Detroit's outfield is 3 men down. Here's what that's actually worth, and it's less than it sounds

Riley Greene went on the 10-day injured list Wednesday with a right hamstring strain. He's got 492 plate appearances and an .816 OPS, easily Detroit's best outfielder, and he joins Matt Vierling and Kerry Carpenter, who are already there. 3 outfielders, on a team that's half a game out of the last wild card spot with 42 to play.

Worth being accurate about how big a bat this is, because I nearly wasn't. Greene is not Detroit's best hitter. Among the 6 guys with 300 or more plate appearances he's 3rd in OPS, behind Dillon Dingler at .844 and Kevin McGonigle at .819, and McGonigle has more plate appearances than he does. Greene's the best outfielder on the roster and the 3rd best hitter, and those are different sentences.

So it reads like the season just ended. I don't think it does, and I want to show you why, including the part that argues the other way.

First, they didn't all go down at once

This matters more than it sounds, because "we just lost 3 outfielders" and "we lost 1 more outfielder having already lost 2" are pretty different sentences.

From the league's own transactions feed:

Carpenter's been out 17 days and Vierling 14. Both of them passed their 10-day minimum a while back and neither is back, which is its own small worry, and plantar fasciitis is the kind of thing that lingers. But the point for right now is that Detroit's already been playing shorthanded for 2 weeks. Only 1 of these 3 is new information.

On Greene specifically, A.J. Hinch said the club thinks the strain is mild, and that Greene felt it slowing up at home plate and never hobbled, which Hinch called a good sign as opposed to a big mid-belly grab. A Cody Stavenhagen quote going around r/motorcitykitties has Hinch saying he wouldn't have been able to play the rest of this series or the White Sox weekend anyway, which I'm passing on second hand rather than from the piece itself. Take the 10-day minimum at face value and that's about 9 games.

Second, and this is the part nobody says out loud

Only 1 of the 3 was hitting.

Vierling's at .590. That's below the level of a randomly grabbed bench guy, and I'll show you where that .604 comes from in a second. Carpenter's at .692, which is under the league's .719 and under Detroit's own team mark of .727. Greene is the only one of the 3 who was clearly making the team better by being in the lineup.

The replacement number isn't something I remembered, it's derived. Every non-pitcher in baseball with under 150 plate appearances this season, 267 of them, 15,352 trips to the plate, hits .280/.324 for a .604 OPS. That's the population a club actually reaches for when a regular goes down, and it's exactly the group Detroit's reaching for now. Julks has 2 plate appearances this season, Clark has 50, Malgeri 57, Outman 100. All 4 of them are inside that bucket.

I deliberately did not use Detroit's replacements' own numbers as the baseline, because Max Clark hitting .804 in 50 plate appearances tells you nothing and using it would flatter the argument I'm making. The league-wide bucket is the more conservative choice and it's the one the math below runs on.

So what's it worth in wins

Fit runs per plate appearance on OPS across all 30 teams this season and you get runs/PA = -0.1218 + 0.3340 x OPS, r-squared .830. So 100 points of OPS is worth about .033 runs every time you come up. Detroit's scored 549 and allowed 462 in 120 games, which puts a win at about 10.4 runs.

Give each guy the plate appearances he was taking per game he played, times the games he misses:

Worst case, all 3 miss every remaining game, it's about a win and a half, and 79 percent of that is Greene. Vierling's line is negative, meaning the numbers say Detroit is very slightly better with him on the shelf, which I'd treat as "costs nothing" rather than as an actual gain.

The realistic case is the bottom row. Greene misses 9 or so, the other 2 come back somewhere in there, and the whole thing costs a quarter of a win.

Now the argument against all of that

Carpenter. His .692 is by a distance the worst season of his career. He went .811, .932 and .788 the 3 years before this one, 1,219 plate appearances that weight out to about .832. Treating a guy's worst 259 plate appearances as his true talent is exactly the error I'd complain about if somebody else did it.

Run him at .832 instead and he's worth 10.2 runs over 42 games rather than 4.0, right about a full win on his own. That takes the 3-man total from 1.52 wins to 2.12 and drops Greene's share from 79 percent to 57. So the honest version of the headline is that 2 of the 3 matter and 1 of them doesn't, not that this is all about Greene.

Small note on that .832, since I'd want to know: it's his 2023 to 2025 seasons weighted by plate appearances, which is an approximation. Doing it properly means rebuilding on-base and slugging from the raw components rather than averaging 3 OPS figures. It'd move the number a little, not enough to change anything here.

Vierling doesn't get the same defence. He was at .717 and .735 in his first 2 Detroit years, then .617 in 100 plate appearances last year, then .590. That's 2 years of going the wrong way, not 1 bad stretch.

A few other things this method can't see, and I'd rather say them than have you find them:

• OPS knows nothing about defence. Vierling's the center fielder. Handing center to Outman or a rookie is a real cost and none of the arithmetic above can price it. If Vierling's glove is worth half a win out there, most of my "he costs nothing" disappears.
• A team-level fit used on 1 player pretends to be more precise than it is. That r-squared of .830 is across 30 teams and thousands of plate appearances each. Pointing it at 176 plate appearances from 1 man gives you a number with a decimal point and not really that much behind the decimal point.
• Greene's rate assumes he plays every game he's available for. He wouldn't have. So 1.20 is a bit high.

What the last 2 weeks actually looked like

Here's the thing I keep going back and forth on. Since Carpenter went down on July 27, Detroit's played 14 games and gone 9-5, scoring 7.43 runs a game. Before that they were at 4.20.

That's a huge number and I don't believe it means much. It's 14 games, and it includes 14-0 and 13-1 and 11-0 and 11-0 again, so a couple of blowouts are carrying most of it. Nobody should walk away thinking the Tigers are better without their outfielders. What it's decent evidence of is the narrower thing: the offence has not fallen over without Carpenter and Vierling, and it had 14 games to.

Where this leaves them

59-61, half a game back of Texas for the last spot and level with Minnesota, 42 to go, with 6 teams inside 2 games of each other. It's about as tight as it gets.

And that's the part that keeps me from filing this under "no big deal." A quarter of a win sounds like nothing, and in a normal August it is nothing. In a race where 6 teams are separated by 2 games, a quarter of a win is a real slice of what's left. The injuries aren't a disaster and the panic version of this story is wrong, but "it's small" and "it doesn't matter" aren't the same claim, and in this race they come apart.

If Greene's back around the 22nd and Carpenter's foot finally settles down, this is a footnote. If the hamstring turns into 6 weeks, the number to be scared of is 1.2 wins, and Detroit doesn't have 1.2 wins to give away.
