Author’s note: I originally planned this article in two parts, the first of which was published earlier in the week. I’ve since decided it works better combined into a single article, so here it is all in once place. – J.A.S.
In the nearly 120 years of the great Dodger-Giant rivalry, more than 200 players have suited up for both sides, either as a player or manager, including 22 Hall of Famers. For most of these men it is an easy undertaking to find cards of them as Dodgers and as Giants.
Most often their Dodger and Giant cards come from different years or different sets, as in the case of the two Frank Robinson cards pictured, eleven years apart. However, it is sometimes possible to find these Dodger-Giant pairings within a single set.
When this happens, the player (or manager) achieves true “double agent” status, turns from hero to villain (or vice versa) among the team faithful, earns the double-takes of many a collector, and most importantly attains immortality with a spot in this article.
In the sections that follow, I will present a chronological list of the nearly two dozen Dodger-Giant double agents I could track down in my research. Please let me know in the comments if I missed anyone.
1903-04

On December 12, 1903, the Brooklyn Superbas sent Bill Dahlen to New York for Charlie Babb and Jack Cronin. As a result, Dahlen can be found with both squads in the 1903-04 Breisch-Williams (E107) set and has the honor of being the first ever Dodger-Giant double agent.

1914-15
Here is one that really doesn’t count but is interesting enough to include nonetheless. On August 31, 1915, the Brooklyn Robins claimed Hall of Fame hurler Rube Marquard off waivers following his release by the Giants. Look close, however, and you’ll see Marquard’s 1915 card puts him with the other Brooklyn team, the Tip Tops of the Federal League!
I originally thought the fine folks at Cracker Jack had simply erred until Ralph Carhart helped explain things.

As Ralph noted, Rube’s “Tip Top flip flop” may offer us a clue to the Cracker Jack production calendar. I’ll further offer that the NYG still on Marquard’s uniform could signal that “the drama was playing out” after it was too late to change art but not too late to change type.
1933
On June 16, 1933, the Giants traded Sam Leslie to the Dodgers for Watty Clark and Lefty O’Doul. Clark had only a single 1933 Goudey card, which depicted him as a Dodger, while Leslie had no 1933 cards at all. O’Doul, on the other hand, had two cards in the Goudey set: one as a Dodger and one as a Giant.
The first card came early in the year as part of the set’s third sheet while his second card, along with those of numerous other Giants and Senators, was something of a bonus card as part of the set’s World Series (sheet 10) release.
1948
In July 1948 Brooklyn general manager Branch Rickey and New York owner Horace Stoneham came to an agreement that allowed Brooklyn manager Leo Durocher to take over the Giants. The 1948 R346 “Blue Tint” set noted the update and may well have inspired future Topps airbrushers with its treatment of Durocher’s cap.

1982
A part of my childhood was destroyed when Reggie Smith left the Dodgers and signed as a free agent with San Francisco on February 27, 1982. A giant (okay, pun intended) setback in my grieving process came when Topps pushed out its Traded set for the year and documented the move in cardboard. But alas, at least we still had Dusty!
As a side note, the Traded card presents an interesting blend of numbers for the man who formerly wore #8 with the Dodgers and would wear #14 with the Giants. His jersey shows him as #60 while his bat has a 30 on it, which I take to mean it belonged to teammate Chili Davis.
1984
No-o-o-o-o-o-o-o! They got Dusty too?! Sadly it was no April Fools joke when the Giants signed fan favorite Dusty Baker as a free agent on April 1, 1984, and this two Traded/Update sets were there to ratify the trauma.
1985
A rare trade between the Dodgers and Giants on December 11, 1985 produced two more double agents. The first was fan favorite Candy Maldonado, who like Baker before him made both the Topps and Fleer sets.
And on the back end of that same trade…
Oddly, neither Trevino nor Maldonado cracked the 660-card 1986 Donruss checklist despite the set including 21 different Giants and 24 different Dodgers. In Trevino’s case, he was San Francisco’s primary back-up catcher behind Bob Brenley played in 57 games. As for Maldonado, he played in 123 games, leading all reserve players and ranking eighth overall on the team.
1991
Fast forward to 1991 and the number of baseball card sets had reached absurd levels. Therefore, it should be no surprise that when free agent superstar Gary Carter signed with the Dodgers on March 26, 1991, he would set new records for cardboard double agency.
First here’s Topps.
Next up are the Kid’s two Fleer cards. Warning: Sunglasses may be required.
Upper Deck was of course also in the act by now.
And finally, Score put out two Carter cards as well, ridiculously similar to each other to the point of almost seeming impossible.
A similar octet of cards belonged to Brett Butler this same year, with Bugsy landing in Los Angeles via free agency on December 14, 1990.

1992
Dave Anderson signed with the Dodgers as a free agent on January 28, 1992, but this time only one company, Score, seemed to take notice.
1993
It was Fleer and only Fleer on the job when Todd Benzinger headed north to San Francisco as a free agent on January 13, 1993.
Meanwhile, Cory Snyder got three times the cardboard love when he took his talents to L.A. on December 5, 1992. Score Select was particularly ambitious, dropping Snyder out of an airplane for their photo shoot.

1994
On June 19, 1994, following his release from the Dodgers, the Giants signed Darryl Strawberry to a cup of coffee. Little used by both teams in 1994, Darryl hit double agent status with only a single cardmaker, Fleer.
1998
On December 8, 1997, infielder Jose Vizcaino signed with the Dodgers as a free agent after playing the regular season with the Giants. However, the baseball card production process was by this time so fast that nearly all of Vizcaino’s base cards already had him as a Dodger. As a result, his double agency was limited to the 1998 Fleer Tradition set only.
2000
On January 11, 2000, F.P. Santangelo signed with the Dodgers as a free agent. While very few companies even had a single card of the oft abbreviated Frank-Paul, Upper Deck came through with cards on both sides of the cardboard rivalry.
2003
The Giants signed Gold Glove centerfielder Marquis Grissom as a free agency on December 7, 2002, leading to a pair of Fleer Tradition cards based on Fleer’s sharp 1963 design.
Curiously, the Fleer Tradition Update cards (not just Grissom’s) omitted the city from team names. If there’s any story to it, let me know in the comments.
2006
On January 3, 2006, pitcher Brett Tomko signed a free agent deal with the Dodgers. If nothing else, the move gave Topps a chance to show off how far they’d come since their drunken airbrush days. Scary good if you ask me.
Tomko’s Dodger card above came from a Dodger-specific team set, but he also earned a card in the Topps Updates and Highlights set for good measure.

2007
When the Dodgers signed all-star right-hander Jason Schmidt on December 6, 2006, no two companies went the same route. First up, Fleer simply turned back the clock to the days of 1981 Donruss.

Meanwhile Topps ventured back to 1983 and the Fleer Joel Youngblood card or Eddie Murphy movie with this special insert…

…while also going full Tomko across their Pepsi and Opening Day releases.
Upper Deck came through with a nice pair of landscape Schmidt cards, though neither is a true Giants card since both go with Dodgers in the header.
Would I be remiss if I didn’t report that the first of the two Schmidt cards is also available in Gold, Predictor Green, and First Edition? Take your pick I guess!
2009
Brad Penny signed as a free agent with the Giants on August 31, 2009, following half a season with the Red Sox and a longer stint before that with L.A. This landed Penny cards on three teams in 2009, including double agent status with Topps Heritage.
2013
The final player (as of 2019) with a Dodger and Giant card from the same set is Brian Wilson, who signed as a free agent with the Dodgers mid-season on July 30, 2013. Lucky for you, Topps was there to document the before and after in pretty much every possible color!
analysis
On one hand, Dodger-Giant double agents reflect an oddball phenomenon of at best passing interest to fans of either of the two teams. However, their distinctly non-random occurrences over the years also point to important changes in the game and the hobby.

Just looking at the graph, it is possible to see all of the following:
- Prevalence of multi-year issues in the early days of the hobby
- Increased player movement with the advent of free agency
- Introduction of Traded/Update sets
- Increase in the number of companies issuing sets (1981-2008)
- Reduction in the number of companies issuing sets (2009-present)
I will leave it to others to identify the cardboard double-agents of baseball’s other great rivalries (e.g., Yankees-Red Sox), but I’ll hazard a guess already that a graph of the data would look very much like mine.
Cool post Jason. Off topic slightly. Just saw a Lefty O’Doul autographed ball with San Francisco Seals at Cape Cod card store. Had about 25 autos on it. From the 40’s

Technically I think the 2007 Fleer Jason Schmidt is also an Upper Deck product. If you look on the back you’ll see UDC in the legal information, with the same address in North Las Vegas. At least the insert cards I see online have that on the back.

Good point. Things get a bit dizzying after about 1990 when Topps started putting out Bowman cards.

Thank you! If I had the skills I would have liked to recolor Spidey’s uniforms to Dodger and Giant colors, but I gave up after some really bad efforts.

So the Penny situation where he lands on 3 different teams in one year is one which we’ve needed to cover in a post here since it doesn’t happen often (not going to count online releases). We’ve had some discussion on twitter but not enough to put together a complete checklist.

My method here was to begin with a full list of everyone who played for Dodger and Giant franchises, narrow it down to guys who played on both teams in same or consecutive years, and then search all cards for the relevant year(s). Managers and the 1947-66 Exhibits set were separate checks.
For this three-team list I suppose you’d need to find a way to get a list of all players who played for at least three teams in 2 years. Some serious Excel skills would help a lot.

Thank you for another outstanding, scholarly, and entertaining piece of cardboard gold! As a southern California native, those player names and cards bring back some wonderful memories. The Giants were always and continue to be baseball enemy number one!
