Zach Jensen, RHP
Drafted in the 6th round out of Wake Forest in 1903, his potential really shot up after the draft leading to three Pitcher of the Year Awards. He also went to 6 All-Star games and helped the Royals win the 1912 World Series. He was named the 1908 AL Division Series MVP and spent his entire 16 year career with the Royals, staying healthy with the exception of a few weeks worth of injuries. He slots in very solidly behind J.P. Avila as the second best pitcher ever to play the game.

Elijah Turner, LHP
Turner is right on the cusp of the Hall of Fame by JAWS, but the absence of awards and his total career WAR keep him out. He did have a good peak and kept up solid above average contribution for 13 years. He was drafted in the 4th round of the 1903 draft out of Kansas.

Dean Davidson, LHP
Davidson may have had a chance at a Hall of Fame career but his talent level dropped sharply once he turned 30. He made 3 all-star teams and was the 1916 NL Division Series MVP, and finished in the top 3 Pitcher of the Year voting three times. He was drafted in the 9th round out of Springfield High School in Oregon.

He was part of the 1906 Dodgers Championship team in his rookie season. 1909 was his career year with 6.8 WAR, but he wasn't able to keep it all together for the long term.
Career Stats: 1916.3 IP, 505 BB, 858 K, 2.56 FIP, 96 FIP-, 29.0 WAR, 31.9 JAWS
Fabian Ricci, LHP
Ricci was one of the top closers in the game for many years - 7 all-star teams, a reliever of the year, and a World Series Championship all on his resume. The Brewers drafted him in the 3rd round of the 1904 draft out of Holy Cross.

Lütfü Wohlfarth, 1B
Wohlfarth was one of the first players to 2,000 career hits, but he never provided a ton of value at 1B. His offense was above average, but his defense was so atrocious it wiped out everything that the offense provided. He won three silver sluggers and helped the Red Sox win the 1905 World Series as the AL Division Series MVP. He currently holds the record for most career RBI - 960.
