grimshaw said:I don't think you're missing anything and not sure how B-Ref differs. Fangraphs has him at 3.2 BsR (baserunning runs above average) which incorporates (quoting directly from Fangraphs):
"1) On a hit, advancing an extra base, not advancing an extra base, or getting thrown out trying to advance an extra base, as long as no other base runner is blocking an advance.
2) A batter getting thrown out trying to advance an extra base on a hit (if he successfully does, we don’t know it, as he is simply awarded a double, for example, on a usual single where he advances an extra base).
3) On a hit, the batter advancing, not advancing, or getting thrown out when a runner is safe or out advancing an extra base.
4) Trailing runners advancing, not advancing or getting thrown out when a leading runner is safe or out trying to advance an extra base on a hit or an out. This is basically lumped together with #1 above.
5) Runners trying to advance on fly ball outs – i.e. tagging up.
6) As mentioned above, on ground balls to the infield, runners on first staying out of the force or DP at second base, whether the batter is out or is safe on a FC.
7) Also as mentioned above, a runner on second advancing or not (or getting thrown out) on a ground ball hit to SS or 3B.
Runners on third base advancing, not advancing, or getting thrown out at home on a ground ball are not considered (on air balls they are). Runner advances or outs on WP or PB are not considered either.*
8) Getting hit by a batted ball ??
