The American League Batting Averages
During the Rays/M’s game, announcer Dewayne Staats noted that Carl Crawford’s .307 batting average was good for seventh best in the American League. Erik Hahmann – my co-writer at DRaysBay – questioned the rank, insinuating it seemed a little on the low-end for a top 10 BA. Sure enough, Staats and the Rays media notes were correct.
22 AL batters (who have qualified) have recorded hits in roughly 30% of their total at-bats; last year 17 hit .300; 20 in 2007; and 20 once more in 2006. How about Erik’s assertion that .307 usually doesn’t land you in the top 10? Here are the cutoff averages – so to speak – of the tenth highest BA in each of those years:
2008 – Nick Markakis .306
2007 – Dustin Pedroia .317
2006 – Reed Johnson: .319
In some ways this is a renaissance of .300 hitters on the Junior Circuit – the Angels are to thank for some of this – however the quality of the best batting averages appears to be slipping a bit. The first reason that pops to mind for deflated batting averages is an increased emphasis across baseball on defense. The A.L. features the Rays, Mariners, and Rangers – three of the best defensive clubs in the game – and if this is the case, shouldn’t it show up in the league’s non-pitcher BABIP rates? Let’s look.
2009 – .305
2008 – .303
2007 – .309
2006 – .307
Nothing there other than simple fluctuation. The only other thing I can think of is a possible increase in strikeouts. Here are those totals:
2009 – 20.4%
2008 – 19.6%
2007 – 19.6%
2006 – 18.5%
Well, there’s certainly something there, albeit not nearly enough to point to an increase in whiffs as the reason for deflated batting averages. Does it play some kind of role in the change? Certainly.
It’ll be interesting to see if the league strikeout rate continues to climb into next season and whether batting averages continue to drop.

I would think there might be a bigger effect to better defenses than just that they are better at preventing hits. As a group, better defensive players also tend to be worse hitters. That effect would probably show up in K%, BABIP, and HR%, which would all adversely affect batting average.
I don’t think you can just look at the top 10 hitters or at .300 hitters and get a grasp on what is happening league-wide, though. If you notice something strange about the top 10 or .300 hitters but don’t look at the league-wide numbers to see if the change is reflected in the league totals, then looking at the league-wide components for changes isn’t necessarily going to tell you anything about what you are seeing.
Maybe the group of players that skewed high or low were just disproportionately focused on the group of hitters at or away from the top hitters for average in some of those years. If the true talent of the league stayed the same, and you know that a certain percentage of the league’s hitters are going to hit so many points away from their true talent, then where the hitters who skew high or low fall on the true talent spectrum could result in the kind of discrepancies seen here without any systematic shifts in hitting in the AL.
I like your logic, but I think that almost player who can hit .300 would still find a starting job in the Majors

If someone told me that fangraphs was going to post an article about AL batting averages AND Joe Mauer wouldn’t be mentioned, I would have told them that they are probably incorrect. But I would have been the one who would have been incorrect!
Or Ichiro. Cats and dogs living together, etc….
AL pitchers are better than NL pitchers. The worst pitchers in baseball – and by that I mean, the bottom 5%, talent-wise -almost all pitch in the NL now, because both players and teams are getting more realistic about the difficulty of pitching in the AL and appropriating players where they can be successful.

Averages can be deceiving. ALL Red Sox should have an astgerisk beside their info to note that they jacked up their stats by playing half the season in Fenway — “never enough runs in Fenway” , “Can’t foul out in Fenway”, “when you need a hit, maybe even a double, lift a lazy fly to left in Fenway, anfd right field fence is three feet high in Fenway.
The great Ted Williams would never have accumulated his lofty stats had he played in almost any other park for half of his games each year.
