The Rockies and Pirates combined for five sacrifice flies, tying the major league record, in Colorado's 10-8 win over Pittsburgh at PNC Park. Matt Holliday had two for Colorado as did well as one for the Rockies center fielder (see the boxscore for his name). Adam La Roche and Xavier Nady had Pittsburgh's sacrifice flies.
Five sacrifice flies in a game happens quite a bit. In fact the last game with five sacrifice flies happened on July 3 when Kansas City routed Seattle 17-3.
The Rockies and Pirates "combined" for five sacrifice flies in a game last year on June 7, 2006. Except Colorado had all five. Seattle also had five sacrifice flies in a game on August 7, 1988 against Oakland.
