Baseball Notes: Report: Riggleman to guide Nats

Riggleman was promoted from bench coach to interim manager in July to replace fired manager Manny Acta. He has managed the San Diego Padres, Chicago Cubs, and Seattle Mariners.

The Nationals, who were 26-61 at the time, went 33-42 under Riggleman.

Mariners. Ken Griffey Jr. and Seattle agreed to another one-year contract. Griffey, who will turn 40 Nov. 21, was guaranteed $2 million when he signed to return to Seattle for the 2009 season and had the chance to earn more in bonuses. Next season will be his 22d in the majors. He is No. 5 on the career home run list with 630.

Red Sox. Jason Varitek exercised his $3 million option to stay with Boston after the team earlier this week declined to exercise its $5 million option.

Diamondbacks. Former Arizona slugger Matt Williams is joining the Diamondbacks as first-base coach.

A five-time all-star third baseman, the 43-year-old Williams will make his big-league coaching debut. He played for the club from 1998 to 2003 and has completed his fifth season as a team broadcaster.

Bo Porter will join manager A.J. Hinch's staff as third-base coach. Porter spent parts of three seasons with the Chicago Cubs, Oakland and Texas.

Glenn Sherlock will return as bullpen and catching coach.

Zambrano ordeal. The mother of former major-league pitcher Victor Zambrano was rescued after a three-day kidnapping ordeal, Venezuelan authorities said in Caracas.

The 56-year-old Elizabeth Mendez Zambrano was rescued late Tuesday during a "commando-style operation" in the state of Aragua, Federal Police Chief Wilmer Flores Trosel said.

Zambrano played for Tampa Bay, the New York Mets, Toronto, and Baltimore over seven seasons. The righthander had a career record of 45-44 with a 4.64 ERA.

He hasn't appeared in the majors since 2007 and plays in Venezuela's winter league.
