According to what Terry Collins just told Mike Francesa on WFAN, moving Daniel Murphy to first base isn’t just to see Jordany Valdespin at second. There will be a platoon, with Justin Turner facing lefties, Valdespin righties.
The only issue with this is Turner, while right-handed, is a significantly better hitter against righties, a career .705 OPS mark against righties, just .638 against lefties. You have to give him this: he’s a better hitter against lefties than Valdespin. But this is playing him regularly without utilizing his superior skill (well, relatively speaking).
Here’s an out-of-the-box idea: play Josh Satin at first base against lefties, Daniel Murphy at second. Murphy is better against righties, but his .686 career OPS against lefties still tops Turner or Valdespin. Against righties, play Murphy at first, if you must, and Valdespin at second. Or Turner. Really, either way. Neither one is particularly excellent against them, career, and bring below-average fielding to go with it.
Or better yet: Murphy stays at second. Lucas Duda, out fielding grounders this afternoon at first base, moves to his natural position. Acknowledge that merely standing Lucas Duda in left field is not the same thing as having a left fielder, see whether Duda and Murphy can be your right side of the infield next year, since they are two rare Mets hitting well enough to justify everyday spots.
Just spitballin’ here.
