The Miami Herald (Sarah Rothschild) reports: The Heat lost 96-91 to the Memphis Grizzlies at AmericanAirlines Arena on Friday, assuring itself of the worst record in the league when the season ends and, more importantly, the best chance to secure the top pick in the NBA Draft. By finishing with the fewest wins, the Heat has a 25 percent chance of getting the top overall pick and a 44 percent chance of landing the first or second pick. The team is guaranteed no worse than the fourth pick. The Heat will learn its fate May 20 in the NBA lottery drawing, which determines the order for the June 26 draft. A projected top pick, Kansas State forward Michael Beasley has scheduled a news conference for 5 p.m. Monday, when he likely will announce he intends to enter the NBA Draft. Memphis point guard Derrick Rose, another projected top pick, has not revealed his plans but is expected to turn pro.
