Mark Vientos

At 26 years old, Vientos enters 2026 as a power-dependent first baseman coming off a disappointing start to the season marked by a .209 batting average through 230 at-bats. His home run pace has slowed considerably from 2025 when he clubbed 17 homers and drove in 61 runs, suggesting he's struggling to make consistent contact and capitalize on his power stroke. Fantasy managers should view him as a high-variance gamble whose upside in home runs and RBIs remains intact, but his batting average represents a significant drag on overall production given his current performance. A prolonged slump could relegate him to a bench role, but a return to his 2025 form would make him a valuable power source at the position.
