Apparently due in part to the late announcement of the series -- promoters had only a month to sell tickets as compared to 3 months last year -- the two-game exhibition series had 11,000 fewer attendees this year for the Astros and Marlins than for last year's Dodgers-Mets series.

But today's game brought back some, uh, fond(?) memories...

Then the 11,270 in attendance showered the field with paper cups and debris after the game was called after nine innings, tied 2-2. The managers had a made a pregame decision that with the personnel the two teams had on hand, the game would not go into extra innings under any circumstances.

\"Major League Baseball regrets that the fans of Mexico City were disappointed the second game of Serie de Primavera ended in a 2-2 tie and was unable to extend into extra innings,\" MLB said in statement released after the game. \"As is the case in many Spring Training games, it was decided prior to the start that the game would be limited to nine innings only. Overall, both clubs had a great two days of competitive baseball and the players really enjoyed the Mexico City crowds.\"
