Trading An Ace In The Offseason Can Pay Dividends
Back in 2016, we examined the history of teams trading an ace at the trade deadline and during the offseason.
In short, teams that trade a frontline pitcher for a prospect-laden package at the trade deadline almost never receive equal value in return, while teams that wait until the offseason fare better.
On the heels of the Rays trading Blake Snell and the Cubs trading Yu Darvish to the Padres, it’s instructive to look at precedent once more. We’ve updated our findings through the end of the 2020 season to provide a clearer picture of how likely it is the players the Rays and Cubs acquired will actually outperform Snell and Darvish over the rest of their careers.
As in our previous stories, we examined every offseason trade in the wild-card era (1995 to present) involving an ace-caliber pitcher and measured the post-trade career wins above replacement (WAR) totals, as calculated by Baseball-Reference.com, of the players involved.
Because of the different dynamics between trading a player during the regular season and the offseason, only trades made in the offseason were considered.
Our baseline criteria is three-fold. The deal must involve a pitcher who:
(1) Finished in the top three in Cy Young Award voting within the previous three seasons
(2) Was the primary player in the trade
(3) Was traded for at least two players who had not yet exhausted prospect eligibility.
(The Roger Clemens trade before the 1999 season and the Mike Hampton trade after the 1999 season are not included because Clemens and Hampton were primarily traded for major leaguers. The trade of Dontrelle Willis in 2007 is not included because Miguel Cabrera was the primary player in the trade.)
Please note Baseball-Reference adjusts its WAR calculations every few years, so career WAR totals for some players may have changed between 2016 and 2020 even if they were no longer playing.

In seven of the 13 instances an “ace” was traded for a prospect-laden package during the offseason in the wild-card era, the players received ended up producing more career WAR after the trade than the frontline pitcher who was traded.
The balance could shift further in the coming years. The Chris Sale trade between the Red Sox and White Sox still has many years to play out, and Moncada and Kopech may eventually swing the trade in favor of the White Sox. It is notable, though, that it’s been four seasons since the trade and the Red Sox still have the edge even with Sale missing the entire 2020 season after having Tommy John surgery—an indication of just how long it can take before the trade of an ace reaches a break-even point.
Of note, it is critical for the team trading the ace to actually keep the players that help them “win” the deal over time. The Twins (with Carlos Gomez in the Santana trade) and Diamondbacks (with Jorge De La Rosa in the Schilling trade and veteran Javier Vazquez in the Johnson trade) notably failed to do so, making the deals worse for them in retrospect.
Trading Snell and Darvish undeniably sets the Rays and Cubs back for 2021. If history is any indication, the teams can at least retain some legitimate hope that the players they received will tilt the trades in their favor over time.
