Player records show some pretty irrelevant stats, but there are some glaring omissions. 

I'd like to see:

Pitchers:
No Hitters
Holds

Batters:
Multi-HR Games
Walk off HRs
Left on base

There are probably lots more, but these are off the top of my head.

Showing no hitters thrown is the big one for me. How is this not tracked somewhere? (or am I missing it?)
