Ike Davis received zero bang for his buck yesterday.

After spending $1,470 on six tickets for family members, the Mets first baseman struck out four times and finished 0-for-5 in his team’s 11-2 victory over the Padres at Citi Field.

In three career Opening Day appearances, Davis is 0-for-12 with seven strikeouts.

“The streak continues,” Davis said. “Maybe I’m nervous or jitters or swinging too hard. I still have never gotten a hit on Opening Day.”

Davis grounded out in the third inning and whiffed in the first, fourth, sixth and seventh innings.

“Honestly, it’s not a bad day to do it, because they didn’t need my help at all,” Davis said. “But I can help out the next game and actually do something at the plate.”

Davis said the Padres bombarded him with offspeed pitches, none of which were over the middle of the plate.

* Johan Santana, Frank Francisco, Jenrry Mejia and Shaun Marcum were all placed on the 15-day disabled list to create roster space. Marcum’s placement was retroactive to March 22, which would allow him to start Sunday against the Marlins at Citi Field.

Marcum, who is recovering from neck stiffness, is scheduled to throw five 15-pitch innings today at the Mets’ complex in Port St. Lucie, Fla.

* Manager Terry Collins said he does not have one reliever in mind for the eighth inning to set up Bobby Parnell.

“It’s going to be a mix and match for awhile, until we get a feel for one or two guys,” Collins said. “That’s part of the game where it would be nice to have one guy.”
