Marty Tallman's hitter fantasy baseball prospects to stash for Week 14 (2026). His MLB prospects to pick up and stash on your bench and N/A spots in redraft leagues.
We’re now entering Week 14 of the 2026 MLB season, which makes it a good time to start stashing high-upside prospects who could help down the stretch in the second half.
Most of these names are best suited for deeper AL- or NL-only leagues, but a few could work their way into mixed-league value if things break right. All players are rostered in fewer than 40% of Yahoo! leagues.
As the season goes on, keep an eye on injuries and underperforming regulars around the league because those are often the openings that turn a stash into a usable fantasy piece. Let’s get into it.

Leo De Vries, SS, Athletics
Leo De Vries is already the No. 2 prospect in baseball, and even though he's still in Double-A, he's the type of player worth stashing now in head-to-head formats with fantasy playoffs.
The Athletics acquired the 19-year-old switch-hitting shortstop in the blockbuster deal that sent Mason Miller to San Diego, and his stock has only continued to rise since.
Through 64 games at Double-A, De Vries is slashing .273/.367/.418 with nine home runs, nine doubles, and 22 stolen bases.
When De Vries eventually gets the call, which is likely to be in late August or early September, he should play every day with Jacob Wilson at the keystone.

So far this season, A's shortstops have been underwhelming to say the least. They have combined for just an 87 wRC+, with Wilson, Darell Hernaiz, and Alika Williams struggling to provide consistent offensive production.
If the Athletics remain in the playoff race, De Vries could force the organization's hand sooner rather than later. As of Thursday, the A's sit just 1 1/2 games behind the Seattle Mariners in the AL West, keeping them firmly in the postseason conversation.
Another factor working in De Vries' favor is his eventual home park. The Athletics are playing in one of the most hitter-friendly parks in baseball, as Sutter Health Park carries a 110 park factor that ranks second only to Coors Field.
When he arrives, he'll be stepping into a hitters' paradise. Overall, he will be serviceable in all leagues and has the upside to be a five-category contributor right away.
Charlie Condon, 1B/OF, Colorado Rockies
The Colorado Rockies have already called up TJ Rumfield, Cole Carrigg, and Kyle Karros this year, and they probably aren’t done. Charlie Condon is the Rockies' No. 1 prospect, and it feels like only a matter of time before he’s in the big leagues.
At Triple-A this season, he’s slashing .270/.404/.524 with 14 home runs, five stolen bases, a 22.8% strikeout rate, and a 15.1% walk rate.
In addition, Condon is chasing just 18.4% of pitches, which ranks in the 92nd percentile. Overall, his advanced approach stands out as much as his raw power, which Fangraphs rates as a 70.

Under the hood, Condon owns a 9.7% barrel rate and has reached a max exit velocity of 112.6 mph. Which means he's already hit the ball harder than names like Samuel Basallo, Riley Greene, and Rafael Devers, this season.
While he’s primarily viewed as a first baseman long-term, he’s not a zero on the bases. His sprint speed ranks in the 85th percentile, so a handful of steals isn’t out of the question.
Add in the obvious boost from Coors Field, and the fantasy upside becomes even more appealing. With the Rockies still stuck in a long-term rebuild, there’s little reason to keep a bat like Condon in Triple-A much longer.
A late-July or early-August promotion feels like the most likely outcome, making him a must-stash in 15-team mixed leagues thanks to his combination of power and plate discipline.
Zac Veen, OF, Colorado Rockies
Another Rockies prospect worth stashing in deep leagues is former first-round pick Zac Veen.
The 24-year-old outfielder received his first taste of the majors last season, but the results were rough, as he slashed .118/.189/.235 with one home run and a 37.8% strikeout rate over 37 plate appearances.
It was a tiny sample, but opposing pitchers quickly exposed his biggest weakness, attacking him with breaking balls, especially sliders.
Veen has continued to struggle against sliders at Triple-A this season, posting just a .196 expected batting average (xBA) against the pitch. However, the encouraging news is that he's handled fastballs well and has done significant damage against sinkers.
Through 296 plate appearances at Triple-A, Veen is slashing .329/.416/.573 with 12 home runs, 14 stolen bases, and a 136 wRC+. The production has put him firmly back on the fantasy radar, and the Rockies' roster situation could open the door sooner rather than later.

Colorado's current outfield features Carrigg, Jake McCarthy, and Mickey Moniak, while Troy Johnston has handled much of the designated hitter role. That picture could change after the trade deadline.
Moniak, who is on a one-year deal, is widely viewed as the most likely outfielder to be moved, and if he is, that would create an opportunity for Veen. Over a full season, Veen has the upside to produce 15-20 home runs with double-digit stolen bases, and Coors Field only raises that ceiling.
He should be stashed in deeper NL-only leagues and is worth a look in 15-team mixed leagues when he does get called up again.
James Tibbs III, 1B/OF, Los Angeles Dodgers
To no one's surprise, the Los Angeles Dodgers are once again loaded with talent from top to bottom. Their major league roster is stacked, and the pipeline isn't slowing down anytime soon.
One of the latest names forcing his way into the conversation is James Tibbs III. The Dodgers' No. 9 prospect has been putting on a show at Triple-A. Through 73 games, Tibbs is slashing .291/.417/.579 with 20 home runs and three stolen bases.

His 26.3% strikeout rate is a little higher than you'd like, but he more than makes up for it with an excellent 17.1% walk rate. More importantly, the quality of contact has been outstanding.
He's barreling the ball 18.4% of the time and owns a .291 ISO, a clear sign that the power is very real. He's been one of the most dangerous hitters in the Pacific Coast League.
The only thing standing between Tibbs and the majors is opportunity. The Dodgers don't have many lineup spots to hand out.
If healthy, Kyle Tucker and Andy Pages aren't going anywhere, and Teoscar Hernandez is expected back from his hamstring injury within the next week or so after beginning a rehab assignment.
Still, there are a few cracks in the door. Ryan Ward has managed just a 95 wRC+ over 59 plate appearances while slashing .204/.271/.444, while his 28.8% strikeout rate hasn't helped his case to stay up either.
Hernandez and Tucker have also battled injuries this season, and with October being the Dodgers' priority, regular rest days for their veteran outfielders are almost inevitable down the stretch.
It wouldn't take much for Tibbs to get his chance. Another injury or even an extended slump by Ward could be enough to earn him a promotion, and once he's in Los Angeles, it's hard to ignore the fantasy upside of any hitter getting regular at-bats in that lineup.
For now, Tibbs is worth stashing in NL-only formats. When he does get the call, and even if he begins on the strong side of a platoon, he has enough upside to be rostered in 15-team mixed leagues.
George Lombard Jr., SS, New York Yankees
Even though George Lombard Jr. is currently on the 7-day injured list with sprained fingers on his left hand, he still deserves to be stashed in deeper AL-only leagues.
The 21-year-old is the Yankees’ No. 1 prospect and widely viewed as their shortstop of the future. Right now, he’s blocked at the big-league level by Jose Caballero and Anthony Volpe.
Caballero brings defensive versatility and can handle multiple infield and outfield spots, while Volpe has been inconsistent at the plate and hasn’t fully locked down the job long-term.
That said, neither situation is likely to hold Lombard down for too long if he keeps progressing. At Triple-A, Lombard has posted a .387 on-base percentage with eight home runs and 12 stolen bases, along with a 21.3% strikeout rate and a strong 16.4% walk rate.
The main question is how quickly the bat translates. He’s had trouble with fastballs at times, which could lead to some early struggles once he reaches the majors. On the positive side, the tools are all there.
He has plenty of bat speed, a patient approach, and developing power that’s starting to show up more consistently as he matures. Here are his Triple-A Statcast numbers:
Although his sprint speed doesn't jump off the page, Lombard is also capable of swiping bags. Plus, his defense should also help him earn plenty of playing time once he arrives.
Five Other Prospects to Consider Stashing
- Joshua Baez, OF, St. Louis Cardinals
- Kaelen Culpepper, SS, Minnesota Twins
- Hector Rodriguez OF, Cincinnati Reds
- Seaver King, SS, Washington Nationals
- Walker Jenkins, OF, Minnesota Twins
