As the battle for a handful of playoff spots intensifies in both leagues, we today complete our late-season look at MLB park factors. Earlier this week, it was the American League; today, the senior circuit. These park factors, as explained in previous installments, are based on granular batted-ball data, such as exit speed and launch angle.

As a reminder, here’s the quick-and-dirty on the method used to calculate these park factors. Through August 21, 106,962 balls were put into play during MLB regular-season contests. They resulted in an overall batting average of .328 and slugging percentage of .537, while fly balls generated a .328 AVG and .895 SLG. Line drives generated a .661 AVG and .872 SLG, and ground balls a .237 AVG and .258 SLG. (Oh, and pop ups have generated a .018 AVG and .028 SLG.) Each BIP type was split into “buckets” separated by 5-mph increments. The top fly-ball bucket begins at 105 mph, and the top liner and grounder buckets begin at 110 mph.

For each ballpark, the actual production derived from that park’s actual BIP mix was compared to the projected production, assuming that each BIP bucket generated MLB average production for that BIP type/exit-speed combination. Convert everything to run values, and voila, park factors, both overall and by BIP type.

This is a series of scouting thoughts on high-school prospects eligible for the 2017 MLB Draft based on observations from summer showcases. Today’s positional group is corner infielders. Links to other positional groups appear below.

Previous editions: Catchers / Middle Infielders / Center Fielders / Left-Handed Pitchers.

The position du jour is corner infielders. This is a weird group. I shuffled the names around quite a bit before publication and am still not sure that I’m okay with what I have because beauty is very much in the eye of the beholder when it comes to all of these prospects. Without further adieu…

Adisyn Coffey, 3B, Delta HS (IN)

Height: 6’2, Weight: 170, Commitment: Arizona State

Coffey had the coolest looking bat at Area Codes and put on quite a display with it, making hard, airborne contact in several at-bats. He has above-average bat speed and great feel for generating lift because of a cute little backside collapse that creates some uppercut in the swing without overdoing it and eating away at his ability to make contact. Coffey loads his hands quite high and it can take a good bit of time for his barrel to find the baseball in the hitting zone, but he moves the bat around pretty well, I like his chances to hit and, eventually, hit with some power.

A few weeks ago, I approached Tampa Bay (and former San Francisco) infielder Matt Duffy in the visiting clubhouse at Fenway Park. I wanted to talk to him about the mental side of the game. He was getting dressed, so we agreed to meet in the dugout in five minutes. At that very moment, Brian Kenny began talking about the idea of clutch on MLB Network, which was showing on the TV a few steps from where were standing.

Duffy kept his eyes and ears on the MLB Network discussion as he pulled on his uniform and cleats. With that in mind, I began our subsequent conversation with that very subject. From there, we segued into his mindset as a hitter, which is heavily influenced by Harvey Dorfman’s The Mental Keys of Hitting.

———

Duffy on clutch hitting and heart rate: “I think there is something to [the idea of clutch]. When you look at the RBI leaders every year — the guys who do well with runners in scoring position — for the most part it’s the same guys. To me, that’s not an accident. I think a lot of people think RBIs are purely a result of the opportunities you have. That does play into it, but I also think that, in certain situations, if I can keep my heart rate at a more efficient level than the pitcher does, more times than not I’ll succeed. I don’t want my heart rate to be so low to where I’m not awake, but I also don’t want it to be so high that I’m jumping at everything in the box.

We’ve all seen those swings so terrible that a batter can’t help but smile. Swings like this one from Brandon Phillips last year.

Phillips, of course, isn’t the only victim of this sort of thing. He’s been a league-average major-league hitter for a decade, which is a substantial accomplishment. But even accomplished hitters can look bad, can get it very wrong.

Were Phillips batting not for a last-place club but one contending for the postseason, we might gnash our teeth. Couldn’t he see that was a slider? What was he thinking? What was he looking at?

The answer to that last question, turns out, is way more complicated than it seems. Phillips clearly should have laid off a breaking ball that failed to reach the plate. He clearly has done that — otherwise, he wouldn’t have had a major-league career. So what happened? What did he see? Or not see? Ask hitters and experts that question, and the answers are vague, conflicting, and sometimes just strange.

All things considered, Julio Urias is having an extraordinary rookie year. In his age-19 season, Urias has struck out a quarter of all the batters he’s faced in 72 innings. He’s got a 3.50 ERA and a 3.25 FIP, and the list of starting pitchers, age 20 or younger, with better adjusted ERAs and FIPs over the last 50 years runs just six deep. ZiPS already sees Urias as being the near-equal of Cy Young candidate Masahiro Tanaka, and Steamer thinks even more highly of the Dodgers’ young phenom. Already, Urias has put himself on the map as one of baseball’s best young pitchers. And already, Urias is coming after one of teammate Clayton Kershaw’s crowns.

Devised originally in response to a challenge issued by sabermetric nobleman Rob Neyer, and expanded at the request of nobody, NERD scores represent an attempt to summarize in one number (and on a scale of 0-10) the likely aesthetic appeal or watchability, for the learned fan, of a player or team or game. Read more about the components of and formulae for NERD scores here.

Most Highly Rated Game
New York AL at Boston | 19:10 ET
Tanaka (186.2 IP, 82 xFIP-) vs. Rodriguez (88.0 IP, 115 xFIP-)
On the one hand, one finds that Boston currently possesses over a 60% probability of winning the AL East; New York, about just a 1% probability. Looking over into the other, second hand, however, what one also finds is that the Yankees (a) currently trail the Red Sox by just four games, (b) begin a four-game series against that exact Red Sox club today, and (c) appear to have the benefit of a favorable pitching matchup tonight. Owing both to their offense and home-field advantage, Boston still possesses a slight advantage in terms of the single-game winning projection for tonight’s encounter. It wouldn’t be particularly surprising for the gap between the clubs to shrink to just three games before tomorrow, however.

Baseball has a thing for archetypes. Leadoff hitters are supposed to be fast. Right fielders have good arms. Closers need either to be Mariano Rivera or slightly bizarre. These archetypes exist, in theory, because they are consistent with what you need from certain players. The rise of the analytics movement in baseball has fought against some of the ill-conceived archetypes, like the bat-handling No. 2 hitter, but many of these ideas remain because they align with success.

One straightforward example is that center fielders should be fast. Technically speaking, you just want a center fielder who can prevent hits over a large section of the field. There’s more than one way to possess that ability, obviously, but speed certainly helps, even if you could imaging a successful center fielder who didn’t run particularly well. Yet, in general, it’s a baseball archetype that seems to have stood the test of time.

This article is not going to challenge that belief. It is better to have a fast center fielder. But what this article is going to do is study and celebrate a particularly unusual data point relating to center fielders and speed. Marcell Ozuna is just weeks away from becoming the first center fielder since 2005 and just the 22nd ever to go an entire season without a stolen base.

In the eighth inning of Monday night’s game at Yankee Stadium, Yasiel Puig was asked to pinch-hit against a left-handed relief pitcher named James Pazos. With two outs, nobody on and the Dodgers already winning 6-2, the stakes weren’t terribly high. However, with Puig’s recent return from purgatory Triple-A, it was a good opportunity to give the right-hander an at-bat off the bench over the left-handed Joc Pederson. The result was the first pinch-hit home run of Puig’s career. However, beyond the actual outcome of this one at-bat, Puig’s pinch-hit performance served as a reminder of exactly how important he can be for the Dodgers in September and October.

The latest whispers and rumors indicate that, leading up to the August 31 waiver trade deadline, the Dodgers and Brewers were tantalizingly close to completing a deal that would have sent Puig to Milwaukee and Ryan Braun to Los Angeles. Reportedly, it’s a trade scenario that may be revisited this offseason. For now, however, Puig remains a Dodger. Whatever discord does or doesn’t exist between the player and team ought to be put on the back burner for now because the Dodgers have a role that needs to be filled and Puig is the one here to fill it.

There are a lot of different directions in which the Dodgers could go as they construct their postseason roster, but one of them includes taking the five pure outfielders currently with the team. Did you ever watch Sesame Street either growing up or with your own kids? You know that “One of these things is not like the other” song? Go ahead and sing it in your head while taking a look at the Dodgers five outfielders: Andre Ethier, Joc Pederson, Josh Reddick, Andrew Toles, and Yasiel Puig. (Yeah, that song will be in your head all day. Sorry.)
