SAN FRANCISCO — Greg Maddux earned his 348th career win, Adrian Gonzalez went 4-for-5 with a homer and four runs, and the San Diego Padres spoiled the San Francisco Giants' first home opener since cutting ties with Barry Bonds by winning 8-4 today.

The Giants celebrated the 50th anniversary of their move from New York without the player responsible for the bulk of the team's highlights the past 15 seasons. The team decided not to bring Bonds back after he broke Hank Aaron's career home run record last season, and the slugger remains unsigned.
