Mike Piazza sets the major league record for home runs by a rookie catcher when he hits his 29th round-tripper, a first-inning two-run shot off San Diego’s Doug Brocail over the center field fence at Jack Murphy Stadium. The National League’s eventual Rookie of the Year, who will finish the season with 35, breaks the mark set by Matt Nokes, who was a freshman backstop for the Tigers in 1987.
