On June 9, 1998 — In the third inning of the Angels’ 10-8 win over the Diamondbacks, Anaheim’s Cecil Fielder and Arizona’s Yamil Benitez both hit a grand slam in the Bank One Ballpark contest. It is the first time both teams hit bases-full home runs in the same inning since 1992, when Cubs infielder Ryne Sandberg and Pirates slugger Jeff King also accomplished the feat, playing at Three Rivers Stadium.
