Reese was everything you could want in a backup in 2019; good defender, average bat. Depends how much stock you'd place on his 19 games in 2020. I think they should start the season with Jansen as the starter with Reese backing up, Kirk in AAA. If one of them falters, call Kirk up. If they both play good, maybe look into moving one. Their value should rebound, Jansen had an extremely low babip last year and if he can bring that up along with keeping his improved BB%.
