Mark Perry, RHP
Perry's peak was at the beginning of his career, with three 6-WAR seasons from age 23-25. He held his value well throughout the years and settled in as a 3-4 WAR starter for the Giants. In 1965, he pitched for the Padres and stayed with that team for a few years before retiring.
Initial Acquisition: Drafted 37th overall in 1947 by the Giants out of Naples
MLB Awards: 1 J.P. Avila Award, 1 ROY, 3 AS, 1 WS
Career Stats: 3804.7 IP, 1174 BB, 2028 K, 3.68 FIP, 95 FIP-, 58.9 WAR, 58.3 JAWS
David Findlay, LF
Findlay is the best Scottish player in history. Mohammed Cocker previously held that distinction, but Findlay is the first Scotsman to make the Hall. Findlay's total career value is somewhere north of Justus Whitham and Blake Gribler. He had five 20 HR-20 SB seasons and came close to a 30-30 season in 1961 with 30 HR and 26 SB. Fielding was never his focus, but he was slightly above average at the beginning of his career, becoming more of a liability as he aged.
Initial Acquisition: Drafted 5th overall in 1946 by the Royals out of Pendleton
MLB Awards: 1 ROY, 1 Youssef Raadouni GG, 4 AS, 4 SS
Career Stats: 11740 PA, 2948 H, 413 HR, 313 SB, .349 wOBA, 119 wRC+, -41.7 ZR, 54.2 WAR, 43.2 JAWS
Hamilton Mendoza, LHP
Mendoza's career ended just before the steps of the Hall, most likely due to his late start. Despite signing with the Orioles on his 16th birthday, he didn't pitch a full season in the majors until he was 25. His 27-30 year-old seasons were dominant and he put up 6-7 WAR each year.
Initial Acquisition: Signed in 1945 with the Orioles out of the Dominican Republic

Career Stats: 2640.7 IP, 617 BB, 1882 K, 3.47 FIP, 87 FIP-, 53.4 WAR, 49.2 JAWS
