A few months ago, I put together an OL team just for fun, with two goals in mind:  steal a lot of bases (not playing a lot of OLs I didn't know high steals was a current gambit), and walk as few batters as possible.  I stole a lot, but was really impressed with the walks: with about a half-dozen games to go, I had a chance to make the Top Three All-Time.  The record is 102 walks in a season; third, 120.  My team made the playoffs, and I gave up my shot at the record list to rest my starters - I wound up with about 126 walks, as I remember.

That encouraged me to go all-out to get on the list of top three fewest walks.  I had an inauspicious beginning, walking three the first game; I quickly rebounded, walking none the next six games, then walked six the next four.  I settled down after that; the season just ended, and I wound up not only making the Top Three but actually setting the record - walking only 98 players the entire season.

Some numbers:
0 Walk Games: 89 (55%)
1 Walk Games: 53 (33%)
2 Walk Games: 15 (9%)
3 Walk Games: 5 (3%)
4+ Walk Games: 0
BB/9: 0.606

Nice... since this version of the SIM has been in place for so long, breaking any of the records is a pretty good feat.  How'd the team do overall?

Not terrible - 76-86.  I gave no consideration to offense when drafting my position players, and wound up with three Gold Gloves - and, surprisingly, one Silver Slugger.  I was also impressed with '13 Christy Mathewson, who (in a four-man rotation) won 24 games and was third in Cy Young.

That's cool.   who were some of the pitchers besides the 13 Mathewson? 

My rotation was '13 and '14 Mathewson; '94 Saberhagen (my only pitcher with a BB/9 over 1.00 for the season - in fact, my only one over .65), and '10 Cliff Lee/'63 Hal Brown in Tandem.  My pen was '89 and '90 Eck ('90 Eck walked one batter in 83 innings); '40 Podjany; and '70 Navarro (who walked none, albeit in only 24 innings). 

I knew I couldn't rely on AAA pitching (never called them up), so I drafted 1350 innings and crossed my fingers I wouldn't get into too many extra-inning games early: I would up with 18 extra-inning affairs (third in the league) and 1455 IP for the season.  I had to shuffle things around a couple times, but generally avoided any serious fatigue issues: 58 complete games (not including Tandem games) helped a lot.

Pretty cool.  I set the stolen bases mark for a season a little while ago after about 3 tries.  One of my teams got in the top 3, but the record never posted because my team winning percentage was under a certain number.   Which made me ask the question:  How does the sim recognize some of the "bad" records like most losses in a season, etc (162)?   Are those teams not held to the same winning percentage qualifiers?

Precisely.  Also, you can be 'disqualified' for other reasons.  For example, there used to be a theme (haven't seen it in a long time) where you predicted the number of wins you'd get (the commish set out the numbers from which you could choose, so there was a wide disparity).  One time I selected 123 wins and hit it exactly.  However, since other teams were intentionally trying to lose (having selected, say, 40 wins) my record didn't count - rightly so, I might add.
