Despite all his successes, Unsworth's family hasn't seen him pitch professional, fueling his drive to make it to the majors.
"It's pretty expensive for them to come over," he said. His mom emails him daily with words of inspiration, quotes from successful athletes. "It's not great (being removed), but it makes me want to achieve more so that one day they will be out here. That's my goal."
Lorraine said Unsworth had a chance to make global impacts.
"South Africa is definitely not a baseball country historically," Lorraine said. "Dylan would like to be the first South African to make the big leagues — I'm sure every South African kid does. He's got the driving force to do it.
"When he goes home, I'm sure people say, 'Baseball ... what the heck is that?' But maybe, one day, he can put it on the map as a major leaguer for the Mariners."
Lorraine also called Unsworth a positive clubhouse presence. Beyond the field, he's a team player and a motivator on off-days, Lorraine said. The world class experience gives him an admirable background that is hard to find in any of the major league ranks.
"I've met kids from all over the world," he said, adding there may be a growing trend another South African — second baseman Anthony Phillips — playing with the High Desert Mavs, another Single-A Seattle affiliate. "Baseball is obviously an international sport, but I think in some countries it's starting to grow more. That sums up Africa."
If the Mariners' global phenoms pan out, it could lead to a new trend in baseball.
But Unsworth prefers not to think about his stats, his impact or his general dominance. Only the next batter up and the goal to send him down.
