Chipper Jones might need surgery "at any time" which would mean Aramis Ramirez has yet another shot at the All Star squad.
To recap all the avenues he could have to get to the game.
Placido Palanco is having serious back pain.
Chipper Jones is having serious knee problems.
Reyes and Tulowitzki are both having some problems.
If either Palanco or Jones can't make it Ramirez would be a show in. It's less clear if a shortstop can't make it, but since there are 2 other shortstops Ramirez could get the nod.
I have to assume Andrew McCutcheon would be taken first if position were not an object though. Ramirez has been one of the best hitters of late, but McCutcheon is second in the NL of all hitters in fangraphs WAR.
However, if a shortstop was out, and McCutcheon replaced him, then if an outfielder couldn't make it Ramirez could still fill in.
By the way, if you can't tell, I'm a huge all star fan and I want to see more Cubs there!
