Most PA, SLG under .300

A comment on Brew Crew Ball talking about Joey Gathright made me think of this. The Royals speedster put up a .292 slugging percentage in 445 plate appearances for Tampa Bay and Kansas City in 2006 and I thought it'd be interesting to see who has the record for most plate appearances in a season slugging under .300.

The record is higher than I figured, with nine seasons topping 700 PA:

1. Sandy Alomar, 1970, .293 SLG, 735 PA
2. Donie Bush, 1914, .295, 721
3. Roger Metzger, 1972, .259, 715
4. Ozzie Smith, 1980, .276, 712
5. Tom Brown, 1892, .285, 712
6. Don Kessinger, 1968, .287, 707
7. Woody Williams, 1944, .289, 707
8. Ossie Vitt, 1916, .295, 705
9. Donie Bush, 1915, .283, 703

1,377 players qualified for their league's batting title while slugging under .300. I doubt any won it. Here's another list, this time of the top ten career PA leaders slugging under .300:

1. Mark Belanger, 1965-1982, 6602 PA, .280 SLG
2. George McBride, 1901-1920, 6235, .264
3. Bud Harrelson, 1965-1980, 5516, .288
4. Sandy Alomar, 1964-1978, 5160, .288
5. Cub Stricker, 1882-1893, 5083, .294
6. Al Bridwell, 1905-1915, 4928, .295
7. Roger Metzger, 1970-1980, 4676, .293
8. Rabbit Warstler, 1930-1940, 4611, .287
9. Ossie Vitt, 1912-1921, 4486, .295
10. Tommy Thevenow, 1924-1938, 4484, .294

The active career leader is Greg Maddux with 1750 (slugging .208). The position player leader is 37-year-old catcher Alberto Castillo with a career slugging percentage of .297 in 1173 PA.
