Giants move Keaton Winn to 15-day IL with elbow neuritis, recall Reiver Sanmartin

The San Francisco Giants placed right-hander Keaton Winn on the 15-day injured list with right elbow neuritis, retroactive to August 19, the club announced on August 20. The move keeps Winn sidelined for the immediate stretch of the season while his elbow condition is addressed.

To fill the opening created by Winn’s IL placement, the Giants recalled left-hander Reiver Sanmartin as the corresponding roster move. Sanmartin’s promotion sets up another look at the Giants’ rotation and bullpen depth in a period when teams typically tighten their usage of available arms.

Elbow neuritis is a nerve-related irritation that can affect pitching mechanics and comfort, which is why MLB clubs often manage these situations with short-term roster moves rather than rushing pitchers back. For the Giants, the practical impact is a reduced set of innings options, with San Francisco needing to distribute outs across the remaining starters and relievers.

Winn’s absence, at least in the immediate term, is not described as a major on-field loss in the team’s current operational picture, according to the report that surfaced the transaction. The Giants are in the late-season phase where clubs commonly prioritize long relief, spot starts, and matchups to cover the ground without overextending arms.

From a roster-management standpoint, the Giants’ decision also reflects how quickly pitching depth can be consumed by health setbacks late in the year. Even when a club still has capable arms available, losing a starter or swing option forces more frequent decisions for catchers, managers, and bullpen usage.

What to watch next is the timeline associated with Winn’s neuritis recovery. The injured list designation is only the first step, and a later activation decision will depend on how the elbow responds to treatment and whether he can regain the type of pitching rhythm needed for a return.

For Sanmartin, the recall creates an immediate opportunity to contribute, either as a bullpen lefty or potentially in longer relief, depending on how the Giants shape their remaining days and matchups. His role will be a key barometer for how San Francisco views the current health of its pitching staff and how it intends to cover the gap created by Winn’s IL stint.
