Giants to hire Curt Young as pitching coach

The Giants are expected to hire former A’s pitching coach Curt Young to replace Dave Righetti as pitching coach in San Francisco, according to major-league sources.

The Giants have not confirmed the hire, but a deal appears to be done or close.

Young, 57, has been the A’s pitching coach twice, from 2004 to 2010 and again from 2012 through last June, when they fired him amid a poor performance by the Oakland pitching staff. The A’s were one of the worst defensive teams in baseball, which contributed to the pitching downfall.

He was the Red Sox’s pitching coach for one season, 2011.

Young was a left-handed starter for Tony La Russa when the A’s won three consecutive American League pennants, from 1988-90, and the 1989 World Series against the Giants. Later in his career he became a reliever.

Young will be the third new Giants coach to come from organizations that stress advance analytics, joining hitting coach Alonzo Powell (Astros) and bullpen coach Matt Herges (Dodgers).

The only remaining vacancy on the Giants’ staff is assistant hitting coach.

Righetti and bullpen coach Mark Gardner were moved into front-office roles. Hitting coach Hensley Meulens has become bench coach, with bench coach Ron Wotus becoming the third-base coach in place of Phil Nevin, who was not retained.
