LONDON (AP) -- The defending women's champion has won her first match of the year at Wimbledon as have former men's champions Roger Federer, Andy Murray and Rafael Nadal (rah-fay-ehl nah-DAHL').
Second-seed Petra Kvitova (kuh-VIHT'-oh-vuh) needed only two sets to dispose of her first opponent in less than an hour and advance to the second round. Kvitova, who also won Wimbledon in 2011, pulled out of a warmup event last week at Eastbourne, England, citing a viral illness.
Federer, Murray and Nadal all advanced with straight sets wins as well.
The seven U.S. men in the Wimbledon main draw represented the country's smallest contingent since 1947. That number has been reduced to five as Jack Sock, the 31st-seed, lost his first round match, as did unseeded Tim Smyczek. Sam Querrey (KWEER'-ee) of the U.S. won his.
There were two upsets on the women's side of things as Eugenie Bouchard (boo-SHARD'), who was runner-up at Wimbledon last year, fell in the opening round to a qualifier, while third seed Simona Halep (HAL'-ehp) became the highest seeded player eliminated so far, losing to the 106th ranked player in the world.
The Williams sisters, Serena and Venus, have pulled out of women's doubles at Wimbledon. The tournament referee's office announced the withdrawal and did not give a reason.
The duo has won 13 Grand Slam doubles titles as a pair, most recently at Wimbledon in 2012. In doubles at the All England Club last year, they stopped after three games in the second round, because Serena was ill.
UNDATED (AP) -- Pittsburgh's Gerrit Cole is looking to become baseball's first 12-game winner tonight when he takes to the mound in Detroit against the Pirates. Cole, who is 11-3 with a 2.16 earned run average, will square off with former American League Cy Young Award winner Justin Verlander.
Another top-notch pitcher is in action this evening in St. Louis as Chris Sale of the White Sox faces the Cardinals. Sale has a streak of seven straight outings with at least 10 strikeouts in the game. The lefty has fanned 85 batters during the run.
The Houston-Kansas City three-game set continues this evening on the Astros home turf. The home team won the opener of the series last night 6-1. Working the rubber for the Astros this evening is nine-game winner Dallas Keuchel (KY'-kehl).
The remaining games tonight feature the Rangers in Baltimore, the Phillies home to the Brewers, Boston at Toronto, the Indians at Tampa, the Reds home to the Twins, Chicago's Cubs in New York for a game with the Mets, Miami entertains the Giants, the Dodgers are at Arizona, Oakland is home to the Rockies, New York's Yankees are playing in Anaheim against the Angels, Seattle is at San Diego and the Braves are hosting the Nationals. In the National League East, the Braves trail the first-place Nationals by six games.
BALTIMORE (AP) -- Josh Hamilton has been activated from the 15-day disabled list by the Texas Rangers. He was sidelined since May 31 with a strained left hamstring and has played in only seven games this season, batting .273 with two homers and five RBIs.
OKLAHOMA CITY (AP) -- The Oklahoma City Thunder have sent Luke Ridnour and cash to the Toronto Raptors in exchange for a trade exception and the rights to forward Tomislav Zubcic. The Thunder will have one year to exercise the trade exception.
It was just the latest move for Ridnour as he was dealt to Charlotte last Wednesday in a deal involving Memphis and then almost immediately was sent to the Thunder along with a conditional 2016 second-round draft pick for guard Jeremy Lamb.
Ridnour has played for five NBA teams in 12 years and has a career scoring average of 9.3 points per game.
CLEVELAND (AP) -- Tristan Thompson, Matthew Dellavedova (dehl-uh-veh-DOH'-vah) and Iman (EE'-mahn) Shumpert all received qualifying offers from Cleveland, meaning the Cavaliers can match any offers those players get from other clubs this summer. Thompson is of particular importance to the Cavaliers, who went to the NBA Finals this past season. He has appeared in 308 consecutive games, has averaged 10.1 points and 8.4 rebounds over his career and saw his stock soar by averaging 9.6 points and 10.8 rebounds in this year's playoffs.
The Cavs have also announced that forward Mike Miller exercised his $2.85-million option for next season.
SAN JOSE, Calif. (AP) -- The San Jose Sharks have worked out a trade with Boston to secure the services of goalie Martin Jones. The Sharks sent a 2016 first-round pick and unsigned forward prospect Sean Kuraly to the Bruins for Jones. Jones had a short tenure in Boston, having been dealt from the Los Angeles Kings to the Bruins last Friday during the draft in a package for left wing Milan Lucic (LOO'-cheech).
-- Alexander Semin's (SEHM'-ihns) time with the Carolina Hurricanes is over. The Hurricanes placed the forward on unconditional waivers with the intent to buy out his hefty contract. Semin must clear waivers at noon Wednesday before his deal can be bought out. Under the league's collective bargaining agreement, he will be owed $14 million, two-thirds of the amount remaining on his deal, over six years.
-- The Calgary Flames have signed Dougie (DUH'-gee) Hamilton to a six-year contract. The Flames acquired Hamilton from the Boston Bruins on Friday for the 15th, 42nd and 57th picks in the draft. Hamilton is coming off career highs in goals, assists and points.
-- Forward Brian Flynn has agreed to a two-year contract with the Montreal Canadiens. He was acquired by Montreal from the Buffalo Sabres on March 2 for a fifth-round draft pick. Flynn had 17 points in 54 games for Buffalo and no points in nine regular-season games for the Canadiens.
-- Drew Stafford is staying with the Winnipeg Jets. The Jets have signed the veteran winger to an $8.7-million, two-year contract. The 29-year-old had nine goals and 17 assists in 26 games with the Jets last season.
