The Twins have entered the final week of spring training with a lengthy to-do list. At least they were able to scratch off one item on Sunday.

Twins manager Ron Gardenhire officially named rookie Aaron Hicks his starting center fielder. Sure, it became a foregone conclusion when Joe Benson was cut from camp last week, but we had to have the announcement so we could ask the young man how it felt.

“It feels great,’’ said Hicks, who’s batting .350 with four home runs and 16 RBI this month. “It’s everything I’ve been working hard for ever since I’ve been playing baseball, so it just feels really good to be named center fielder.’’

With that out of the way, we can focus on unanswered questions this week at the Lee County Sports Complex.

Who’ll be the Nos. 4 and 5 starters?

Cole De Vries, with a 0.64 ERA this spring, should join Mike Pelfrey, Vance Worley and Kevin Correia in the rotation. Scott Diamond, the only lefthanded starter, will join them on April 12, provided he completes his return from minor elbow surgery. P.J. Walters is being stretched out but lasted just three innings on Sunday and doesn’t have enough time to build up to 90 pitches. That leaves Liam Hendriks (4.74 ERA), but he hasn’t pitched as well as De Vries.

Samuel Deduno should be in the middle of this battle, but he has a sore left groin and will not pitch until he’s 100 percent. He’ll have to throw in the bullpen before he’s allowed to start a game. Unless he wakes up over the next three days cured, his window of opportunity appears to have disappeared.

Keep in mind that April 7 is the first day the Twins will need a fifth starter.
