It's the HR's that are skewing his SLG. He's hit one every 42 at bats, compared to once every 410 in the minors. take a look at torii hunter's minor leauge stats. how does a guy with 42 career minor leauge hr's in 6 years and a career sluggin % under .400 hit 25-30 each year in the majors? according to your logic it shouldnt be happening but it is. Torii Hunter hit 60 homers in seven minor league seasons. Regardless, there are flaws with your argument. First, you didn't look at the number of at-bats, instead just focusing on the number of seasons. Second, he did hit a decent number of doubles, which for some players can translate into home run power as they mature. Third, he reached the majors at age 22. Theriot is much older than that. Hunter's first season in the minors, he hit no homers in 100 at-bats at the age of 18. Probably didn't have much experience with wood bats prior to that. The next year, he hit 10 homers in 335 at-bats, slugging .439. Power can develop as a hitter matures. It's much easier for someone that age to develop more power than it is for a 27-year old with absolutely no history of power at all. Fourth, Hunter's career OPS in the minors was roughly .750, which isn't too far off his major league OPS of .786.
