This article has been updated since initial publication to reflect developments in the diagnosis of Trevor Story’s right elbow.

Surrendering first place to the Dodgers, as the Rockies did on Monday night in Los Angeles, was bad enough. The departure of Trevor Story in the middle of his fourth-inning plate appearance may prove more damaging to the team’s postseason hopes. Via Twitter, The Athletic’s Ken Rosenthal reported on Tuesday afternoon that the All-Star shortstop is “facing potential UCL damage in [his] right elbow,” though the exact diagnosis was unknown at the time. In the wake of an MRI, the Rockies now believe that Story is dealing with inflammation in the elbow but no structural damage to the ligament. Had there been significant UCL damage, the 25-year-old shortstop would likely have been headed for Tommy John surgery, ruling him out of the remainder of the regular season and postseason (if the Rockies make it), and into the first half of next season. The Rockies are optimistic that he will miss “only a few days,” though his absence could potentially be a significant blow to the team’s playoff hopes.

Story reportedly felt a twinge in his elbow after making an outstanding play in the first inning on Monday night. He dove to his left to stop a Justin Turner grounder, then he completed a spin and made a strong throw to first base for the out. His discomfort worsened when he whiffed on a 2-1 Hyun-Jin Ryu changeup in his next plate appearance.

Trevor Story has always been a good hitter. He’s never been as good of a hitter as he is now. In his third big-league season, the 25-year-old Colorado Rockies basher is slashing .291/.346/.555 with 40 doubles, five triples, and 33 home runs. In short, he’s been a beast.

According to Story, he hasn’t changed all that much mechanically since the Rockies took him 45th overall in the 2011 draft out of an Irving, Texas high school. But he has changed a little.

“I think you’d see something very similar (if you compared then to now), but there are some differences,” Story told me earlier this summer. “I had more of a leg kick when I was younger, and I was kind of bouncing my hands instead of resting them on my shoulder. Outside of that, my movements are basically the same.”

Story felt that having a higher kick resulted in him getting beat by fastballs from pitchers with plus velocity, and as he “didn’t really need a leg kick to hit the ball far,” he changed to what he considers “more of a lift than a kick now; it’s almost more of a hover.”

Leg kicks — ditto lifts and hovers — are timing mechanisms, and as not all pitchers are the same, nor is Story always the same. The differences are subtle, but they’re definitely there. Read the rest of this entry »

German Marquez is on quite the run. In the second half of the season, Marquez’s 2.3 WAR ranks third in all of baseball among pitchers behind only those marks recorded by Jacob deGrom and Patrick Corbin. His 2.29 FIP and 2.79 ERA since the All-Star break are both fantastic. He’s struck out nearly one-third of the batters he’s faced with five times as many strikeouts as walks. He’s doing all of this while pitching his home games in Colorado, and he’s just 23 years old. That’s quite the dramatic turnaround for a pitcher who put up a 4.73 FIP and a 5.53 ERA in his first 16 starts of the 2018 season. Like many young pitchers with a boatload of talent, Marquez has spent his first few years in the big leagues experimenting with different pitches and usage patterns. He seems to have found one that works.

A year ago, Marquez was primarily a fastball-curveball pitcher. He would mix in a change every now and again, and he did experiment with a slider, but it wasn’t used often and it stayed up in the zone. With a mid-90s fastball and good curve, Marquez produced a 21% strikeout rate, 7% walk rate, and an ERA and FIP in the mid-fours. In Coors Field, those still represented above-average numbers. For Marquez to progress, however, he was going to need to develop a third pitch. When Eric Longenhagen discussed Marquez ahead of the 2017 season, he anticipated the introduction of that third pitch.

Marquez also has a plus curveball in the 76-81 mph range that has a slurvy shape to it but bites hard and has solid depth. A back-foot curveball is the best weapon Marquez has against left-handed pitching right now, as his changeup is still below average. But Marquez is just 21 and his delivery is loose and fluid so there’s likely more coming from the changeup. Marquez’s command elicits similarly bullish projection because of the delivery and athleticism and he’s already throwing plenty of strikes. He’s a relatively low-risk mid-rotation arm, an above-average major-league starter.

Longenhagen mentioned the change as a potential addition, and Marquez did work to make that change more of a weapon heading into this season. That plan hasn’t exactly worked out. Marquez is throwing the changeup under 10% of the time this season. Even against lefties, he’s turned to it on just 11% of all occasions. What’s improved most for Marquez is the slider, and it is fooling hitters. Here’s Nick Hundley swinging at a slider despite holding a 2-1 advantage in the count:

The pitch works well in and out of the zone. When he throws the slider outside the zone, Marquez induces swings around 40% of the time, and batters swing and miss on two-thirds of those attempts. When the pitch is in the zone and batters swing, they make contact roughly 80% of the time, but on 44% of sliders in the zone, the hitter doesn’t bother to swing, like Evan Longoria in this 0-2 count.

There was a time at which FanGraphs got swept up in Trevor Story mania. FanGraphs, of course, wasn’t alone in how it responded to Story’s big-league debut, because back in April of 2016, Story came out of the gate like a bolt of lightning. In his first-ever major-league game, he hit two home runs. To follow that up, he hit another. To follow that up, he hit *another.* And then he went deep twice in game number four. Story hit ten home runs that month, and he finished it with a slugging percentage of .696. It was impossible not to sit up and notice.

But there are debuts, and then there’s the rest. Many players have come up and done well at first. Fewer have sustained their success. The key to sticking around is to adjust to the opponents’ adjustments, and from May 2016 through the end of 2017, Story managed a combined 93 wRC+. Playable, certainly, yet hardly fantastic. Story was in danger of being forgotten, and, worse than that, he was in danger of being supplanted. Maybe not right away, but Story had to prove he should be considered a part of the Rockies’ longer-term core.

Here we are today, and by any measure, Story’s been one of baseball’s best shortstops. The Rockies are in first place in the NL West, and while their run differential is far worse than that of the Dodgers, Story has obviously done his part. He’s helped to push the Rockies into their present position, and all it’s required is an improvement for the record books.

Bobby Wilson has caught for 16 seasons — nine of them at the big league level — so he knows pitching like the back of his hand. Particularly on the defensive side of the ball. With a .577 OPS in exactly 1,000 MLB plate appearances, the 35-year-old hasn’t exactly been an offensive juggernaut. But his stick isn’t why the Chicago Cubs acquired him from the Minnesota Twins this past Thursday. They picked him up for his receiving skills and his ability to work with a staff.

The quality and style of pitching he’s seeing today aren’t the same as what they were when he inked his first professional contract in 2002.

“The game is ever evolving, ever changing,” Wilson told me a few weeks ago. “I’ve seen it go from more sinker-slider to elevated fastballs with a curveball off of that. But what really stands out is the spike in velocity. There’s almost no one in this league right now who is a comfortable at bat.”

In his opinion, increased octane has made a marked impact on how hitters are being attacked.

“If you have velocity, you can miss spots a little more frequently, whereas before you had to pitch,” opined Wilson. “You can’t miss spots throwing 88-90. If you’re 95-100 , you can miss your location and still have a chance of missing a barrel. Even without a lot of movement. Because of that, a lot of guys are going to four-seam, straight fastballs that are elevated, instead of a ball that’s sinking.”

But as the veteran catcher said, the game is ever evolving. He’s now starting to see more high heat in the nether regions of the zone, as well. Read the rest of this entry »

As I write this, there are 115 different pitchers this year who have thrown at least 100 innings. Among them, Kyle Freeland ranks tied for seventh in ERA-, at 62. The pitcher with whom he’s even: one Clayton Kershaw. The next pitcher down the list: one Justin Verlander. Now, we’re a site that loves its peripherals, and, indeed, if you sort by, say, FIP-, Freeland doesn’t look quite so good. But he still looks strong. According to a peripheral-based version of WAR, Freeland has been a plus. According to a runs-based version of WAR, Freeland is a viable candidate for the NL Cy Young.

I don’t hesitate to say that Freeland has been overlooked. He doesn’t get the attention of rotation-mate Jon Gray, because Gray throws that sexy power stuff, and he gets those sexy strikeouts. Freeland doesn’t do as much of the basic stuff that analysts look for, so he’s flown for this long under the radar. But if you’ll allow me some freedom here, I’d like to invoke a couple all-timer names. The images might be able to speak for themselves.

Notes on prospects from lead prospect analyst Eric Longenhagen. Read previous installments here.

Note from Eric: Hey you, this is the last one of these for the year, as the minor-league regular season comes to a close. Thanks for reading. I’ll be taking some time off next week, charging the batteries for the offseason duties that lie ahead for Kiley and me.

D.J. Peters, CF, Los Angeles Dodgers
Level: Double-A   Age: 22   Org Rank: 7   FV: 45+
Line: 4-for-7, 2 HR, 2B (double header)

Notes
A comparison of DJ Peters‘ 2017 season in the Cal League and his 2018 season at Double-A gives us a good idea of what happens to on-paper production when a hitter is facing better pitching and defenses in a more stable offensive environment.

Reports of Peters’ physical abilities haven’t changed, nor is his batted-ball profile different in such a way that one would expect a downtick in production. The 2018 line is, I think, a more accurate distillation of Peters’ abilities. He belongs in a talent bucket with swing-and-miss outfielders like Franchy Cordero, Randal Grichuk, Michael A. Taylor, Bradley Zimmer, etc. These are slugging center fielders whose contact skills aren’t particularly great. Players like this are historically volatile from one season to the next but dominant if/when things click. They’re often ~1.5 WAR players who have some years in the three-win range. Sometimes they also turn into George Springer.

Performances from 8/26

Evan White, 1B, Seattle Mariners
Level: High-A   Age: 22   Org Rank: 2   FV: 45
Line: 3-for-4, 2B, 3Bho

Notes
We now have a full season of data to help us figure out whether Evan White’s weird profile is going to play. A plus-running backwards guy (bats right, throws left, a generally unfavorable combination due to the defensive limitations and platoon issues caused by both) who plays plus defense at first base, White was slugging .391 at the start of August, which is rather uninspiring for a college hitter in the Cal League. In August, however, White has 30 hits in 90 plate appearances and is slugging .763. He has made subtle changes to his lower half, drawing his front knee back toward his rear hip more than he did at Kentucky, and taking a longer stride back toward the pitcher. White is more often finishing with a flexed front leg, which has helped him go down and lift balls in the bottom part of the strike zone by adjusting his lower half instead of his hands. It’s a more athletic swing that was implemented before White’s explosive August, though he may just be getting comfortable with it now. Read the rest of this entry »

Yesterday, Jeff Sullivan wondered aloud why the Rockies, a contending club that would benefit from some offensive help, hadn’t taken any steps to address a pretty clear weakness. Today, Colorado responded by calling up a 38-year-old outfielder who couldn’t get a major-league deal this season. If nostalgia is your thing, the Rockies’ decision to bring back Matt Holliday is a clear winner. Whatever questions Sullivan had yesterday, however, likely weren’t cleared up by this most recent move. That doesn’t mean it won’t work, of course.

From a feel-good perspective, the move is a no-brainer. Below is a WAR leaderboard for position players in Rockies franchise history.

Holliday is one of the franchise’s greatest players, arguably the team’s best hitter of all time after Larry Walker. In 2007, Holliday hit .340/.405/.607 with a 151 wRC+ and 6.9 WAR, that last figure still the best a Rockies player has recorded since Holliday was traded to the A’s ahead of the 2009 season. He finished second in the MVP voting that year, was called safe at home, and won the NLCS MVP as the franchise advanced to their only World Series appearance. Holliday would go on to capture a title with the Cardinals, but as the place where his career started, Denver clearly has some significance to the outfielder.

The Nationals started to unload yesterday, making moves that, depending on your perspective, were either a few weeks too late, or a week and a half too early. It had been easy for a while to say the Nationals just needed time to come around, and our projections never really lost faith, but at some point a baseball team has to make up ground, and they were unable to get into a groove. There’s plenty to be written about what’s happened to the Nationals, but that might be better left for another day, or for another time when we can have a greater understanding.

The moves the Nationals made on Tuesday mean hardly anything for their future. It was more about just giving up on the present. And as far as the individual deals are concerned, you can see how Matt Adams should have a role on the Cardinals. Likewise, you can see how Daniel Murphy should have a role on the Cubs. And yet it was far easier to see how Daniel Murphy could’ve had a role on the Rockies. The Rockies being one of the teams with a higher waiver priority than the Cubs. Murphy wouldn’t have gotten to the Cubs in the first place had another team from the National League put in a claim, and while Murphy could’ve helped anyone, it sure seems like he could’ve made the biggest difference for Colorado. I don’t really know what they were thinking in allowing him to go by.
