After playing around with David Pinto's Day by Day Database a bit, here's a look at the 2000's leaders (the aughts?) in a few categories. Of course, guys who came up early in the decade or were active even before 2000, have an edge here.
Hits-Ichiro (2030); Jeter (1940); Tejada (1860); Helton (1756); Vlad (1751).
HR-A Rod (435); Thome (368); Pujols (366); Manny (348); Delgado (324).
BA (min. 2000 PA)-Pujols (.334); Ichiro (.333); Helton (.331); Mauer (.327); Vlad (.323).
And for pitchers:
Wins-Pettite (148); Unit (143); Moyer (140); Hallday (139); Oswalt (137).
Innings-L. Hernandez-(2201 1/3); Vasquez ( 2163); Buerhle (2061); Zito (1999); Moyer (1980 1/3).
I had no idea Javier Vasquez would be on this list, though I'd known he was an innings eater. He might be a real coup for the Yankees as their fifth starter, as most teams really struggle to find adequate guys at 4 and 5-and some with 1,2, and three.
There's not much talk about Carlos Delgado's HOF chances, but you have to say his overall numbers impress (473 HR, 138 OPS+). He'd have to have a shot, you'd think, though he's certainly been under the radar. His problem will be that he's almost never led the league in anything-doubles once, RBI once, TB once, OPS+ once-and, possibly for this reason, has only two All Star selections. I'd vote for him, myself.
