Sounds fine to me, Longenhagen is just one source BA has him as fine defensively...
Barger can play multiple positions on the infield. His sound actions and plus arm strength should allow him to stick at shortstop as an average defender, and he can also capably play second base or third base.
The Future: Barger's power and defense give him a chance to be a regular in the middle infield. He is in position to make his major league debut in 2023.

And there's Law on his defense...
He’s not a shortstop but he’s solid at third and I see no reason he couldn’t handle second. He could be a regular at either of those spots on a non-contender, whereas for a good club he’s a very good utility infielder who can handle short on a temporary basis and would also be a valuable pinch-hitter when he’s sitting against a lefty starter.
