Tony Delvechio is an Italian-American and older brother of Angela Delvecchio. He brags about how good he is at sports but a pretty good player around the league.
Tony is a Caucasian with a purple t-shirt (comes with a silver vest over it), jeans, and white low tops, making him dressed like 1950's greaser. He has dark brown hair with bangs. In later games, like Backyard Baseball 2005, he looks different because his hair looks like an afro with a curly bang. In Sandlot Sluggers he wears dark jeans, a black shirt, leather jacket, sneakers, and his hair is even slicker.
Tony is a bragger of the group and thinks that he is the best there is in the league. He is pretty good in every sport but does not like his sister, Angela on the same team with him. Tony also has the tendency to overwork himself at sports. In the book " Inside the Edge" , he played on his older brother, Vinny and his friends' team at the same time. Tony became overworked being on the same team but wants to become the best player he can be.
- In the original Backyard Baseballs (pre-2005), Tony shares his stats with a generic player named Lena Ng, who shares the same stats with another generic kid by the name of Jim Kiley.
- Angela and Tony are the 2nd generation (along with their siblings) of Italian-Americans in their family. (Mentioned by Angela in Backyard Football 2001)
- Tony's aunt's second cousin husband plays Soccer in Italy (Mentioned in Backyard Soccer MLS Edition)
- He's secretly known to be emotional such as crying (Angela stated this many times in most Backyard Sports games). Also, his name is a reference to Tommy Delphinio.
- In Sandlot Sluggers, he is captain of the "7th Street Sluggers" and in Rookie Rush, he is captain to the "7th Street Brawlers", playing his home games in both titles at "Concrete Canyon".
