Thus the sliding player must be in a road uniform. The Tigers had dark caps with their gray road uniforms from 1907 forward, and in Cobb's first two seasons (1905 and 1906), the road uniforms were dark blue. The only two American League teams whose light-colored road uniforms had light-colored caps with dark piping in the years 1907 through 1912 were St. Louis (1907 and 1910-1912) and Washington (1910 and 1911 only).

Based on the images from the HOF Dressed to the Nines uniform database, I'm fairly certain the year the picture was taken is 1910, with the White Sox in their home whites and the St. Louis Browns in their away greys with narrow pinstriping (and with the fleur-de-lis on the arm as judsonhamlin noted).

The Browns played a total of 11 games in Chicago that season according to baseballreference.com, and Sullivan was the catcher in only 5 of them.

April 14 - Fred Payne caught
April 15 - Payne
July 1 - Billy Sullivan caught
July 2 - Payne
July 3 Game 1 - Payne, Game 2 - Bruno Block caught
July 4 Game 1 and 2 - Sullivan
July 5 - Sullivan
September 13 - Sullivan
September 14 - Payne

On 7/1 in a 2-0 win, 6 men reached base for the Browns: George Stone, Roy Hartzell, Bobby Wallace, Pat Newnam, Al Schweitzer, and Frank Truesdale. Stone and Truesdale each scored.

In a 5-3 loss in Game 1 of the 7/4 doubleheader, Stone, Hartzell, Wallace, Newnam, Schweitzer, Danny Hoffman, Truesdale, Dode Criss, and Bob Spade reached base. Stone, Hartzell and Spade scored.

In Game 2 (a 7-4 loss), Stone, Hartzell, Wallace, Newnam, Schweitzer, Hoffman, and Truesdale reached, with Stone, Hartzell, Wallace and Newnam scoring.

On 7/5 in a 6-5 win, Hartzell, Wallace, Newnam, Schweitzer, Art Griggs, Hoffman, Truesdale, Killefer, Criss, Barney Pelty, and Joe Lake all reached base. Wallace, Newnam, Schweitzer, Hoffman, Truesdale and Killefer all scored.

And finally on 9/13 in a 1-0 shutout win, only Red Corriden, Hub Northen, Killefer and Red Nelson reached, with Corriden scoring the lone run.

I know that it probably doesn't help much, but hopefully this info can be of some use in identifying the sliding player on the T202 card. If someone can go into the newspaper archives to find accounts of each game, perhaps more clues could be uncovered.
