record wins over all 30 franchises that have existed since 1901. May May 2 – The Seattle Mariners rout the Chicago White Sox, 15–4, as outfielder Mike Cameron becomes the thirteenth player in Major League history to slug four home runs in a single game, all solo shots. In doing so, he becomes the first American League player in 43 years to accomplish the feat. Cameron is also hit by a pitch and flies out to deep right field in a bid for a 5th homer.
