You can get him at Cardinals Winter Warm up in January, he is generally there each year, or maybe via his team, but I think he is mostly in person stuff, but lots of people have his stuff on here, in fact, there is a trader on here named Butch who has some Worrell stuff for sale:
1987 Topps 7 Worrell, Todd Cardinals NP A
1987 Topps 456 Worrell, Todd Cardinals P A
1987 Topps 605 Worrell, Todd Cardinals NP A
1992 Stadium Club 703 Worrell, Todd Cardinals NP A
1993 McDOnalds Cardinals 54 Worrell, Todd Cardinals NP A
Not sure if you are looking to buy, or if he is interested in trading, but I bought some stuff from him a few weeks ago, and it was great quality, hope this helps!
God Bless,
