Well, if you'd really like to know for the future, I did this:

1. The Gary Rath was legible/discernible enough that I initially thought it said Gary Ratt, so I used baseball-reference.com and searched on players with that name. No luck, so I searched for those starting with "Gary Ra". Results showed Rath and right time frame, so clicked on him, saw his Twin connection and figured on right path.
2. So i then went to ebay and searched on Gary Rath autos and saw it was a match, so one down
3. Went back to baseball-ref, 99 Twins, and skimmed for someone with initials DP. Found Perkins as a possibility, and then did ebay & google searches. Found very similar in style, I think the Dl is scribbled Daniel and the PL is really Pk.

Again your question was most likely rhetorical but wanted to share baseball-ref as a great research resource.
