8. Brandon Belt
Age has done nothing to slow Brandon Belt down. The two-time World Series Champ continued to flash his power with the Toronto Blues Jays in 2023, but remains unsigned through the first few weeks of Spring Training. Never a standout on defense, Belt still has plenty to offer at the dish.
Most of Belt's appearances last year came in the DH role, making some of his metrics stand out even more. In 2023, the former Giant put together a 2.0 WAR despite hitting -0.9 on defense. Predictably, that correlates with elite offensive production, with the 36-year-old accumulating his best OPS since 2020.
Of course, age will scare some teams off, but Belt's underlying metrics support that his offensive production is sustainable. He ranked in the 91st percentile or better in sweet spot contact, barrel rate, and walk percentage. In today's modern age of baseball, that still counts for a lot.
