[7] Six of those were hit by Don Mattingly, who set a record for most grand slam home runs in one season with six.
In addition, Mattingly had tied Dale Long's major league record by hitting home runs in eight consecutive games (record later tied again by Ken Griffey Jr., of Seattle in 1993), as well as stroking an extra base hit in ten consecutive games.
In June 1987, it was reported that Mattingly injured his back during some clubhouse horseplay with pitcher Bob Shirley though both denied this.
On July 13, 1987, George Steinbrenner told manager Lou Piniella that the acquisition of Steve Trout would win the Yankees the pennant.
