Why would it be less necessary to employ shifts behind deGrom? In theory, because the purpose of the shift is to borrow from the positioning that converts poorly performed at bats into outs in order to better turn well performed at-bat into outs. And there simply isn't cause for that adjustment because there are so few well performed at bats against Jacob deGrom. Or alternatively — again, in theory — because equally distributing the amount of holes in your defense is to best prevent any but the most well struck balls from getting through. And nothing is being well struck. So why allow poorly struck balls tinkle through the massive holes that the shift creates?

Well, the data knows, to some extent: Of the 18 outs that Jacob deGrom recorded, 10 were by strikeout. It's theoretically possible that one or more of those strikeouts were aided by the batter trying to hit against the shift, but I wouldn't consider this particularly likely, as (a) people seem desperate enough just to make contact against the guy, and ( he throws almost no curveballs. Of the remaining eight outs, three were on pop flies caught by infielders. While, again, in theory, shift positioning could have aided in these circumstances, it seems pretty obvious that the best defense against infield flies is traditional defensing with the four infielders evenly distributed around the diamond. The circumstances where pops most typically succeed in dropping in against traditional defenses are the spots on the line directly behind the first and third basemen or in the triangle in front of the centerfielder. All three of the catches on these pops were, as fate would have it, executed by shortstop Francisco Lindor. None were in a position that a traditionally positioned shortstop wouldn't have gotten to it. https://metsrostercentral.files.wordpress.com/2021/06/screen-shot-2021-06-13-at-10.57.52-am.png> https://metsrostercentral.files.wordpress.com/2021/06/screen-shot-2021-06-13-at-10.55.15-am.png> https://metsrostercentral.files.wordpress.com/2021/06/screen-shot-2021-06-13-at-11.09.55-am.png> While those screenshots indicate where the ball came down, but not necessarily how long it was up, you'll have to take it from me that, while the third one was a flare off the handle with not a lot of time aloft, any Met shortstop I've ever seen — including Wilmer Flores but possibly excepting Ruben Tejada immediately following his broken leg — would have gotten to them from a traditional positioning, or a traditional positioning cheating one or two steps left or right. So that's 13 outs unaffected by shifting positively or negatively. Two more outs were executed by outfielders. While those indeed might have been affected by positioning, we're talking about infield positioning here, rather than outfield positioning. I'm happy to look more closely at them if necessary, but let's shelve them. So we're up to fifteen outs. One was our lone baserunner erased on a caught-stealing. No shift leaves secondbase completely unprotected from would-be stealers, so I think we can rule that as unaffected. Sixteen outs. The 17th out as we review (although the 18th chronologically) is a foul out to the thirdbaseman to end the top of the fifth. This is the semi-famous Villar-dancing-among-the-loose-baseballs putout. Let's look at that. [FIMG=600]https://metsrostercentral.files.wordpress.com/2021/06/screen-shot-2021-06-13-at-11.43.17-am.png[/FIMG] Villar has NOT shifted on this play, despite the switch-hitting Jurickson Profar batting from the left side. Again, you're not seeing the full play, but you probably remember it and it's not hard to conclude from this shot that he would have not gotten to this ball had he been in the shift. James McCann may have had a 50-50 shot, as the balls were rolling away from him. So while the shift might well have prevented this out, it certainly didn't make it more likely. So the effectiveness of the shift comes down to two ground-ball plays — the lone ground-ball out, and the lone ground-ball hit. This is very helpful. Interestingly, they came consecutively, and they both came in the secondbaseman's zone. The groundout was effected by Manny Machado. He hit a slow, high-hopper to the right of second. José Peraza, playing to the left of the bag, comes over and gets to it in plenty of time, and gets the surrendering Manny by four long strides.

But it's not 100% certainty to get to. It's kind of got just a little bit of up-the-middle-hole-ness against a traditionally aligned secondbaseman. Maybe a bad secondbaseman makes that play 85% of the time from a neutral position and 95% of the time with a two step cheat. I'm trying to err on the side of generosity toward the batter here. I made that play when I was 15, and more than once. It's certainly usually an out. The hit — righthanded Will Myers slap through the right side for the lone San Diego baserunner off of deGrom — was struck neither hard nor soft. In fact, it's probably on the softer side of the median. But it's certainly right at a traditional positioning point for a secondbaseman, and easy enough to get to for a secondbaseman cheating two steps toward the middle against a righty. Again, I'm using the Wilmer Flores standard here. This is an out for any team deploying something like traditional infield positioning (or possibly an error). Below shows the hit getting through, starting with the centerfield camera shot, followed by a shot from behind the catcher, and finishing with three shots from the overhead cam behind home plate.

So, given that data, it's certainly not a certainty that Jacob deGrom, backed by traditional defense, finishes the sixth inning with a perfect game intact, but it's certainly likely. Beyond that he may still take himself out of the game even with a perfecto. I suspect he doesn't, but what do I know? And it's diddling over one hit. How selfish does that make me? I get a glorious game, but it's perfection I want. But again, traditional defense and perfection is more likely, at least on Friday night. Yeah, so what? It's one game. Eighteen batters worth of data doesn't suggest that the shift has given away more than it has taken, But it certainly is enough to indicate to me that further inquiry is warranted, and maybe traditional defense will get him further.
