No doubt there have been MLB power hitters who can successfully hit the other way, like Ortiz -- but that's not the question. Can a power hitter who *almost exclusively* hits the other way have sustained MLB success? As to the Ortiz example, more than half of Ortiz's career HR have been pulled, according to B-Ref. He's a good hitter who is also good at going the other way. Colabello hasn't pulled anything at MLB level yet (B-Ref says 4-22 with no XBH in his career, including a scant 0-for-2 this year so far -- closest he's come I guess is just left of center, which still counts as "up the middle"). Only 10.7% of his career AB have had pull outcomes (infield, outfield, outs,... everything pulled), and it's not trending up. Even Mauer has pulled 15.1% of his AB in his career, Ichiro is 17.3%... and these are left-handed AVG hitters. Can you imagine a RH power bat with a far lower pull rate than them? Again, love Cola, just setting out what I want to see before I can really believe: pull the ball! (Although if he can keep leading the league in RBIs in the meantime, I will enjoy that too. )
