The San Francisco Giants have the oldest average age in the major leagues at 30.63 years and the San Diego Padres have the youngest at 27.11, according to the commissioner's office.

Oakland is the second-oldest at 30.10, based on opening-day rosters, the commissioner's office said Friday. Washington is next at 29.84, followed by Colorado (29.59), Texas (29.58) and World Series champion Boston (29.53).

Among the teams with the lowest averages were the Chicago White Sox (27.57) and Baltimore (27.79).

The overall major league average of 28.92 was up from 28.91 on opening day last year.

More spring training for Yankees' Farquhar

Danny Farquhar will remain at extended spring training with the New York Yankees rather than start the season with a minor league team.

The 32-year-old right-hander collapsed in the Chicago White Sox dugout on April 20 because of a ruptured aneurysm and brain hemorrhage. He appeared in three spring training games, giving up six runs, four hits and five walks over two innings.

Farquhar signed a minor league contract with the Yankees during the offseason.

New York announced minor league roster assignments Friday.

Minor leagues apply new pitchers rule

Leagues at minor league baseball's two highest levels will use the experimental rule requiring pitchers to face at least three batters or end the half-inning, unless injured.

The National Association of Professional Baseball Leagues said Friday the rule will be used at Triple-A and Double-A.

Major League Baseball proposed the rule to the players' association, which refused to agree to its use in the major leagues this year. MLB intends to institute the rule for 2020.

Former All-Star faces child sex charges

A Texas grand jury has indicted former All-Star and World Series MVP pitcher John Wetteland on three counts of continuous sexual assault of a child.

The indictments Thursday in Denton County, north of Dallas and Fort Worth, follow Wetteland's January arrest. He's accused of making a child repeatedly perform a sex act on him.

A phone number couldn't be found for him Friday and it's unclear if he has an attorney.

Wetteland was the Most Valuable Player of the 1996 World Series when he helped the New York Yankees beat the Atlanta Braves. He posted four saves in that Series, which remains a major league record.
