The Giants’ list of candidates to become their next hitting and pitching coaches continues to evolve as other major league clubs shake up their staffs. But you can rule out two major names from franchise history. Barry Bonds is expected to continue in his mostly non-uniformed, special assistant role. And Matt Williams, who was around the club last season as a studio analyst for NBC Sports Bay Area, is also not considered a candidate to tutor hitters as part of Bruce Bochy’s staff. The Giants have a pair of openings because they reassigned longtime pitching coach Dave Righetti to an advisory position and shifted hitting coach Hensley “Bam Bam” Meulens to become the new bench coach. Former bench coach Ron Wotus, who had held that position since 1999, will replace the departing Phil Nevin as the third base coach. Giants GM Bobby Evans said the staff changes were about bringing in fresh perspectives to a club that lost 98 games last season while also putting two of Bochy’s most trusted and valued staff members in positions of influence. “Two of the most significant key leadership roles on the coaching staff are bench and third base,” Evans said. “It’s Boch’s two right-hand men, really, on the offensive and defensive side of the game. It’s important we have some strength there, and we feel good about both these guys.” Both Wotus and Meulens have aspirations to manage and have been candidates for openings with other clubs; it’s unclear whether either coach will be considered by the New York Yankees, who announced on Thursday that manager Joe Girardi will not be retained. Meulens came up as a player in the Yankees system. But it wouldn’t be the least bit surprising if the Giants had made certain assurances to Meulens that he would be a top candidate to take over after Bochy’s contract expires following the 2019 season. Evans did confirm that moving Meulens to bench coach will serve “his continued interest in developing his career and will provide him “an opportunity for his leadership to grow and for him to grow professionally.” But Evans was vague when asked what qualifications the club is seeking in new hitting and pitching coaches, saying that he values experience but also pointing out that Righetti had one year of coaching under his belt and former bullpen coach Mark Gardner was a coaching neophyte when they were elevated to their roles in 2000 and 2003, respectfully.
