Plus, it's not like they're 'in love' with him or any other such nonsense you sometimes read. He was left off the roster on opening day but had to be added when Chourio couldn't go. He was then optioned a second time, but quickly returned when Lockridge was hurt.
There's a reason why teams usually don't !!!!DO SOMETHING!!!! at this point of the season--the cost of getting a trade partner to take an early plunge is usually prohibitive, especially when you aren't as equipped as others to just throw money at any organizational holes the extra cost might create, Plus, you're currently in a position where you don't need to panic. They have prospect capital, and I'm sure they're talking to other teams---about pitching, about the left side of the INF, about a RH OF bat. If anything, #3 is probably the least of the worries right now as your numbers point out.
The roster won't be the same in five weeks as it is now. It never is.
