Of course, the superstar pitcher is still a member of Toronto's squad, and he says he's "focused on my time with the Blues Jays now."

But, with the Yanks reportedly interested in the 28-year-old NY native ... he made it clear to our camera guy before hittin' the Blue Jays team bus Wednesday -- he'd be fine with the move!!

Stroman has previously hinted he's down to rock the pinstripes ... telling a group of reporters earlier this week that he's "built for the bright lights."

Unclear what the Yankees are willing to offer for Stroman -- who has a 3.04 ERA and 77 strikeouts in 17 starts this season -- but they do desperately need a starting pitcher for the second half of the season.

Could Stroman's clear willingness to be a Yankee help move trade talks along??
