Pete Sampras fears injury will keep him out of Davis Cup 桑普拉斯担心伤病会使他不能参加戴维斯杯

Wimbledon champion Pete Sampras has cast doubts over his appearance in the upcoming set of Davis Cup matches.
　　The seven times men's champion battled the pain of tendinitis in his left shin during the Wimbledon fortnight and visibly hobbled his way through several matches.
　　The Davis Cup semi-final against Spain will be played on clay in Santander between 21st and 23rd of July and captain John McEnroe names the team on Wednesday.
　　And Sampras has already admitted his participation is unlikely.

桑普拉斯可能放弃戴维斯杯

　　七次夺得温布尔登冠军的桑普拉斯在温布尔登比赛的两周里就在不断的同左胫骨肌腱的伤病斗争，在多场比赛中，蹒跚的步履已经明显影响了他的发挥。
　　美国队与西班牙进行的戴维斯杯半决赛将在本月21日到23日在西班牙桑坦得的红土场进行，美国队队长麦肯罗将在周三宣布美国队参赛选手的名单。
　　而桑普拉斯已经表示他不太可能参加这场半决赛。
