Unheralded Teammates from 19th Century

Two of the pitchers with the best career winning percentages, as well as two of the best combination pitchers-position players, were teammates from 1884-91. Bob Caruthers was 216-89 for those years (1884-87 with St Louis Browns, 1888-91 with Brooklyn (Bride)Grooms). Dave Foutz was 134-58 for a combined 350-147.

Their records and the team's record year-by-year:
1884: Caruthers 7-2, Foutz 15-6, combined 22-8, team 67-40 (rest of team 45-32)
1885: Caruthers 40-13, Foutz 33-14, combined 73-27, team 79-33 (rest of team 6-6)
1886: Caruthers 30-14, Foutz 41-16, combined 71-30, team 93-46 (rest of team 22-16)
1887: Caruthers 29-9, Foutz 25-12, combined 54-21, team 95-50 (rest of team 41-29)
1888: Caruthers 29-15, Foutz 12-7, combined 41-22, team 88-52 (rest of team 47-30)
1889: Caruthers 40-11, Foutz 3-0, combined 43-11, team 93-44 (rest of team 50-33)
1890: Caruthers 23-11, Foutz 2-1, combined 25-12, team 86-43 (rest of team 61-31)
1891: Caruthers 18-14, Foutz 3-2, combined 21-16, team 61-76 (rest of team 40-60)

Not only that, but check out these batting records:

In 1886 (after leading the league in wins, winning pct., and ERA the year before), when he went 30-14, Caruthers also batted .334 (4th in league) in 87 games, led the league with a .448 on base pct., and slugged .527 (2nd in league) with 14 triples and 91 runs scored.
In 1887, when he went 29-9, Caruthers batted .357 (5th) in 98 games, .463 OBP (3rd), .547 slugging (2nd), 8 homers (4th), with 102 runs and 73 RBIs.

In 1887 (after leading the league in wins, winning pct., and ERA the year before), when he went 25-12, Foutz batted .357 (6th) in 102 games, with a .508 slugging (7th)and 108 RBIs (4th)
In 1888, while he was pitching less (12-7), he became a full-time player, batting .277 in 140 games with 13 triples (5th), 91 runs and 99 RBIs (3rd).

I find these stats astounding, and particularly astounding that the two were teammates throughout these years.

They were different, too: Caruthers was only 20 when he came up; his arm apparently gave out at age 28, after which he tried one more brief go as aan outfielder before retiring at 29. Foutz, on the other hadn, was already 27 when he broke in, and ended up mainly as a position palyer and spot pitcher from age 32-39, with the exception of age 35, when he came back as a part-time starting pitcher to go 13-8 (a year when he batted like a pitcher, too, only .186).

Caruthers finished with a .282 batting average in 2465 AB;
Foutz retired with a .276 batting average in 4533 AB.
