The Mets are hoping Ike Davis’ demotion solves his hitting woes. But, in the short term, there are many questions to answer. Here are four regarding his demotion: Davis’ plan is pretty simple. “I’m going to go down and work hard and figure out my swing,” Davis told The Post yesterday. He is expected to make his Las Vegas debut tonight. The organization has to be happy to hear Davis’ attitude. But how will Davis and the Triple-A staff rediscover his swing? Alderson, in a phone interview yesterday, said he is mainly leaving the hitting mechanics to the minor league staff, because Vegas hitting coach George Greer and roving hitting instructor Lamar Johnson have a relationship with Davis from when the first baseman played in the minors. Alderson also said Mets hitting coach Dave Hudgens will likely give Greer his input. “In some ways, it’s not about new ideas,” Alderson said. “It’s about the application of existing ideas, and in that environment it may be easier to apply those ideas than it had been here where the pressure on outcome and results is so much greater.” Vegas manager Wally Backman said he wants to get Davis back to the form he had when he first joined the Mets. “We’ve watched hours and hours of tape on him, back when he first went to the big leagues from the minor leagues,” said Backman, who added Davis needs to improve his pitch selection. “He’s made so many changes. I think personally, it’s been too many changes. We’ll try to get him back to what he did to get to the big leagues.” He wasn’t ready to put a timetable on Davis’ stay. “It’s not going to be, ‘Hey, if you get 15 hits this week, you’re gone,’ ” Backman said. “We’ve got to see you do this consistently. … It may be two weeks. It could be a month. I don’t know.”
