Miserable Ike’s misplay seals Reds sweep of Mets

The only thing missing was Elvis Presley’s soundtrack “Viva Las Vegas” blaring in the background as Ike Davis tried to wish foul Brandon Phillips’ chopper in yesterday’s ninth inning.

The beleaguered Mets first baseman watched the ball hop past him, placing a cherry atop the cow pie that has been his 2013 season. The only reasonable assumption after the Mets’ 7-4 loss to the Reds at Citi Field is Davis’ demotion to Triple-A Las Vegas is imminent.

For now, Davis remains on double-secret probation. A club official said Davis likely still will be on the 25-man roster tomorrow, when the Mets open a three-game series against the Braves, but he could be demoted soon afterward if no improvement is seen.

“I think we’ll have a better understanding over the weekend,” the official said.

With runners on the corners and one out in a 4-4 game in the ninth, Phillips’ two-hopper bounded over first base as Davis tried to argue the ball was foul. Shin-Soo Choo scored the go-ahead run before two more scored on Todd Frazier’s single to center against Bobby Parnell.

Davis said he was inclined to let the ball go foul because there wasn’t enough time to nail Choo at the plate, and a throw to second for a double play attempt would have entailed a tag, which would have allowed Choo to score before the final out was recorded on the relay.

“It’s in my head that was the right play to do and it didn’t happen to go my way,” Davis said. “If I catch the ball, we’re not turning two and we’re not getting the guy at home. I guess we could have turned two, but the guy would have still scored. I thought if I let it go, it would be obvious that it was foul.”

Davis went 0-for-2 at the plate with two walks and watched his batting average drop to .147. In his past 38 at-bats he only has one hit.

Two days earlier, Davis was called for interference on a play against the Reds. He also committed an error last weekend at Wrigley Field and watched a playable Ruben Tejada one-hop throw bounce past him in the same series.

Manager Terry Collins said he recently spoke to Davis about not letting his offensive struggles carry over to defense.

“It was addressed before today, so I do not think it’s part of what’s going on,” Collins said. “When you’re as good as he is and you go through a tough spell, the ball in Chicago, which he usually gobbles up, the ball today, it’s just so not him that it’s easy to think he’s taking his offense into the field, but I don’t think that’s the case.”

Davis’ teammates are rooting for the popular first baseman to recover, but it might be too late.

“It’s one of those stretches, you wish that on nobody,” David Wright said.

The Mets (17-27) were swept three games by the Reds and fell 10 games below .500 for the first time this season on a day Matt Harvey didn’t have his best stuff.

Harvey allowed a season-high four earned runs on nine hits with three walks and six strikeouts over 6 1/3 innings in receiving a no-decision. It marked just the third time this season Harvey failed to complete seven innings.

With Harvey at 100 pitches entering the seventh, Collins stuck with his ace and watched the Reds get three straight singles, the last of which was delivered by Phillips and put the Mets in a 3-2 hole. Jay Bruce’s ensuing RBI groundout against Scott Rice was the final run charged to Harvey.

Joey Votto hit a two-run homer in the third, giving the Reds a 2-1 lead.

“We can’t get caught up in what the record is,” Collins said. “We’ve got to get caught up in playing the game right. If you dig your way out of it, it really doesn’t matter if you’re eight or nine or 10 [games below .500].”
