Is Berrios healthy? Is Pineda the pitcher he was id the second half before the suspension? Is Odorizzi the first half pitcher? Is Homer Bailey the better than league average pitcher he was last year? Is Smeltzer the low 4 ERA or FIP pitcher? Same for Dobnak? Does Hill rebound to where he pitches like he did for the Dodgers? If two of the first three questions have a no it is highly unlikely it matters who is available unless the offense is on pace to shatter the 1067 run record. For every no answer in the second 3, replace the name with Graterol, Thorpe, then Poppen. If you get to Poppens name and the Twins are not on pace to shatter the 1067 record it is highly unlikely it matters who is available. There are 2 scenarios were the midseason trade becomes important. One is that the offense has managed to put the team in first place despite less than best efforts from the middle and bottom of the rotation. If the top 2 are going good the team needs a third for the playoffs. The other scenario is Berrios is going great and the team pulls off a blockbuster because they don't think he can keep it up for a whole season but somebody else does.
