Veteran manager Bob Melvin is leaving San Diego to become the next skipper of the San Francisco Giants, according to a baseball official with direct knowledge of the deal.

The official spoke to USA TODAY Sports on the condition of anonymity because the move has not been finalized yet.

Melvin led the Padres to the National League Championship Series last season and had one year remaining on his contract. But after a hugely disappointing 2023 season that ended with San Diego finishing 82-80 and missing the playoffs, the front office gave him permission to interview with their division rival -- which he did on Monday.

Sources tell The Athletic that Melvin, a three-time Manager of the Year and a Bay Area native, is expected to be officially named Giants manager later this week.

Melvin, who turns 62 on Saturday, began his managerial career in 2003, when he took over the Seattle Mariners from Lou Piniella. He spent two seasons in Seattle before moving to Arizona and winning one division title in five seasons.

Midway through the 2011 season, Melvin succeeded the fired Bob Geren in Oakland and began an 11-year stint with the A's. He won back-to-back AL West division titles in his first two full seasons and won another AL West crown in 2020 before the A's began a massive rebuilding project and allowed to take the Padres job at the beginning of last season.

In 20 seasons as a major league manager, Melvin's teams have posted an overall record of 1517-1425 (.516).

In San Francisco, he'll take over for Gabe Kapler, who led the Giants to 107 wins in 2021 but was fired with three games to go in 2023 as the team finished 79-83 -- three games behind Melvin's Padres for third place in the NL West.
