Cincinnati ? Two games, two grand slams. Carlos Beltran has started a very rare streak.

Beltran hit the last of New York’s three homers Tuesday night, a seventh-inning grand slam off Eric Milton that powered the Mets to an 8-3 victory over the Cincinnati Reds.

Beltran’s slam off Milton (6-5) was the sixth of his career and his second in two games. He and Cliff Floyd connected Sunday during a club-record 11-run sixth inning that set up a 13-7 win against the Cubs at Wrigley Field.

He became the 23rd major leaguer to hit grand slams in consecutive games. David Eckstein was the last to do it, for the Angels in April 2002.

“That’s baseball,” Beltran said. “Some days you feel good, some days you feel not so good.”

The Mets have won five of their last six games, improving the NL’s best record to 56-37.
