I think Ohtani held things up a bit and Darvish looks like he's holding up the SP market. The top three relievers haven't signed but most of the other usable bullpen arms have.
There's not much in the way of good up the middle talent this year. Everyone's waiting on guys like Hosmer, Moustakas, Martinez and Frazier but we've see the last several years that teams these days are only luke warm on corner bats. I'd guess the top bats and agents are waiting to be presented big contracts like the prior top bats from years past but these guys are playing positions that holds much less interest than before. I think the offensive inactivity is largely due to there not being much to covet on the open market.
Pitching? Well I just hope that market is being held up by Darvish who is coming to Minnesota.
