So, to the best of my ability I tried to crank out a list although I really just did a lot of data entry myself. To get credit as a "former Giant", you had to have played at least one game for the Giants (L.A. or New York variety) and then played for the Dodgers. If you had a career path that took you from Dodgers to Giants to Dodgers (such as Dave Anderson or Orel Hershiser), you are only a former Giant on your second tour of duty with the Dodgers.

In 2005, the Dodgers sported four former Giants on their roster: Wilson Alvarez, Jose Cruz Jr., Jeff Kent and Ricky Ledee. That was the first time the Dodgers had four former Giants on the squad since 1986 when the Dodgers had the heroic quartet of Enos Cabell, Bill Madlock, Alex Treviño, and Terry Whitfield.

In 1943, the Dodgers had five former Giants, mostly all scrubs as World War II made teams desperate to pick up just about any player they could find. Those five were: Freddie Fitzsimmons, Alex Kampouris, Bill Lohrman, Joe Orengo, and Bill Sayles. It's likely that all five weren't on the roster at the same time.

But the record year for former Giants on the Dodgers is 1932 when there were six. That included two future Hall of Famers: George Kelly and Hack Wilson. The other four were Ike Boone, Lefty O'Doul, Fay Thomas and Fresco Thompson. Thompson would serve as the Dodgers general manager in 1968.

The first player to make the list was Dave Orr in 1888. Orr had played one game for the Giants in 1883. There would not be another ex-Giant on the Dodgers until Monte Ward played for Brooklyn in 1891-92.

Of the six years the Dodgers won the World Series, there were only two seasons that the Dodgers had an ex-Giant on the roster: 1963 (Daryl Spencer) and 1981 (Derrel Thomas).

For the most part most of the ex-Giants who have gone on to play for the Dodgers have been bench players, but there have been a few stars. Hall of Famers who have done it are: Monte Ward, Willie Keeler, Rube Marquard, Dave Bancroft, George Kelly, Freddie Lindstrom, Hack Wilson, Joe Medwick, Hoyt Wilhelm, Juan Marichal, and Gary Carter.

The longest tenure with the Dodgers of any ex-Giant is Manny Mota. Mota played with the Giants in 1962 and played for the Dodgers from 1969 through 1980 and also briefly in 1982. Fitzsimmons's seven seasons in Brooklyn is the leader in that incarnation of the team.

From the time of Jackie Robinson's debut in 1947 until the advent of divisional play in 1969, the Dodgers employed only five ex-Giants: Mickey Livingston (2 games in 1951), Sal Maglie (crucial pickup for the Dodgers in 1956), Daryl Spencer, Dick Schofield (1966-67) and Len Gabrielson.

Now, if I were a thorough person I would make the list going the other way: ex-Dodgers who went on to play for the Giants. But I'm not that thorough.

Update - Some links fixed and Len Gabrielson added to list of ex-Giants on the Dodgers between 1947 and 1969.

Update 2 - "Fixing" being a relative term. Corrections are welcome.

Update 3 - I had left out Freddie Lindstrom from the list of Hall of Famers who were ex-Giants who went on to play for the Dodgers. But, c'mon, it's Freddie Lindstrom!
