This pick reeks of homerism, but when your great uncle is in the Baseball Hall of Fame and you don't pick him, there will be trouble at the dinner table.
So for my last pick, and my team's namesake I give you, my uncle:
Walter James Vincent "Rabbit" Maranville - SS/2B
Rabbit will not be asked to hit much, although he is 19th All-Time in Triples (177) and 11th All-Time in Sac Hits (300), but this pick is all about defense. Maranville stands first among all shortstops in putouts (5,139), third in assists (7,354), and second in total chances (13,124). He was also a top fielder at second base.
Nicknamed for his speed and rabbit-like leaps, he was always a superior fielder, famous for his unique basket catch of high infield flies. Consistency was his hallmark and greatest virtue. During his first tour with Boston, he led NL shortstops in putouts each year from 1914 to 1919 (except for 1918, which he spent in the Navy), assists twice, double plays three times, and fielding average once.
23 total seasons in baseball, all the while fighting alcohol and a stint in the Navy. (Side note: he got a 10 day pass from the Navy in 1918 where he played 11 games and hit 0.318. before going back to sea.)
