In 1907, Schmidt appeared in 104 games, 96 as the Tigers' starting catcher, and compiled a .244 batting average with six triples and eight stolen bases.
Defensively, he led the American League's catchers with 14 double plays turned, but also led the league with 34 errors at catcher and ranked second with 16 passed balls.

The Tigers won the American League pennant and lost to the Chicago Cubs in the 1907 World Series.
Schmidt hit .167 (two singles in 12 at bats) in the World Series, and his multiple defensive lapses in Game 1 were particularly costly.
In Game 1, the Cubs stole six bases on Schmidt.
And a poor throw to second base in the fourth inning failed to catch Frank Chance who was heading down the line when the batter swung and missed; an accurate throw would have ended the inning, and instead Chance scored on a base hit.
Even worse was a costly passed ball that cost the Tigers a victory.
The Tigers led in the ninth inning with two outs and Chicago's Harry Steinfeldt on third base; Chicago pinch hitter Del Howard swung on a third strike that should have ended the game, but "Schmidt missed the ball, which got by him to the crowd," allowing Steinfeldt to score the tying run.
After the game, the Detroit Free Press wrote: "The surprise of the game was the poor work of Charlie Schmidt, who had an off day such as probably will not come to him again in the series.
He found it almost impossible to locate second sack, and only once, in a half dozen tries, did he manage to put the ball where the infielder could get it on the runner."
Schmidt also appeared in Games 3 and 4, allowing two stolen bases in each game.

After the season, x-rays revealed a severe dislocation on the forefinger of Schmidt's throwing hand.
Doctors examining the injury questioned how it was possible that Schmidt had been able to play in the World Series at all.
The finger was broken in a game in mid-September; he underwent surgery in November to re-break the finger to allow it to heal properly.
