The Giants already look like they came out ahead in the Robbie Ray trade with the San Diego Padres, but the size of that win could end up hinging on Miguel Mendez.
The right-hander, one of the two prospects San Francisco got back in the deal, has been turning heads in the Arizona Fall League. Through three starts, Mendez owns a 3.52 ERA across 7 2/3 innings, and his latest outing offered a strong flash of what makes him intriguing: five strikeouts in three frames.
Sam Dykstra of MLB.com also noted that Mendez’s velocity was sitting in the upper-90s, and that matters. He’s now racked up 12 strikeouts in the AFL, tied for the second-most among pitchers.
That kind of swing-and-miss is nothing new when Mendez is dialed in. In 2025, he piled up 118 strikeouts over 95 innings in the minors.
His slider is his top secondary pitch, and the real question is whether he can build a dependable third offering. If that happens, he’s the type of arm who could be in the big leagues in 2027, which is why he looms as such an important piece of the puzzle.
Mendez is 24 and reached Double-A at the end of the 2026 season. His time in Richmond wasn’t pretty - he posted an 8.44 ERA - but he’s expected to open next season there and get a chance to show that stretch was an outlier.
The timing matters for San Francisco, too, because the organization’s pitching depth has taken hits. Hayden Birdsong, Trevor McDonald, Carson Whisenhunt, and Blade Tidwell all underwent elbow surgery, leaving the Giants even thinner on the mound. That opens the door for Mendez to become part of the next wave if the rotation gets hit by more injuries.
He’s already on the 40-man roster, so it feels likely the Giants will get a look at him at some point next season. His role could take a few different forms: spot starter, long reliever, or even a full-time bullpen experiment.
If the starting route stalls, San Francisco could try to lean on just his fastball and slider and see what that looks like in relief. That pairing could make him a dangerous late-inning option.
The Giants have brought in a wave of young pitching talent, and if Mendez becomes one of the arms that helps at the major league level, Buster Posey and the front office will have every reason to feel good about the direction they’re taking.

Kyle Harrison Is Back On The World Series Stage Waiting To Matter
Kyle Harrison has reached the biggest stage in October with the Milwaukee Brewers, even if he has not yet had a chance to leave a mark on the playoffs. The 25-year-old left-handers presence on a World Series roster gives him a place in the spotlight, but his usage so far has been limited enough to invite a familiar comparison to the way Tim Lincecum was deployed during the Giants 2014 championship run.
For Giants fans, it is a reminder of how tricky October pitching decisions can be, especially when a talented arm is available but not yet central to the plan. Harrisons situation leaves open the possibility of a larger role in future playoff appearances, which is part of what makes his current wait so interesting: he is there, he is close, and the next time the moment finds him, it may matter much more.

Giants Face A Tough Steven Kwan Question This Offseason
Steven Kwan is heading into the final year of his arbitration window with Cleveland, which naturally puts him on the radar of clubs looking to add a dependable bat before he gets any closer to free agency. Around the league, executives reportedly expect the Giants and other teams to at least kick the tires, and it makes sense given how San Francisco has tried to keep one eye on immediate competitiveness while also planning ahead for the next wave of roster decisions.
Still, the Guardians have not been in the habit of letting key players drift all the way to the open market, so any real conversation would likely center on whether they can extract value now rather than later. For the Giants, the bigger question is whether Kwan fits their picture for the 2027 season, because their level of interest figures to hinge less on the name itself than on where they think the roster is headed by then.

Former Giants Could Be In Line For A World Series Ring
The postseason has a way of circling back on old faces, and a few former Giants are in position to feel that now. As the 2026 World Series looms, San Francisco fans have reason to keep one eye on Milwaukee and Tampa Bay, where several players who once wore orange and black have spent the season contributing in different ways, from regular roles to more limited depth spots.
It is the kind of detail that rarely matters in the standings but tends to resonate afterward, when rings are handed out and old affiliations come back into focus. Some of those ex-Giants have logged meaningful innings and plate appearances this year, while others have stayed more on the fringes of the roster, but either way their paths now run through a championship setting that could leave them eligible for a piece of the reward.
