As we approach Week 18 of the MLB season, finding those diamond-in-the-rough players on the waiver wire can be crucial for fantasy baseball success. This week, hitters like Miguel Vargas of the Chicago White Sox stand out for his multi-position eligibility and run-scoring potential. Meanwhile, Mike Tauchman and Nathan Lukes are proving valuable contributors to their teams, with consistent performances in runs scored and batting average. The home run category sees Tyler O'Neill and Giancarlo Stanton as top pickups, both exhibiting power potential following their recent form. In terms of RBIs, Josh Jung has been a revelation since his call-up, while Mickey Moniak's resurgence with the Rockies adds another dimension. For stolen bases, Chandler Simpson and Colton Cowser are rising stars worth adding. Finally, Jordan Beck and Coby Mayo are making headlines for their batting averages, making them worth consideration in deeper leagues.

Cleveland Guardians closer Emmanuel Clase has been placed on non-disciplinary paid leave amid an investigation regarding sports betting within Major League Baseball. This marks a significant step as Clase is the second pitcher from the Guardians to face this situation, following right-hander Luis Ortiz, who is currently on leave until August 31. The Guardians have stated that they do not expect any further impact on players or personnel from this ongoing probe.

As the trade deadline approaches, significant changes in MLB bullpens are occurring, especially with injuries and potential trades impacting closer roles. With Felix Bautista of the Baltimore Orioles sidelined due to shoulder discomfort, Seranthony Dominguez and Gregory Soto have emerged as primary save options. Meanwhile, the Los Angeles Dodgers are leaning on Alex Vesia and Kirby Yates after Tanner Scott's injury, while the Arizona Diamondbacks are facing turmoil with their closer situation. Similarly, the Miami Marlins' Ronny Henriquez seems secure in his role amidst minor trade talks. The Texas Rangers are experiencing a messy bullpen due to injuries, but Robert Garcia and Jon Gray could see increased save opportunities. Fantasy managers should take note of these volatile situations to scoop potential saves as the trade deadline approaches.
