"The Pirates have managed to stay up there partly because of and sometimes despite Roberto Clemente, their best hitter and, when healthy, their best ball player. But Clemente does not play all the time. Some days he says he does not feel well, and he is known to have a back condition at this time. Actually, the Pirates have a slightly better winning percentage without their best athlete in the 51 games he has missed than they do when he has played. The old Orioles, those legends famed for playing hurt, may not have understood Clemente today. The Pirates never faced a more important doubleheader than the one with the Mets today. They lost the first game, and Clemente benched himself in the second. This could have been the choice of an ailing man, but the trouble is Clemente has asked out of second games of doubleheaders when he was healthy, and when the next day was an off day. If there is one chap who is holding the Pirates together it is their man, Manny Sanguillen, who refuses to be substituted for in the position that is most substituted, catcher. Sanguillen is the rugged Panamanian who wants to play every day, gives the Pirates one of the league's better catching jobs, and is a leader. He also hits .320."
