Vladimir Guerrero Jr. Accelerates to the Finish
Guillermo Martínez is 34 years old, last played pro ball eight years ago for the independent Grand Prairie (now Texas) AirHogs, and never made it above High-A in affiliated ball. He is also the rookie major league hitting coach for the Toronto Blue Jays. There’s a long history of men who never achieved much in their playing careers becoming outstanding in second acts as coaches, and in his responsibility for the offensive success of Toronto’s much-vaunted youth movement (the average age of their hitters, 26.2, is the youngest in the American League), Martínez has more than enough raw material to make his mark in his first season in the role.
Last week when the Blue Jays came to Seattle to take on the Mariners (dropping two out of three), I sat down with Martínez to talk about his first year of coaching in the majors, and in particular his first year of coaching another, much more famous, rookie: Vladimir Guerrero Jr.
After making his debut for Toronto late in April at the precocious age of 20, Guerrero has had an up-and-down — or, more accurately, a down-and-then-up — season for a middling Toronto club that is nonetheless understandably optimistic about the cohort of young hitters of which Guerrero is a part. First, the down: Through the end of June, across 226 big-league plate appearances, Guerrero had posted a wOBA of just .317, and — even more worryingly — was striking out far more (19% of the time) and walking less often (9% of the time) than at any previous level.
Some regression was to be expected, of course, upon facing big-league pitching for the first time. But it wasn’t just that the results that were underwhelming. It was that they matched up with the story told by the eyes. Read the rest of this entry »
