From today’s installment of the BR Bullpen on Baseball-Reference.com:
Dalton Jones of the Tigers loses a grand slam against the Red Sox when he passes teammate Don Wert on the basepaths. Jones pinch hits for Jim Price and belts a 2-2 pitch from Vicente Romo into the right field upper deck for an apparent grand slam. However, he passes Wert between first and second and is called out, ending up with a three-RBI single.
Here’s the boxscore from that game, a 3-2 Red Sox win.
