Fielders get a team decorated golf style umbrella to hold over their heads during the many games played in heavy rain.
The pitcher gets to stand under a canopy. The batter gets to stand under his own canopy.
Hey, it makes sense. Especially with all that rain poring down.
I still prefer my previous suggestions but MLB does not seem inclined to adopt them soon so I thought that these simple practical ideas would improve things in the short run.
