Some defensive updates:
Espinal is the 2nd best 2B in baseball. Unfortunately,
Schoop (not known for his defense) has arguably been playing the best D of any player in baseball regardless of position.
Chapman is the 2nd best defensive 3B so far in the AL (behind Kevin Smith).
Bo is in the bottom 5 but has been significantly better of late.
Tapia's defense has dramatically improved to the point where he's doing about as well in LF as Zimmer is in CF (for the record, Tapia isn't a significantly worse option than Gurriel right now because Gurriel is an albatross when he isn't hitting.
And then there is the captain. He's current 8th in catcher defense. This is why Heineman had no business being anywhere near our roster (it should be noted that Kirk has actually posted better numbers than McGuire so far this year). With this massive improvement, the Kirk to DH train becomes more of a Kirk or Jansen should be DHing a lot of days that they aren't catching.

Note: I filtered all positions to minimum 100 innings to take out noise.
