Fantasy Baseball 2026: Players to Stash Right Now – Watch List, Prospects & IL Stashes

Early May marks a clear pivot point in fantasy baseball. The first month is in the books. Managers now shift from chasing last week's hot streaks to building for June through September. Identifying fantasy baseball players to stash in 2026 comes down to spotting talent whose current roster percentages do not match their true value.

The casual owners in your league do the weekly stash routine. Two start pitchers. Hitters who swatted 3 HR last week. Smart owners stash. They target injured arms nearing return, prospects raking in Triple-A and watch-list veterans whose Statcast profiles scream regression.

Below are players who are under 40 percent rostered in most leagues. They offer real second-half separation potential in most fantasy baseball formats.

Top IL Stashes – High-Upside Returns Nearing Activation

Players Worth a Bench Spot for Immediate Second-Half Impact

Jared Jones, SP, Pirates - Jared Jones tops any IL stashes in the fantasy baseball 2026 conversation. In 2024, he flashed skills that reminded many of teammate Paul Skenes, with a 97.4 mph fastball velocity which produced a 9.76 K/9 figure. Overall he owned a 4.14 ERA (3.78 expected fielding independent pitching figure, xFIP), but was uneven, giving up earned runs in every start from June on.

The Pirates right-hander suffered a UCL injury in spring training last year and hit the 60-day IL after the internal brace surgery last spring. But he's returned to action in rehab. His first minor-league rehab start on April 28? Three perfect innings. Five strikeouts. Fastball touched 101.1 mph. Jones is due to return late May or early June. Expect 140 strikeouts over 120 innings post-return. Stash him in any league with an open IL spot. Check the fantasy baseball waiver wire for the latest updates.

Jones turns a bench spot into rotation depth by Memorial Day.

Prospect Call-Ups to Stash Right Now

Minor-League Standouts Ready for Major-League Impact

Max Clark, OF, Tigers - Max Clark is getting his AAA seasoning before an inevitable call-up in the coming weeks. He continues to be a patient hitter, walking 11.3 percent and striking out only 15.3 percent, consistent with his previous experience in lower levels of the minors. His power has not yet met previous standards, with just 1 HR in 29 games. But he's collected 11 RBI, 18 runs and 9 steals, while hitting .276 with an OBP of .353.

His plus speed and contact skills project to 20/20 potential. Five-category upside makes him a stash in deeper leagues and if you will need summer stolen bases. Dynasty owners may not have the option, as they should have grabbed him yesterday.

Bryce Eldridge, 1B/DH, Giants - Eldridge, a more traditional straight power hitter than Clark rounds out the prospect duo. The Giants first baseman made his season debut with the Giants this week, going 0-for-3 at DH. He showed good power in the spring, after hitting 25 HR, 84 RBI in 102 minor league contests last year. He's about a .260 hitter, and about an average OBP play, but his power is obvious.

Since he's been called up, you'll have to rush to the waiver wire faster than a week ago, but you can stash him on the bench but he will have an almost immediate impact most likely.

Watch-List Breakouts – Hidden Stash Candidates

Players Showing Elite Underlying Metrics but Still Available

Ke'Bryan Hayes, 3B, Reds - Ke'Bryan Hayes owns a significant surface-to-underlying gap that could reward a savvy fantasy baseball owner. When you pick up a player hitting .126 with a .191 OBP, you're clearly stashing him.

Hayes has suffered from brutal luck. His average exit velocity sits 91.8 mph. His hard-hit rate tops 41 percent. The barrel rate is 12.5 percent. Expected wOBA is .315, far exceeding that .191 OBP. With just 2 HR and 3 RBI (and no steals), it won't be a race to pick him up, but he can contribute 10-12 steals and a handful more HR in deeper leagues, or just during a hot streak.

Landen Roupp, SP, Giants - Landen Roupp fits the same mold on the mound. He has struck out 6 or 7 hitters in 5 of his 6 starts. He had a rough outing this week, which will suppress any interest in him but he is 19th among starters in WAR, between José Soriano and Jacob Misiorowski, two pretty good arms. He is a good groundball pitcher who has not allowed a single barrel yet this year. He relies on above average fastball and curveballs, but more so on location. So there might be peaks and valleys, but he is worth owning.

Stash Strategy & Priority List for May 2026

How Advanced Managers Should Attack the Wire Right Now

Prioritize like this. One: Jared Jones if you need strikeouts. Two: Max Clark in formats that value speed. Three: Ke'Bryan Hayes everywhere third base lacks depth. Four: Bryce Eldridge for power-only upside. Five: Landen Roupp if pitching ratios lag.

May 2026 sets the second-half table. Casual managers chase. Advanced ones stash Jones, Hayes, Clark, Eldridge and Roupp. These five turn waiver wire fliers into category dominators. Claim them before the market wakes up.
