Giants third base prospect Adam Duvall went 1-for-5 with his 21st home run of the season on Sunday. Duvall seems to be stuck in Triple-A, hitting a spectacular .294/.358/.628. Duvall has six home runs in June, and is only three behind the minor league lead of 21. He is blocked in San Francisco, but could be an option if there is an injury at either corner infield position.
