2025 Fantasy Outlook
Spiers split time between the minors and majors in 2024, making 18 starts and an additional 13 appearances as a reliever. The right-hander excelled at Triple-A Louisville, where he was used as a starter, posting a 2.51 ERA while lowering walk and home run rates. His results in the majors, however, were less glamorous either as a starter or reliever. As a starter, MLB hitters crushed 16 homers off him in just 51.2 innings. The numbers were slightly better coming out of the bullpen, but those appearances were primarily as an inning-eater in low-leverage situations. He's likely to begin 2025 in the rotation at Louisville, as he did last season, and provide starting depth for the Reds. Read Past Outlooks

Rehab moving to Triple-A
PCincinnati Reds
Shoulder
July 6, 2025
Spiers (shoulder) is expected to have his rehab assignment shifted from the rookie-level Arizona Complex League to Triple-A Louisville on Tuesday, MLB.com reports.
Analysis
Spiers made his lone appearance in the ACL on Wednesday, allowing two hits while striking out four and hitting a batter over 2.1 scoreless innings. He threw 49 pitches in that outing and will look to build on that workload Tuesday, when he's expected to piggyback fellow rehabbing right-hander Hunter Greene (groin). Spiers look on track to rejoin the Reds after the All-Star break and will likely fill a multi-inning role out of the bullpen after he started in two of his three appearances for Cincinnati before landing on the shelf April 20 due to a right shoulder impingement.

2024 Fantasy Outlook
Spiers fared well in his second go-round at Double-A Chattanooga in 2023 and was needed for MLB innings during the Reds' push for the postseason in September. In the minors, the right-hander's walk rate inched up, but Speirs' improved location within the strike zone resulted in a better strikeout percentage and significantly lowered home run rate. Desperate for pitching help in the majors, the Reds summoned Spiers from Double-A for four appearances (two starts) that went predictably awry. Spiers' name will be mentioned when talking about the team's starting depth, but he could spend the entire season in the minors.
