Major league average for saves converted is 61%, and inherited runners scoring is 35%, 5 years ago those numbers were 66% and 30%, so I think bad relief pitching is MLB wide. I think part of the problem is the three batter rule, though this years and last years numbers for those two stats are on par with 2019, the last year of the specialist. I think this rule puts pitchers in a position to fail because they are either brought in one batter too soon or left in for too long. I'm not saying this is the Twins problem, but it seems the relievers give up a big hit to the first or second batter they face then settle in, or get the first two batters out then fall apart as the manager tries to get said pitcher to finish the inning. Just my $.02 worth.
