Phil Hughes will wear 45 (not 34 as this infamous tweet speculated) https://twitter.com/MikeBerardino/status/407765120534589440
Also, this article notes coach Scott Ullger giving up 45 for Hughes (switching to 41). And that he did the same thing for Terry Mulholland in 2004.
Ricky Nolasco will wear 47.
Kurt Suzuki will wear 8.
Jason Bartlett will wear 11. He was 18 during his first stint with the Twins, but that number is currently worn by bullpen coach, Bobby Cuellar.
And Eric Fryer switched from 54 to 26. That's all I see for now, bye!
