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.
