2.) Alyssa Nakken
The Giants interviewing their assistant coach, Alyssa Nakken, was big news across the league as she was the first known example of a woman interviewing for a MLB managerial opening. Despite a vocal minority not being happy about that happening, Nakken's candidacy should not be ignored as she has already had to disprove plenty of doubts previously to get to where she is today.
A big league coach since 2020, Nakken has been a part of the organization since 2014 so she knows the players and organization well. There is also no denying that in order to break the glass ceilings she has, her performance has had to be top notch to even get her foot in the door. It would be an outside-the-box hire to be sure, but that could be exactly what the Giants need even though her connections to Kapler may work against her here.
1.) Bob Melvin
As soon as the Giants dismissed Kapler, the biggest name that started to be thrown around as a potential option to replace him is Padres manager Bob Melvin. Melvin is one of the most respected managers in all of baseball with a track record of success that goes back to 2003. He also has connections to the Bay Area and the front office which could be a nice starting point for at least a conversation.
The biggest question about Melvin is whether or not he would actually leave the Padres. San Diego is clearly going for it right now, but there was a lot of drama around the Padres this season and the team really underperformed expectations overall. The whispers right now are that Melvin could be looking for the exit from that chaotic situation and if that is truly the case, he should be the Giants' top target among the known options available.
