April Showers

The new baseball season started this week, and already some games have been postponed or cancelled. Why is this? Because baseball isn't played in the rain. But for some reason, the powers that be felt it would be good to start the season in April, which is known for its rain, as immortalized by the rhyme, "April showers bring May flowers." Why would they pick the rainiest month to start a sport that you don't play in the rain? It would be like if November, the starting month for hockey, had a rhyme, "November is very nice for melting indoor ice."
