ATLANTA — Ivan Nova combined with four relievers on a five-hitter and the New York Yankees beat the Atlanta Braves 3-0 on Monday night to claim a share of first place in the AL East for the first time in seven weeks. Raul Ibanez led off the second inning with a homer and Robinson Cano had two hits, including a run-scoring single in the first. The surging Yankees climbed into a tie with idle Tampa Bay for the division lead, their first return to first place since April 24.
