Since when?

I have Hughie Jennings on one of my teams. So far, he has 89 AB, 25 H, 1 BB, and has been hit by 11 pitches. But the team stats file says he has an on-base percentage of .304, which is consistent with, well, nothing. 26 times on base in 90 PA's is an OBP of .289. His .304 OBP is consistent with 25 H, 1 BB, and 2 HBP, where did they find that 2?

Any chance he has about 20 sac bunts and/or flies?

sac bunts wouldn't do it as they don't count as a plate appearance. it seems like he would have to have 20 sac flies, which seems a bit high for that early in the season.

This calculation sure seems off.

sac bunts and sac flies count as a plate appearance , not a time at bat , but is reflected in on base percentage

you are correct, I misspoke. It is a plate appearance, but does not count against OBP. Sac flies do count against OBP.

I had John Mcgraw before and HBP for some reason was not included in his OBP. I think that must be happening here as well although more recently I thought for Hughie they were including HBP into OBP.
