Trevor Story was one of the great surprises of 2016. He continues to be of interest early in 2017.

Story has always been a fly-ball hitter, which is an attractive trait for a player who calls Coors Field home. In his eight minor-league stops, Story hit more fly balls than ground balls six times. As a rookie last season, he posted a 0.62 GB/FB ratio and a 47.1 FB%.

This season?

Story has gone full Schimpf on us. He ranks second only to Schimpf in GB/FB ratio and second in GB/FB ratio (minimum 100 plate appearances) since batted-ball ratios have been recorded.

Story was already an extreme fly-ball hitter. Now he’s even more extreme — nearly the most extreme on record.

Story’s proclivity for fly balls doesn’t appear to be the result of fluky, early-season sample size. Consider: his average launch angle is 32 degrees, nearly double his 2016 average (16.7 degrees). A number of batted-ball metrics are near stabilization points. In the majors, Story ranks second only to Schimpf (33.1 degrees) in average launch angle. I haven’t seen any reports on Story’s apparent swing alterations or changes to philosophy early this season, but it appears as though he’s up to something.

We’ve written quite a bit about the uppercut philosophy this spring, and more and more MLB hitters appear to be buying in. The league’s average launch angle has inched up from 10.0 degrees in 2015, to 10.6 degrees in 2016, to 10.9 in 2017.

The question is, when does a hitter become too extreme in approach?

A tough thing about analyzing pitching is that it’s a moving target. You can get a decent sense of what a pitcher is like right now, and then he can completely change his approach over the next month and become a different pitcher. There’s evidence of this in the data: a pitcher’s exit velocity becomes stable relatively quickly, but then that stat’s predictability doesn’t actually improve as the sample increases. In other words, you can see what the pitcher’s got now, but what about tomorrow? Ask us then.

This is all relevant to Tyler Chatwood. You might have thought you had an idea of who he was as a pitcher — great sinker, uses his four-seamer for whiffs, and doesn’t have great secondary stuff, so it’s all about the ground balls. That’s who he was! It isn’t who he is right now, though. I had to ask him about who he is right now when I had the chance.

Take a look at Charlie Blackmon’s defensive charts and you’ll notice that he has a good side, one where he’s made a higher percentage of catches than the other. On the one hand, that seems strange: humans are largely symmetrical creatures. On the other, maybe it makes perfect sense: most people have dominant hands and eyes and move better in certain directions.

Nowhere is the latter point more painfully clear to me, personally, than on the basketball court. As much as I practice going to my left, I usually do something very silly when I attempt the feat in a game. If I get to the left and actually get to the hoop, my mechanics fall apart when I get there, and I end up doing a strange thing with my right hand that leads to cuss words more often than points.

So when I saw this map for Blackmon, I figured it was all about that first step. See those hits over his left shoulder that are colored blue? Those are relatively high-percentage catches that have fallen into play against him. Must not be stepping well in that direction, I figured.

But when I asked the outfielder about those hits and his first step, he laughed. First, he thanked me for highlighting his shortcomings. Then he said something surprising — “I prefer the ball to my left,” he said. “There’s something I don’t like about running towards a ball to my right.”

I got asked the question in my chat this week. Dave also got asked it in his. What do you do to solve Byron Buxton’s problems at the plate? This is essentially the question. People want to know. The answer, to me, is you let him play. It seems that we get these questions each April about a phenom struggling in his first taste of a full major league season. So while I’m writing this piece with Buxton in mind and as the lead example, it is also sort of universal.

Daily notes on prospects from lead prospect analyst Eric Longenhagen.

Mike Soroka, RHP, Atlanta (Profile)
Level: Double-A   Age: 19   Org Rank: 9  Top 100: 93
Line: 5 IP, 2 H, 0 BB, 2 H, 7 K

Notes
Soroka is the most polished strike-thrower of Atlanta’s young arms and has mature competitive poise. Much was made of his aggressive assignment to Double-A, but this was a promising start.

In 2015, Chris Rusin made 22 starts for the Colorado Rockies in what was a lost season for the ballclub. They finished in last place for the third time in four seasons, and their attendance dropped to its lowest mark in eight seasons. The club possessed a promising cache of prospects. Regardless, one couldn’t be blamed for feeling pessimistic about the Rockies’ future.

Fast forward to today, and Rusin is still with the team. Instead of working in a starting capacity, though, he’s been moved to the bullpen. And rather than occupying a large role in Colorado’s rotation, he’s not even a sure thing to serve as the club’s sixth or seventh starter.

This isn’t a product of Rusin’s failings, however. He was actually pretty good last year, recording an 83 xFIP- and 76 ERA- in 84 innings of starting and relief work. Rather, the change in Rusin’s role is emblematic of a new development in the organizaion — namely, that the Rockies suddenly have a great deal of pitching depth, both in the rotation and the bullpen.

Let’s start with the most recent starting pitcher to make his major-league debut for the Rockies, Antonio Senzatela. After showing well in 2015 in his first trip through the California League, Senzatela had a very trying 2016 season. First, he missed time due to a shoulder injury. Then, his mother died from cancer back home in his native Venezuela. At the time, the Rockies used his shoulder injury as cover to let him go home and spend time with his family, which isn’t only an understandable but commendable move by the organization. But for those tasked with determining how Senzatela would stack up as a prospect heading into this season, it certainly created uncertainty, as any season-ending shoulder injury normally would. He’s still not very projectable, but he might have snuck on to the back end of Rockies’ team lists had people known why he really missed the latter portion of the season.

Fast forward to 2017, and Senzatela’s major-league debut was certainly promising. Despite hitting Keon Broxton in the face (Broxton fortunately seems to have come away from the HBP unharmed), he was otherwise brilliant on the day, striking out six batters through five scoreless innings. The result was a Game Score of 66 — and a Game Score v2 of 66 — which is pretty good for a Rockies pitcher making his major-league debut. Take a look:

Now, some of this is damning with faint praise. The Rockies haven’t had a ton of good starting pitchers, and even fewer who turned in good debuts. But it’s better than the alternative, which would have been getting rocked. Senzatela’s outing is tied for third in terms of Game Score, and by itself in sixth place according to Game Score V 2.0. Not too shabby.

It’s opening day, and things can be weird, so let’s quickly check some Brewers and Rockies readings. Junior Guerra‘s fastball today averaged a little over 92. Last year, it averaged a little over 93. Tommy Milone‘s fastball today averaged a little over 88. Last year, it averaged a little under 88. Nothing crazy yet. Scott Oberg‘s average fastball matched up well with last year’s mark. Jon Gray’s average fastball seems up a few hairs from last year. There’s adrenaline in the first game of the season. I think we’re okay to proceed.

Let’s proceed!

That’s a slider. If I could just-

But could-

There’s no w-

Jon Gray threw a very good slider last season. According to the run values we have on the leaderboards, out of all starting pitchers, Gray’s slider ranked 14th-best, at 13.9 runs above average. He was in between Carlos Rodon and CC Sabathia. Here are the fastest average sliders thrown by starters:

Hey look, it’s Gray! Gray is no stranger to having velocity. He pumps his fastball into the mid-90s with regularity. The slider, last year, was something. On Monday, according to Gameday, it averaged 90.9 miles per hour. That’s right where 2016 Syndergaard sat. Granted, Syndergaard also pitched Monday, and this time his slider averaged 91.6. No pitcher should make a habit of trying to chase Noah Syndergaard, because that’s a competition you’re going to lose, but Gray was just flinging Syndergaard-esque breaking balls in between heaters, and this would take some getting used to. Unsurprisingly, going up against the Brewers, Gray was completely dominant.

And then things came off the rails in the fifth and Gray wound up with an 11.25 ERA. Surprise! It’s baseball! This is what you missed about baseball. Or what you didn’t miss at all, even just a little bit.

Just today we kicked off our annual Positional Power Rankings series, which means that, before too long, we’ll get a couple of posts about individual bullpens, looking at every single group. I’ll even be responsible for writing one of those posts, meaning maybe it works to our disadvantage to put this post up now, focusing on one bullpen in particular. But I’ve had a note here for a while, and I’m not one to let a topic go uncovered. The Rockies bullpen is of particular interest, especially at a time when the larger narrative around the team has responded negatively to recent news.

Let’s rewind. Yes, the last week or two have not been kind to the Rockies organization. The outlook for the season ahead has certainly gotten worse. Yet going back to last season, you know which team’s bullpen had — easily — the league’s worst WPA? That would be the Rockies, who made even the Reds feel proud of themselves. Although the Rockies finished at 75-87, their BaseRuns record was a more decent 80-82. With a stronger bullpen, last year’s Rockies would’ve been an average team. Their bullpen this year has the potential to be unusually dominant.

A team can’t make their season in March, but they can lose their season before it begins. Last week was an awful week for the Rockies.

At the moment, the Rockies and the baseball world aren’t concerned about when Chad Bettis will pitch again. They just want him to be healthy, after the 27-year-old starting pitcher learned last week that his testicular cancer had unexpectedly spread. Bettis was declared cancer free back in January.

From Nick Groke’s story in the Denver Post:

His prognosis for a healthy recovery is good, in the 90 percent range, he said. Bettis will start chemotherapy treatment in Arizona sometime soon. And he and his wife Kristina are expecting their first child later this month.

But Bettis’s return to baseball this season is in doubt. “Optimistically? This year,” Bettis said. He was given a broad timeline of potential outcomes.

“You never know how these things will unfold. From our standpoint, we’ll have to make some adjustments,” Colorado manager Bud Black said. “We feel good about what will happen. He will keep his chin up and his chest out and press forward.”

There’s no certain timetable for Bettis’s return, but he’s likely to miss a significant amount of time.

Adam Ottavino is a cerebral pitcher. You probably already know that, especially if you’re a regular reader of FanGraphs. Eno Sarris and I have both talked to, and written about, the Rockies reliever multiple times in recent seasons. From spin rates to spin axis to release points, he digs deep into data in search of any and all advantages he can find.

Last week, I approached Ottavino at Colorado’s spring-training facility — the scenic-and-pristine Salt River Fields at Talking Stick — to get a pitcher’s view of how launch-angle studies could end up impacting the game. His answer, studious as always, segued into the optimization of his own offerings.

———

Adam Ottavino: “It’s going to be a natural, evolutionary process. People are going to change what they’re doing at the plate and, as pitchers, we’re going to have to change in response to that. They’re trying to get on plane and create fly balls, staying through it really well. I think we’re seeing more guys now with the ability to lift lower pitches. In years past, the swing wasn’t really designed to do that. They were trying to hit the ball on the ground, hard, and run.

“I think we’re going to continue to see pitchers elevating. We’re going to continue to see pitches designed to turn those fly balls into weak fly balls. But I think until it’s fully embraced — the uppercut swing, and all that — until it’s prevalent throughout all of baseball, it’s hard to imagine we’ll see a major trend on the pitching side in response to that.
