Bernardo Fallas' Notes Column tells us that Geoff Blum will get the majority of his time at 2B, while Sanchez will get the majority of time at SS - though could see time at 2B himself.
Mills, on Blum:
"We're going to be in a situation where it's going to be tough to get Blummer in there all the time. We don't want to kill this guy either. He's been a guy that will do a great job for us, but to put him out there every day might be asking an awful lot of him."
On Sanchez at SS:
"I think (Sanchez) has earned a shot to play there quite a bit."
We didn't come out here to play tiddlywinks, son.
