Logan Webb Lands on IL With Knee Bursitis, Giants Rotation Takes a Major Hit

Logan Webb is heading to the 15-day injured list with right knee bursitis, the Giants announced, with the move backdated to May 6. Trevor McDonald gets the recall to fill the roster spot. Per NBC Sports' Alex Pavlovic, the organization expects Webb back at first eligibility — but that's the optimistic projection, and knee injuries have a way of stretching timelines.

Webb is the undisputed anchor of this rotation. He's the kind of pitcher who suppresses run environments by design — ground-ball heavy, walks almost nobody, works deep into games. When he's on the mound, San Francisco becomes a fundamentally different team to bet on. His presence alone typically shaves a run off what opposing offenses can expect to produce. Bursitis in a pitcher's plant-leg knee is not trivial; it affects drive, follow-through, and the ability to repeat a delivery under load. The Giants are right to be cautious even if they're publicly telegraphing a quick return.

McDonald, 24, has shown flashes at Triple-A but offers a completely different profile — he's not a ground-ball machine, and his command doesn't project to Webb-level efficiency at the big-league level. Any start he makes in Webb's absence is a significant downgrade, both in actual performance terms and in how sharps will price the Giants' run environment.

For bettors, the calculus shifts immediately on any Webb-scheduled start that now goes to McDonald or another fill-in. SF team totals that might have sat at 3.5 or 4.0 against a tough opponent with Webb pitching deserve a hard look on the over — opposing offenses will legitimately get more. Conversely, opponent team totals and first-five innings lines that were suppressed anticipating Webb need to be repriced upward. Strikeout props are also relevant: Webb consistently clears his K lines at a high rate; McDonald does not carry the same punchout upside, so any residual K props priced to Webb's profile are now dead value.

Watch the Giants' game-by-game pitching confirmations closely over the next two weeks. Every night McDonald or an emergency arm takes the ball instead of Webb is a night where the SF under loses its biggest structural support and opponent run-scoring angles open up. Until Webb is confirmed back and healthy — not just eligible — treat San Francisco's pitching-dependent team totals and first-five lines as compromised.
