By PAUL NEWBERRY The Atlanta Braves worked to bolster their rotation, closing in Tuesday on a $60 million, four-year deal with Derek Lowe, according to a person familiar with the negotiations.Talks were continuing on final deal points and no letter of agreement had been signed, the person said, speaking on condition of anonymity because the contract had not been completed.Atlanta also finalized a three-year contract with Japanese all-star pitcher Kenshin Kawakami.A 14-game winner for the Dodgers in 2008, Lowe visited the Braves last week after longtime Atlanta pitcher John Smoltz agreed to a $5.5 million, one-year deal with the Boston Red Sox.Lowe, who also was sought by the rival New York Mets, would be a huge addition to a rotation devastated by injuries in 2008.
