One of the most exciting American players on the ATP World Tour, John Isner, will be the No. 1 seed at Newport. Last year, he captivated tennis fans around the world when he triumphed in the longest match in tennis history – an epic 11 hour and 5 minute battle at Wimbledon, versus Frenchman Nicolas Mahut. Following that record-setting match, both Isner and Mahut donated personal memorabilia (Isner’s racquet, Mahut’s racquet and apparel) from the match to be displayed in the Museum at the International Tennis Hall of Fame, where it is currently showcased in the Grand Slam Gallery. Last year, Isner  finished in Top 20 for first time with a personal-high 38 match wins. In addition, he led ATP World Tour in aces with 1,048 served – 113 of which were in the epic Wimbledon match.

Ryan Sweeting, a rookie in the Campbell’s Hall of Fame Tennis Championships, is one of the early contenders for this year’s ATP Newcomer of the Year honors. Ranked No. 116 when the 2011 season began—with 12 match wins on the ATP World Tour scattered across sporadic tour play the past few years—Sweeting almost doubled his career wins total in the first five months of the year. He captured his first ATP title by winning the U.S. Men’s Clay Court Championships in April and, one month later, rose to No. 65 in the world. Sweeting also was a quarterfinalist at Delray Beach in February, earning the first Top 25 victory of his career when he upset Sam Querrey in the second round.

The pattern Olivier Rochus has developed in playing the Campbell’s Hall of Fame Tennis Championships the past two years suggests that he will win this year’s event. Upon his debut in 2009, he advanced to the semifinals before losing to eventual champion Rajeev Ram. Last year, Rochus breezed to the final, where he fell in three tight sets to Mardy Fish. During his 13-year career, Rochus has captured two ATP World Tour singles titles, the most recent five years ago on clay at Munich. The biggest championship in Rochus’ portfolio is the Roland Garros men’s doubles title he won (with Xavier Malisse) in 2004.

Nicolas Mahut is the only player in the Campbell’s Hall of Fame Tennis Championships field who has items—not just his name on a trophy—in the Hall of Fame Museum. As one of the competitors last year in the longest match in history, Mahut donated a shirt, shorts and autographed sneaker to the Museum to commemorate his record-shattering 11-hour, 5-minute epic (spanning three days) against John Isner in the first round of Wimbledon.  Fans in Newport, however, were already familiar with Mahut; he has played the Hall of Fame Championships the last five years in a row—in addition to 2004, when he was a doubles finalist. Mahut was singles runner-up in 2007, capping a stretch of winning 10 of 13 matches on grass, including a straight-sets upset of Rafael Nadal at Queen’s Club, London.

Before this week, Ivo Karlovic had not played the Campbell’s Hall of Fame Tennis Championships since 2006, when he was forced to retire from his first-round match because of a knee injury. On the comeback trail now from an Achilles injury, Karlovic is a better player than he was then, having risen to No. 14 in the world in the summer of 2008 on the strength of winning the pre-Wimbledon event at Nottingham for the second year in a row and reaching the semifinals of the ATP Masters 1000 event in Cincinnati, where he defeated Roger Federer in the round of 16. The following year, Karlovic was a quarterfinalist at Wimbledon, defeating Top 10 players in back-to-back matches for the first time in his career. Karlovic’s serve, clocked at a record 156 mph in March, gives him a chance against anyone, but it is particularly potent on grass.
