I do think not counting Correa's earlier IL stint matters greatly in comparing his usage to Witt Jr. and Judge. Nobody will play all 162 for Baldelli IMHO, but if Correa and Lewis were healthy and showing no symptoms of fatigue, they would play in over 90% of the games. Correa was in the top of the order most of the time and when Lewis was hitting like a superstar, he was too.
At times, Miranda and Wallner have looked like they should be permanent middle of the order bats, but so far they haven't demonstrated the consistency to write their names in ink in the lineup every day and maybe in a specific place in the order.
It seems to me that Rocco really shields his younger left handed batters from left handed pitchers. The four at the beginning of the season were Wallner, Kirilloff, Julien and Larnach. None have performed well against lefties, but is it because they haven't seen enough of them or because they aren't that good? By mid-season, Julien and Wallner had been demoted (then returned) and Kirilloff slumped miserably against all pitching. So maybe they just aren't good enough hitters to play every day. It's a chicken and egg thing IYAM.
Baldelli seems much more willing for the Martins and Margots of the world to face right handed pitching. My biggest gripe against the Twins' manager is the quick hook for lefty swingers in games. I've heard the stats over and over, but having a Margot or Martin face a right handed pitcher (instead of say Wallner or Larnach) in the seventh and ninth innings seems like a horrible miscalculation.
It's very apparent that Baldelli isn't going to trust rookie starters to face a lineup for the third time unless they are absolutely rolling. August/September Pablo has his trust and Ober and Ryan (prior to injury) were on their way. He won't overuse his bullpen guys in the first half of the season. This late in the year, he's leaning heavier on his few reliable bullpen arms. So far Jax, Durán and Sands are holding up, but Alcala is questionable. If Rocco doesn't overuse his key guys, others are going to have to pitch in high leverage and no one else has stepped forward.
All I've ever heard about the club outside the lines is that Rocco is well respected and that the players get along well. I think discipline is handled privately. Baldelli isn't one to publicly berate his players. Does this supposed "loose ship" make for poor fundamentals? I don't know. Maybe there shouldn't be three converted infielders in the outfield. Sometimes you play with the cards you're dealt.
On balance, I don't think Baldelli is the problem. I think he can do a better job, but the same is true with about 29 other major league managers. It's mostly the players that win games.
