New kid / Tim Green.

Enhanced descriptions from Syndetics:

It's bases loaded, bottom of the ninth, and Tommy Rust is up at bat in the championship game. This is the moment he's been waiting for. But then his father barges onto the field, and Tommy knows what will happen next. They will be leaving immediately -- again -- because Tommy and his dad are on the run.



Now Tommy is in a new school, in a new town, and he is no longer known as Tommy. Brock Nickerson is the name of the new kid, and finding a place for himself is proving to be a challenge, especially when his new friend is the bully from the wrong side of the tracks. In an effort to fit in, he accepts a dare to throw a rock at the travel-team coach's window.

Coach Hudgens has demons of his own that he's dealing with, and many say he's "washed up." The travel team he's been running has lost every ball game in the last year. However, when Coach catches Brock in the act, he's more impressed by his pitching arm than angry at the prank. But can Brock save Coach's team...and maybe Coach himself Or will Brock's father make him be the new kid in yet another town
