I have tried him ttm several times in the past, both via home and his team (River City Rascals) and had no success. You may get someone in the area to 50/50 via his team, they play indy league ball in the STL area.
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!
