Total Bases
The sum of bases from hits: single equals 1, double equals 2, triple equals 3, home run equals 4. Walks and other events do not count.
Like counting only goals in soccer, not assists -- valuable, but only part of the offensive picture.
Why it matters
Total bases is one of the most popular MLB player prop markets. It combines contact quality with power.
How DMP uses this
DMP projects total bases using ISO, barrel rate, and ballpark factors to identify mispriced lines.
Common mistake
Thinking total bases includes walks or HBP -- only hits count, so high-walk players underperform here.
