In a devastating blow to their postseason hopes, the San Francisco Giants lost emerging No.3 starter Landen Roupp to a left knee sprain during Wednesday's 8-1 loss to the San Diego Padres.

Roupp was carted off the field after taking a comebacker, only five days removed from returning from the injured list with elbow inflammation. The timing couldn't be worse: Roupp had stabilized the middle of San Francisco's rotation, logging a 3.80 ERA over a career-high 106 2/3 innings in 22 starts this season.
The Giants' staff has quietly been a strength this year, ranking fifth in MLB with a .372 ERA across more than 1,100 innings. Behind Logan Webb and Robbie Ray, Roupp had emerged as the club's most dependable starter, giving manager Bob Melvin a reliable three-man core. With Roupp now sidelined in definitely, the rotation picture becomes murky, and the internal solutions look anything but pleasing.
Blade Tidwell, acquired from the New York Mets in the Tyler Rogers trade, looked like he was on the verge of returning to the majors after posting a 1.69 ERA in his first three outings with Triple-A Sacramento. However, Tidwell felt shoulder discomfort during a bullpen session this week and is now awaiting MRI results, likely removing him from consideration down the stretch.
Tidwell's uncertain status forces the Giants' to look at two other options at Sacramento: Hayden Birdsong and Carson Whisenhunt, both of which are already on the 40-man roster.
Birdsong is an intriguing name, especially after showing promise earlier this season both as a reliever and in spot starts. Command issues have derailed Birdsong's opportunity to stay on the major league roster. Birdsong's latest outing at Triple-A saw him walk five batters over three innings. Since his demotion in late July, he's sporting a 5.59 ERA with the River Cats, suggesting he isn't ready to handle the pressure of a pennant race.
Whisenhunt has debuted already, flashing upside but inconsistency. He's had only one strong outing in three starts, and the Giants may be weary of relying heavily on him in meaningful August and September games. Carson Seymour could be stretched out after working as a multi-inning reliever, but he lacks experience as a starter. Trevor McDonald is another option, already on the 40-man roster, though his results in Sacramento have been uneven.
The reality is that none of these names inspire confidence as a dependable replacement for Roupp. Internal depth has been tested all year, and the injury now pushes the Giants to a breaking point. The front office may have to lean on bullpen games, gamble on a struggling prospect, or turn aggressively to the trade market in search of help.
Roupp's emergence as a dependable mid-rotation starter was one of the bright spots of the season for San Francisco. His absence magnifies how thin the margin for error is as the club pushes toward October. Unless someone unexpected steps up, the Giants rotation will remain one injury away from collapse.
