Least important only in your world.
The Twins got a full time 1st Baseman before Kirilloff was hurt, if 1st base was so unimportant they would not have done that.
Kirilloff was lousy there which is one reason they brought in Gallo who was a very good fielder.
Santana saved their buttocks many times.
Least important is bollocks, double plays need a 1st baseman , especially with the Twins can dig out, reach out and just plain stop pissant throws to first to astray.
They were not patient with Kirilloff, they will not be stupid and have a mediocre player there, ever.
