The last time the Pittsburgh Pirates had five All-Stars, there was no designated hitter, baseballs were made of horsehide and the major leagues had 24 teams. That was 1972, when Roberto Clemente, Willie Stargell, Steve Blass, Al Oliver and Manny Sanguillen represented the defending World Series champions at the National League's 4-3, 10-inning win in Atlanta. With the addition of reliever Mark Melancon as an injury replacement Sunday, the Steel City has a fab five once again. Seeking to end a record streak of 20 consecutive losing seasons, the Pirates are 56-37 at the All-Star break and contending for the NL Central lead.
