On August 2, 1998 — Welcome to the Bigs. The Phils’ Mike Welch makes his first big league start and the Giants greet him with three consecutive homers in the 2nd inning. Newly-acquired Ellis Burks starts the fireworks, then Barry Bonds – who had tripled in the 1st inning – goes deep, then Jeff Kent drills his 15th. Welch takes the loss, allowing eight runs in three innings. Bonds is 4 for 4 with a stolen base to pace the Giants.
