Mike Yastrzemski, Patient Thumper
There weren’t a lot of bright spots on the 2019 San Francisco Giants. Pablo Sandoval was fun here and there, particularly when he pitched. Alex Dickerson hit a few dingers. Donovan Solano isn’t cooked just yet. For the most part, though, those were marginal. The real splash, the only real splash, was Mike Yastrzemski, who went from feel-good legacy to bona fide major league outfielder in the course of one slugging season.
2019 was already surprising enough for the career minor leaguer. After showing flashes of patience, power, and a feel to hit in previous seasons, he put them all together in Triple-A Sacramento, and there was no one blocking him from the majors. Four hundred plate appearances and a .272/.334/.518 batting line later, he was the best outfielder on the team, and the Giants were constructing their 2020 roster with one spot on the depth chart written in pen.
If the start of 2020 is any indication, however, last year wasn’t Yastrzemski’s ceiling. His ceiling is this year’s white-hot start: .310/.473/.643 with three homers, good for a 204 wRC+. Oh yeah — he’s playing freaking center field every day, too. Twelve games does not a season make, but if you could make his whole season out of the last two weeks, he’d basically be Mike Trout — an up-the-middle defender with a 200-ish wRC+.
Is he a good fielder? It’s unclear. He looked good both by the eye test and by the advanced statistics troika of DRS, UZR, and OAA last year in the corners, and looks at least reasonable in center so far this season. He’s not a long-term premium defender — he’s nearly 30, for one thing, and has only average straight-line speed — but tuck him in a corner, and he’ll be inoffensive at worst and an asset at best.
But the exciting part about Yastrzemski isn’t the fielding, at least not mostly. It’s the offensive value, the leading-baseball-in-WAR offensive explosion that makes Giants fans mostly shrug their shoulders but also rub their hands together greedily when they think no one’s looking. Sure, it’s early. Sure, it’s not our year. But it could be real, right? The team could have found a new superstar, right? Read the rest of this entry »
