STARTER/BULLPEN CORRELATION SYSTEMS
Better bullpen small favorite teams in the -111 to -126 range are thriving in 2026
In the 2026 regular season, small favorite teams in the -111 to -126 line range with a SM Bullpen Rating edge fared quite well. Last season this was about a -6% ROI angle. However, there is some foundation to the system in that with teams this closely matched together by the oddsmakers, it can often be good bullpen performance that separates the teams. For 2026, these teams finished 266-187 for +45.33 units, an ROI of +10% (4-0, +4.00 units in the playoffs).
