Buying Low on Miguel Cabrera by Eno Sarris July 25, 2017 At 34, in the middle of his worst season so far and with $200 million left on his contract, Miguel Cabrera hasn’t inspired many trade rumors this year — and perhaps rightfully so. But that doesn’t mean he hasn’t inspired any. His general manager said he would listen on veterans, and Alex Rodriguez floated the idea that Cabrera would make sense in Boston. Is there a chance Cabrera could be moved by the end of August? To determine if such a deal would be desirable for both the Tigers and a prospective trading partner requires multiple considerations, from Statcast to the weather, from aging curves to the cost of a win. The most compelling argument for acquiring Cabrera is that he’s still a premier slugger in the game. Or, at least, there’s some evidence that he should still be a premier slugger in the game, if the batted-ball data is any indication. Statcast identifies Cabrera as possessing the second-biggest differential between his real and expected outcomes. He’s hitting the ball hard and in good angles! Buy! Scan down the list, and you may immediately notice three other Tigers prominently placed. Tyler Collins and Alex Avila join Cabrera in the top 25, and James McCann, Nick Castellanos, Andrew Romine and J.D. Martinez have also been unlucky by their metric. Seems like there might be something brewing in Michigan. Let’s take a look at those Tigers and how they’ve faired at home and away. In particular, we find that Cabrera has enjoyed recorded exit velocities that are nearly four ticks faster at home.

But there’s also a general trend here. If you weight the exit velos for all the Tigers by home and away plate appearances, you get a .77 mph difference between the club’s exit velos on the road and at home. So, that’s interesting. It seems possible that Statcast has introduced a secondary park factor just by existing. We knew temperature and altitude were big deals when it came to how far the ball would travel, but now it looks like the machines themselves, and their various calibrations, are adding a layer of difference between parks. How normal is it for such a differential to exist? To determine that very thing, I examined the average exit velocities in all 30 major-league stadiums. Doing so reveals that Comerica Park has produced the second-highest batted-ball speeds. Balls do travel faster in hot weather, of course, so you can add a weather adjustment, as Andrew Perpetua has done in his expected stats numbers. Detroit (and Cincinnati) still have something weird going on.

He should be hitting .295/.379/.503 instead of the .256/.346/.422 he’d recorded entering play yesterday. Here’s one thing for which it’s impossible to adjust, just yet anyway: outfield walls. The sample gets too small when you bin balls by exit velocity and launch angle and then limit it to the park. So, let’s look at Cabrera’s batted balls this year overlaid on a map of his park. Look at that right-field cut out. It’s probably costing Cabrera a homer or three. And it might be a problem for pull-power lefties, too. Take a look at that area of the park, and it immediately stands out when you’re scanning the outfield. (Photo: MJCdetroit) If you were a general manager contemplating an acquisition of Cabrera, you may want to compare Comerica to your own park factors. Take Citi Field just as an example, in the image created by Perpetua below. Yeah, right field at Comerica is tough on righties with oppo power or pull-power lefties. Before we draw any conclusions, however, we should look really quickly at Cabrera’s spray chart last year. Wait up. That’s different. Here we find a healthy collection of homers all along the left-field wall. This year? Not so much. And the numbers support what these charts suggest. Consider: only 10 qualified batters saw their pull percentage go down more from last year (37.8%) to this year (32.6%). He’s not poking them out to left-center any more. Where did Cabrera’s pull power go? Well, some of is it just where he’s being pitched. Look at the heat maps below, for example. On the left is 2016; on the right, 2017. Cabrera was getting jammed in on his hands more last year with fastballs. So that’s an explanation. But if Cabrera can’t pull those pitches down the middle that you see in the heat map on the right, isn’t there a problem? We know that barrels to certain parts of the park don’t do as well as barrels to other parts, that horizontal spray is important, and that the power alleys are generally where you want to aim. Cabrera used to be brilliant at hitting both power alleys, and now he’s only going oppo. His pull power has been zapped by something. If you return to his “expected” line, you’ll notice that Cabrera’s expected .882 OPS is actually below his Steamer projected rest-of-season OPS (.939). Given the ups and downs we’ve uncovered while looking at that expected line, and the fact that he’s been battling a groin injury and now has added a collarbone issue, it might be a bit much to expect anything more than his Steamer output, which would make him a league-average first baseman. Given the most recent price-per-win numbers, you might want to pay something like $20-25 million dollars a season for that production. Cabera is due $30 million a year for the next six seasons, and we haven’t even begun to add aging effects. And that’s the math that means that we probably won’t see Miguel Cabrera in a new uniform on August first. Even if the Tigers swallowed half of what was left, it’s hard to see teams considering that package of price and production worth trading for. If you’re just a fan rooting to see the Cabrera of old, watch the health updates. A working collarbone and pain-free groin could be all he needs to recover some of his pull power.
