Minor Numbers Vargas .288 avg, .367 OBP, .486 slugging, .854 OPS. 24.2% K percentage Walker .259 avg, .312 OBP, .484 slugging, .796 OPS, 27.8% K percentage At the time of the promotion, Vargas had an OPS of .832 with 17 HR in just 97 games at AA. He was putting up better numbers at AA than Walker has in the lower leagues without the red flags. It seems to me you put Walker in the big leagues next year and he hits about .225, his OBP is about .260, and he wiffs about 35% of the time.
