Some months ago, we moved our internal communications platform from Yammer to Slack. That part shouldn’t interest you, but I just had to explain where this screenshot of a direct message came from:

August is a good guy. So who am I to deny his request?

I remember I first started thinking about the relationship between velocity and batted-ball angle during Michael Pineda’s rookie season. I was probably trying to explain a low home-run rate or something, and that’s when it came to me — Pineda threw hard, and because of his size, it looked like he threw even harder. Wouldn’t it make sense that hard throwers would be more difficult to pull? And it tends to be those pulled fly balls that do the most damage. As a pitcher, you want air balls going the other way. They frequently suck.

When I thought about this stuff back then, it was mostly theoretical. Didn’t have many numbers. We’ve come a long way. There is a relationship between angle and velocity. It’s not perfect, but it’s real, with the pattern you’d expect.

When Adam Dunn posted his 190th strikeout in 2004, he broke a record originally set by Bobby Bonds over 30 years earlier, in 1970. While it took some time for Bonds’ mark to be surpassed, it’s become a common occurrence in the meantime. Indeed, including that one produced by Dunn, there have now been 18 player seasons that have met or exceeded Bonds’ previous high.

While Bonds’ strikeout distinction has been exceeded on a number of occasions, there’s another one that remains untouched. Since Pete Incaviglia’s 1986 season, his mark of 185 strikeouts has endured as the record for rookies. Not a single rookie has come within even 10 strikeouts of Incaviglia’s record. Tampa Bay outfielder Steven Souza looks poised to make a run at the record this season, however.

Souza has followed an interesting track to the majors, spending eight years in the Washington Nationals’ minor-league system before getting a shot as a full-time starter with the Rays this season. Souza, a part of the trade that sent Wil Myers to the San Diego Padres, hit very well in the minor leagues over the last few years. As Carson Cistulli noted after the trade, through no fault of his own, Souza found himself behind Jayson Werth, Bryce Harper, and Denard Span making it difficult to receive a promotion to the big leagues. In Chris Mitchell’s profile of Souza, he reinforced the same point, writing:

Yes, Souza has been old for his level for years now, but the “old for his league” caveat means less and less the closer a hitter gets to the majors. And when a hitter performs like Souza did in Triple-A, you absolutely have to take notice. More often than not, hitters who rake in Triple-A turn into serviceable big leaguers, regardless of how old they are.

The Rays saw this logjam and pounced, providing the team with a player to replace the departed Myers while also securing other players in the deal as well. Despite Souza’s age relative to other prospects, Kiley McDaniel rated him the 52nd best prospect in Major League Baseball heading into the season. For the Rays, the move seems to have worked out in the early going. Read the rest of this entry »

Eduardo Rodriguez’s big-league debut went about as well as anyone could have expected. The hard-throwing lefty struck out seven in 7.2 scoreless innings, and allowed a mere three hits. Boston’s original plan was for Rodriguez to make just one spot start before returning to the minor leagues. However, following Thursday’s outing, the Red Sox decided they’d go with a six-man rotation for the time being in order to give Rodriguez at least one more start. They apparently saw enough to keep him around.

The thing that stood out most about Rodriguez’s debut was his crazy-hard fastball. As Eno Sarris noted on Friday, Rodriguez threw his fastball harder than almost any active starting pitcher. In fact, his average fastball velocity from last Thursday night was the highest we’ve seen from a lefty starter this year. Read the rest of this entry »

Last year’s first-overall draft pick, left-hander Brady Aiken, didn’t come to terms with the Astros because of a difference regarding what the physical showed about the condition of his elbow, despite being healthy at the time. Aiken went to IMG’s Post-Grad team this spring, but only threw a handful of pitches before he left his first game with an elbow injury, eventually leading to Tommy John surgery weeks later.

Since the failure of Aiken and Houston to reach an agreement, there’s been lots of buzz as to what the latter saw in that physical, since they’re the only team to have seen it. The most common rumors are unusual situations with the size of Aiken’s UCL, the blood flow to that area and the bone structure around the elbow.  His draft stock for next week’s draft ranges anywhere from the middle of the first round to the middle of the second round, depending on how much truth there is to these rumors.

A few days ago, the Aiken camp made his medical information available to teams, but with a very rare set of conditions about who can see it. Sources indicate the information is available only to GM-level personnel or higher (who can then distribute it to other decision-makers within the team) and the GM has to make a specific request with Aiken’s camp to see it, which the Aiken camp then has accept.

For the better part of the last decade, Gerrit Cole has intrigued with potential. Twice a first round selection — after being drafted out of high school in 2008, he spurned the Yankees and went to UCLA instead — and the first overall selection in the 2011 draft, Cole’s velocity and frame have had scouts dreaming about what he could eventually turn into. But while the stuff has always been top-shelf, the performance haven’t always lined up with expectations.

In his final season at UCLA, in fact, he wasn’t even his own team’s best pitcher, as Trevor Bauer ran circles around him from a performance standpoint. Their lines, side by side:

Cole looked like an ace, but Bauer was the guy who pitched like one, striking everybody out in a way that you’d expect Cole to do, given his velocity and breaking ball. But the Pirates bet on his stuff and their ability to develop him into more than what he had been, choosing Cole with the top pick while Bauer went to the Diamondbacks three selections later.

In the minors, it was a bit more of the same, as he was good-but-not-great, and certainly wasn’t blowing away minor league hitters like you might expect for a top overall selection who throws 100 miles per hour. And when he got to Triple-A, the strikeouts mostly disappeared, as he managed just 63 strikeouts in 90 innings at the highest rung of the minor league level. He was still throwing hard, and still had a good breaking ball, but for whatever reason, batters were still making plenty of contact against him, and he’s never profiled as an elite command guy, so missing bats was always going to be his path to star status.

Things got a bit better after the Pirates promoted him to the big leagues, as his strikeout rate jumped to 21% in 2013 and up to 24% last year, but given that the league average strikeout rate in the majors is now 20%, these are still not dominating performances. And while Cole’s FIP-inputs suggested he was pitching fairly well, he posted an ERA just a bit below league average, as he allowed a .310 BABIP despite pitching for a team that shifted very aggressively and held opponents to a .287 BABIP overall. Heading into 2015, Cole remained more potential than performance, and at some point, he was going to have to do something to justify the belief that he could become an ace.

That point is here, and through the first two months of 2015, Cole has now become what people have been projecting him to be. A comparison of his 2013-2014 and 2015 lines, to highlight the changes:

Recently, one of the hot topics in baseball statistics has been the appearance of a measurement for hard-hit balls: here at FanGraphs, we added hard-hit rate to our leaderboards before this season, adding along with it a wealth of opportunities for analysis. An issue with any new statistic is that it can be cited without fully knowing its true use or impacts, and so hard-hit rate has been making the rounds in player analysis, generally cited in respect to how well or how poorly they have been performing.

For hitters, it might go without saying that hitting the ball harder is generally a good thing: the aim of hitting, in a certain sense, would seem to be to hit the ball as hard as possible as often as you can (except in the cases of bunting or other situational circumstances). However, it hasn’t been clear yet how hitting the ball hard impacts other rate and counting statistics, and that seems to be a hole in our understanding of a statistic that is undergoing a moment in the spotlight.

The aim today is, at the very least, to explore how hard-hit rate impacts a few of those stats, as well as to begin a conversation that more astute statistical minds may be able to take to deeper and exciting places. There are a couple levels to this piece today, but there are surely many more that I have not reached: I don’t intend to make hard conclusions, but rather to explore and provide a well-intentioned foray into the data. With that said, onward.

People have jobs and dogs and maybe kids and they sometimes drink beer (the people not their kids) (hopefully) so sometimes it’s tough to keep up with all the innovations going on in the baseball statistical community. One thing that used to be easy to keep up with though is the value of spring training stats, which we long thought to be as meaningless as anything uttered by a six-year-old whether they’ve had beers or not. There are so many factors that go into the steady playing field that is a Major League Baseball season that are not present during spring training, including player quality, opponent quality, physical condition or lack thereof, the extremes of the playing environments in Arizona and Florida, and so on, that it’s a wonder they even call it baseball. That’s what I’ve long held to be true. Way back in 2010 our Dave Cameron wrote on this here site that spring training stats are worthless. To quote him specifically, Dave wrote, “…spring training numbers just don’t mean a thing. At all. Anything.” I’m getting a tattoo of that right above the giant eagle with the banner reading ‘There is no such thing as a bitching prospect.’ Always double confirm your tattoos before sitting, friends.

Since Dave’s piece was published, some studies, including here at FanGraphs, have showed that on-field success or failure in certain categories, such as strikeout rate (K%) and walk rate (BB%) for pitchers, during spring can foretell the same type of success during the regular season. This makes some sense as batting is reacting, so the quality of the batting would, in theory, heavily depend on the quality of the pitching, but pitching is an action not dependent on anything but itself. The quality of hitters will impact it, but a well-executed slider isn’t likely to be hit by anyone, regardless of whether they’re a major league regular or an org lifer in spring training to fill out the roster.

To be fair to Dave, he was talking about home runs and batting average, which are two traditional stats whose predictive value from spring training remains largely moot. Still, that there is some nuance to the whole value of spring-training stats is, to me at least, surprising, given all of the above. This past spring, March 31 to be exact, our Eno Sarris noted that strikeout rate for hitters stabilizes at around 100 plate appearances, and that because some hitters achieve that number of plate appearances or more during spring training that it might be worth keeping an eye on. He then created a leaderboard listing the hitters who cut their strikeout rates down the most during 2015 spring training when compared to the 2014 season, then he highlighted seven of those players. You can see his complete list here, but I think the list of seven players is worth revisiting to see if the players’ predicted progress is progressing through two months of action. So I did! And you’re reading it right now!

Most Highly Rated Game
New York AL at Seattle | 22:10 ET
Sabathia (60.1 IP, 90 xFIP-) vs. Montgomery (MLB Debut)
One’s interest in this game — as opposed to the Toronto-Washington one, for example, featuring Max Scherzer — depends largely on one’s interest in Seattle left-hander Mike Montgomery. Acquired by the Mariners from the Rays at the end of March — and acquired by the Rays before that in the deal that sent James Shields to Kansas City — Mongtomery appeared three times among the top-50 prospects on Baseball America’s annual list. The last such appearance occurred in 2012, however, and the now 25-year-old left-hander has produced pretty ordinary results in the high minors since then. This year the numbers are more promising, though. Over nine starts and 53.0 innings for Triple-A Tacoma, Montgomery has produced strikeout and walk rates of 21.8% and 6.9%, respectively, while all signs indicate that he still possesses the above-average fastball cited by Kiley McDaniel this offseason. The combination of performance, physical tools, and pedigree conspire to produce not only an unintentional burst of alliteration but also some interest wherein Montgomery’s near future is concerned.
