I think he's referring to Baseball Info Solutions Defensive Runs Saved Above Average. BBref has Wallner at -7, oops it just changed (lol, they must be updating data), his Rdrs is -5, tied for the worst in MLB at ANY position, with Brooks Lee.
Jim Kaat was 34 when the Twins released him and Rod Carew was 32 when traded to the Angels, not exactly in their prime. Blyleven was traded after refusing to sign his contract. Heck, even the fans booed him in his last start as a Twin. I don't think they were driven out.
Yeah so far I think Shelty has done a good job. Nothing really stands out but I like that he is giving the starting pitchers some length, but that just might be to protect a suspect bullpen.
The last 2 years we started 6-10 and 5-11 after 16 games so this year feels a whole lot better. And I like that we have been scoring early in games and pounding some left-handed starters.
Taking a series in Toronto feels especially good as usually we have a hard time with them. Go Twins.
