Carson Whisenhunt returns as Giants pitching staff faces slew of injuries originally appeared on NBC Sports Bay Area
SAN DIEGO — The description that Giants manager Bob Melvin gave Thursday morning was about the last one you want to hear during a season.
“We’ve got a full MRI tube,” he said.
Landen Roupp is headed back to San Francisco to get an MRI on his left knee, but he won’t be alone. Right-handed prospect Blade Tidwell will also get an MRI on Thursday afternoon after he felt shoulder discomfort. The Giants are hopeful on both, but also realistic. There’s a good chance that both young right-handers have thrown their final pitch of the 2025 season.

Tidwell’s injury was horribly timed, as he appeared next in line to join the rotation. Acquired at the deadline in the Tyler Rogers deal, Tidwell struck out 23 in his first 16 innings with the Sacramento River Cats and posted a 1.69 ERA over three starts.
Fellow prospect Carson Whisenhunt joined the Giants in San Diego on Thursday and he’ll start Friday night against the Milwaukee Brewers, allowing the staff to give Logan Webb (Saturday) and Robbie Ray (Sunday) an extra day of rest. After that, the Giants will recalibrate.
Kai-Wei Teng had been in the rotation but he was optioned back to Triple-A on Thursday. The Giants also optioned outfielder Grant McCray and called up hard-throwing right-handed reliever Joel Peguero, who was the talk of camp but struggled early in the Triple-A season.
Peguero at least provided some smiles on Thursday. The 28-year-old is thrilled to be on the verge of his MLB debut and said his wife and family members all cried when told the news. A few relatives plan to join him in Milwaukee this weekend.
“We’ve waited for this moment,” Peguero said. “They were so happy.”
Luis Matos also returned and went right into the starting lineup. The staff is going to try to give him some additional starts against right-handed pitching to see if he can get going.
Another Setback
Lefty Erik Miller is another pitcher who is running out of time given how late in the season it is. Miller’s rehab assignment was halted last week because he felt something in his elbow, but an MRI came back clean from a structural standpoint.
Still, Miller will be shut down for at least two weeks because of lingering inflammation in the elbow. He went on the 60-day IL on Thursday.
Miller went on the IL on July 3 and at this point there seems little reason for the Giants to get him back on a big league mound this season. They need a healthy Miller next season, not just to give them a go-to lefty, but also another hard-throwing option in the late innings. Had his rehab gone smoothly, Miller would have joined Randy Rodriguez and Ryan Walker in the late-game mix.
Some Good News, For Once
Matt Chapman has been fielding grounders and taking swings at Petco Park and all signs point toward the third baseman returning on Saturday in Milwaukee. Chapman got a cortisone injection in his aching right hand last week and said it worked wonders.

When Chapman returns, Casey Schmitt will slide back to second base, which now looks like his long-term home.
