The top catching prospect was expected to start the season in Triple-A Sacramento, however, with the minor league season canceled, Bart is a part of San Francisco's 60-man roster.
That doesn't mean he will start in the big leagues, though. No matter what Posey decides, the Giants don't want to force Bart up.
Before the No. 2 pick in the 2018 MLB Draft makes his debut, general manager Scott Harris would like to see two key parts of development grow for Bart.
“A couple of developmental priorities for him will be first to improve the game calling," Harris said Thursday on KNBR's "Murph & Mac" show. "Not that we’re at all concerned about his game calling, I just think there is a critical mass of games you need to catch at the minor league level before you’re fully prepared to call a game in the big leagues."
Bart actually called games at Georgia Tech, something that even Matt Wieters wasn't allowed to do from the same college coach. Harris is right, though. Calling games is a skill that catchers must continue to grow and the Giants hoped that would happen for Bart in Sacramento.
The second part to Harris' answer might be even more important for Bart and the Giants.
“The other thing we talked about quite a bit is we want to expose him to other positions on the field," Harris said. "Not because we are concerned about his catching at all, we already think he is a plus receiver and thrower, but because one of the main tenants of our developmental philosophy is versatility.
"We want to give our major league manager as many opportunities as possible to get our best bats in the lineup. We think the demands of the catching position are such that that it is a benefit of both the player and the team to be able to play multiple positions.”

Since the Giants drafted Bart, he hasn't played anywhere on the field other than behind the plate. The same goes for his college career. Learning a new position would have been a perfect opportunity for Bart in the Arizona Fall League, but he fractured his thumb hitting in the AFL.
Now Bart will have Summer Camp to learn a new skill, making the name of spring training 2.0 that much more fitting. He will be in camp with Patrick Bailey, a fellow catcher who the Giants took in the first round of the draft this year. It wouldn't be a surprise if the Giants had Bailey work on another position as well.
Versatility is the name of the game for the Giants and the rest of baseball right now. Bart currently is lacking it, though that soon could change. He has a strong arm behind the plate and moves well for his 6-foot-2, 238-pound frame. It will be interesting to see if the Giants simply hand him a first baseman's mitt, or if he learns another position like third base or the outfield.
“The more that Joey can move around, the more options that his major league manager is going to have to get his bat in the lineup, and I think that’s really important for his career and for the future of the Giants," Harris said.
Bart could find his way to a major league game during this 60-game season. The Giants will make sure they feel he is 100 percent ready first, though. There's no doubt he holds a key to San Francisco's future success, and there's no reason to rush and open that door too soon.
