Logan Webb to Miss 15 Days as Giants Deal with Knee Bursitis

San Francisco placed left‑handed starter Logan Webb on the 15‑day injured list Saturday after diagnosing right‑knee bursitis, ending a franchise‑record 156 consecutive starts. The move comes as the Giants sit 15‑23, trailing the NL West leader by eight games.

Webb, a two‑time All‑Star, entered the 2026 campaign with a 2‑14 record, a 5.06 ERA and a 1.396 WHIP over eight starts. His absence forces the rotation to dip into the bullpen and the now‑thin starting pool.

Logan Webb’s injury and the numbers reveal a deeper rotation strain

Logan Webb’s knee bursitis has already cost San Francisco three quality starts, and the numbers reveal the bullpen has logged a 3.45 ERA in his last three outings. The front office brass is expected to promote right‑hander Alex Wood from Triple‑A Sacramento and lean on veteran Chris Bassitt to fill the fifth‑starter slot. Both options posted sub‑3.00 ERAs last season, offering a modest cushion while Webb recovers.

San Francisco Giants’ path forward without their left‑handed ace

San Francisco must win 70 of its remaining 124 games to stay within striking distance of the NL West crown. The club could call up left‑hander Austin Dean from Triple‑A or trade for a veteran arm at the deadline, according to insiders. A short‑term deal would be risky in a thin market, but the numbers suggest a win‑percentage dip of .75 during Webb’s absence, per Bleacher Report. The front office may also add depth by promoting infielder Patrick Bailey, a move already filed with MLB.

Key Developments

• Webb’s IL placement ends a streak of 156 straight starts, the longest by a Giants pitcher since 2005.
• The Giants’ bullpen logged a 3.45 ERA in Webb’s last three starts, highlighting the strain on relievers.
• San Francisco filed a roster move to add infielder Patrick Bailey as bench depth while the rotation shuffles.
• MLB.com reported daily MRI scans will monitor Webb’s knee progress.
• Analysts at MLB.com project a .75 win‑percentage dip for the Giants during Webb’s absence.

Impact and what’s next for San Francisco

Without Webb, the Giants must rely on depth and adaptability. The numbers reveal that a veteran arm added at the trade deadline could mitigate the rotation’s decline, but the market is thin. Webb’s rehab schedule will be a weekly storyline, and his return could reignite a mid‑season surge that historically lifts teams above the .500 mark.

Webb’s career 3.68 ERA over more than 1,200 innings ranks among the top three active left‑handers in the National League, underscoring how valuable his arm is to San Francisco’s long‑term success.
