A young player, he has been a fringe squad member this season (12.1% of available minutes). His defensive output reads 4.39 tackles, blocks and interceptions per 90. Below: strengths, watch-points, market-value outlook and the latest transfer news on Joyner.

Year-on-year, that's broadly in line with last season (Season 7 → 7). Over the 3 seasons on record his form has trended upward, peaking in 2025/26.
On long-term talent our Rating reads 38. At 19 Joyner is still climbing toward his ceiling, and a market index of 5.7 reflects that trajectory.
Output in context · St. Louis City finished 13th of 15 · a relegation-threatened side
4.39 tackles, blocks & interceptions per 90 — solid defensive volume, with 1 clean sheet across 13 appearances. Doing that for a relegation-threatened side (13th of 15) is harder than the bare numbers suggest: a back line under more pressure has to defend more often and protects fewer leads, so the volume — and any clean sheets — carry real weight. Going forward he chipped in 1 goal and 0 assists — a useful bonus from the back.
Strengths
- Attacking threat. Chips in from deep: 0.24 goal involvements per 90, useful for a central midfielder.
- Defensive volume. 4.39 tackles, blocks & interceptions per 90 — does the unseen work.
Watch points
- Game time. Only 12.1% of available minutes — needs a settled run to prove the level.
- Level. Rates below a nailed-on top-tier starter on our model.
Outlook
Rated 38.2 overall — developing / rotation level. Defensively he reads as solid defensive volume (4.39 tackles, blocks & interceptions per 90). At 19 the trajectory points up — potential sits near its ceiling (99/100) and market value should climb as minutes and output follow.
