Fantasy Baseball Waiver Wire Highlights Emerging MLB Talent

Fantasy baseball analysts spotlight three emerging MLB players as top waiver‑wire targets. Miami Marlins rookie Heriberto Hernández has posted a 93rd‑percentile hard‑hit rate, 86th‑percentile barrel rate and 7 stolen bases in 9 attempts after returning from a brief demotion. Milwaukee Brewers outfielder Andrew Vaughn is expected to receive regular at‑bats following Jake Bauers' toe fracture and has reduced his right‑handed strike‑out rate to 14%. Marlins reliever Michael Petersen is posting a strong ERA and a 29% strike‑out rate in 44.1 innings and could assume closing duties if Pete Fairbanks is traded.

A separate waiver‑wire ranking for Week 18 (2026) lists additional free‑agent options such as Cooper Pratt, Tristan Peters, Clay Holmes, Max Clark and Merrill Kelly. Injuries to Rays starter Shane McClanahan, Yankees infielder Jazz Chisholm Jr., and the pending return of Rangers shortstop Corey Seager are also noted, while the Tigers consider trading left‑hander Tarik Skubal and the Cardinals have promoted pitching prospect Quinn Mathews for his MLB debut.
