Nico Rosberg continued his fine start to the season by topping the timesheets in a Chinese GP first practice session that was disrupted by red flags and punctures. Colton Schmidt . The German has claimed victory in the first two races of the season, bringing his winning streak to five races, and beat team-mate Lewis Hamilton by just over a tenth of a second with a 1:38.037 in Shanghai on Friday morning.Ferraris Sebastian Vettel trailed the Mercedes duo in third, while Fernando Alonso made his return from injury to finish 12th in the McLaren. However, P1 was overshadowed by two red flags due to rear left tyre problems.First, Felipe Massa spun off at Turn Six after his tyre came loose, with debris flying off his Williams. Following heavy clean-up work on track and back in the garage the Brazilian returned later on in the session, only to face a failure on the same tyre, at the same corner.Moments later, Kevin Magnussen was also limping back to the pits with the same rear left tyre shredded. Pirelli insisted that Massas issues were not down to simple punctures, instead putting it down to air loss connected to technical trouble. They later confirmed that the Williams and Renault problems were not tyre related.While investigations will continue, McLaren engineers suspected that the Williams problem was due to the tyre rubbing against body work, with Magnussens down to debris on the track.Massa though, was uncertain. We had two punctures. Why? I dont know, he told Sky Sports F1. We are investigating. For sure, something is touching the tyre or the wheel or whatever.We had no idea why we had the first problem. We checked the car and it was ok. But then we had the same problem. Hamilton, who has been handed a five-place grid penalty for the race, set the early pace on the medium compound - two tenths faster than Rosberg.However, the world champion was reporting problems as he locked up and span off twice at Turn 11.Following the 30-minute stoppage due to the second red flag there was a flurry of activity at the end of the session, during which Rosberg edged ahead of his team-mate.Even Rosberg encountered issues towards the end of the session, which Mercedes diagnosed as an ignition problem.

The first baseman hit a two-run homer in the top of the ninth inning to lead the Mets to a thrilling come-from-behind 3-2 victory over the Milwaukee Brewers.NEW YORK, N.Y. - Tampa Bay Rays pitcher Alex Colome has been suspended for the first 50 games of the season for a positive steroids test. The 25-year-old right-hander tested positive for Boldenone, the commissioners office said Monday. Boldenone is used primarily for the treatment of horses. Colome was 1-1 with a 2.25 ERA in three midseason starts as a rookie last year. Colome was optioned March 8 to Triple-A Durham of the International League. "We were disappointed to learn of Alex Colomes violation of Major League Baseballs Joint Drug Prevention and Treatment Program," the Rays said in a statement. "We fully support Major League Baseballs policy and its efforts to eliminate performance-eenhancing substances from our game. Bob Young. quot; Colome, a native of the Dominican Republic, reached the majors for the first time last season, defeating the Miami Marlins in his debut on May 30. He was recalled again in June, making two starts against the New York Yankees and Detroit Tigers before hurting his pitching elbow. Colome was viewed as valuable rotation depth in light of an off-season elbow surgery that will keep right-hander Jeremy Hellickson out until May. He is the second player suspended this year under the big league drug program following Yankees third baseman Alex Rodriguez, who was banned for the entire season for violations of the drug agreement and labour contract.
