Porirua teenager Te Wera Bishop is set to sign a deal to join baseball giants the Boston Red Sox.

Bishop, 17, who made his international debut for the New Zealand men's softball team against Australia, will ink a contract in Auckland in Thursday and join up with Red Sox for spring training on March 1.

The catcher is taking a step in the unknown, but is excited by the challenge.

"I don't know what to expect," he said. "I'm just over the moon."

Black Sox coach Eddie Kohlhase had earmarked Bishop for a big future in softball, but he has no qualms about the teen pursuing a baseball career.

"This is an opportunity that everyone dreams of and for a young man from Wellington to be given this opportunity says a lot for his family and the Black Sox," Kohlhase said.
