I did head to Sloan Park this morning. Not much activity there, maybe a couple dozen people milling around, and about 10:20 a.m. Arizona time it was announced the Cubs game vs. the Dodgers had been cancelled — due to rain.
It’s not raining at the moment in the Phoenix area, though storms are forecast for this afternoon. As of this writing, four other Cactus League games have been cancelled (Padres/Indians, Rockies/Brewers, Brewers/Diamondbacks and Reds/Mariners), and two others (Mariners/Royals and Athletics/Dodgers) are still scheduled.
