Nakken, 29, was a college softball player at Sacramento State from 2009-12. She joined the Giants in 2014 as an intern in the baseball operations department and is currently responsible for directing many of the organization's health and wellness initiatives.

San Francisco also added Mark Hallberg to the staff. Hallberg, 34, served as manager of short-season Class A Salem-Keizer last season.

'Alyssa and Mark are highly respected members of the organization and I'm delighted that they will now focus their talents on helping to build a winning culture in the clubhouse,' new Giants manager Gabe Kapler said in a press release. 'In every organization, environment affects performance, and baseball clubhouses are no different.

'That's why in addition to assisting the rest of the coaching staff on the field, Mark and Alyssa will focus on fostering a clubhouse culture that promotes high performance through, among other attributes, a deep sense of collaboration and team.'
