Interleague Stats

This was buried in one of the other threads:

Here are the yearly records since it started.

YEAR	AL	NL	Win Pct
1997	97	117	.547
1998	114	110	.509
1999	116	135	.538
2000	136	115	.542
2001	132	120	.524
2002	123	129	.512
2003	115	137	.544
2004	126	125	.502
2005	136	116	.540
TOTAL	1,095	1,104	.502

Last I checked, the AL is on their was to approx a .620 Win Pct this season - which is huge compared to what's gone on before. It's like a 100-win team is playing against a 60-some win squad.
This doesn't show home/road stats but I'd be surprised if they're anything out of the ordinary ~ 55/45 split that most MLB games show.

These things are usually pretty cyclical but there seems to have been a lot of NL --> AL migration in the last few years.

Interesting. Didn't think it was so even--though after this year it won't be. Going to see if I can track down interleague home/road splits for this. Just to satisfy my own curiosity.

NL Record

1999 135-116
2000 115-136
It can turn around that quickly.

I hate the American League. DHs are stupid, and the f-ing games take forever.

The game intro on YES today showed this year's home/road IL breakdown. I didn't write it down or anything but the AL was winning in their own parks at about a 3-of-4 clip while the NL was just short of breaking even in their home games.
And that's about what you should expect. The usual 55/45 home/road record assumes that the teams (or in this case, leagues) are playing more or less even. But a team playing around .620 ball against a .380 or so opponent (what the AL/NL are doing now) would win around 70-some pct of their games at home and just over 50% on the road.

..............verrrrrry interesting.

NL getting killed again tonight.

It would have been worse except that the Reds came back from being down to Cleveland 7-1 in the 8th - including a 2-out, 9th inning, down-by-three, walk-off GS from Adam Dunn

5th time in the last 20 years where there was a walk-off GS by a team down by 3 runs w/2 outs in the 9th.

NL actually won the day on the final day of IL play (no thanks to us of course) but the final totals for this year give the AL about a whopping 61/39% edge. No other year prior to this had one league winning as much as 55%

To put that into perspective; the AL won at about the same rate as the ChiSox did last season, while only the Royals in 2005 played worse than the NL did during this year's IL sked.

From 'Hardball Times'

... from 1998 to 2005, the NL has had a 54.7% winning percentage at home; the AL's is 54.2%,
compared to a 53.6% win percentage at home for all teams, including interleague games

In other words, the theory that home teams in Interleague games would have an "unfair" advantage based on playing with their own rules in their own park doesn't really hold up.
Home teams in IL games have only a slightly better winning pct than home teams do in all games.
