Writing about baseball in April can be difficult. Things are happening, and the natural inclination is to want to talk about those things, but for most players, we’re talking about 20 or 30 plate appearances. A bunch of starters have pitched one game. Besides changes in velocity, there’s not much we can say about what has happened so far. The Diamondbacks and Twins are the best two teams in baseball right now, so yeah, it’s early.

But while samples are still tiny for players and teams, things tend to stabilize pretty quickly at the league level. And, not surprisingly, the first week of the season was filled with the two things MLB games are becoming known for; strikeouts and home runs.

KISSIMMEE, Fla. – Everyone wants to speak with John Hart.

On a sunny day in late March at the Braves’ spring-training facility, Hart is seated in the driver’s seat of an E-Z-GO golf cart near the nylon netting of the on-field cage during batting practice. He employs the cart to travel around the sprawling facility. He loves spending time at its back fields, where the game’s No. 1 farm system, according to Baseball America, resided this spring. But at the big-league field his ability to watch pre-game work is compromised by a constant flow of visitors.

Bo Porter, a front-office assistant, is seated next to Hart in the passenger seat of the cart when Charlie Leibrandt approaches and speaks with Hart about a recent golf outing. Several current Braves players approach, as does a reporter (me). He makes time for everyone. No one is hesitant to greet the club president. There’s no halo of space — or a sense of need for space — around him.

“I like people. I’m an encourager by nature,” Hart says. “I really am.”

Perhaps that’s the foundation of his success: availability and amiability. I spoke with Hart this spring in the midst of his third rebuild project as an executive. His first, in Cleveland, was a major success, and he later put pieces in place for a turnaround in Texas. All that eludes him in a professional career spanning nearly four decades is a World Series ring.

It’s quite possible that encouraging, enjoying people, listening, being approachable — that they’re all keys to fostering the sort of collaborative environment and innovation for which Hart is responsible. It was under Hart that pre-arbitration contracts were pioneered, along with the modern front-office structure, in the early and mid-1990s in Cleveland. The game’s first proprietary database was built there, and all those Ivy League GMs who are running the show these days? Hart started that trend, too. He’s the creator of something akin to baseball’s version of the Bill Parcells Coaching Tree, having hired an unparalleled number of front-office staffers who became general managers.

Said Braves general manager John Coppolella, whom Hart hired in Atlanta: “I think you can very easily make a case for John Hart to be in the Hall of Fame. If you think about the influence he’s had. There are, what, 10 GMs who have worked for him? He can really hand power to people.”

Below is an analysis of the prospects in the Houston Astros farm system. Scouting reports are compiled with information provided by industry sources as well as from my own observations. The KATOH statistical projections, probable-outcome graphs, and (further down) Mahalanobis comps have been provided by Chris Mitchell. For more information on the 20-80 scouting scale by which all of my prospect content is governed you can click here. For further explanation of the merits and drawbacks of Future Value, read this. -Eric Longenhagen

The KATOH projection system uses minor-league data and Baseball America prospect rankings to forecast future performance in the major leagues. For each player, KATOH produces a WAR forecast for his first six years in the major leagues. There are drawbacks to scouting the stat line, so take these projections with a grain of salt. Due to their purely objective nature, the projections here can be useful in identifying prospects who might be overlooked or overrated. Due to sample-size concerns, only players with at least 200 minor-league plate appearances or batters faced last season have received projections. -Chris Mitchell

Scouting Report
The story of Martes’s acquisition is well told. The effects of the deal are obviously still resonating atop Houston’s prospect list, but perhaps more significant is the way that deal changed the way complex-level ball is scouted. Since Martes was unearthed in the GCL, more and more scouts are being assigned to rookie ball in Florida and Arizona. Some clubs have scout(s) here every year, others tailor their coverage based on where they are on the competitive spectrum, with rebuilding clubs more likely to have scouts here than ones who, if they make a trade, are hunting big leaguers instead of teenage lottery tickets. So while Martes has a chance to make a significant impact on an Astros club poised to compete for their division and, maybe, a World Series, the ripples through the industry created by his acquisition are arguably more significant. Okay, on to Martes as a prospect…

On October 24, 2015, the Pittsburgh Pirates acquired Trevor Williams from the Miami Marlins in exchange for Richard Mitchell. Sort of. As ESPN’s Jayson Stark reported shortly thereafter, Williams was actually compensation for the Marlins’ hiring of pitching guru Jim Benedict. Mitchell was considered a non-prospect, while Williams was a former second-round pick, and is now working out of the Pittsburgh pen.

Last week, I asked Williams about the veracity of the report. Was he truly traded for a pitching instructor?

“It was weird,” said the 25-year-old right-hander.“On paper, I wasn’t, but in actuality, I was. It does make for a good story, because not many people get traded for a non-player. It is what it is. Whether you’re traded for a player, a front office guy, or a clubbie, you’re changing teams, you’re changing scenery.”

Williams wasn’t immediately aware of what had gone down. All he was told is that he was traded for “a minor leaguer.” Once the name became known, he went to his computer. Read the rest of this entry »

Real 2017 games have been played in earnest, but sample sizes are so small that we might as well continue our look at 2016 starting-pitcher contact management by pitch type. Last time, we reviewed the AL ERA qualifiers; today, it’s the NL qualifiers’ turn.

With the switch from the standard PITCHf/x pitch-tracking system to Trackman, a few missteps are to be expected. Dave Cameron, for example, recently pointed out that we have to be careful about reporting velocity right now. Jeff Zimmerman gave us a way to convert old velocities into today’s reality, and Tom Tango offered up way to use current readings to approximate velocities as they were calculated by the previous methodology. For those interested in the simplest possible method, it appears as though subtracting three-quarters of a mile per hour from a pitcher’s reported velocity arrives at roughly the same figure as the previous system would have produced.

But that doesn’t account for the situation in its entirety. If we look at what Brandon Finnegan did in his first (excellent) start, we’ll notice that the movement numbers are also a little off right now. It’s enough to want to throw your hands up and just emote, as I did on the latest episode of our Sleeper and The Bust podcast.

It’s okay to express frustration. It’s cathartic and release is good. Breathe deeply through the nose.

But we also need to pick ourselves up and dust ourselves off. Finnegan did not, as the leaderboards suggest, just record the ninth-most ride on a fastball that we’ve witnessed over the last 15 years. That’s not what was so impressive about the movement and velocities of his pitches in his 2017 debut. But discovering what was impressive can help us better navigate the suddenly unsteady waters of pitcher analysis.

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.
