We have a -300 favorite sighting on tonight's MLB slate with Clayton Kershaw taking on Miami and Tom Koehler. Quick look shows 3-1 favorites or more have been on a roll of late -- as they should -- with 12 straight wins dating back to 2014. Kershaw was involved in eight of those 12 contests. And of those 12 victories, only one was by a single run. The average margin of victory was 3.9 runs. But going back to 2000, -300 or more favorites both on the moneyline and run-line has been a small loser. Totals during that span went under as a 57% clip.
