Adon, 30, was awful in his seven appearances with Triple-A Worcester with an ERA of 11.88 and K/BB of 12/10 over 8 1/3 innings of work. The right-hander will now be free to find another team, but interest may be scarce at this stage.

Adon apparently injured his right shoulder while pitching for Toros del Este in the Dominican Winter League. The 26-year-old probably won't be fully recovered by the beginning of the 2021 regular season.

Adon was non-tendered by the Giants last week, but the two parties have now worked out a new deal for the 2021 season. Adon, 26, has yet to appear in a major league game and posted a rough 4.72 ERA and 1.59 WHIP in 55 1/3 innings of relief between Double-A Richmond and Triple-A Sacramento in 2019.

Adon recently exited a Domincan winter league appearance with an apparent arm injury, which is likely the reason for this move. He isn't arbitration-eligible and is arguably the team's top relief prospect, so the Giants might want to see if they can bring him back on a minor league deal.
