Photo from the January 6th, 1901, edition of El Score, a Havana publication, during the visit of major league players from the Dodgers and Giants (and a few extras) to Cuba

The photo caption does not include identifications, so this is my attempt at IDs based on who is known to have gone on the trip:
Top Row (L-R): possibly Jesse Tannehill, Willie Keeler, possibly Bill Dahlen, William (Pop) Schriver, possibly Jimmy (Doc) Casey, Hugh Jennings, Jimmy Callahan.
Second Row (L-R): Jimmy Sheckard, John (Shad) Barry.
Third Row (L-R): Possibly Bill Donovan (Brooklyn uniform), Jack Doyle (dark sweater), Win Mercer (New York uniform), Tom Daly (Brooklyn uniform, far right).
Fourth Row (L-R): Tommy Simpson (Manager of the tour, wearing a suit), possibly Frank Bowerman.
Fifth Row (L-R): George Davis, Kid Gleason.
Bottom Row (L-R): Mike Grady, Charlie Hickman.
Others on the tour were Harry Howell, Elmer Foster, Cy Seymour, and Tom O'Brien. I am certain that O'Brien is not in the photo, because he became seriously ill on the cruise south to Cuba and did not play at all; he died before the following season began.
