Entering 2012, ESPN's Keith Law raved about Montero's advanced approach at the plate and compared him to Frank Thomas, but the prospect didn't exactly deliver his first year with the Mariners. His strikeout rate dropped dramatically to 17.9 percent, but so did his walk rate (5.2 percent), wOBA (.295), ISO (.126), and wRC+ (90). From here we know the rest of the story. Montero struck out more, walked less, and never hit for power or average at the major league level.
