Bret Boone's tenure as rookie Victoria Seals field manager has lasted only five games into the Golden Baseball League season.

The former Seattle Mariners second baseman has resigned over what he described as personal and family issues.

The former American League and National League all-star has returned to be with his family in San Diego.

"This was a very difficult decision for me," said Boone in a prepared statement on the team's website. "I am disappointed that I won't be able to be with the team throughout the rest of the season, but after a lot of consideration, I have decided that this is the best move for both me and my family."

No explanation was given by Boone or the team about the situation that caused Boone to resign. The Seals would only say he is returning home to be with his family.

"At this time the Victoria Seals will reserve any further comment, and ask that both members of the media and the public respect the Boone family's privacy during this time," said the club, in a release.

Assistant coach Kip Gross, a former major-league pitcher, will take over as field manager on an interim basis, starting Thursday night when the Seals play the undefeated Orange County Flyers at Royal Athletic Park. Catcher Josh Arhart and third-baseman Brian Rios will become playing coaches.

The 41-year-old Boone guided the Seals to a 3-2 start in the season-opening series against Maui. He was hired March 8 to replace former major-league slugger and ex-Victoria manager Darrell Evans, now manager of the St. George Roadrunners of the GBL.

"It's an unfortunate development for our organization, but in no way do we view this as a setback for the club," said Seals president Darren Parker, in an interview this morning.

"It's business as usual for us at the ball park. The product has not changed at all. Bret was pretty upset when he informed me. He did not want to leave the guys. But he needs to get to his wife and kids and deal with some personal issues. And we respect that. We wish Bret the best in dealing with his family situation."

Parker said a search is on to replace Boone and that Gross will be considered for the full-time managing position.

"We believe we are in capable hands. We are also entertaining a lot of options," said Parker.
