Jared Jones reportedly expected to return to Pirates rotation this weekend

Jared Jones is expected to return to the Pittsburgh Pirates' rotation this weekend, per a FanGraphs chat hosted by Dan Szymborski on May 28. The note surfaced inside a reader question about how Pittsburgh might configure its pitching staff around Jones's return — which, as these things go, is about as tidy a rotation puzzle as a team can hand itself on a Thursday afternoon.

What happened

During the FanGraphs chat, a reader asked Szymborski whether the Pirates would be better served running a six-man rotation upon Jones's return or sending Chandler down given his control issues. The framing of the question — and Szymborski's answer — treats Jones's return as an imminent development, though no official club announcement accompanied it. Jones is listed as Pittsburgh's probable starter for Friday, May 29, against the Minnesota Twins at PNC Park, opposite Taj Bradley. That listing is the closest thing to a formal signal available, and probable pitchers can change.

The FanGraphs chat does not specify the nature of the injury that sidelined Jones, nor does it offer a timeline for how long he has been out. What the exchange establishes is the expectation of a return — not a confirmation of one.

Why it matters

The question a reader brought to Szymborski was genuinely operational: does Jones's return create a roster crunch, and if so, how do you solve it? Szymborski's answer leaned toward keeping Chandler in the mix rather than sending him down, citing Chandler's solid first-strike percentage as a leading indicator of future walk rate. That is a meaningful distinction — a pitcher who throws first-pitch strikes tends to find the zone more broadly over time, even if the walk numbers have not caught up yet. Szymborski's preference, per the FanGraphs chat, was a six-man rotation rather than an outright demotion.

The mechanics here are worth a brief note. Under general league rules, a pitcher on the injured list can be given a rehab assignment of up to 30 days before the club must activate him or make another move. Whether Jones has been on a rehab assignment, or simply on the injured list without one, is not addressed in the FanGraphs chat. What the probable-pitcher listing suggests is that the Pirates are at least planning around his availability for Friday.

Where the club stands

Pittsburgh is 82-80 (.506), sitting third in the NL Central, 21 games back in the division, and eliminated from both the division race and the Wild Card race. Their Wild Card rank sits at 5, with a figure of 6.0 relative to the cut line. They carry a one-game winning streak into Thursday's home game against the Chicago Cubs, where Paul Skenes is listed as the probable starter opposite Colin Rea.

Those numbers frame the rotation question in a particular light. When a team is playing out the string — however competitive the individual games remain — the calculus around innings limits and development shifts. Szymborski's preference for keeping Chandler in the rotation rather than sending him down makes a certain kind of sense in that context: there is developmental value in letting a young pitcher work through his command issues at the major-league level, especially when the standings pressure is limited. The first-strike percentage argument is not a small one, either. It is the kind of leading indicator that tends to get overlooked when walk totals are the headline number.

If Jones does take the ball Friday, it would be his first start back from whatever has kept him out. Saturday's probable matchup has Mitch Keller going against Bailey Ober, also at PNC Park. The Pirates are playing all three games of this stretch at home, which is a reasonable environment in which to reintegrate a starting pitcher — familiar mound, familiar surroundings, no travel between outings. Whether that schedule was a factor in the timing of a potential return is not addressed in the FanGraphs chat, but the calendar cooperates either way.

What we don't know yet

The FanGraphs chat does not name the injury, does not specify how long Jones has been sidelined, and does not include any direct statement from the club or from Jones himself. The return expectation comes from the framing of a fan question in a public chat and from Szymborski's response — not from a Pittsburgh Pirates announcement. Probable pitchers are subject to change, and nothing in the available material constitutes a guarantee that Jones starts Friday.

It is also unclear whether the six-man rotation Szymborski discussed is something the Pirates are actively considering or simply a framework a reader proposed. Szymborski expressed a preference for it, but that is an analyst's view, not a club decision. Similarly, the question of Chandler's future — a demotion or continued major-league role — remains open. The FanGraphs chat addressed it as a hypothetical, not as a pending transaction.

What to watch

The Friday probable-pitcher listing is the most concrete signal available. If Jones is indeed on the mound against the Twins and Taj Bradley at PNC Park, that would represent the practical realization of what the FanGraphs chat flagged as an expectation. Watch also for any roster move the Pirates make before or around that start — under general league rules, a pitcher returning from the injured list requires a corresponding roster transaction, which would clarify the situation considerably.

The broader rotation question Szymborski engaged with — six men or five, and what happens to Chandler — is worth tracking across the coming days. Szymborski's read on Chandler's first-strike percentage as a leading indicator gives the Pirates a reason to be patient, but patience has its own roster math. How Pittsburgh manages that balance, with Jones potentially back in the picture and the standings pressure largely resolved, will tell you something about what this organization is prioritizing in the final stretch of the season.
