Who have been the best players in the Midwest League so far this season? I recently posed that question to some of the circuit’s broadcasters, with an important qualifier: I requested that they base their selections on what they’ve seen with their own eyes, and not on players’ reputations. I also asked for snapshot observations on each player named, which the respondents graciously took the time to provide.

As noted in last season’s survey, the Midwest League comprises two divisions, with an unbalanced schedule. Couple that with the fact that this is a midseason look, and the respondents will have seen some players more than others (or not at all). For that reason, notable prospects may not appear on a particular list.

Six broadcasters participated — four from the Eastern Division and two from the Western Division. Their respective lists were put together within the past couple of weeks.

1. Wander Franco: A generational talent. Hitting and fielding. Sadly we only got to see him for one series with the Midwest League crossover schedules, but you could tell he was special, with baseball instincts and natural ability. Hits the ball hard and has everything you could want. Will be fun to watch him go up the ladder.

2. Alek Thomas: This kid has crushed us all season. Had a series in early July where he was 9-for-10 and very nearly had cycles on back-to-back days. Hit the ball all over Dozer Park with power, using all fields and [showing] his speed. No matter what was tried, we couldn’t get him out that series. Read the rest of this entry »

Recently, I’ve been pondering the strange way I think about HR/FB ratio. On one hand, it’s a way to explain away a hot or cold stretch from a hitter. When Joc Pederson got off to a blazing start this year, I looked at his HR/FB, a spicy 33.3% through the end of April, and told myself it was a small sample size phenomena. That’s the first way I use HR/FB for hitters — as a sanity check.

At the same time, HR/FB is something we’ve all used to explain someone’s power. Joey Gallo is powerful, obviously. How do we know that? Well, he hits the ball really hard, which gets expressed by more of his fly balls turning into home runs. Gallo had a 47.6% HR/FB at the end of April, and even though I didn’t expect that to continue, I was willing to accept high numbers for Gallo’s HR/FB much more easily than I was for Pederson.

This leaves HR/FB in a weird spot. It’s a number we use to see if players are getting lucky or unlucky relative to average, but it’s also a number we use to look for underlying skill. Problems arise when it’s unclear what is noise and what is signal. Is David Fletcher unlucky to have a 5.4% HR/FB? Surely not — he’s a contact hitter. Is Jose Ramirez unlucky to have a 6.5% HR/FB? I assume so, but I only assume so because he hit 39 home runs with a 16.9% HR/FB last year. What if last year was the outlier, not this one?

Another way to think about this conundrum is that HR/FB contains an inherent contradiction we have to work around mentally. Putting fly balls as the bottom of the ratio implies that all fly balls are created equal, and that’s clearly untrue. Gallo is unloading on the ball, crushing many of the fly balls he hits into orbit. Fletcher, meanwhile, sports one of the lowest average exit velocities in the game. Even though a home run counts the same for each, the population of fly balls is tremendously different. How do we handle this contradiction? Read the rest of this entry »

After a surprise first-place finish in the National League East last year, the Atlanta Braves entered this offseason searching for an offensive threat to bolster their lineup. After being shutout twice in their Division Series matchup against the Dodgers, they probably had good reason to be on the lookout for a new bat to add to their roster. They quickly struck a one-year deal with Josh Donaldson worth $23 million in the hopes that he would rekindle some of the magic that made him the second-most valuable player in baseball from 2013-2017.

Through the first two months of the season, it seemed like a worst-case scenario was playing out for the Braves’ biggest offseason acquisition. Through May 31, Donaldson had posted a 118 wRC+ and 1.2 WAR in 217 plate appearances. Above average, yes, but a far cry from his 148 wRC+ he averaged annually in the five years prior to 2018. With a lengthy injury history since at least 2016, you had to wonder if all that wear and tear had caught up with his 33-year-old body.

A shoulder injury sapped him of his power last year, so it was a little worrisome that his ISO was just .186 through the first two months of the season. That would have been his lowest power output since 2012, the year before he broke out with the Athletics. But more concerning was the 28.1% strikeout rate, higher than any other season in his career except for the brief cup of coffee he received way back in 2010. In his prime, he had always been able to combine reasonable strikeout rates with his massive power.

Since June 1, however, Donaldson has put together a vintage performance. He’s matched his previous offensive output exactly, posting a 148 wRC+ and 1.8 WAR across 198 plate appearances. He’s tied for the National League lead in home runs during this period with 16. That puts him on pace to launch more than 30 home runs for the fourth time in five years. So what happened to his power early this season and why has it come on so strong recently? Read the rest of this entry »

This is an unusually sunny era in which to write about player development. Seemingly every other month, someone new finds their power stroke, optimizes their curveball, or writes a best-selling book about how players are embracing technology to improve. I don’t know if any one player embodies the face of the movement, if only because so many people have jump-started their careers with a swing change or weighted ball program.

It’s easy to forget that these kind of career-altering breakthroughs are still somewhat uncommon. Ballplayers are constantly tinkering — a new grip or arm slot here, a different stance or hand position there — and the vast majority of those developments will never break a projection system. Sometimes, they’re just meant to get a struggling player back on track. In many other cases, guys make changes that give them an edge, albeit a fleeting one. These adjustments generally don’t make headlines, but under the microscope, they offer a fascinating window into the game.

Consider the case of Glenn Sparkman. Sparkman, a 27-year-old clinging to a job in Kansas City’s rotation, is the kind of guy who constantly needs to be at the top of his game to succeed. He’s a righty with slightly above average arm strength; his secondaries are competent but unremarkable. His stats are as bland as the previous sentence:

Traditionally, the outfield corners are home to heavy hitters. This year’s crop of right fielders has combined for a 110 wRC+, one point ahead of first basemen for the current major-league high as well as the highest mark at the position since 2011. The left fielders’ collective mark of 106 is the majors’ third-highest, one point ahead of that of third basemen, and the position’s second-best mark since 2011.

Even so, several contenders — which for this series I’ve defined as teams who are above .500 or have playoff odds of at least 10.0%, a definition that as of today currently covers 17 teams — are getting meager offensive production at one corner or another, by which I mean receiving less than 1.0 WAR at the spot, which makes them eligible for a place among the Replacement Level Killers. As the July 31 trade deadline approaches, they may want to do something about that, particularly since there’s no August waiver period during which they can tweak the roster. Having said that, I’m somewhat less focused on these teams’ eventual solutions, whether via trades or internal options, than I am in pointing out the problems.

Also, note that I’ve ruled out including the Angels among the left fielders, since the mid-June return of Justin Upton, who had been sidelined for nearly three months by turf toe, has already provided the team a substantial upgrade; even while slumping lately, he’s accounted for 0.3 of the team’s 0.6 WAR in 25 games, a 2.0 WAR pace over 162.

Jay Jaffe: Howdy folks, good afternoon and welcome to another edition of my Thursday chat. I’m still digesting my amazing weekend at the Hall of Fame inductions in Cooperstown and neck deep in Replacement Level Killers, the fifth installment of which — corner outfielders — should be up soon. Obviously, there are a lot of questions about the July 31 trade deadline, so let’s get to it.

12:04

Jay Jaffe: I think we’ll see a lot of deals in the coming days. This breakdown from last year, compiled by the great Eric Stephen of True Blue LA, is worth bearing in mind: — Last year: 4 trades during the All-Star break 1 trade on July 21 1 trade on July 22 1 trade on July 24 2 trade on July 25 Then the floodgates, 35 trades over the final 6 days (18 on July 31) — Thus I suspect we’ll start seeing a trickle of deals soon, and then a flood.

12:07

Jay Jaffe: I would imagine it’s a factor but one individualized to each team — he’s obviously not going to the Astros given the presence of Alex Bregman and Gerrit Cole, for example. I suspect that the execs of any teams who are serious about acquiring him are discreetly discussing his potential reception with a few clubhouse leaders for some added input. But talent still carries the day, and his is considerable, particularly in a market that’s stretched pretty thin and one in which some of the other top targets — Bumgarner, Syndergaard — might not be dealt after all.
