The Yankees are planning on calling up first baseman Juan Miranda from the minor leagues.DETROIT—In hopes of adding some pop to their depleted ranks, the Yankees will call up Juan Miranda today, a person with knowledge of the situation confirmed. The move was first reported by the New York Post.
It makes sense with Nick Johnson’s career-ending injury. Miranda had an average projection of around .256/.330/.428, which is a wOBA of around .331. That’s essentially league average, which is replacement level for a DH. However, if we look at him as the left-handed half of a DH platoon, he’d have a wOBA of .311 vs. LHP and a wOBA of .338 vs. RHP using regressed platoon splits. If we add that to Thames’s estimated .342 wOBA vs. LHP, it’s a wOBA of around .339 for the platoon. That’s not close to Nick Johnson’s revised projected wOBA of .372, but it’s a hair above replacement level. For 400 PAs, the difference between Johnson and that platoon would be around 11 runs, and the difference between the platoon and a replacement level DH would be about 3 runs.
So it’s not great, but it’s not likely to be the difference between making the postseason or not.
