Manager Ron Gardenhire explained to us in a Peanuts from Heaven exclusive:
Gardy: We've got a young pitcher whose going to start on Saturday.
PFH: Oh, yeah Gardy? Which pitcher is that?
Anthony Swarzak: SWARZAK!
Gardy: He's a young gun from Rochester with a hellacious sinker.
Gardy: He's coming up to cover Perk, who seems to be a little hurt.
PFH: But wouldn't that be bad for Perkinses career and salary?
Gardy: Naw, if you get hurt and miss work, just call this kid and it won't hurt to miss work.
PFH: Which kid?
Gardy: And he doesn't give up runs, which is just as good as scoring them.
PFH: How very zen Gardy...
Anthony Swarzak: ask about him at the Metrodome.
