The Giants will likely use 2020 as an opportunity for some of their prospects to get major league experience in an effort to see who will eventually replace the aging core of Posey, Belt, Crawford, and Longoria.
Top catching prospect Joey Bart already looks nearly ready for MLB action after going No. 2 overall in the 2018 draft. He has yet to play above the Double-A level, so it is most feasible that he starts the season at Triple-A.
A .284/.343/.532 hitter over 566 career plate appearances in the minors, Bart could put some serious pressure on the front office to find a place for him on the MLB roster if he begins 2020 with similar production at Triple-A Sacramento.
That could mean finding a way to move Belt in order to open up the first base job for Posey.
In much of the same position — waiting on the Giants to deal one of their large contracts to open up a spot — is third baseman Zach Green.
While he is not as high-profile a prospect as Bart, Green has proven to be a solid slugger in the minors having hit 20 and 25 home runs his last two seasons, respectively.
The 34-year-old Longoria does not fit the team’s plans moving forward, so he is a clear trade candidate. A deal would open up time for Green to prove whether or not he can hit against MLB pitching.
While the Giants have done well to restock their farm system over the past calendar year, the infield will still be occupied by many of the club’s high-priced, aging veterans to begin the 2020 season.
