In that almost 13,000 game sample size since 2017, here are a few notes on unders: 500 for six consecutive seasons dating back to 2017 (basically a 51% unders, 49% overs situation).
Even though its been a small margin, unders have been above. Unders have been the rage in MLB for some time now.Of those six seasons since 2017, only one produced a profitable season for big favorites on the run line. A simple question: How do big favorites perform on the run line? We started seeing big favorites really in 2017 - since that year, we've seen 286 teams close as a -300 favorite or higher.
