What makes Diamondbacks' Ketel Marte's hitting streak so unique?

Arizona Diamondbacks second baseman Ketel Marte ended one of Major League Baseball's rarest streaks in history. Not his 18-game hitting streak — he kept that intact during Sunday's 6-4 win against the Detroit Tigers in a loud way. The streak he ended closed during his next at-bat when Marte singled to right field. The switch-hitter had exactly one hit in 15 consecutive games entering Sunday, which had only been done three times, according to Baseball Reference's database.
