Giants select contract of 28-year-old right-hander

The San Francisco Giants announced a series of roster moves on Thursday, recalling outfielder Luis Matos and selecting right-hander Joel Peguero. In corresponding active roster moves, they have optioned outfielder Grant McCray and right-hander Kai-Wei Teng. Left-hander Erik Miller has been transferred to the 60-day injured list to open a 40-man spot.

Peguero, 28, makes it to the majors for the first time. It was a long journey. He originally signed with the Rays as an international amateur way back in 2016. Even then, he was a bit on the old side, as most international amateurs sign when first eligible at 16 and have verbal deals well before that. That was Peguero’s age-19 season.

In the following decade, he spent many years with the Rays but eventually moved around to the Rockies, Nationals and Tigers without getting a major league call. He signed a minor league deal with the Giants coming into 2025.

He has thrown 42 1/3 Triple-A innings this year with a 5.10 earned run average. That’s obviously not a great number, but it’s come in the hitter-friendly Pacific Coast League and Peguero has a .353 batting average on balls in play and 68.3% strand rate this year, both unfortunate numbers. He is averaging close to 100 miles per hour on his two fastballs while also throwing a cutter, slider and changeup around 90 mph. That arsenal has helped him strike out 24.1% of batters faced, though also with a 12% walk rate.

The Giants have fallen to 6.5 games back of a playoff spot, so they are surely leaning towards decisions that prioritize the future over this year. They sold at the deadline and can now use the remainder of the season to get looks at some other players. They can throw Peguero out there in front of big league hitters and see how they handle his fiery stuff. If he can get outs, perhaps he can earn a role on next year’s club.

Sending Teng down to the minors opens a job in the rotation. Manager Bob Melvin tells reporters, including Shayna Rubin of the San Francisco Chronicle, that Carson Whisenhunt will be coming up to start Friday’s game. However, Landen Roupp is also going on the injured list. It was reported on Wednesday that Roupp has a left knee sprain and is going on the IL.

Justin Verlander is starting Thursday’s game, with Logan Webb and Robbie Ray scheduled for Saturday and Sunday. The Giants are off on Monday, so it’s theoretically possible that they go back to Verlander on Tuesday. They will need another starter at some point, however, as Tuesday’s game will be the first of nine in a row. Carson Seymour and Tristan Beck are currently working long relief roles, and one of them could make a spot start, though the club also has several pitchers on optional assignment who could be recalled.

As for Miller, he landed on the 15-day IL in early July due to a mild sprain of the ulnar collateral ligament in his throwing elbow. He started a rehab assignment this month, but the club informed reporters this week that a recent MRI showed more inflammation and that he’ll be shut down for another two weeks. Susan Slusser of the San Francisco Chronicle was among those who relayed that update.

Miller’s 60-day count is retroactive to his initial IL placement, so he’ll be eligible for reinstatement in early September. However, based on the most recent information, it seems like he’ll just be finishing his shutdown period at that time. Even if he’s declared healthy at that point, he would likely need a bit of time to ramp up and go on another rehab assignment.
