Aaron Boone no longer has to worry about being fired ... so says Yanks legend Tino Martinez, who tells TMZ Sports NY's latest surge is more than enough to keep the manager safe.
"I think he's done a great job," Martinez said out in NYC this week. "He's great for the team, the organization -- so I think he deserves to be here as long as he wants."
Of course, Yankees fans and perhaps even ex-NY players didn't always feel that way this season ... 'cause for a while, the Pinstripes were REALLY struggling under Boone.
But, the Yankees have turned the ship around in a big way -- winning 11 in a row ... and vaulting to just 4 games out of first place in the AL East.
Martinez says it's all been impressive to watch ... and should keep Boone around well into next season and beyond.
"The ups and downs of a season make a great manager," Tino told us, "and he's been even keeled the whole time."
For as good as Boone has been in turning around the Yankees ... Martinez clearly feels the manager owes Anthony Rizzo a bit of praise for the recent win streak as well.
Tino tells us the first baseman "changed the culture of the team" after his trade from Chicago to New York -- and is "one of the best ever."
By the way, we also asked Tino about next year's Field of Dreams game ... and while he's clearly in favor of a Sandlot-style replica game, ya gotta hear why he thinks that's just not a feasible option.
