I think that the roster decisions that need to be made soon are a bit more complicated than "dropping a reliever and picking up Vargas". Here are the complications, on early roster decisions: They soon need to decide on Adrianza and O'Rourke, both about to come out of the 10-day DL and out of options. Easy decision for me: DFA both and see if they clear waivers.Their "best bet" to come up from Rochester (Park) is hurt with hammy issuesThey have pitchers with options in the majors (Duffey, Mejia) but one has been a starter and the other lights out.The best player for bench depth and versatility for the Twins, right now, might not be Vargas, but Niko Goodrum, who has been on fire in Rochester (.353/.389/.647) and can pretty much play every position but catcher.When Molitor is looking and his bench and being disgusted, he is looking at Mr .143 as well (.143/.143/.143), below replacement level, Danny Santana (who is out of options.)In SSS Tonkin has not been awful (but 100% LOB and 0% FB/HR might change that quickly upon regression to normal), but has career lows in K/9 and BB/9. But still is SSSBreslow, on the other hand, has bigger issues: The arm angle change experiment that was supposedly going to help him increase his velocity, has failed. His velocity this season is 2 mph below last season, and 87 mph fastballs do not cut it. What I would do? DFA Breslow and Santana, bring up Goodrum and Vargas, and after Park returns, depending on performance, flip with Vargas (who has options).
