Seattle Mariners ยท Third Base
At 28 years old, Rivas enters 2026 as a career minor leaguer fighting for consistent MLB opportunities after a disappointing start to the season (.131 average through 99 at-bats). His 2025 campaign showed modest promise with a .244 batting average and 6 stolen bases across 90 at-bats, suggesting he possesses some speed and contact ability when given regular playing time, though power remains a significant weakness with just 2 home runs. For fantasy purposes, Rivas profiles as a deep-league flyer who offers minimal upside in batting average and home runs but could contribute modest steals if he secures an everyday role at the hot corner. The real risk here is whether he can reverse his 2026 skid and prove his 2025 performance was the baseline; without a dramatic turnaround, he's likely roster filler at best in most formats.
