Very interesting about the starting pitchers getting to take off away games when they won't be pitching. Saw some pitching restrictions and it would seem that a solid starting pitcher would normally need 3-4 days rest (51 pitches gets you 3 days rest). If you really skinny down the pitching (say <80 pitches - 3 days rest) and go maximum on the restrictions, then I would assume no more than 2 starts each week with 3 starts every two weeks probably being more realistic.
Not sure if travel was a big issue at Martha's Vineyard, but is it normal in summer ball for the previous night's starter to not necessarily travel with the team and basically get the night off?
