Rocco Baldelli is what "F" looks like. Pitching has been covered so I won't rehash that.... let's talk about offense and defense.
First, the offensive numbers don't look terrible from a purely statistical standpoint but game over game... yuck. The Baldelli Twins have a mentality that the only way to score runs is the the long ball. Go back and watch all of the Twins extra inning games this year. While the other teams are bunting to move the runner on second into scoring position, the Twins are primarily swinging (and missing) for the fences. There were also way too many games where the Twins scored in the first or second inning and then phoned in the rest of the game. That shouldn't happen. They should be taking quality at-bats throughout the entire game.
Second, the defense. On paper, our team was supposed to have a strong defense and historically, the Twins have been known for a strong defensive mindset. There were some injuries which impacted defensive quality, but the Twins played sloppy defense overall. Simmons, a former golden glove SS, didn't look great. He had great range to get to balls but made a lot of bad throws and/or failed to throw at all. Sano was a trainwreck at the easiest defensive position in baseball. I also witnessed a lot of throws from the outfield that did not utilize the cutoff man properly. This comes down to poor preparation and inadequate fielding routines.
Baldelli has either ignored or forgotten about the fundamentals of baseball. The Twins will continue to suffer until he makes an adjustment or he is fired.
