Yes and no. Was just talking about this with my son, who is a baseball player. He is desperate to go out to a park and throw long toss, which is a primary developer of arm strength, with one of his teammates. Even though the closest they would get to each other is 15 feet (and at max they would be over 250 feet apart), there's the thing of the ball traveling between them and any virus that could travel on that between hands. Obviously, caution is the name of the game right now and I'm not sure we have the confidence yet to understand transmission really well. Are catchers more at risk because they are within a foot or two of every batter on the opposing team? Is "going to the mouth" forbidden in any way? I'm sure it can all be worked out, but I'm not sure it will be worked out all that more quickly than the NBA and NFL.
