Midseason Call‑ups: 12 Players Making an Impact
The latest wave of minor‑league call‑ups has turned heads across the baseball landscape, with a dozen players earning their first taste of the majors in the past two weeks. While some arrivals are fleeting, others are staking claims that could reshape fantasy lineups and future roster decisions.
Brett Bateman, the 36th‑ranked prospect in the Blue Jays system, has started every game since his August 7 recall, showcasing a disciplined approach that includes a double‑digit walk rate and a surprisingly high BABIP. Though he lacks power, his speed has been on full display, as he has already stolen 20 bases while being caught only three times, making him a coveted asset in OBP‑heavy formats and for those chasing steals.
Charles McAdoo, the 32nd‑ranked Blue Jays prospect, seized the opportunity when Vladimir Guerrero Jr. landed on the injured list, taking over as the team’s starting first baseman. His Triple‑A stint featured solid walk and strikeout rates, a sub‑10% swing‑and‑miss percentage, and a modest uptick in power metrics that suggest he could provide steady production at the keystone of the lineup.
Debut Highlights
Joshua Báez arrived in mid‑August after a series of roster moves and immediately made noise with a historic debut that featured three home runs in his first game, followed by a 0‑for‑5 slump. His elite power profile — highlighted by a 19.7% barrel rate and 21 steals — has earned him a must‑add status in virtually every fantasy league, especially in shallow formats where a single breakout performance can swing the standings.
Turner Hill, acquired in a trade for Heliot Ramos, has settled into a starting left‑field role and is posting a .353 batting average fueled by a .368 BABIP. His plate discipline is evident in a low strikeout rate, though his power numbers remain modest, painting a picture of a contact‑oriented hitter who could benefit from a more favorable hitting environment.
Angel Genao, recalled on August 5, has rotated between second and third base while maintaining a double‑digit walk rate and a mid‑teens strikeout rate. His power output shows flashes — a 19.6% HR/FB rate and a 5.9% barrel percentage — but the inconsistency suggests he may need more regular at‑bats to prove his upside.
Brock Rodden, brought up to fill a shortstop vacancy, boasts a high HR/FB rate but his Statcast metrics tell a different story; his expected weighted on‑base average (.289) lags far behind his actual .367 mark, indicating that his current MLB bat may lack the punch his minor‑league numbers hinted at.
Abimelec Ortiz, who burst onto the scene on August 4, has already hit five home runs despite being part of a platoon, and his power metrics have improved markedly from the previous season. However, his recent BABIP figures are unremarkable and he does not contribute on the bases, leaving his long‑term upside dependent on sustained power production.
Zac Veen, posting a 142 wRC+ at Triple‑A, combines power and speed, but his wOBA has been inflated by the hitter‑friendly environment of his previous venue. He is a must‑start during Coors Field homestands, yet his platooning role could limit his weekly league value.
Power and Speed Dynamics
Connor Norby has claimed the majority of second‑base plate appearances since his August 10 recall, and while his minor‑league HR/FB rates were strong, his HardHit% and maximum exit velocity have been underwhelming, suggesting a tenuous power profile. The 20‑year‑old has already added eight steals, positioning him as a potential power‑speed hybrid in deeper fantasy formats.
Brett Callahan has started in left field in both games since his recall, delivering 13 minor‑league homers and 29 steals, but his Triple‑A xwOBA of .309 hints at a power profile that may not translate consistently at the big‑league level. He is likely to remain a platoon piece against left‑handed pitchers, which could cap his overall value.
Kaelen Culpepper, ranked 35th overall, posted a career‑best walk rate and kept his strikeout percentage under 20% at Triple‑A, while his ISO surged past .200. Although his barrel percentage remains low, his 17 steals illustrate a well‑rounded skill set that could make him a versatile contributor if his power translates.
George Lombard Jr., promoted to a starting role after his August 4 call‑up, has walked an elite 16.8% of the time and posted a .341 BABIP, while his power metrics were solid enough to suggest future upside despite a modest barrel rate. He has stolen 14 bases but was caught nine times, leaving his running game as a developing, yet potentially valuable, component.
Overall, the influx of fresh talent offers a blend of high‑risk, high‑reward options for fantasy managers, with each player’s unique mix of plate discipline, speed, and power shaping their short‑term impact and long‑term outlook.
