Guys Near the Top Both Before and After 30

I've been on this up through and after 30 kick lately; I was wondering: how many players have been so dominant in a major statistical category that they appear in, say, the top three all-time on both the up through 30 and after 30 lists. As you'd expect, it's pretty rare. Here's what I found as far as hitters go:

Batting Average: Ty Cobb ranks 2nd all-time through age 30 (.370) and 1st overall after 30 (.362).

On Base Percentage: Ted Williams is 1st thru 30 (.488) and 2nd after 30 (.474).
Babe Ruth is 2nd thru 30 (.475) and 3rd after 30 (.473)

Slugging Pct.: Ruth is first both thru 30 (.697) and after 30 (.684): that's why he's the Babe!
Ted Williams is 2nd before 30 (.642) and 3rd after 30 (.624)

Total Bases: Hank Aaron is 3rd both through 30 (3692) and after 30 (3164)

Triples: Sam Crawford is 1st thru 30 (193) and 3rd after 30 (116)

Stolen Bases: Rickey Henderson is 1st thru 30 (871) and 2nd after 30 (535).

At Bats per Home Run: Ruth is 1st through 30 (12.7) and 2nd after 30 (11.0).
