Here's what I did to pick the cards shown (when possible): This is Samardzijas's second Opening Day start, so I've got the card from the season of Fergie's second Opening Day start. I could do the same with Grace, Sandberg, Dunston, Santo, Williams, and Sosa. I've also got the opening day count for today's Cubs lineup.
Jeff Samarzdija is making his second start today.
First Base (since 1900): Charlie Grimm and Mark Grace, 12 starts
Anthony Rizzo makes his second opening day start.
