I think the stat cited referred to Vargas having a wRC+ of 161 in AAA and 163 in AA- with a combined OBP of .414- that's someone's numbers, who with options remaining, you just don't dismiss out of hand, even at age 25. To go back to 2015, there was a major disagreement/misunderstanding/miscommunication on Vargas' plate approach that played out when Vargas was up with the Twins. He was summarily demoted in mid-May by the Twins, even as he was the hottest hitter on the team for the month of May, a month in which he was slashing at: .366/.395/.561/(.957)... with a wRC+ of 164. His public comments in reaction to being sent down at the time were confusing, and demonstrated his own personal confusion to what the Twins wanted from him, to say the least. Of course, he struggled mightily in spot duty during two subsequent call-ups- his performance suggesting continued confusion on his part with respect to Twins expectations...; and with the subsequent offseason signing of Park, it's pretty obvious that the Twins came to the conclusion that his days with the Twins are numbered.
