The last disabling injury was............Lewis(?), now that I think about it, it was Miranda. It would seem to me that someone will come up lame in the near future. Injuries seem to come in bunches and cluster in certain positions. Right now, it is relief pitchers and infielders.
The Twins current outfield has the following OPS--LF (Gallo 103), CF (Taylor 83) RF (Kepler 100). The primary backup is Castro (89). The Twins need better production than that from their outfield. None of those guys are much better against left handed pitching. They need to add an outfielder who can hit lefties. Pham (character) and Canha (contract) aren't ideal gets, but they fit the bill as far as hitting left handed pitching.
More bullpen please. Piecing things together with the likes of Balozovic and Ortega is okay occasionally, but adding depth in the bullpen has to be a priority. Stewart's injury recovery seems to be slow and I, too, wonder if the 25 innings of dominance might be pixie dust. Thielbar has already been on the IL twice with the same injury and no matter how he feels, he might be close to suffering the same injury again.
