12:30pm: The Diamondbacks are also showing some interest, Morosi tweets. It’s good news for Castellanos to have National League teams involved, though it’s still not clear which if any would be interested in a lengthy commitment.
Castellanos is one of the many Scott Boras-repped players populating the upper reaches of the open market. He joins Marcell Ozuna among the top-available outfield options.
While it’s a bit worrisome to imagine Castellanos patrolling the spacious Oracle Park outfield, the club is pulling in the fences this winter. And as Morosi notes, it’s also possible that the youthful slugger could at some point step back into the infield. (He never managed to stick at third base previously but could presumably be expected to play a palatable first base.)
Castellanos is an exceptionally difficult free agent to prognosticate. We ultimately settled on a prediction of four years and $58MM, but batted around quite a few alternative concepts. Castellanos is an accomplished but hardly all-world hitter who has shown some improvements in the field but remains a bat-first player. Involvement of the Giants in his market would assuredly help, as the level of demand has constituted a major element of uncertainty in the earning outlook.
