I can understand I guess if you say Ortiz and Norby aren't ready so don't try holding spots for them. Both were successful, but Ortiz only had 115 PAs at AAA, Norby had 42 PAs. Give them a couple more months to see where they are, so a one year deal for a MI isn't so bad.
Westburg on the other hand had 413 PAs in AAA with a .869 OPS, 129 wRC+. Way more PAs than Adley, way more than Gunnar. Nothing more to do, he should be on the opening day roster and probably starting at 2B, unless perhaps he totally bombs in the spring. And not to be the short part of a platoon.
I was fine signing one of the SS cause it would clearly be a talent upgrade, then just figure out the other guys later. I don't get signing a guy who is a good fielder and you hope will be a league average hitter--you have that in Urias. He can't even play short. Oh but he can play some LF...well we have Stowers and Mullins and Santander who are lefty/switch OFs with Cowser coming soon hopefully. He's basically a better defensive Vavra I guess, which means Vavra won't have a spot and that isn't worth another $7M imo.
If there's not a trade coming I don't get it.
