Upon seeing the name of the Twins player in the article, it's no surprise that he performed at an elite level as a September callup. MLB says Hall-of-Fame outfielder Tony Oliva is best September callup in Minnesota Twins historyMLB is right, as the Twins called Oliva, a Cuban native, up in September on two separate occasions, and both times the now Hall-of-Famer proved he belonged at the big-league level.
