MEXICO CITY — If Kyle Busch keeps this up, he’s going to have some difficult decisions to make.

Busch won his third consecutive race on NASCAR’s Nationwide Series, taking the Corona Mexico 200 by less than a second Sunday. He’s not committed to a full Nationwide schedule, but will he be able to resist a run at the championship?

“The consideration is there, but still, it’s a race-by-race deal,” Busch said. “We’ll make a decision here shortly. I love winning. I’ll run as long as I can win. That doesn’t bother me a bit.”

Busch wins no matter where he’s racing these days. He’s third in the Nationwide standings, second in Sprint Cup and first on the Truck Series. This latest win was the 27th of his career in NASCAR’s top three series, and first on a road course.

Marcos Ambrose finished a career best second after a hectic day in which he collided with Boris Said, knocking Said out of the race. Said didn’t leave quietly.

“He hooked my left rear in turn one,” he said. “He had me sideways for a while and then just turned me around. ... I’m not going to cry about it, but I’m going to go apologize to his crew chief because it’s going to cost him a car.”

Ambrose’s finish was his first top-10 placing of the year. He had six as a rookie in 2007.

Ambrose trailed by 1.139 seconds in his Ford with two laps to go, and Busch was able to hold on for a 0.737-second win.

Silvestro gets her first victory

LONG BEACH, Calif. — Simona De Silvestro, the only woman in the 23-car field for Sunday’s Atlantics Championship season opener, earned her first win in the Champ Car developmental series.

Less than 24 hours after Danica Patrick became the first woman to win an IndyCar race, the 19-year-old De Silvestro joined Katherine Legge as the only female winners in Atlantics.

Legge, who went on to drive two years in Champ Car, won three times in 2005, including a victory at Long Beach.

“Danica wins, I win, it’s a perfect weekend,” the Swiss driver said with a grin.

De Silvestro, whose best previous finish in 12 Atlantic starts last year was seventh, took advantage of a mistake by pole-winner Jonathan Bomarito in Sunday’s 38-lap event on the streets of downtown Long Beach.

Bomarito pulled away from the field at the start and built a lead of more than 7.5 seconds before he spun on lap 23 while all alone on the track. By the time the driver from Monterey, Calif., got going again, De Silvestro and several others had driven past.

Ochoa stretches win streak to four

REUNION, Fla. — Lorena Ochoa became the first LPGA Tour player in 45 years to win four tournaments in consecutive weeks.

Ochoa shot a 3-under 69 in the final round of the Ginn Open and beat rookie Yani Tseng by three strokes for her fifth victory in six starts this year.

Ochoa trailed early in the final round, but went ahead for good with three straight birdies beginning at No. 8. She finished at 19 under and became the second player to win four times in four consecutive weeks.

Mickey Wright did it in 1962 and 1963. Kathy Whitworth (1969) and Annika Sorenstam (2001) also won four consecutive events, but there were off weeks during their runs.

Sorenstam (2004-05) and Nancy Lopez (1978) hold the tour record with five straight victories in events entered, but neither of those came in consecutive weeks.

Weekly wins again at Hilton Head

HILTON HEAD ISLAND, S.C. — Boo Weekley won the Verizon Heritage for the second straight year, closing with an even-par 71 for a three-stroke victory over Anthony Kim and Aaron Baddeley.

Last year, Weekley needed chip-ins on the 71st and 72nd holes to beat Ernie Els by a stroke on a Monday for his first PGA Tour victory. On Sunday, Weekley strode up the 18th fairway with the win very much in hand and the gallery chanting, “Boooo! Boooo!”

Weekley finished at 15 under. He earned $990,000, and a second straight invitation to the Masters. He tied for 20th at Augusta National to miss qualifying for 2009.

Kim and Baddeley also finished with 71s, Jim Furyk (69) finished fourth at 11 under.

Watson repeats as champion

LUTZ, Fla.  — Tom Watson defended his Outback Steakhouse Pro-Am title, saving bogey after hitting into the water on No. 18 for a 1-under 70 and a one-stroke victory over Jay Haas and Scott Hoch.

A year after ending an 0-for-93 Florida drought at the TPC Tampa Bay, Watson finished at 9 under for his 50th title on the Champions and PGA tours.

Federer gets first title of season

OEIRAS, Portugal — Roger Federer captured his 54th career title, winning the Estoril Open when second-seeded Nikolay Davydenko retired with a left leg injury while trailing 7-6 (5), 1-2.

Federer returned to his winning ways in his fifth tournament of the season. It had been eight years since Federer had needed so many events to reach a final. He won despite windy conditions and the fact that he was playing on his most challenging surface.

Williams gets victory on clay

CHARLESTON, S.C. — Serena Williams captured the Family Circle Cup title, defeating Vera Zvonareva 6-4, 3-6, 6-3 for her first clay court title since the 2002 French Open.

Williams’ third title of the year was expected to lift her to No. 6 in the rankings. She won earlier in Bangalore and Miami. She is 19-1 in matches this year after winning her 31st career title on the green clay here on a breezy, overcast afternoon.

Blake upset in championship match

HOUSTON — Marcel Granollers-Pujol upset top-seeded James Blake 6-4, 1-6, 7-5 in the U.S. Men’s Clay Court Championship for his first tour title.

The seventh-seeded Spaniard came back from 3-0 down in the third set, turning back the American who at one point won 18 of 19 points.

Blue Jays release Frank Thomas

TORONTO — Slumping designated hitter Frank Thomas was released Sunday by the Blue Jays, who cut the 19-year veteran one day after he became angry for being taken out of the lineup.

General manager J.P. Ricciardi said he and Thomas came to “a mutual agreement” after meeting in the clubhouse early Sunday.

The move leaves the Blue Jays on the hook for $7,081,967, the remainder of his $8 million salary this year in the $18.12 million, two-year contract the 39-year-old Thomas signed in November 2006.

Manning marries college sweetheart

NEW YORK — A Super Bowl championship isn’t the only big event this year for New York Giants quarterback Eli Manning.

Manning married college sweetheart Abby McGrew during a sunset ceremony Saturday at the One & Only Palmilla resort on Mexico’s Baja Peninsula.

Manning, 27, and McGrew, 24, smiled and giggled during the 16-minute ceremony. They stood on a platform in the sand as waves crashed on the rocks behind them.

Manning and McGrew met as students at the University of Mississippi. Manning popped the question to her during a date in Hoboken last March, and they chose the resort for their wedding after vacationing there several times, The Daily News reported.
