The Berkeley Revolution Unicycle Basketball team, ranked second-best in the world at last December’s World Championships in New Zealand, squares off tonight against the perennial world champs from Puerto Rico. It’s sure to be a barn-burner. The Revolution has a fair amount of height and plays a controlled, technical game. Puerto Rico, meanwhile, plays a more physical game built around tenacity and strength. The two have yet to match up in formal play — until tonight. Both teams have been sizing each other up for over a year and are excited to compete. The Revolution has home-court advantage and goes in as the top seed, yet things could go either way. Watch the semifinals and finals tonight at Berkeley High School (2223 Martin Luther King Jr. Way, Berkeley) from 8-10 p.m. Tickets are $5.
