris Wondolowski started the play on the left, sending a ball across the field to Brian Mullan in the right corner. Mullan then whipped in a cross that Levesque was able to knock past second-year Fire 'keeper Matt Pickens. Earlier in the second stanza, both Pickens and his opposite, Quakes 'keeper Pat Onstad made crucial saves for their clubs. Onstad held a close-range effort from Fire midfielder Hollis Davidson early in the second half, and Pickens later parried a Victor "Boomer" Arbelaez shot that, at the time, helped keep the game close. The Earthquakes are back on the field in Bradenton Thursday to take on the MetroStars. The Fire return to action in Bradenton on Saturday against the U.S. Under-20 national team.
