Bartlett played bad defense in spring training..?

Is Jason Willimas the worst local sports writer? I read today's article in it he states that Bartlett did not make the team out of spring training because of his defense.

"He struggled defensively in spring training, leading the Twins to send him to Class AAA Rochester to start the season. Gardenhire challenged the soft-spoken Bartlett to become a take-charge leader in the infield. Some in the organization were starting to wonder if Bartlett, 26, ever would become a reliable everyday shortstop."

Who didn't think he could play shortstop? Why? These are the questions I want answered.

He never showed anything but quality defense. Out of spring training Castro had made 7 errors. Yet they kept that slug on the team over a much better Bartlett. It couldn't have been because of defense. Bartlett showed much more range and equal if not better hands.

The leadership issue makes me gag. I still am at a loss as to why Bartlett was off of the team to start the season. Jason W. should really find out the real reason.

Could they truly believe that Castro was a better fieder?
