Over the years, a good deal of effort has been put into determining the value of prospects. Victor Wang, Scott McKinney (updated here), Kevin Creagh and Steve DiMiceli together, and Jeff Zimmerman have all published work on the subject, roughly in that order.

The reasoning behind such efforts is fairly obvious: teams trade prospects for proven players all the time. Finding an objective way to evaluate those trades is useful to better understanding how the sport operates. Indeed, FanGraphs has benefited from those prospect-valuation studies on multiple occasions.

With another year having passed, I’ve attempted to build on the work of others and produce updated valuations of my own. Previous efforts have been very helpful in the process, while the input of prospect analysts Eric Longenhagen and Kiley McDaniel has helped me find results that would be most useful.

In building this study, I set out with the following aims:

• To separate players into as many useful tiers as possible without creating unnecessary distinctions.
• To use as much data as possible so long as it was useful and likely still relevant today.
• To make the valuations as forward-looking as possible.
• To recognize that player development is not linear and that players appearing on prospect lists vary from major-league-ready to raw, Rookie-level talents.

To those various ends, here are some of the parameters of this study:

1. Baseball America’s top-100 lists from 1996 to 2010 serve as the foundation for prospect grades.
When I started the study, I looked at the lists dating back to 1990, separating out position players from pitchers and organizing by year. I found that the evaluations from the earlier part of the 90s — especially those for pitchers — had considerably worse outcomes than those that came after. I debated whether or not to throw out the data. Eventually, though, I decided that since 15 years of prospect numbers were showing decidedly different results, and that there was considerable turmoil occurring within the sport during that time — expansion, a strike, and a lockout — it seemed reasonable to toss the earlier years and go with the assumption that the 1996-2010 lists more accurately represented prospect evaluation today and going forward than the rankings of 25 years ago.

Does Shohei Ohtani’s success portend more two-way players in MLB? Opinions vary, albeit with the bears clearly outnumbering the bulls — at least in terms of expected production. While a certain amount of copy-catting seems inevitable, the presumptive American League rookie of the year paired a .925 OPS with a 3.31 ERA and a 10.95 strikeout rate. He was dominant on both sides of the ball in a way that’s unlikely to be replicated by anyone other than himself.

A pair of former two-way players I spoke to this season are among the skeptics. Which isn’t to say they hate the idea. Nor do they feel the Brendan McKays of the world don’t deserve every opportunity to show they can follow in Ohtani’s footsteps (hopefully without elbow surgery being part of the equation).

Steven Brault created a bit of a buzz by going his first 33 big-league plate appearances without striking out. On the heels of that eye-opening accomplishment, I asked the Pittsburgh Pirates left-hander for his opinion on why a player should, and shouldn’t, be able to play both ways at the highest level.

“The reason you should is that you’re good enough,” responded Brault, who’d excelled as a two-way player at Division II Regis University. “If you’re a good enough hitter, and a good enough pitcher, it stands to reason that your team would want you to do both. The reason you shouldn’t is that you can’t play every day. That’s been the case with Ohtani. On the days he pitched he didn’t hit, and on the day before he didn’t hit. Same for the day after. They had to make sure his body was ready to pitch. Read the rest of this entry »

Ben Lindbergh and Jeff Sullivan banter about a Carter Capps-like cricket bowler, another Scott Boras nautical analogy, the latest Mariners-Rays trade (this time involving Mike Zunino, Guillermo Heredia, and Mallex Smith), how fans felt about the 2018 season, and a Twitter kerfuffle caused by comments made by Bill James, then (31:19) bring on former major leaguer F.P. Santangelo to discuss the ins and outs of sign-stealing and pitch-tipping, peeking at the catcher, headsets on the field, playing with Barry Bonds, his memories of the Expos and thoughts on Montreal as a baseball city, playing several positions, getting hit by a high number of pitches, career longevity, and more.

This post is part of a series concerning the 2019 Today’s Game Era Committee ballot, covering executives, managers and long-retired players whose candidacies will be voted upon at the Winter Meetings in Las Vegas on December 9. Use the tool above to read the introduction and other installments. For an introduction to JAWS, see here. Several profiles in this series are adapted from work previously published at SI.com and Baseball Prospectus. All WAR figures refer to the Baseball-Reference version unless otherwise indicated.

Kirk Gibson’s walkoff home run off Dennis Eckersley may be the year’s most enduring highlight, but Orel Hershiser owned 1988 the way Babe Ruth owned 1927, or Roger Maris 1961, or Denny McLain 1968. That year, the Dodgers’ wiry righty set a still-standing record with 59 consecutive scoreless innings, surpassing that of Don Drysdale. After his 23 wins, 15 complete games, eight shutouts, 267 innings, and 7.2 WAR all led the NL, he won MVP honors in both the NLCS and World Series while helping a banged-up Dodgers squad upset the heavily favored Mets and A’s. Not only was he the unanimous winner of the NL Cy Young Award, he netted the year’s Sports Illustrated Sportsman of the Year and Associated Press Male Athlete of the Year awards, as well. It was a very good year.

Hershiser never equaled those heights again, but who could? Still, he showed incredible tenacity in an 18-year major-league career (1983-2000) bifurcated by a 1990 shoulder injury, ranking as the NL’s most valuable pitcher for a six-year stretch (1984-89) before his injury and reinventing himself after a groundbreaking surgery by Dr. Frank Jobe, best known for his innovation in saving Tommy John’s career. Hershiser actually won more games and pitched in more World Series after the injury than before (105 and two, compared to 99 and one), living up to the nickname “The Bulldog,” which manager Tommy Lasorda had originally bestowed upon him as a rookie to inspire him to pitch more aggressively.

Drafted by the Dodgers in the 17th round out of Bowling Green in 1979, Hershiser made his major \[league debut on September 1, 1983. After pitching eight games in relief that year and spending most of the first three months of the 1984 season in the bullpen, he tossed a complete game against the Cubs on June 29, allowing one run and setting off a 33.2-inning scoreless streak that included three complete-game shutouts, two of them two-hit, nine-strikeout efforts. He finished third in the league with a 2.66 ERA in 189.2 innings, and came in third in the NL Rookie of the Year vote behind Dwight Gooden and Juan Samuel. Armed with a new split-fingered fastball to complement a sinker that would become legendary, he made even bigger waves by going 19-3 with a 2.03 ERA (again third in the league) and finishing third in the Cy Young vote (Gooden won that, too).

It’s time to do this all again. A few days ago, I ran an annual polling project, asking how you felt about the season that was, on a team-by-team basis. It might seem like a silly question, or it might seem like the results would be obvious, but tradition is tradition, and I always get a kick out of the data analysis. This is the data-analysis post. I suppose I’m under no obligation to share the results with the voting public, and I could just keep all the numbers to myself, but then I don’t know what the point of any of this would be. I already struggle enough to understand what the point of any of this is. Don’t need to make the problem worse.

To refresh your memories, that polling project included 30 polls, with one for each club. Here is an example of what the polls looked like:

I decided while working on the Top 50 Free Agents post that it would make sense to also write up the top trade target on the market. Since new Mets GM Brodie Van Wagenen said the team plans to compete in 2019, it seems like Jacob deGrom and Noah Syndergaard are unlikely to be dealt — or, at least not during the offseason. That points to J.T. Realmuto as the clear top trade target in the league (and No. 24 in July’s Trade Value Rankings) — and that’s before nearly half the questions in my chat on Wednesday were asking me how much it would cost for various teams to trade for Realmuto.

I could approach this from an insider-y perspective and tell you what teams are telling me the price probably is, but that approach is limited in a few ways. First off, I’m not sure anyone really knows what the price is: the Marlins have turned down strong offers for a year now and still seem inclined to try to extend Realmuto, even thoughhis agent said he’s not having it. Since Miami has this one major asset left to move in its rebuild, they may act irrationally, but the market pieces may be falling into place for someone to pay a price that justified this delay.

If forced to succinctly describe the current state of catching in the major leagues, I would say it sucks. I’ll let Mike Petriello to provide some details and point you to the positional leaderboard, but if you just tried to predict which catchers would be worth two-plus wins and remain at catcher primarily for the next five seasons, how many would you have? Realmuto is one, and if you think Willson Contreras and Gary Sanchez may play a lot more first base or get hurt or be inconsistent in this span, it’s possible that there isn’t another one. Being charitable, there’s just a handful, and they all cost a lot or aren’t available.

Putting all of this together, Realmuto offers the age-28 and age-29 seasons of the best long- and short-term catcher in the game, and he’ll cost between $15 million and $20 million for those seasons, depending on how his arbitration salaries work out. You have him long enough to make two runs at a title and get a comp pick at the end, an exclusive negotiating window for an extension, a non-risky length of a deal, and cheap enough salaries that any team can afford it.
