KATOH Trade-Deadline Roundup: Prospects and Teams

In the table below, you’ll find a treasure trove of information pertaining to the prospect-y players who changed hands this trade deadline. There were 47 of them in all. The “KATOH” and “KATOH+” columns refer to each player’s projected WAR forecast for the first six years of his major-league career, as evaluated by my newly updated KATOH systemKATOH denotes WAR forecast for first six years of player’s major-league career. KATOH+ uses similar methodology with consideration also for Baseball America’s rankings. The right-most column refers to lead prospect analyst Eric Longenhagen’s scouting grades, which should serve as something of a sanity check for my admittedly flawed projections.

Below the upcoming massive table, one can find a KATOH-generated, team-level analysis of the prospect value that changed hands at the trade deadline, followed by a chart comparing my KATOH numbers with Longenhagen’s scouting grades.

Using cutting-edge technology know as “pivot tables,” I aggregated these KATOH+ projections both by acquiring team and trading team. Then I took the difference to make the following chart.


Here’s the data behind it.

By my math, the team whose farm system benefited most from this year’s deadline isn’t the New York Yankees, but the Milwaukee Brewers. With a KATOH+ forecast of 9.9 WAR, stud center fielder Lewis Brinson accounts for most of the team’s acquired value, but Phil Bickford (5.1 WAR), Andrew Susac (2.5 WAR) and Luis Ortiz (2.1 WAR) also help out their cause. The Brewers have a history of trading for KATOH darlings, and this year’s trade deadline is no different.

The Yankees also rank highly, as they turned Aroldis Chapman, Andrew Miller and Carlos Beltran into several prospects. Gleyber Torres (7.1 WAR), Clint Frazier (4.7 WAR) and Justus Sheffield (2.4 WAR) are the headliners, while seven other minor leaguers combine for 5.1 WAR. Among those seven is Dillon Tate, whose tools suggest he’s much better than his 0.2 WAR KATOH forecast. The value they added is slightly offset by the departure of Vincente Campos (1.4 WAR) in exchange for Tyler Clippard.

Unsurprisingly, the biggest losers in terms of prospect value include the Cubs, Rangers, Giants and Indians. The Rangers top the list, mostly because they paid a pretty penny — Brinson and Ortiz — for Jonathan Lucroy. The Cubs are a close second, as they gave up a lot of potential future value to add Aroldis Chapman, Mike Montgomery and Joe Smith to their bullpen. Somewhat surprisingly, KATOH isn’t particularly fond of the three pitching prospects the Dodgers coughed up for Rich Hill and Josh Reddick. Although they each received a 50 FV from Longenhagen, KATOH projects each of Grant Holmes, Jharel Cotton and Frankie Montas for 2-3 WAR. Going by the numbers, they’re only mildly interesting prospects.

Just for kicks, I also plotted Eric Longenhagen’s FV rankings versus my KATOH forecasts for each player traded. Eric’s rankings and my projections are generally in agreement, but there are a few instances where the projections and the scouting don’t quite line up.

I look forward to the Brewers being a good team again, though I do wonder if Ryan Braun is still good by the time they get there.
