Jimmy Boyce was on the New Zealand national team roster for the 2017 World Baseball Classic Qualifiers; his brother Joe Boyce was also on the team. He had moved to the United States in 2012 in order to find a more competitive baseball environment. He was the winner in New Zealand's 17-7 win over the Philippines national team on February 12th as he pitched an inning and a third of scoreless relief and was on the mound when his teammates took the lead for good. He got their lone victory of the tournament. He also got into their last game, relieving Scott Cone with a 6-2 deficit in the 6th against South Africa. He served up a walk to Jonathan Phillips and a three-run double to Kyle Botha but then worked another inning and a third without allowing a run before Jamie Wilson relieved. Ironically, his participation in the tournament endangered his future participation in varsity sports in the U.S. as Washington state high school athletic rules renders ineligible athletes who have competed in team sports with or against professionals (other states have more lenient rules that exempt those who are playing for their national team).
In 2021, he played in the Czech Extraliga.
