Yainer's DH Slash Line 0.208/0.226/0.366 I expect a lot of this is small sample, but some guys can't handle batting when not playing in the field.
He was like our secret weapon against the Rangers, heh. Not for a lot of innings, but he came through.
How many "can only play 1B or DH guys can you carry on a team"? Especially when one of them is just a "test"? The answer is "one", if you were wondering. I think I'd find a more useful player, but you're not wrong.
I think they have to be wanting to keep them off the 40-man roster until next season when they'd by Rule 5 eligible. If so, it says they don't expect a major upgrade from either joining the team over Julks.
