Starter or Releif Ace. Make the choice and keep on it...we don't ant another Fernando Romero situation.
The Twins do NEED another to-flight starter. Better than Kyle Gobson 2018, period.
They can patchwork a 5th starter, or hopefully Dobnak or Thorpe will step up and grab the spot.
I can also live with people getting innings during the beginning of the year, especially when you don't need a fith starter arm...and taking looks at people like Smeltzer, or perhaps Graterol.
But using Graterol as a long man means you are basically adding a 3-4 inning bullpen arm being used minimal. Better to have ONE guy share his SPOT WITH ANOTHER, or an arm that could pitch three out of five days if needed.
Of course, the need to now face three batters within an inning will change bullpen makeup and management...shaken out during the season, I imagine. Still don't see it being as big of a deal. You can still bring in a guy to close an inning and not use him the next inning. But you will have to carefully judge warmups and batters faced, esecpailly with an extra offense bat on each roster, too.
