According to Baseball Library:

Jun 23, 1909 - At the Polo Grounds‚ Christy Mathewson wins a doubleheader against Boston. Matty relieves Marquard in the opener with the score tied 4-4 in the 9th. After shutting down Boston‚ the Giants score a run for the 5-4 win. Matty then coasts in the nitecap to an 11-1 win. Mathewson leaves after two innings with a 4-1 lead‚ and Doc Crandall operates the rest of the way‚ The official scorer awards the game to Christy‚

Jun 22, 1909 - Christy Mathewson pitches 4 innings for the Bucknell alumni against the varsity‚ as the undergrads win‚ 13-12. Matty also plays 3B and chips in with 3 hits.

The back of the photo has a 1909 date.

My guess now is that this photo is from that alumni game June 22, which since there was a double header at the Polo Grounds June 23, had to have been played at the very same ballpark for timing purposes. How could the Giants have played a doubleheader on June 23 at the Polo Grounds, having been all the way in Lewisburg, PA (3 hours by car today) just the day before?

I know Matty looks young in that photo, but it seems to explain alot, including the older, faded B sweater...isn't it at all possible that he's just wearing a Bucknell away uniform representing the Alumni (possibly his own), and the varsity team is wearing the home unis?

May not explain why he's wearing a sweater in June though.
