In the mid-2000's Donruss was the parallel kings. Many of their parallels were inexplicable and extremely difficult to keep track of. The Sportscasters inserts were one of my favorite insert sets from the time period, but there were so many different variations of the cards, it was very difficult to know what you had. These cards are based on the 1970's multi-sport sets of oversized cards and have a similar design. I just recently picked up these two Yaz cards in an Ebay auction. They are my first Yaz cards from the insert set, but I did previously have a Pedro Martinez.
