Edward Cabrera placed on injured list as Cubs' rotation crisis deepens

Edward Cabrera is on the injured list as of Wednesday, per FanGraphs, the latest entry in what has become the Cubs' most reliable rotation — the one populated entirely by pitchers who are not currently pitching.

What happened

Cabrera's placement on the IL arrived alongside that of Ben Brown, both going down on the same Wednesday, per FanGraphs. That brings Chicago's current count of sidelined starters to six, a number the report states explicitly and one that requires no editorial embellishment to land with appropriate weight.

The timing compounds an already difficult situation. Cubs president of baseball operations Jed Hoyer announced, per FanGraphs, that Justin Steele — who experienced a setback in late April while working back from his second Tommy John surgery — is not likely to rejoin the rotation this season. That announcement, layered on top of the Cabrera and Brown news, left the organization in urgent need of innings from somewhere.

The Cubs' response, per FanGraphs, was a trade with the New York Mets for left-hander David Peterson, a 2025 All-Star who has been getting lit up this year by FanGraphs' own description. Peterson is not arriving as a savior so much as a warm body capable of taking the ball, which, given the current circumstances, is a credential the Cubs are actively recruiting for.

Why it matters

The Cubs have navigated a turbulent season — FanGraphs notes a pair of 10-game winning streaks alongside a 10-game losing streak — with rotation health as the one constant, and not in the way a franchise would prefer. Injuries to starting pitchers have been the through-line all year, and Wednesday's news represents the latest chapter rather than an isolated incident.

What makes the Steele update particularly significant is the nature of the timeline. A player working back from Tommy John surgery operates on a long runway under the best circumstances; a setback in late April, per Hoyer's announcement as relayed by FanGraphs, effectively closes the door on a return this season. That is not a 10-day IL situation. That is a rotation slot that will not be filled from within.

For a club holding a playoff position, the gap between "we have David Peterson" and "we have a functional five-man rotation" is the operational question hanging over the next several weeks. FanGraphs is direct on this point: the Cubs will need significantly more help ahead of the August 3 trade deadline to hold their spot in the postseason picture. Peterson addresses the immediate need for a body to take the ball. He does not, by FanGraphs' own characterization of his current performance, address the need for a body that opposing lineups are finding difficult to handle.

Under general league roster mechanics, pitchers placed on the injured list are subject to a minimum 15-day IL stay, and a player can be transferred to the 60-day IL, which removes them from the 40-man roster count and creates additional flexibility. Whether any of Chicago's six sidelined starters are candidates for such a move has not been reported.

Where the club stands

The Cubs carry a record of 89-73 (.549), good for second place in the NL Central — though FanGraphs notes they are 14 games back in the division and eliminated from the division race. The playoff path runs through the Wild Card, where Chicago currently ranks second and sits +1.0 relative to the cut line. That margin is thin enough to feel every missed start and wide enough to feel like something worth protecting. The club enters this stretch on a one-game winning streak, which is the kind of detail that reads differently depending on whether your rotation is intact or currently a waiting room.

Is Peterson pitching soon?

Per the schedule, David Peterson is the probable pitcher for Saturday, June 27, at American Family Field against the Milwaukee Brewers, with Kyle Harrison projected as the opposing starter. That is a quick turnaround from the trade to a scheduled appearance, which speaks to how immediately the Cubs needed him slotted in.

Before that, Chicago sends Matthew Boyd to the mound Thursday, June 25, at Citi Field against the New York Mets — the very team from which Peterson was just dealt, which is either poetic or just the schedule being the schedule — with Freddy Peralta as the probable for New York. Friday, June 26, brings Colin Rea against Jacob Misiorowski in Milwaukee.

At +1.0 above the Wild Card cut line, there is no margin for a prolonged rotation collapse, which is precisely the context in which six starters on the injured list becomes a front-office emergency rather than a depth chart inconvenience.

What we don't know yet

The specific nature of Cabrera's injury has not been reported by FanGraphs, nor has a timetable for his return. The same applies to Ben Brown, whose IL placement was announced alongside Cabrera's but whose situation has not been detailed in the available reporting.

Hoyer's announcement about Steele establishes that a return this season is not likely, but the precise contours of that setback — beyond the late-April timing — have not been reported. "Not likely to rejoin the rotation this season" is the characterization FanGraphs attributes to Hoyer, and that is where the certainty ends.

Whether the trade for Peterson represents the full extent of Chicago's deadline activity is also unresolved. FanGraphs is explicit that the club will need significantly more help before August 3 to hold their playoff position, but what form that help takes, and from where, remains to be seen.

Peterson's recent performance — described by FanGraphs as getting lit up this year despite his 2025 All-Star selection — raises its own questions about how much stabilization he can actually provide. The report does not quantify that performance beyond the characterization, and the characterization is not one that invites uncritical optimism.

What to watch

The August 3 trade deadline is the obvious horizon. FanGraphs frames it as the moment by which the Cubs will need to act more substantially if the playoff position is to hold, and the rotation situation as currently constructed makes that framing hard to argue with.

Peterson's Saturday start against Milwaukee will be an early data point, though one game tells you very little about a pitcher FanGraphs describes as struggling this year. The more meaningful signal will come from whether the Cubs add another starter — or multiple starters — before the deadline, and whether any of the six currently sidelined arms offer a realistic return timeline that the organization has not yet disclosed.

The Wild Card margin of +1.0 above the cut line is the number to watch in the standings. It is not a comfortable number. It is the kind of number that makes a general manager's phone very busy in late July.
