Former major league infielder Trevor Plouffe tweeted about an hour ago:
I just heard from multiple sources that on June 10th, Spring Training 2 will start. July 1st will be Opening Day and all teams will be playing at their home ballparks.
Interestingly, that echoes what a SoSH post from last Friday stated:
My friend who often gets second hand early MLB scoops says "Season starts 7/1, tons of double headers, only arguments remaining are around service, 100+ games played and so forth, destinations still unknown.
I am extremely skeptical. This would mean every state with a major league team would agree to resume some level of public activity in five weeks.
