Navigating the ups and downs of a long season requires quick decision-making and a sharp eye for underlying trends. By analyzing recent FanGraphs data over the last seven days alongside advanced Statcast (Baseball Savant) metrics, we can separate genuine skill shifts from temporary good fortune. That analysis helps you optimize your fantasy baseball waiver wire activity and exploit high-yield windows on the fantasy baseball trade market. This week's fantasy baseball stock watch highlights the players moving the needle, the ideal trade targets, and schedule advantages to exploit in the coming days. 

Fantasy Baseball Stock Watch Risers This Week

Bryce Eldridge, 1B/DH, San Francisco Giants

Initially a part-time player upon his call-up, Eldridge has locked down a regular role following injuries to Heliot Ramos and Harrison Bader. Over his last seven games, he is slashing a mammoth .522/.571/.870 with one home run, four RBI, and nine runs scored. Most impressively, his strikeout rate sat under 18-percent during this span. Statcast data supports this breakout, showing an elite 52.3-percent hard-hit rate and a minuscule 6.2-percent swinging-strike rate over the past week. His improved contact skills make him a must-start asset while the Giants' outfield heals.

Jake Mangum, OF, Pittsburgh Pirates

While Mangum remains a part-time player, he maximized his 19 plate appearances over the last six games by swiping four stolen bases. Stolen bases are the fastest category to move in fantasy standings, making dedicated speed assets incredibly valuable. Pairing that speed with a staggering .526 OBP over the past week makes him a highly efficient option. Statcast reveals an excellent 92nd-percentile sprint speed that fuels his baserunning floor. He is a premier short-term specialist for managers needing an immediate injection of speed. For more speed, check out my weekly Stolen Base Report, which comes out every Saturday.

Spencer Steer, OF, Cincinnati Reds

With Elly De La Cruz on the 10-day IL and Eugenio Suarez slumping, Steer has reclaimed regular playing time and capitalized immediately. Over his last six games, he is batting .400 with two home runs, two RBI, six runs scored, and a .500 OBP. Statcast metrics validate this surge, highlighting a 14.3-percent barrel rate and a tight 11.5-percent chase rate over the last seven days. Steer is locking in his plate discipline exactly when the Reds need him to anchor the middle of the lineup.

Dustin May, SP, St. Louis Cardinals

May has done incredible work to lower his early-April 15.95 ERA to under 5.00 here in early June. While he still experiences occasional bumps in the road, May has surrendered three earned runs or fewer in nine of his last 10 starts. Over his last three outings, he posted an exceptional 25:4 K:BB ratio across 18 innings. Statcast confirms his sinker velocity is back up to a 96.8 mph average, while his raw spin rates on the breaking ball remain elite. He may not be a true fantasy ace, but he provides incredibly solid, reliable middle-of-the-rotation production.

 

 

 

Fantasy Baseball Stock Watch Fallers This Week

Eugenio Suarez, 3B/DH, Cincinnati Reds

Suarez’s deep slump is directly tied to Spencer Steer's playing time boost, putting his everyday role in serious jeopardy. His horrific 38-percent strikeout rate over the past week highlights a major issue with making contact. While his raw power means a few more home runs will come, he has become an active liability for Cincinnati. With Noelvi Marte waiting in the wings and receiving promotions, the Reds might be ready to move on from Suarez permanently. FanGraphs shows his zone-contact percentage has plummeted to a career-low 71.2-percent over the last seven days.

Andy Pages, OF, Los Angeles Dodgers

We are not giving up on Pages long-term, but fantasy managers, especially those in head-to-head leagues, are running out of patience. Pages is batting just .167 with no home runs and a single RBI over his last seven games. He is prone to these prolonged slumps, which severely penalize managers in weekly formats. Statcast reveals his whiff rate on high fastballs has spiked to 34-percent this week. He remains an excellent buy-low target for patient managers, particularly in rotisserie leagues where his season-long upside can crystallize.

Connor Prielipp, SP, Minnesota Twins

Following a stellar debut, Prielipp is experiencing standard rookie growing pains as major league hitters adapt to his look. He must counter by altering his pitch mix and adjusting his spin and velocity. Over his last three starts, he allowed 15 earned runs across 14.1 innings, saddled with a weak 13:8 K:BB ratio. Statcast data shows his slider has lost nearly two inches of vertical drop compared to April, allowing hitters to lay off the pitch down in the zone. Bench him until he shows signs of recalibrating his pitch mix.

Lucas Erceg, RP, Kansas City Royals

After surrendering nine earned runs over his last four appearances (spanning just 3 innings), Erceg appears to have lost his grip on the closer role. According to our Closer Grid, David Lynch IV and Alex Lange are earning high-leverage opportunities, though the Royals are not creating many save situations lately. FanGraphs points to Erceg's ballooning 14.5-percent walk rate over the last week as the primary culprit for his implosion. He will need a long stretch of clean, scoreless appearances to earn back high-leverage trust.

Best Fantasy Baseball Buy Low Candidates

Chandler Simpson, OF, Tampa Bay Rays

Simpson is mired in a deep slump, batting .130 with a .167 OBP and zero stolen bases over the past week. In fact, he hasn't stolen a base since May 2, leaving fantasy managers incredibly frustrated. However, many managers are unaware of how much an underlying leg injury hindered his lower-half explosion, even though he avoided an IL stint. He also endured a freak accident where his batting helmet flew off and struck him directly in the mouth. Despite the bad luck, manager Kevin Cash put him right back in the leadoff spot. This vote of confidence signals an impending turnaround, making him a prime target before the speed returns.

Austin Riley, 3B, Atlanta Braves

Riley has performed well below his draft pedigree all season long, driving his current managers to absolute desperation. Many are willing to trade him for pennies on the dollar before considering an outright drop. You should aggressively target him solely for his elite power upside. Even if his baseline has shifted down, trading for him requires minimal asset risk right now. If Riley experiences a hot streak alongside a rising Braves offense, you will secure an elite power bat for a fraction of his actual value.

 

 

 

Fantasy Baseball Sell High Candidates

J.P. Crawford, SS, Seattle Mariners

Crawford is riding a hot streak, batting .318 with three home runs, four RBI, and five runs scored over his last six games. However, this power surge is a complete aberration from his established baseline. FanGraphs shows a near-30-percent strikeout rate over the past week, which confirms his high batting average is unsustainable. His Statcast expected batting average (xBA) over this stretch sits at a modest .224, indicating heavy good fortune on balls in play. Sell him immediately to a manager desperate for middle-infield help.

Miguel Vargas, 3B, Chicago White Sox

We advised selling high on Vargas last week, and another three home runs with 10 RBI over the past seven days only strengthens that stance. This torrid pace cannot continue over the summer months. The White Sox will likely run out of steam and shop him ahead of the trade deadline. If Vargas is dealt to a contender, he will almost certainly revert to a part-time utility role, obliterating his everyday fantasy value. Cash in on this peak production before his playing time dries up.

Fantasy Baseball Players to Watch Next Week

Athletics Hitters

The Athletics launch a massive 13-game homestand next week at Sutter Health Park in Sacramento, an incredibly hitter-friendly environment. They host the Brewers, Rockies, Pirates, and Angels. Fantasy managers should aggressively stream Oakland hitters or target opposing bats visiting this park, as the environment significantly inflates run production and home run factors.

Arizona Diamondbacks Hitters

Arizona opens next week in Miami against a heavily compromised Marlins pitching staff, missing everyone outside of Max Meyer. From there, they travel to Cincinnati to play at Great American Ball Park, one of the premier hitting venues in baseball. They are projected to face left-handers Andrew Abbott and Nick Lodolo. This is a massive advantage, as Arizona carries a stellar .342 wOBA (second-highest in MLB) and a robust .172 ISO against left-handed pitching this year.

Potential Stolen Base Surge

Target matchup-based speed options over the next seven days. Detroit and St. Louis square off against the Twins, whose catcher, Victor Caratini, remains one of the least efficient backstops at throwing out base-runners. Additionally, look to the Red Sox and Angels rosters as they face the Tampa Bay Rays. Rays catchers have permitted a combined 17-percent caught-stealing rate on a massive 59 attempts this season, offering a green light for opposing runners.
