Tennessee pitching coach Frank Anderson is set to join Tony Vitello with the San Francisco Giants, On3’s Chris Low has learned. Anderson has informed Tennessee coach Josh Elander of his departure.

In the meantime, Tennessee is set to name Anderson’s replacement. Elander is staying in-house, promoting Josh Reynolds to pitching coach, Low reported.

Anderson had been on Tennessee’s staff since 2017 and remained with the program after Vitello took over the program in 2018. He previously worked as an assistant at Texas Tech, Texas and Houston, and was the head coach at Oklahoma State from 2004-12. During that time, he had a 329-208 record and led the Cowboys to six NCAA Regionals, along with a Super Regional.

Frank Anderson’s exact role with the Giants remains unclear. San Francisco is set to name a pitching coach in Justin Meccage, who was previously with the Milwaukee Brewers’ minor league system, according to Fansided’s Robert Murray.

Vitello continues to round out his staff in San Francisco after making the historic move from the college ranks to the major leagues. Former San Diego Padres manager Jayce Tingler is coming aboard in an unspecified role, and hitting coach Pat Burrell is also preparing to stay with the organization. He won’t be on Vitello’s staff, though, according to NBC Sports Bay Area’s Alex Pavlovic.

Three coaches – assistant hitting coach Oscar Bernard, quality control coach Taira Uematsu and bullpen catcher Eliezer Zambrano – are staying on staff, Giants president of baseball operations Buster Posey said at the general manager meetings. First-base coach Mark Hallberg and catching coach Alex Burg could also stay on board.

As Vitello builds the staff, Posey said the front office will have some input in the process. He called it a collaborative process as the former Tennessee coach adjusts to live in the big leagues.

“We’re certainly very much involved in the process,” Posey said, via MLB.com’s Maria Guardado. “I think Tony will tell you the same thing. It has been a collaboration, and I think you’re going to be most productive in that way. I don’t think it would be fair for me to come in and say, ‘I am going to choose every single person.’ That’s just not the way that I think is best, or vice versa for him to operate that way, as well.”
