So, here's some tentative predictions as to where he'll finish on some counting, and sabermetric, numbers in relation to Babe Ruth, Ted Williams, Stan Musial, Hank Aaron, Willie Mays, Mickey Mantle, Barry Bonds, Alex Rodriguez and others, whether great classic figures of the past or people with some "help" in more recent years.
That includes noting that he has an outside shot at becoming the all-time leader on at least one counting stat.
First, slugging percentage. Pujols is currently seventh. I expect him to fall no lower than No. 11, staying ahead of current No. 12, Miguel Cabrera, and possibly just to ninth, ahead of current No. 10 Joe DiMaggio. That would still leave him above the majority of people on the list above.
Park-adjusted OPS+ is a good all-around measure of a player. Pujols is currently 10th, at 165. Aaron and DiMaggio are among a group tied for 22nd at 155. Cabrera and Joey Votto are among those tied for 25th, one point lower. Ed Dehalanty is 30th at 152. I certainly don't see Pujols going lower than that.
Next? Total bases, where Pujols is No. 50, with just over 4,450. A strong, but not overly aggressive prediction of 1,950 for the rest of his career gives him 6,400, behind only Aaron. Even a conservative estimate of 1,680, or 225 per year, which he's easily done every non-injury year, still puts him ahead of Musial in the No. 2 slot. (And yes, Stan Musial is No. 2 in career total bases; I just wish more semi-casual, but semi-serious, baseball fans would see this and recognize just how damned good he was.)
In RBIs, Pujols is 49th. He's 773 behind Aaron, 690 behind Ruth and
And, finally, Pujols has a semi-reasonable shot at becoming the career leader on one list. That's if he can get about 430 more total extra base hits.
As of early May, he was 25th on the career list, 428 behind Aaron and 391 behind Bonds. If he has 58 extra base hits the rest of this year, for 76 on the season, that leaves 360 in the next seven years. Just 52 extra-base hits a year puts him past Aaron.
Possible? Yes, but not easy. For obvious reasons, I'm not going to look at Bonds.
A few others:
Aaron had 318 extra base hits his last seven years
Ruth (not counting his partial year in 1935): 495.
However, especially with not counting 1935, Ruth's career ended three years earlier than those other gents. For his last four full seasons, he had 240 extra-base hits. But, 47 a year over three more extrapolated years would put him at the 380 mark.
So, it's possible. And, just 46 extra-base hits per year after this year puts him after Bonds.
