Dimag, Lazzeri, Crosetti and who are these other guys?
 

Can anyone identify the three other guys chowing down and the guy in the wife beater?

I think I've got it. The guy standing at Lazzeri's left shoulder appears to be famous clubhouse attendant Pete Sheehy. Between Sheehy and DiMaggio is Del Webb, Yankees co-owner. Between DiMaggio and Crosetti is other co-owner Larry MacPhail. The wife beater guy? Not a clue, sorry.

Jonathan, I too was thinking that could be Sheehy but Webb and MacPhail didn't buy the Yanks until the mid-forties. This image has to be 1936 or 1937. Lazzeri was gone after that.

EDIT: On second thought, based on that time line, Sheehy would have only been 26 or 27 years old (died in 1985 at 75 years of age) - I think the guy in the picture is older. Maybe a young George Weiss who was working in the Yankee system at that time and would have been 42-43 years old.

Well I feel dumb! Of course, too early for those guys. I think you might be onto something with George Weiss though. He bears a resemblance to MacPhail. I still think that's Sheehy though, but (obviously, as history has shown) I could be wrong...
