Welcome to this week’s look at the biggest pitching risers and fallers for fantasy baseball. This list is determined by looking at each player’s current ranking and comparing it to where they were 10 days ago within standard 5×5 league rankings.
In order to keep things fantasy relevant, 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 injury.

Fantasy Baseball Pitching Risers and Fallers
RISERS
Logan Webb (SP, SF) – Webb continues a strong stretch on the mound since returning from injury. He has allowed one earned run or less in each of his last four trips to the mound. Over his last two starts, Webb has managed to average 7.5 innings per game, reducing his ERA to a microscopic 0.00 and his WHIP to 0.52 over this 10-day span.
Webb has improved his changeup, lowering his overall hard-hit percentage to a measly 22.5%. He is also suppressing hard contact to an average exit velocity of 83.4 mph in his recent starts. His overall swinging-strike rate (SwStr%) jumped up from 10.8% to 14.1%,
Sustainability: Highly sustainable. This is vintage Webb displaying elite command and elite ground ball manipulation.
Current Ranking: 145 Prior Ranking: 315 Rostered: 99%
Sandy Alcantara (SP, MIA) – Alcantara is rapidly recapturing his Cy Young form, looking fully recovered over a year removed from elbow surgery. After struggling to a 7.39 ERA in May, Alcantara has pitched to a 2.86 ERA and 0.86 WHIP across 22.0 innings. All three starts were quality starts.
The underlying data validates the rebound. Underscored by a dominant 19:2 K:BB ratio. His sinker velocity has steadily recovered, rising from an early-season 92.4 mph back up to 94.1 mph. Alcantara has also refined his pitch mix, boosting his slider usage by 8% to generate an elite 13.5% SwStr% over this window.
Sustainability: Sustainable. His elite velocity return and excellent command shows he is back to being an ace.
Current Ranking: 140 Prior Ranking: 262 Rostered: 98%
Tanner Bibee (SP, CLE) – Tanner Bibee has become one of the fastest risers. Fresh off a 7-inning, 8-strikeout gem against the Tigers on June 12, Bibee has logged a 2.08 ERA and an exceptional 15:3 K:BB ratio over his last two outings.
Bibee has swapped out his cutter for a heavy dose of his sweeping slider, boosting the sweeper’s usage by 12% over the last 10 days. The adjustments have paid immediate dividends: his SwStr% surged past 15.0%, and his O-Swing% reached 36.2%. He has limited opposing hitters to a 4.1% barrel rate and an 86.8 mph average exit velocity. The 27-year-old righty has now tallied six quality starts in his last seven outings.
Sustainability: Sustainable. All the metrics are pointing in the right direction.
Current Ranking: 223 Prior Ranking: 451 Rostered: 93%
Brandon Young (SP, BAL) – Orioles rookie Brandon Young is generating massive waiver wire traffic after showcasing frontline stuff. Young stifled the Mariners over 7.0 scoreless, 2-hit frames on June 10, bringing his 10-day stat line to a 1.35 ERA and 0.85 WHIP across two quality starts with a sharp 12:3 K:BB ratio. Since May 21, he has pitched 7.2, 7.2, 6.1, and 7.0 innings per game.
His four-seam fastball velocity rose from an average of 93.6 mph to a peak of 95.7 mph against Seattle. By pairing that elevated heat with a highly effective splitter, Young coaxed a 41.2% O-Swing% from hitters. His hard-hit rate dropped to 26.1% over this stretch, forcing opponents into empty swings. He now has four straight quality starts.
Sustainability: Mixed/Moderate. While the raw numbers are undeniably legitimate, sustaining a sub-2.00 ERA will test his workload limits as a rookie.
Current Ranking: 181 Prior Ranking: 305 Rostered: 54%
Dustin May (SP, STL) – May has officially put his two early-season blowups behind him, culminating in a dominant 6-inning, 6-strikeout scoreless gem against the Mets. Over his last 7 turns, the righty has throttled opponents to a 3.43 ERA and a 1.05 WHIP.
May’s explosive sinker velocity is back to sitting at 96.5 mph, and manager Oliver Marmol noted he is landing his entire arsenal for strikes at a much higher clip. Over the last 10 days, his O-Swing% climbed to 34.8%, while keeping his hard-hit rate under 30.0%. May has shown the ability to work deeper into games.
Sustainability: Sustainable. Back to full health and mixing six pitches aggressively, May is reclaiming his front-line fantasy ceiling.
Current Ranking: 220 Prior Ranking: 299 Rostered: 77%
FALLERS
Kyle Bradish (SP, BAL) – Bradish has fallen into a severe funk, possibly tied to ongoing recovery and fatigue following his Tommy John surgery. Over his last two starts, his ERA has inflated to a dismal 6.75 with a 1.62 WHIP, lasting fewer than 5.0 innings per game. His K% in 2025 was 37.3, and this year only 22.6. Bradish has seen his BB% jump from 7.94 to 12.07,
His average four-seam fastball velocity dropped from 95.5 mph to 92.1 mph early in outings, occasionally ticking lower. To compensate, Bradish spiked his hard slider usage by 12% over the last 10 days. Concerns mount that the Orioles will implement a protective shutdown to nurse him through the summer.
Current Ranking: 407 Prior Ranking: 226 Rostered: 96%
Rōki Sasaki (SP, LAD) – After making it on my list last week as one of the biggest risers, Sasaki crashed heavily in his June 12 outing against the Chicago White Sox and is now one of the biggest fallers. He allowed 7 earned runs, 7 hits, and 3 walks in just 4.1 innings, immediately raising red flags across standard formats. While his season narrative indicated a rebound via a newly modified gyro slider and harder splitter, the underlying metrics over the last 10 days show severe regression.
His hard-hit percentage spiked to 46.2% during this period, with an average exit velocity allowed of 92.8 mph. His fastball velocity, which previously sat at 98.4 mph, sat closer to 96.1 mph against Chicago.
Current Ranking: 379 Prior Ranking: 214 Rostered: 93%
Kai-Wei Teng (SP, HOU) – Teng’s brief tenure in the Houston Astros’ starting rotation is rapidly nearing its end, triggering a massive drop in his Fantrax roster percentage. In his June 15 start against the Detroit Tigers, Teng managed just 3.1 innings. Although he struck out 9 batters, opposing batters hit him exceptionally hard. His 10-day ERA sits at an unusable 8.10 with a 1.95 WHIP. Statcast metrics over his last two appearances reveal a catastrophic 14.2% barrel rate and a 48.0% hard-hit clip. Even though his SwStr% remains artificially high at 14.5% because of the single-game strikeout spike, his lack of command inside the zone has destroyed his category value. With ace Hunter Brown returning to the rotation, Teng is probably losing his starting job.
Current Ranking: 320 Prior Ranking: 169 Rostered: 50%
Jack Leiter (SP, TEX) – Leiter’s prominent regression has forced fantasy managers to cut bait over the last 10 days. The 26-year-old righty has now given up exactly five earned runs in back-to-back starts and has amassed just five combined strikeouts during those outings. He has failed to hit the quality start milestone in consecutive turns, yielding an 8.31 ERA and 1.85 WHIP across his last 8.2 frames. Opponents posted a 45.8% hard-hit rate against him this past week, logging an average exit velocity of 93.1 mph. The Rangers are openly discussing a demotion to Triple-A Round Rock or Double-A Frisco to fix his mechanics, rendering him unrosterable in standard leagues.
Current Ranking: 365 Prior Ranking: 224 Rostered: 88%
Jeffrey Springs (SP, ATH) – Springs has completely lost the elite form that he had earlier this season. Consecutive collapses over the last 10 days. Following a 5-run shellacking against Milwaukee, Springs surrendered 6 earned runs on 7 hits over just 4.0 innings against the Colorado Rockies on June 14. His ERA over this 10-day window is a bloated 9.35 with a 1.96 WHIP.
Springs openly admitted to feeling physically sluggish, which manifested as a 1.8 mph velocity drop on his four-seamer (down to 89.4 mph). His premier changeup lost its trademark depth, causing his SwStr% to plummet from 13.8% down to 7.6% over his last two turns. This sudden baseline deterioration could be a sign of arm fatigue or a looming injury designation.
Current Ranking: 376 Prior Ranking: 245 Rostered: 71%
