Witt Jr. is having a tremendous season. With his combination of speed and power, he has amounted to 33 HRs and 31 stolen bases (not quite Ohtani level, but very impressive), helping his club be in the playoff run after a dismal season last year.
This video goes through Witt Jr's notable cards in his career. One that pops out to me is the father and son card, with his father Bob Witt Sr., which is also signed by both. Pretty cool!
