Los Angeles Dodgers outfield prospect James Tibbs III is still putting up good numbers at Triple-A Oklahoma City, going 7-for-20 (.350) over his last five games, with two doubles, a triple, one steal, and a 3:3 BB:K. The Dodgers' ninth-ranked prospect's slash line now stands at .288/.409/.539, with the strong on-base percentage anchored by a 16.4 percent walk rate. Though the left-handed hitter has 21 home runs and continues to hit for extra bases, he's now gone 24 games without a home run. Still, the strong hitting and keen eye are things that should help get him to the majors this season, although it may be just for a late-season cup of coffee unless one of the regulars were to go down with injury before then. There is fantasy appeal here with the power and the potent lineup he'd be hitting if he got the call, but the 23-year-old isn't on the 40-man roster, and with plenty of other outfield competition for at-bats in the minors, there isn't much need to stash the former first-rounder outside of very deep leagues with multiple NA spots.

The Athletics announced on Tuesday that they placed first baseman Nick Kurtz (thumb) on the 10-day injured list (retroactive to Aug. 1) with a right-thumb sprain and recalled infielder Max Muncy from Triple-A Las Vegas in a corresponding move. The A's decided to put Kurtz on the IL after he visited with a hand specialist on Monday following a few absences over the weekend. The elite left-handed power hitter was diagnosed with a chronic volar plate tear of his MCP joint in his thumb. Kurtz will receive a platelet-rich plasma injection on Tuesday, and there is no timetable for his return. In the two games that Kurtz missed over the weekend against the Detroit Tigers, Jeff McNeil and Jonah Heim filled in for the A's at first base. While on the IL, Kurtz, 23, must be stashed in all fantasy baseball leagues for his power upside in a hitter-friendly home park. The former fourth overall pick from Wake Forest University has hit 21 home runs with 69 RBI in 352 at-bats in 2026 after clubbing 36 homers and driving in 86 in 117 games played as a rookie in 2025.

Boston Red Sox infield prospect Franklin Arias has begun to hit his stride at Triple-A Worcester after going 0-for-8 in his first two games there. Boston's top-ranked prospect has now collected a hit in his last five games, going 7-for-22 (.318) with two doubles, two home runs, and a 4:4 BB:K. The 5-foot-11 Venezuelan earned the promotion to Triple-A after a strong Double-A campaign in which he slashed .318/.407/.587 with 19 home runs and nearly as many walks (37) as strikeouts (46). Now on the doorstep to the majors, fantasy managers will have to take notice as the right-handed hitter has a strong enough hit tool and pop to go with it to make him intriguing for fantasy, however, he's not on the 40-man roster at the moment, and Andruw Monasterio is holding down shortstop sufficiently while Trevor Story is nearing a rehab assignment. Second base is another potential path, but for now, managers can hold off on stashing the 20-year-old until a clearer picture emerges.

Miami Marlins outfield prospect Cam Cannarella has held his own since being promoted to Triple-A in mid-July, now 12-for-43 (.279) with four doubles, a home run, and five steals through his first 11 games with Jacksonville. The Marlins' seventh-ranked prospect is striking out more than normal, 29.4 percent compared to just 13.3 percent at Double-A, but he's also been able to maintain a strong walk rate of 15.7 percent, which is similar to the 15.3 percent rate he posted at Double-A. Expect the strikeout rate to normalize over the remainder of the season, and the Clemson product could make a push for a late-season debut in the majors if all goes well. The 22-year-old hit a sizzling .344 with more walks than strikeouts during his time at Double-A, and with some injured/underperforming assets in the Miami outfield, the 22-year-old could make a case for another promotion. The 6-foot slugger isn't on the 40-man roster yet, and isn't necessarily a stash target at the moment, but he's certainly a name worth monitoring in fantasy leagues for his multi-category potential.
