If Lindor is out past May, we really need to go get a bit more infield help.
Stamets is a good fielder, but we can't have a .125-.150 automatic out guy in the lineup for more than the next few weeks at most.
Chang makes the most sense. The only other free agents out there that I can even find that play the non-1B infield positions are Jose Reyes, Danny Valencia, and Andrew Romine, which is the biggest group of stooges I've ever seen.
Getting Kipnis back relatively soon would be nice. Kipnis isn't a savior or anything, but throwing him out there instead of having two of Moroff, Miller, or Stamets everyday will make a huge difference.
A lineup against righties in two weeks of:
CF - Martin
2B - Kipnis
3B - Ramirez
1B - Santana
DH - Ramirez
RF - Gonzalez
LF - Allen/Bauers
SS - Miller
C - Perez/Plawecki
Could do worse. Miller isn't the worst stick in the history of mankind or anything.
