Davis Aydelotte Robertson (September 25, 1889 – November 5, 1970)

Is this Hilltop Park?

Hit in 25 games in 1912, fielded in 20, for the Highlanders.

The plate states Morgan, the text states Milan.. which is correct?

I can't find any Clyde Morgan who played professional baseball during the 1910s, so that's Bain naming error. Clyde Milan (1887-1953) was born Jesse Clyde Milan, but later dropped his first name. His nickname was "Deerfoot." He was an outfielder for the Washington Senators throughout his playing career, from 1907 through 1922. During his final year he was a player-manager. He was also manager of the Senators in 1928, 1929, and from 1938 until his death. When not managing the Senators he managed minor league teams. He had a younger brother named Horace Milan who played for the Senators in 1915 and 1917. Clyde Milan player page at Baseball Reference.

The lines around his eyes :)

Trust the corrected caption, not the photo. As LC mentioned on this other photo (and in the notes section here), a group of baseball historians reviewed these images and corrected the names.

This is easily verified as Clyde Milan, for whom amny good photos can be found.
