[2] After the war, Patrick had high expectations for his son, and the two frequently fought over Tim's pursuit of baseball.

[1] Keefe's early professional career included minor league stints in Lewiston, Clinton, New Bedford, Utica, and Albany.

He immediately established himself as a talented pitcher, posting an astounding 0.86 ERA in 105 innings pitched, a record that still stands.

In 1883, after the Trojans folded, Keefe rose to stardom with the New York Metropolitans of the American Association under manager "Gentleman" Jim Mutrie and had one of the most dominating seasons in baseball's early history.

On July 4 of that year, Keefe pitched both ends of a doubleheader against Columbus, winning the first game with a one-hitter; the second a two-hit gem.

Here, Keefe joined future Hall of Famers Buck Ewing, Monte Ward, Roger Connor, Mickey Welch, and "Orator" Jim O'Rourke to form an outstanding team that finished with a fine 85–27 record.

In 1887, Keefe sat out several weeks of the season after he struck a batter in the head with a pitch; he was said to have suffered a nervous breakdown.

[4] He had arguably his greatest season in 1888, when he led the league with a 35–12 record, 1.74 ERA and 335 strikeouts (see Triple Crown).

The Giants played the St. Louis Browns of the American Association in a postseason series for the Dauvray Cup, and Keefe added four more wins to his tally.

Keefe transferred ownership of his real estate assets to his mother so that they would remain safe from any legal rulings.

[5] In the 1891 preseason, Keefe refused a salary offer of $3,000 from New York; he had earned $4,500 in the previous season.

[9] Late in his playing career, Keefe began to coach college baseball and he continued in this capacity after his retirement as a player.
