Mark Kotsay had two stints with the Padres. His first was from 2001-2003, as the team’s starting center fielder. His second is this season, as a valuable veteran presence and left-handed bat off the bench.
This particular card is from the 2003 Donruss Diamond Kings set. It’s not the base card, but the silver foil parallel. I believe these were numbered to 400. While I enjoyed the Diamond Kings sets, I preferred Diamond Kings when they were subsets/inserts of the main Donruss set.
Mark’s not doing that badly, currently hitting .292 off the bench. Of course, since the Padres are mired in last place this season, his name has been bandied about in trade rumors. Veteran left handed batters are usually in high demand among contending teams around this time of year.
