When determining who to add to this list of risers and fallers, I look at a standard 5×5 league ranking. The list is based on where the player ranks today, using their production from the start of the season. We then compare this rank to their rank from ten days ago.
To ensure this list applies to most fantasy managers, either the current ranking or the prior ranking must be in the top 300. I have also tried to avoid any players who have risen or fallen because of a stay on the IL.

Fantasy Baseball Risers and Fallers
Also, check out our top Pitching Risers and Fallers.
Hitting Risers
Zack Gelof (2B, ATH) – Gelof’s fantasy profile has turned a corner over the last 10 days. His 20-game hitting streak rescued his early-season batting average. The second baseman is suddenly making far more contact. Gelof is flashing a .286 average and .835 OPS with 10 home runs and 8 steals on the year.
He has dramatically improved hi approach within the strike zone. Gelof’s Z-Contact% has risen significantly over this stretch. His strikeout percentage, which was 34% and 45% in 2024 and 2025, is now down to 25.5%.
Sustainability: Sustainable if the improved strikeout rate is real.
Current Rank: 234      Previous Rank: 432 Rostered: 69%
Tyler Soderstrom (C/OF, ATH) – Soderstrom is turning potential into production. He has launched five home runs over his last 12 games, hitting .317 with 13 RBIs in June. His overall season total is up to 12 long balls and an .814 OPS.
His sudden standard-league value comes down to pure contact. Over the last 10 days, Soderstrom’s hard-hit rate (95+ mph exit velocity) surged to an elite 51%, and his average exit velocity climbed past 93 mph. He is consistently squaring up major league pitching, punishing mistakes rather than fouling them off.
Sustainability: Maybe. He has high strikeout tendencies, but the power is here to stay.
Current Rank: 160      Previous Rank: 341 Rostered: 99%
Matt Chapman (3B, SFG) – Chapman has been on fire in June, posting a staggering .415/.519/.902 slash line with 6 home runs and 20 RBIs through his first 13 games of the month. He has single-handedly carried fantasy teams through this recent 10-day block.
Chapman has walked nearly as often as he has struck out over this run. This has lowered his overall chase rate by 8 percentage points. By refusing to swing at breaking balls out of the zone, he is getting ahead in counts and waiting out premium fastballs.
Sustainability: NOT. This is a classic Chapman hot streak. His historical profile shows deep peaks and valleys. Enjoy the elite production, but prepare for the inevitable cooling-off period.
Current Rank: 193      Previous Rank: 356    Rostered: 92%
Willi Castro (2B/3B/SS/OF, COL) – Since signing with Colorado, Castro has provided a highly effective, multi-positional baseline. He recently went 7-for-13 with two homers and nine RBIs over a three-game stretch, pushing his season average to .282 with 5 home runs and 5 steals.
Castro’s spike is a product of increasing his line drives. His ground ball-to-fly ball ratio shifted heavily over the last 10 days, as he cut his ground ball rate down by 10 percentage points. He is hitting line drives into the gaps at a 28% clip, letting his speed create extra-base hits.
Sustainability: Probable – Castro’s underlying Statcast contact metrics aren’t mind-blowing, but hitting line drives in the thin mountain air makes him an excellent, multi-positional asset to ride all summer.
Current Rank: 287      Previous Rank: 445   Rostered: 56%
Kody Clemens (1B, 2B, OF, MIN) – Clemens has forced his way into regular playing time in Minnesota with a massive June surge. Over the last 10 days, his standard-league viability has skyrocketed. His line for the season is now .251/.318/.493 with 11 home runs and 6 stolen bases across 215 at-bats.
Clemens has completely cut down on pop-ups, dropping his ground ball rate by nearly 9 percentage points to optimize a lethal 26% line-drive rate. His hard-hit rate on inside pitches has jumped to 46% during this 10-day window, allowing his pull-side power to play up significantly in standard formats.
Sustainability: Mixed. This is a hot streak with structural improvements.
Current Rank: 235      Previous Rank: 387    Rostered: 62%
Hitting Fallers
Willy Adames (SS, SFG) – Over his last 24 at-bats, his triple-slash line dropped to 167/.222/.250 with just one RBI. Behind this slide is an aggressive approach that is not yielding results. Adames’ chase rate (O-Swing%) spiked from 28.5% to 37.1% over the last 10 days, leading to a bloated 33.3% strikeout rate. His zone contact rate (Z-Contact%) has plummeted by 9 percentage points. He now has only three hits in his last 36 at-bats.
Current Rank: 198      Previous Rank: 152 Rostered: 95%
Nico Hoerner (2B, CHC) – Hoerner’s fantasy appeal lies in his batting average and elite speed, but both have vanished over the last 10 days. The slumping Hoerner is batting just .200 with zero home runs and two stolen base attempts in his last 35 plate appearances. Known for a line-drive approach, his groundball-to-flyball ratio dramatically skewed toward the turf, rising from 1.2 to an ugly 2.5. Hitting the ball on the ground 58% of the time has completely neutralized his speed, as his average exit velocity similarly slipped from 88.5 mph down to 84.1 mph.
Current Rank: 172      Previous Rank: 127   Rostered: 99%
Austin Riley (3B, ATL) – Riley’s mid-June slide is a major concern for managers counting on power. Over the last 10 days, he managed a  .182 slugging percentage with no home runs and only two RBIs. Statcast paints a not so wonderful picture of his contact quality: Riley’s hard-hit percentage (95+ mph exit velocity) collapsed from a season average of 46.2% to a weak 24.1% over this span. He is consistently rolling over the ball, as his average launch angle cratered by 11 degrees.
Current Rank: 225      Previous Rank: 183   Rostered: 98%
Xander Bogaerts (2B, SDP) – Bogaerts’ slow decline has reached a tipping point over the last week and a half, with his batting average falling to .226. Bogaerts’ walk-to-strikeout (BB/K) ratio, usually a pillar of his fantasy floor, shrank to  0.15 over the stretch, logging eight strikeouts against a single walk. With a 27.3% strikeout rate, he is having one of the worst stretches of his career.
Current Rank: 203      Previous Rank: 179 Rostered: 87%
Ildemaro Vargas (INF, ARI) – After an amazing start to the 2026 season, Vargas has become one of the league’s biggest fallers. His batting average has tumbled 85 points over his last 28 plate appearances, yielding a weak .143 OBP. Pitchers are feeding him soft, away, breaking balls, causing his overall zone contact rate to plummet by 12 percentage points. Vargas’ line-drive percentage dropped from 26% to 11% during this 10-day window. Vargas is 1-for-18 in June games
Current Rank: 243      Previous Rank: 189 Rostered: 65%
