TORONTO – It is an undeniable and jarring shift and to survive in this World Series, the Toronto Blue Jays have to pretend that it doesn’t exist.

One evening, the Rogers Centre crowd is roaring, nine runs are crossing the plate in a single inning, the bass in the home clubhouse is rumbling through the lower level of this venerable facility and a fog machine and blue lights frame the giddy afterglow of a World Series Game 1 win.

And 24 hours later, quiet enough to hear the visiting team’s shouts when a ball clears the fence, suitcase zippers engage as bags are packed in the clubhouse and a plane readied for a cross-contintental trip that may end with their season concluding in disappointment.

The Blue Jays are professionals, however.

They are paid very well to compartmentalize - or purport - that Toronto 11, Los Angeles 4 on one night and Los Angeles 5, Toronto 1 the next doesn’t hit any different than a win followed by a loss on an August weekend in Kansas City, say.
