​All seven of the San Francisco Giants’ minor league affiliates were in action on Tuesday as a fresh series kicked off for the A-ball squads, with a nod to Monday’s rookie-ball games as well. Here’s the rundown from the day, including the low-A and rookie-ball action, and a reference to the 2026 McCovey Chronicles Community Prospect List (CPL). In this roundup, every listed position reflects the role the player occupied in that specific game.
There was notable movement on the farm. Left-hander Cesar Perdomo was promoted from Double-A to Triple-A, an exciting development that seems partly merit-based and partly designed to position Carson Whisenhunt for a return to the majors. Replacing Perdomo in Richmond’s rotation is left-hander Tyler Switalski, who was promoted from High-A Eugene. On the hitter side, right-hander Chen-Hsun Lee and right-hander Samir Chires, along with outfielder Angel Guzman, were promoted from the Arizona Complex League to Low-A San Jose, while right-handers Mauricio Estrella and Ubert Mejias moved from San Jose up to Eugene. In addition, Low-A outfielder Jose Ortiz, Double-A right-hander Darien Smith, and Triple-A outfielder Grant McCray were assigned to rehab stints.
In Sacramento, the River Cats defeated the Salt Lake Bees (Angels) 7-6 in 10 innings. It was a quirky contest, as Sacramento faced a near no-hitter through seven innings before erupting for five runs in the seventh, tying the game in the eighth, and walking it off in the 10th. It wasn’t a showcase for standout performances on either side, so the finish via an error was a fitting end to an uneven night. The offense did have one bright spot: second baseman Nate Furman (No. 39 CPL) went 2-for-5 with a double—his only extra-base hit—and drove in two of the seven runs during the seventh-inning rally, while also recording a strikeout.
Furman has had a steady AAA rookie-year presence, offering consistent production rather than flash. The soon-to-turn-25-year-old is batting to a .765 OPS with a 107 wRC+ this season, values that have hovered near that level for much of the year. The Giants likely appreciate his 13.5% strikeout rate, a useful trait for a developing big-league roster.
Shortstop Osleivis Basabe delivered a solid day, going 1-for-3 with two walks and a strikeout. Basabe, a 25-year-old who was outrighted last year, provides valuable depth in AAA—hitting around league average (.739 OPS, 95 wRC+), showing a low strikeout rate (about 12.0%), and offering strong defensive versatility across the infield.
On the mound, the opening act featured a rough start for right-hander Tristan Beck, who was making his third appearance since being optioned. Working as the opener, Beck yielded three hits, two walks, and three runs over 2.1 innings, though he did strike out five. This marks Beck’s final option year, and he’ll need to show continued progress to secure a spot on next year’s roster given his season so far in both the Majors (6.75 ERA, 3.96 FIP) and AAA (4.34 ERA, 4.15 FIP).
Following Beck, right-hander Trent Harris (No. 29 CPL) also had a setback, allowing three hits, a walk, a hit batsman, and two runs in what proved to be a difficult outing after a long stretch of strong performances. The sequence underscored how competitive the upper levels remain and the need for sustained consistency as the season progresses.
