Corey Seager wears the UA Yard Low cleat, both for pre-game and in-game. WPW saw him wear his TPU versions (plastic) for pre-game, and then switch to metals for game time. Seager does this to save his legs since plastics are a little more comfortable.
The Yard is an often re-designed line of cleats, and Seager has the 2015 version. At the link, you’ll find several versions, with Seager’s being the one pictured. You won’t find his colorways, but there are plenty available.
