I'm going to venture to say that this picture was taken on April 4th, 1998. The Orioles were hosting the Tigers in a Saturday afternoon game. I'm going to guess by the angle of the sun and Alomar's long sleeves indicating the early season game. (Game time temperature was 50 degrees and sunny that day). The orange stripe on the leg of the sliding player tell me it's Tigers outfielder Brian Hunter. He swiped 3 bases on Chris Hoiles that day in a 2 to 1 losing effort. Even though he stole a base the next day (Sunday the 5th) Alomar didn't play that day until the 8th inning. Even then there were no stolen base attempts by the Tigers in the 9th inning.
Thanks for the cards Scott and thanks for helping me me play "When was it?"!
