1. By the Numbers
Altuve, lifetime, has managed a .307 batting average, an .824 OPS and a 174 OPS+. On Baseball Reference, Altuve passes two of the four Hall of Fame Tests. He is above the threshold on the Black Ink and Hall of Fame Monitor tests, but he just barely fails the Gray Ink and Hall of Fame Standards test.

The player that Altuve lines up best with through age 31 is Ryne Sandberg, who is in fact, in the National Baseball Hall of Fame.
Verdict: Numbers alone, I believe that Altuve is a Hall of Famer.
