Trades that were 'kiss of death' for both players

[Brownieand45sfan]

We talked about "worst" trades where one player turned out fantastic and the other one faded quietly from the scene. But what about trades that - coincidentally or not - ushered in the end of the careers of both players? Who can think of some examples? One rule: the players must have been "starters" in at least the year before the trade was consummated. Extra points for people who had particularly strong years the year prior to the trade and for players who were under 35 at the time of the trade.

I'll begin:

Red Sox' Roman Mejias to the Colt 45s for Pete Runnels.

In 1962, Mejias bats .286 for Houston (leading HOU in virtually every batting category), hits 24 HRs and is on the NL Top 10 leaderboard for Power/Speed. Then tanks to .227 for the Sox in '63, is given only 101 ABs for the '64 season and is out of baseball.

In '62, Runnels wins his second batting batting title in three years (top 3 in 4 of the last 5) and then chokes to .253 for Houston in '63 with a paltry 23 RBI in 388 ABs, and despite the low AB-total manages to be third in the NL in GIDP. Pete was out of baseball by mid-May of 1964.

I found one... Steve Finley (although he was over 35) was traded for Edgardo Alfonzo in 2005. Alfonzo was out of baseball by 2006 and Finley was bouncing around until Colorado released him in early '07.

November 3, 1970: Philadelphia Phillies trade Curt Flood with a player to be named later to the Washington Senators for Greg Goossen, Jeff Terpko, and Gene Martin. The Philadelphia Phillies sent Jeff Terpko (April 10, 1971) to the Washington Senators to complete the trade.

In 1971, Curt Flood played 13 games for the Senators and batted .200, his last year in the majors.

Greg Goosen and Gene Martin never played a game for the Phillies and Jeff Terpko was basically traded for himself since he was the "player to be named later" in the trade.
