Alex Rodriguez insisted yesterday he is not finished.

In fact, when he held the bat in his hand during the first day of his return to baseball activities and took about 30 swings off a tee, he said: “Man, I’m so excited to be back out there. It was like being 8 years old again when I first grabbed a bat. I’m really looking forward to getting back.’’

This is now about “unfinished business.’’

When Rodriguez will take care of that business remains to be seen. That is the $114 million question. There has been much talk about him returning to the Yankees after the All-Star break.

When I pressed him about returning this year — asking: Will you definitely be back this season? — Rodriguez answered: “I really hope so, I really hope so. That is [as] specific as I’ll get. … I’m working 24/7 to get back on the field. The way the season ended last year was very embarrassing. It was very tough on me and obviously our team; it was a devastating sweep against Detroit [in the 2012 ALCS].

“I have a lot of unfinished business and I’m looking forward to getting back and helping my team win. I’m really looking forward to getting back on the field where I am close to 100 percent and being who I am.’’

Just who is Alex Rodriguez now at the age of 37 after so much shadow and success in his baseball life and after this latest extensive hip surgery in mid-January?

“It’s been a rough stretch with the rehab,’’ he said. “I’ve been through it before in ’09 but obviously this one was a lot deeper, a lot more severe, it was five anchors and it shaved the bone, they didn’t do any of that in ’09.’’

A-Rod is not putting a timetable on his return, noting, “That’s wise around here these days.’’

This was only the first day of light baseball activity in a long road back. He ran a little, threw a little and took those “30 hacks.’’
