It wouldn’t be wrong to say that Mike Napoli called Masahiro Tanaka an idiot on the baseball field. It would, of course, be misleading — Napoli didn’t say that to Tanaka’s face, and Napoli wasn’t asserting that Tanaka is some kind of moron. Napoli was simply gleeful, returning to the dugout Saturday night after breaking a tie with a ninth-inning dinger. Down two strikes, Napoli was pleased to see Tanaka throw him an elevated fastball, and Napoli knocked it out of the yard to right-center. Though the ESPN Home Run Tracker says the ball would’ve left just one of 30 stadiums under standard conditions, that one, presumably, is New York, and within a few minutes the Yankees lost. Dingers have been Tanaka’s one human side.

If you listen to Napoli, Tanaka was a fool for throwing a fastball. Obviously, according to results-based analysis, Tanaka was a fool for throwing a fastball, since that pitch ultimately was the difference in the game. There’s no question that Tanaka made a mistake in that he missed his spot and left the pitch up. But let’s think a bit about the sequencing. Did Tanaka make a mistake in going with the heat in a 1-and-2 count? Was Tanaka being an idiot, or did he get burned by a fine idea?

Each weekday during the minor-league season, FanGraphs is providing a status update on multiple rookie-eligible players. Note that Age denotes the relevant prospect’s baseball age (i.e. as of July 1st of the current year); Top-15, the prospect’s place on Marc Hulet’s preseason organizational list; and Top-100, that same prospect’s rank on Hulet’s overall top-100 list.

In this installment, I examine three interesting groundball prospects who most have probably never heard of.

Summary
Newell’s exceptional plane and solid slider have allowed him to carve up Low-A hitters.

What’s an “average” fastball velocity? This year, it’s 91.9 mph. Last year, it was 92.0 mph. In 2012, it was 91.8 mph. We could go back further, but since that’s all pretty consistent and this isn’t really going to be about how hard pitchers throw anyway, three years is fine. We can say that 92 mph is pretty much the average fastball speed in Major League Baseball.

So with that knowledge in mind, here’s what I wanted to know: what hitters have to deal with the most heat that’s at average and above velocities? And how do they handle it? Fortunately, we have Baseball Savant, so we can look at this pretty easily. With a minimum of 500 fastballs seen — for reference, Matt Carpenter and Brian Dozier have each seen over 1,200 total pitches, so 500 pitches would be fewer than half of what an everyday player would have received — there’s only three hitters who have seen at least 35 percent of pitches coming in at 92 or higher:

Summary
Glasnow continues to put up big numbers, though his rawness remains significant.

Dellin Betances made his major-league debut as a top prospect in 2011. Here’s how that went for him:

(via Baseball Savant)

You don’t need to know much about that chart to know that Betances was terrible. Beyond struggling with precise location, he struggled with general location, and he looked nothing like a pitcher a team would want to use. He had size and he had heat, but he didn’t have anything else, and there were signs he’d end up nothing but a bust.

In one sense, Betances is back. In another sense, he’s arrived for the first time. Betances now is excelling as a Yankees reliever, and the past no longer has much relevance. He’s changed some parts about his delivery. He’s changed his breaking ball. He’s changed his role, which is the most significant change of all. The things Betances has kept are his size and his heat, but the questions from the past aren’t the questions of today. I’m not sure today there are any questions.

Summary
O’Brien’s hanging in with the legendary Joey Gallo in the minor league home run chase, and he plays the most important position on the defensive spectrum, yet he falls behind the first tier of slugging prospects due to a variety of weaknesses.

In one way, CC Sabathia is having the best season we’ve seen him have in years. In another, much more real way, he’s having the worst season of his long and valuable career. Baseball is a weird game sometimes.

When you look at the current ERA standings, from worst to first, a few things jump out at you. (Yes, besides, “ERA is dumb,” because for the moment this is more about what has happened than what might have happened.) You see Kevin Correia and Ricky Nolasco showing absurdly low strikeout numbers (along with Kyle Gibson, the Twins have the three lowest K% pitchers, because Twins) and you understand that pitching to contact in front of a lousy defense might not result in runs being prevented. You see a lot of high BABIP (I see you, Homer Bailey’s .385), and guys who have had a disaster start or two that inflate the number (Bartolo Colon), and guys who either can’t miss bats (John Danks) or throw strikes (John Danks) and find that the end result is poor (John Danks). As it turns out, there’s a lot of different ways to allow runs to score in Major League Baseball.

You most likely heard over the weekend that Yankees righty Ivan Nova walked off the mound in the fifth inning of Saturday’s start in Tampa shaking his right arm, and now we know that he’s got a partially torn UCL in his elbow. While he’s yet to decide whether he’ll rehab or opt for surgery, this is the kind of thing that almost always, always ends in Tommy John surgery, and it seems more likely than not that we don’t see him again in pinstripes before mid-2015.

In and of itself, this is actually smaller news than it seems, if only because we all know by now that this is the year that elbows are popping at an alarming rate, with Nova — assuming he does choose surgery — becoming the 21st professional pitcher (including minor leaguers) to get a zipper this year alone. 14 of those are major leaguers. He is, depending on how you look at such things, only the fifth or sixth or seventh most accomplished of the afflicted. If you could make a starting rotation of 2014 Tommy John pitchers, he might not even be in it. (Why one would do such a thing is another question entirely. That rotation might still be better than Arizona’s, though.)

So this is really less about Nova than it is about what the Yankees will…  oh, hang on:

Two things, both from Wednesday. Before the first game of a Yankees/Cubs doubleheader, the YES Network broadcast was profiling scheduled starter Masahiro Tanaka. They, of course, had very positive things to say, and at one point, Al Leiter remarked, “what I like is that he’s attacking the zone.” No nibbling, with that guy. Aggressive, polished rookie.

Later, Wednesday night, I got an email from Dave Cameron, asking if hitters should just stand there with their bats on their shoulders, since Tanaka doesn’t throw strikes. Why not force him to come into the zone? Is he even able to come into the zone often enough?

Two analyses by two analysts of one pitcher on one day, arriving at basically opposite conclusions. Leiter said Tanaka attacks the zone. Dave said Tanaka doesn’t attack the zone. What’s going on here? It’s time to gush some more about Masahiro Tanaka.

Perhaps we should be used to this by now. Just four years ago, Craig Kimbrel was just some guy who walked more than 18 percent of the batters he faced. Now, he’s Craig Kimbrel. In the same timeframe, Drew Storen went from talented rookie set-up man to closer on a suddenly not terrible Nationals team. In their wake, young relievers like Kenley Jansen, Kelvin Herrera, Trevor Rosenthal, Addison Reed and others have taken the baseball world by various degrees of storm. And there was this Aroldis Chapman guy, too.

This season has been no different. Seemingly anonymous relievers have been springing from the figurative woodwork to capture spots on the top of various reliever leaderboards, most notably K% and velocity. Let’s meet some of them, shall we?
