Assuming a fairly standard .300 BABIP, CBYoung should be hitting .273 right now. He has struck out 22% of his at-bats, for a solid if unexceptional 78% contact rate. 80% contact rate hitters can generally get an average b/w .280 and .300 if they hit for solid power, meaning 25-35 homers a year.
He has been very unlucky this year. Compare him to Curtis Granderson, a player I also own and love. Granderson K's about 24% of the time and has an unexceptional walk rate (although slightly better than CBYoung's). He also has only hit 16 homers, so 9 less than CBYoung. Yet his average is .288.
If Young had average luck, he would be on pace for a .275/30/60/100/30 season now. Next year, he's definitely worth a high pick, at least as high as Granderson and Eric Byrnes and some other outfielders who've surprised this year.
