OPS
On-Base Plus Slugging -- a combined hitting metric adding on-base percentage and slugging percentage to measure overall offensive production.
Like combining a student's GPA and test scores -- a quick summary, but not perfectly weighted.
Why it matters
OPS gives a quick read on a hitter's total offensive value. League average is around .720; elite is .900+.
How DMP uses this
DMP references OPS when evaluating hitter quality for total bases and run-scoring prop projections.
Common mistake
Treating OBP and SLG as equally important -- OBP is actually more valuable for run creation, but OPS weights them the same.
