The Mets are all over the place. I have no idea what they are doing. I trust Stearns, but right now, the NYM only have 16 position players on the 40-man roster. I think 8 of them are infielders and 3 are catchers. Their #2 outfielder is Tyrone Taylor. It's early, but they need two more outfielders. And unlike the Astros, the NYM are in win-now mode. My suggestions:
Yoshida for Semien. I'm not sure Yoshida moves the needle for the Mets, but at least he owns an OF glove. This assumes they play Bo at 2nd.
Duran for McLean. He's not in the Chandler/Burns level, but still pretty much top-shelf. And this would allow us to include one of our pitchers in a trade.
TBH, I don't think the NYMs do either one, but they've dug themselves a hole.
