PITTSBURGH -- Pittsburgh Pirates right fielder Gregory Polanco stepped into the batters box with the bases loaded and one out in the fourth inning. Zaza Pachulia Jersey . His team led the Miami Marlins by a run, and he had a golden opportunity to put the game out of reach. After taking two pitches out of the zone, he fouled one back behind the third-base dugout. The next was hit foul down the left field line. Polancos third cut did the trick as he laced left-hander Brian Flynns 2-2 offering to his opposite field for a two-run single that gave the Pirates a three-run lead. The rookie finished 2 for 4 and drove in four runs, Edinson Volquez pitched one-hit ball over seven innings, and Pittsburgh beat Miami 7-2 Thursday night. "I was just trying to see the ball and not hurry with my swing," Polanco said. "He was throwing really good. Thats why I was fouling off so many balls." Polanco is showing he can handle left-handers early in his big league career. "I think thats the third time hes shown that ability to hit a ball into left field off a left-hander," Pittsburgh manager Clint Hurdle said. "When theyre throwing down and away, he stayed out over the plate and covered it." Marlins reliever Dan Jennings was hit in the head by a line drive off the bat of Jordy Mercer in the seventh. Miami manager Mike Redmond said Jennings had his eyes open and was responding to questions when he was on the mound. After the game, the Marlins announced that a CT scan on Jennings was negative and that he was diagnosed with a concussion. He was kept in a hospital overnight for observation. Jennings momentarily stumbled before going to his knees after the play. He stood up to get in a cart and held up a hand to acknowledge the crowd as he was driven off the field. Volquez (9-7) didnt allow a hit until the fifth, when Donovan Solano singled with one out. Volquez struck out seven batters and walked three. Flynn (0-1) was chased before he got an out in the fifth. Mercers leadoff double started a three-run fourth. Polancos two-run single made it 3-0. Mercer and Gaby Sanchez added RBI singles in the fifth. Mercer finished with three hits and scored twice, and Josh Harrison extended his hitting streak to a career-high 11 games. Polanco hit a two-run double in the eighth. Giancarlo Stanton hit his 27th homer of the season, a two-run drive in the ninth for the Marlins. "Its just one of those nights," Redmond said. "Weve got to be able to swing with these guys and we werent able to do it." TRAINERS ROOM Marlins: 1B John Baker was held out of the game after fouling a ball off his foot Wednesday night.

Froch floored Groves with a huge right hook with about 30 seconds remaining in the round, with the referee immediately stopping one of most hyped fights in the countrys boxing history. He improved to 33-2, with 24 knockouts. "This is the greatest moment of my boxing career," Froch said. "Its the biggest event Ive been involved in." Groves (19-2, 15 KOs) had started slower but grew into the fight, only to be knocked down with Frochs biggest punch of the bout. "I feel like I let myself down," said Groves, who had vowed to send Froch into retirement with a victory. "Fair play, he got me with the punch." The rematch was ordered by the IBF after Frochs win in a controversial first fight in Manchester in November, when the referee stepped in too soon with Groves wobbling on his feet. This time, there were no complaints from Groves, who required treatment in his corner before going to congratulate Froch -- showing the bad blood between the pair that had dominated the build-up was over. Ed Macauley Jersey. The rematch was not as exciting as the first fight, with both boxers more restrained and seemingly intent on lasting the full distance. Froch -- arguably Britains top boxer for the last five years -- dominated the centre of the ring but only first connected with a left hand in the third round that rocked back Groves. Frochs punches were generally ragged and he walked into some punches by Groves in the sixth and seventh rounds. The ending was conclusive, though, with Froch swinging initially with his left and following it up with a massive right that left Groves in a heap on the canvas. "It was neck and neck, there was nothing in it," said Froch, who wants to crown his career with a fight in Las Vegas. "One punch was all the difference." The fight captured the public imagination, and was considered the biggest grudge match in British boxing since the days of the Nigel Benn-Chris Eubank rivalry in the early 1990s. ' ' '
