Southwest Miami High School's boys basketball team, led by five-foot eight-inch point guard A.J. Castro, gave its win-starved fans much to cheer about this year. After decades of lackluster seasons, the Eagles squad tallied a 22-7 record, upsetting perennial powerhouses and reaching the county finals for Class 6A play. At one point the gutsy Cinderella team was ranked second in the state. At the heart of the dream season was the team's fast and slippery playmaker Castro, who frustrated many a taller opponent. On the court he is fearless, taking control with lightning-quick passes, nervy rebounds, and wicked three-point shots. And he has a knack for scoring when the team needs it most. During the Eagles' final regular-season game against their district rivals, the South Miami Cobras, Castro whooshed an arching three-pointer that won it for the Eagles as the clock ticked off its final second. The short guy was named to the first-string all-state team by the Florida Sportswriters Association, the McDonald's All-American Team, and the county all-star roster. Not bad for a scrappy Cuban kid from the burbs. He's a senior now, and when he accepts that scholarship to Cornell, as expected, the hoops around Westchester will never be the same.
