Trent Grisham Did the Thing He Can’t Do

They say that the first step to fixing a problem is admitting that you have one. In that spirit, I’d like to start today’s article with a confession: I have a Trent Grisham evaluation problem. It feels good to say it! I’ve had this problem for years. Ever since he burst onto the scene in San Diego with two straight seasons of good hitting and great fielding, I’ve consistently overestimated his future trajectory. I put him on the first cut of my trade value list every year. I think of him as a starter even when the teams that employ him don’t.
I know all of this. When I’ve looked at Grisham in the past, I’ve seen an excellent player even when others haven’t, and I understand that this bias shades my evaluation. But just when I thought I was kicking the habit, Grisham goes and does something like this and pulls me right back in. Through Monday’s action, the first quarter of the season, he’s hitting a ludicrous .288/.373/.663, and while that’s not any reasonable hitter’s slugging percentage, he’s absolutely tattooing the ball, posting career high marks in barrel rate, hard-hit rate, xwOBACON, xSLG, average exit velocity… You get the idea, he’s just hitting everything very hard at the moment.
Now, as a reformed Grishamite, I have to tell you that hitting the ball hard isn’t one of Grisham’s shortcomings. Not quite like this, of course, because the only person who regularly hits like this is Aaron Judge, but he’s always been a threat to go deep. Grisham might have a low-ish wRC+ over the past three years, but the problem has been the quantity of his hits rather than the quality. Even while he scuffled mightily, he slugged roughly 20 homers per 600 plate appearances. He doesn’t always put the ball in play, but when he does, he makes it count.
Grisham also forces pitchers to come to him. He’s among the league’s best when it comes to chase rate, and he’s walking at a double digit clip. Again, though, I have to tell you that this isn’t new. Grisham’s chase rate is higher than it was last year, and his walk rate is below his career average. Unlike your typical outfielder with a below-average batting line, this isn’t an issue of Grisham never seeing a slider he doesn’t like. He’s quite willing to work a count if pitchers won’t challenge him in the zone. Read the rest of this entry »
