Nemec went on to write in The Beer & Whiskey League that "Tucker was a real rarity in his day, a switch-hitter. One of the first of note, Tucker confounded Tony Mullane, who was even more of a rarity-a switch-pitcher. Although normally a righthander, Mullane could throw effectively with either arm. Since many players in the mid-1880's still did not use gloves in the field, Mullane would sometimes hide his hands behind his back as he began his delivery, keeping a batter guessing until the last instant as to which arm would launch the ball. But Tucker had the weapon to thwart Mullane. Inasmuch as the rules in 1887 permitted a hitter to jump from one batter's box to another at will, Tucker was free to leap to the opposite side of the plate as soon as he saw which arm Mullane would pitch."
I'm not sure if it has anything to do with the switch-hitting but Tucker finished in the top ten in hit by pitches every year he was in the majors except for 1899, his final season. He finished first in HBP five times and four straight years from 1889-1892. From 1887 to 1895, Tucker never finished worse than fourth in HBP. He is third on the all-time list behind Hughie Jennings and Craig Biggio.
In The National Game, Al Spink wrote:
Tom Tucker of the Baltimore team was one of the finest fielders of the first basemen who flourished in the early nineties.
Tom was also an excellent batsman and base runner.
He was a left-handed hitter and often came to the rescue of his side with a good stroke.
Tucker is now living in retirement at Holyoke, Mass., where also are "Smiling" Mickey Welch of the old New York champions, "Jack" Doyle and Jack Hanifin of the Boston Nationals.
