The rearranged deck chairs on the Titanic were a sight to behold yesterday with Rick Ankiel’s addition to the Mets, but this ship is still headed toward the bottom of the Atlantic.

Or at least for now, the Mississippi.

With Ankiel in the lineup and playing center field only hours after signing with the team, the Mets mustered all of four hits — and only one after the second inning — in a 6-3 loss to the Cardinals at Busch Stadium.

The Mets (14-21) lost their fourth straight and made it seven consecutive games with three runs or fewer. Ankiel finished 0-for-3 in his Mets debut with two strikeouts and a walk.

The 33-year-old, whom the Astros released last week, is expected to share center-field duties with Juan Lagares, but the Mets have problems that go beyond their broken outfield.

The bullpen remains among those concerns after Scott Atchison surrendered a two-run homer to Matt Holliday in the seventh that gave the Cardinals a 6-3 lead and all but doomed the Mets. The go-ahead run had scored against Scott Rice (1-3) earlier in the inning.

“It was the right guys to be out there, it’s just we didn’t get it done,” manager Terry Collins said.

The go-ahead run in the seventh scored on a freak play: Matt Carpenter hit a shot off Rice’s foot that caromed into foul territory on the first-base side. John Buck retrieved the ball, but with nobody covering the plate, Ty Wigginton raced home from second to give the Cardinals a 4-3 lead.

Rice said he was trying to make a kick save on the play with the intention of deflecting the ball to an infielder.
