Poor weather conditions in the Bronx forced the postponement of Wednesday's game between the Yanks and Blue Jays. It was to be the first of short two-game series. The two American League East teams will try again tonight with a scheduled 7:05 p.m. start time, but that game may be in jeopardy, too. A 70 percent chance of rain is being forecasted for tonight. No make-up date has been announced for Wednesday's rain out. The last-place Yankees welcome the Red Sox to town for a three-game series beginning Friday, when a 60 percent chance of rain and thunderstorms are being forecasted.
