It's one of sport's great rivalries - the New York Yankees vs Boston Red Sox - and soon American Mark Melancon will have lived both sides of it.
Drafted by the Yankees in 2006, the Colorado-born baseball pitcher made his major league debut against the Red Sox three years later and is about to join Boston for the coming season. But this week he's in Auckland, making good on a promise to help the sport finds its feet in New Zealand.
Twelve months ago, during a holiday cruise, Melancon gave up a day of his Auckland stopover to conduct a clinic for local youngsters. Now he's back with San Diego Padres catcher Nick Hundley to run a five-day camp and prepare the national junior team for the Oceania Championships later this month.
"New Zealand is the most beautiful country I've been to and has the nicest people," he recalls of his previous visit. "I can't wait to retire here, hopefully. Nick and I have been great friends since college and we complement each other well on many levels. That's why I wanted to bring him here and help transform New Zealand baseball into something special. I know New Zealand is capable of being a heavy hitter in the baseball world."
Visits from MLB scouts, coaches and players have become more frequent. Last year, Yankees centrefielder Curtis Granderson proved a popular guest and subsequently enjoyed a breakout season, leading the American League in runs (136) and runs batted in (119) with 41 home runs. Melancon (26) may be poised for just such a breakthrough himself. After a high school career that also saw him excel in basketball and football, he was initially drafted by the Los Angeles Dodgers but chose to take up a scholarship at the University of Arizona. There, he set a school record for saves and played for the United States national team.
