The same photo, cropped a little differently, is featured on the cover of Brian Podoll's book The Minor League Milwaukee Brewers, 1859-1952.
The goat mascot, sometimes called "Woozy" but propertly named "Fatima" was presented by the club by the Milwaukee Journal in 1912. He lasted with the club at least as long as 1914, by which time he had taken up a summer job cutting the grass at Athletic Park.
I think the image is greatly enhanced by the presence of the fans in the background, and when you can see the wooden slats on the top of the dugout.

Podoll identifies the players this way:
Back row: Hap Felsch, OF(?); Cy Slapnicka, P; Newt Randall, OF; Johnny Hughes, C; Phil Lewis, SS; unknown. Sitting: Ralph Cutting, P; Buster Braun(?), P; Cy Young(?), P; Tom Jones, 1B; Harry "Pep" Clark, manager/3B; Tom Dougherty, P; unknown; Jap Barbeau(?). On ground: Lena Blackburne, IF; Joe Berg(?), IF; Joe Hovlik, P (with goat).But, as Borchert Field contributor Dennis Pajot reminds me, Rex Hamann and Bob Koehler's wonderful book "The American Association Milwaukee Brewers" identifies them this way:
Standing: Jimmy Block, Rube Nicholson, Newt Randall, Johnny Hughes, Phil Lewis, Doc WatsonObviously, this warrants further investigation.
Seated: Larry Gilbert, Buster Braun, Cy Slapnicka, Tom Jones, Harry Clark, Tom Dougherty, Joe Berg, Doc Marshall Reclining: Ralph Cutting, Larry Chappelle, Joe Hovlik
