Matt - a correction to Seifried:
He won 3 BOTY awards - 1908, 1910 and 1911. He's the first AL player to win three BOTY (Fabian Allen in the NL was the first), and he was the first player in TWB to win consecutive BOTY.
Here's a trio of pieces out of Time Warp history on Seifried:
1914:
"The Federal League began play this season, hoping to create a third major league. In doing so, several players were raided from the National and American Leagues. Every player who jumped to the Federal League was black listed from the NL and AL. Here is a list of the more well-known players who left for the Federal League:
Jean-Pierre Stepro, 1B, Boston Red Sox
Patrick Seifried, 1B, Cleveland Broncos (3-time POTY)
Harry Harvey, LF, St. Louis Cardinals
Floyd Kubitzki, SS, Washington Senators
Jesse Whitfield, SP, New York Yankees

1916:
"The American and National Leagues came to a peace agreement with the Federal League. Part of that agreement allowed several Federal League players to rejoin the NL and AL as free agents. The most notable name was first baseman Patrick Seifried, who signed with the offensively-starved Yankees. Seifried made a name for himself as a big hitter in the Federal League just as he had with Cleveland."
1924/25 Off Season:
"Patrick Seifried, 1B, Cleveland Blues 1906-1913, New York Yankees 1916-1924
Seifried began his career as a big young talent for Cleveland's growing dynasty. He left the team after the 1913 season to play in the now-defunct Federal League for two seasons. He was black-balled for leaving, but after the league folded, he was allowed to return. He signed with Cleveland's main nemesis, the Yankees. There he continued his great career, but never did he taste World Series victory. He retired with a .327 average (10th All-Time), 2720 hits (9th All-Time), 1195 RBI (6th All-Time), 1348 runs (6th All-Time) and 1137 walks (4th All-Time). In Cleveland he was part of one of the best baserunning teams in history. He accumulated 303 triples (13th All-Time) and 235 stolen bases. He also won the 1910 and 1911 BOTY Awards, and he was awarded 6 Gold Gloves."
