FORT MYERS, FLA. — The Twins are going to start Jamey Carroll at shortstop and Alexi Casilla at second base, and they don't have a backup for the middle of the infield.
Brian Dozier is destined for reassignment to the minors. Pedro Florimon, claimed on waivers from Baltimore in December, can field but can't hit.
The player who fits the profile as a backup infielder spent his fifth day in minor league camp on Saturday, playing for the Class AAA Rochester Red Wings.
Tsuyoshi Nishioka and his $3 million salary were sent across the parking lot on Monday. The Twins knew this was a traumatic event for the 2010 Japan League batting champion and told Nishioka that he could take a day off before reporting. He passed on that and showed up early Tuesday in the minor league clubhouse.
"He's taking everything in and trying to get better," Rochester manager Gene Glynn said. "I don't know how it is for him on the inside -- it has to be tough -- but we haven't seen that. His effort has been excellent."
The Twins' stance over the winter was that Nishioka's broken leg in the sixth game of 2011 made it a rookie season for him. General Manager Terry Ryan expressed hope that being sound physically would help Nishioka to be sound fundamentally.
It didn't work. The same flaws in the basics of infield play existed early in exhibition games, and the Twins decided quickly to option the 27-year-old to Rochester.
Nishioka has been with the Red Wings for five games and has played all but three innings. He has played three games at shortstop and on Saturday made his second start at second base.
