How many MLB players have been credited with stats for two different teams on the same day?

Question

I ask because Ken Griffey Jr. just played in a make up game for the White Sox, which was for a day that he played for the Reds before being traded. If he would have hit a homer in that make up game it would have changed his actual 600th.

Answer 1

I was actually at the game where Youngblood got his hit against the Phillies. That said, I remember when Jose Cardenal got traded from the Phillies to the Mets in between games of a double header between the 2 teams so he played for both teams during a double header.  

Answer 2

Griff isnt the only one on the sox, who gets credit for playing for 2 diff teams in the same day, Heracio Ramirez who pitched the 13th also pitched for the Mariners on the 28th of April and today for the sox, and yes it wouldve changed the actual 600th homer, he would hit it before the one in Florida.

Answer 3

Joel Youngblood got a single for the NY Mets back in the late 70's...He was traded and later that night got a single for the Montreal Expos.

Answer 4

On August 4, 1982 Joel Youngblood actually did it in the same day.  In the afternoon he played for the Mets in Chicago and went 1 for 2.  He found out he got traded so he flew to Philadelphia where his new team, the Expos were playing that evening.  He entered the game as a pinch hitter and got a hit.

So he got hits for two different teams on the same day and they were both off Hall of Fame pitchers (Fergie Jenkins and Steve Carlton).

Answer 5

Back in history when teams played intentional double-headers, it happened all the time. There were many players that got hits after being traded to the other team playing in a double-header.

Joel Youngblood was not the first player to get hits for two different teams the same day, but he was the first to accomplish that feat while playing in two different cities.
