James Anderson pinpoints relievers and potential relievers from the minor leagues who could develop into the next great fantasy baseball closer, including recent Angels draftee Ben Joyce.

James Anderson puts 94 pitching prospects into tiers for 2022 value only, with Rays righty Shane Baz leading a tier of three at the top.

James Anderson ranks the fantasy-relevant prospects in each NL Central farm system, including Pirates third baseman Ke'Bryan Hayes.

Jesse Siegel dives into the deep recesses of the minors to profile prospects like Texas pitcher Joe Palumbo.
2023 Fantasy Outlook
Bolton made a quick impression after being drafted in the sixth round by the Pirates in the 2017 MLB Draft. However, he entered 2022 having thrown only 171.2 innings as a professional while heading into his age-24 season. That said, it comes as little surprise that the Pirates handled his workload carefully, as he worked primarily out of the bullpen and rarely in longer than three-inning stints with Triple-A Indianapolis in 2022. His potential value to fantasy managers moving forward could hinge on how the Pirates use him in 2023, as they could opt to return him to a starting role. Assuming his body holds up, Bolton could be a back-end starter as scouting reports suggest he has three average pitches with average command. If he sticks in the bullpen, he likely doesn't have the velocity to work in high-leverage roles, leaving him irrelevant in most fantasy formats.
