In the bottom of the sixth inning with the Cardinals trailing 2-1, St. Louis pitcher Seth Maness gave up singles to Anthony Gose and Jose Reyes. Melky Cabrera followed by reaching on a fielding error by third baseman Matt Carpenter, loading the bases for slugger Jose Bautista. On the third pitch of the at-bat, Bautista pounced on an 89 mph sinker, but he lined it right to second baseman Daniel Descalso, who caught the ball, then flipped to shortstop Jhonny Peralta to double Reyes. Peralta then threw over to Allen Craig to complete the trifecta.
Blue Jays manager John Gibbons came out of the dugout to complain that second base umpire Manny Gonzalez, who hit the deck to avoid being drilled by Bautista's shot, didn't signal the ball had been caught. However, since infield traps wouldn't be subject to review anyway, the play stood.
The triple play was the first pulled off by the Cardinals since May 5, 2005, when the Padres' Ramon Hernandez hit into one against Matt Morris; Albert Pujols and David Eckstein made the outs. It was the first time the Blue Jays hit into a triple play since May 12, 2008, when Lyle Overbay hit into an unassisted one pulled off by the Indians' Asdrubal Cabrera, with Cliff Lee pitching.
The Yankees pulled off the season's first triple play back on April 17 against the Rays, while the Rockies pulled off the second on May 18 against the Padres, an interference-aided one at that. Updating the count by the Society for American Baseball Research, there have now been 694 triple plays dating back to 1876.
