June 30, 1998 With an eighth-inning homer against the Arizona Diamondbacks, Chicago Cubs’ slugger Sammy Sosa extends his major league record for home runs in a month, hitting his 20th round-tripper in June. At the start of July, the Chicago outfielder’s season total is 31, four less than Mark McGwire the St Louis Cardinal infielder he is battling on a daily basis, who also homered today.
