TORONTO — The length of the schedule demands improvisation. The Rockies awoke Wednesday underneath the dome, feeling like they were crawling from underneath a rock. They needed a burst of sunlight. Or a jolt. But apparently that will have to wait until Roy Oswalt's first start. Juan Nicasio wore a different number, but his ordinary performance was exactly what the Rockies weren't looking for in the series finale against the Blue Jays. He worked five innings or less for the ninth time in 16 starts, the part-time show hardly the antidote for a lineup that suddenly can't hit. The Jays broomed the Rockies 5-2 in a series that was as one-sided as any since the Giants had their way with them in April. Colorado never led in three games, falling to a chilling 3-10 against American League opponents this season.
