"Vladimir Guerrero Jr. will need to have a pretty remarkable career in order to match the exploits of his father. Vladimir Guerrero Sr. hit 449 home runs and logged a 931 OPS in 16 big-league seasons. He did so with one of the most-aggressive approaches of his generation.
According to Blue Jays farm director Gil Kim, the top prospect in the Toronto system isn’t a chip off the old block in every respect. When I asked him what stands out about the 18-year-old third baseman, he gave an answer I wasn’t expecting.
“Strike-zone discipline,” stated Kim. “You look at Vladdy’s tools, and it may be easy to overlook the fact that he has more walks than strikeouts right now. That’s pretty impressive. Most people look at the power, and the sheer tools, but he controls the zone pretty well. Strike-zone discipline and instincts are two areas that have us really excited about Vladdy.”
In other words, the son didn’t inherit the swing-at-anything-close from his father.
“He did not,” agreed Kim. “But his hand-eye coordination is good enough to where if he did, he’d probably still be successful.”
Guerrero is slashing .328/.430/.512 in 35 games with the low-A Lansing Lugnuts. At the time I talked to Kim, he had drawn 20 walks and gone down on strikes 18 times in 143 plate appearances. He has four home runs."
