J.D. Martinez laughs at the idea that, only a few weeks after his 30th birthday, he’s one of the veterans on the Diamondbacks’ roster. But it’s also one of the things he likes most about his new team – and one of the reasons he says he’d love to be able to remain with the Diamondbacks beyond this season.

“I’ve thought about it a lot,” Martinez, a free agent at the end of the season, told azcentral Sports. “It’s definitely something I’d love, I’d be interested in. I’ve loved my time here. The guys are great. The team is young. They’re definitely going to be good for a while.”

Martinez’s impact during his seven weeks with the Diamondbacks was enormous even before his monumental performance on Monday night, when he became just the 18th player in baseball history to hit four home runs in a game.

For the past four years, Martinez has been one of the game’s more dangerous hitters. He figures to command a monster contract when he hits free agency this offseason, and his price tag seems to be going up by the day; his four home runs on Monday gave him 18 in 144 at-bats since the trade.

When the Diamondbacks landed him in a July 18 trade with the Detroit Tigers, the assumption was they were acquiring a pure rental bat. That still seems likely to be the case, but when speaking with reporters last week, General Manager Mike Hazen left open the possibility of bringing Martinez back.

And from Martinez’s perspective, the Diamondbacks satisfy a primary requirement of his impending free-agent search.

“I think one of the most important things in my free agency is I want to be on a team that’s relevant – a team that’s good, a team that’s in it,” he said. “I don’t want to be on a team just because (they offer the most money). I want to be on a team that’s got a chance. That’s what’s fun. That’s what you play the game for.”
