Nick Lodolo placed on 15-day IL with blister on left index finger, Chase Petty recalled

Nick Lodolo is heading to the injured list. The Cincinnati Reds announced Saturday morning that the left-hander has been placed on the 15-day IL with a blister on his left index finger, a development that unfolded in real time during Friday's start against the Cubs. Right-hander Chase Petty was recalled from Triple-A as the corresponding roster move, per MLB Trade Rumors.

What happened

Lodolo worked through five innings against Chicago without serious trouble — one earned run allowed — before the sixth inning became something more than a pitching problem. He gave up a solo home run to Carson Kelly to open the frame, then was observed checking his left hand before calling for the trainers. The Reds pulled him from the game at that point, per MLB Trade Rumors.

His final line: five-plus innings, two earned runs, and 78 pitches. Caleb Ferguson took over on the mound following Lodolo's departure.

The 15-day IL is the standard placement for pitchers under general league rules, meaning Lodolo cannot return for at least 15 days from the date of placement. A blister on the pitching hand's index finger is the kind of injury that can resolve quickly or linger with maddening unpredictability — the skin operates on its own schedule, indifferent to rotation needs and pitching coach preferences alike. What the actual timeline looks like for Lodolo has not been reported.

Why it matters

A starting pitcher exiting mid-start reshapes a rotation immediately, and the Reds needed an arm the same day. That is where Petty comes in. The right-hander was recalled from Triple-A to fill the roster spot, giving Cincinnati a fresh option from the upper minors.

The broader context is worth sitting with: the Reds are 75-87 and have already been eliminated from both the NL Central division race and the Wild Card race. That changes the operational calculus around a move like this in meaningful ways. When a contender loses a rotation piece, the urgency is about October. When a club in Cincinnati's position loses one, the urgency shifts — toward development, toward getting a look at younger arms, toward understanding what the roster looks like heading into the offseason. Petty's recall fits that frame as naturally as it fills a practical gap.

There is also the matter of what a blister means for a pitcher's workload going forward. Even after a return, the skin on a pitcher's index finger takes friction on every pitch. Clubs tend to be cautious about rushing a pitcher back from a blister only to watch it reopen two starts later. The Reds have not said anything about their approach to Lodolo's return, but the 15-day floor is just that — a floor, not a ceiling.

The numbers

Lodolo's exit line from Friday — two earned runs over five-plus innings on 78 pitches — was a reasonable start interrupted, not a collapse. He had allowed just one earned run through his first five frames before the Kelly home run and the subsequent exit. The blister, not the performance, ended his night.

The Reds' season record sits at 75-87 (.463), placing them fifth in the NL Central and 28 games back in the division. Their Wild Card standing ranks ninth, 13.0 games relative to the cut line. They enter Sunday having dropped their most recent game, carrying a one-game losing streak into the series finale.

Those standings numbers provide the backdrop against which every roster decision this club makes carries a slightly different weight than it would in July for a contender. The 15-day IL placement costs the Reds a rotation turn from one of their better starters. In a pennant race, that is a crisis. At 75-87, it is a roster management question with a developmental dimension attached.

Where the club stands

Is Lodolo pitching Sunday?

He is not. Lodolo is on the 15-day IL as of Saturday morning, per the club's announcement relayed by MLB Trade Rumors. The series finale against the Cubs on Sunday, July 12, at Great American Ball Park features Andrew Abbott as Cincinnati's probable starter against Matthew Boyd for Chicago.

That means the Reds turn to Abbott the day after Lodolo's early exit, with Petty now available in whatever capacity the club chooses to deploy him. Whether Petty slots into the rotation, works out of the bullpen, or simply provides depth while Cincinnati evaluates its options has not been reported.

The Reds sit fifth in the NL Central, 28 games back, eliminated from the division and from Wild Card contention. The one-game losing streak heading into Sunday is the least of their concerns. The more pressing question is what the rotation looks like while Lodolo is unavailable, and how the club uses the opportunity his absence creates.

What we don't know yet

The return timeline for Lodolo is the obvious open question. The 15-day IL sets a floor, but blisters do not negotiate with calendars. There is no reported timetable for when he might be eligible to throw again, no reported severity assessment beyond the diagnosis itself, and nothing in the club's announcement — as relayed by MLB Trade Rumors — about what the next steps look like for his recovery.

The announcement covers the IL placement and the Petty recall. What it does not address is anything about Lodolo's expected recovery arc, whether additional treatment is planned, or how the Reds intend to manage his rotation spot beyond Petty's immediate recall. Those details may emerge in the coming days, but as of Saturday morning they remain unreported.

It is also worth noting that the 15-day IL can be extended. If the blister does not respond as hoped, a transfer to the 60-day IL is a possibility under general league rules — though nothing in the available reporting suggests that outcome is anticipated.

What to watch

The most direct follow-up question is straightforward: how long is Lodolo actually out? The 15-day minimum is the floor; the ceiling is unknown. Any update from the club on his throwing program or a projected return window would be the next meaningful data point.

Beyond Lodolo, Petty's role is worth monitoring. A recall from Triple-A in a rotation-adjacent situation can mean a lot of things — an emergency starter, a bulk-innings option, a long reliever — and the Reds have not specified. Given where Cincinnati sits in the standings, how the club uses Petty over the next several weeks could say something about how they are thinking about their younger arms heading into the offseason.

Sunday's series finale against the Cubs, with Abbott on the mound, is the immediate next game on the schedule. Lodolo will not be part of it. Whether Petty is — and in what capacity — is the first small answer the Reds will provide to a question that opened up Friday evening when a left-hander started checking his hand in the sixth inning at Great American Ball Park.
