As Week 16 of the MLB season begins, five under-50% rostered hitters are highlighted for fantasy baseball: Romy González (BOS) is excelling against lefties, Chandler Simpson (TB) offers elite speed and a high average, Austin Hays (CIN) is a reliable outfielder, Mickey Moniak (COL) shows power with a strong batting average, and Victor Caratini (HOU) is a top catcher option with recent hot streaks.
