Admittedly, this rotation was largely assembled based on technicalities, as three of these four pitchers (with Ponson being the only exception) played either high school or college baseball in the U.S. Cox is the only guy here who pitched in more than 14 games with the Cardinals, but interestingly every one of them has pitched for the Cardinals within the past 30 years–with Jackson and Masterson having pitched in St. Louis this decade.
Danny Cox- England
The Northampton, UK-born righthander was a steady performer in the Cardinals’ rotation from 1983-88.
Edwin Jackson- Germany
Though he was with the Cardinals for just over three months, the Neu-Ulm, Germany-born Jackson played a major role while in St. Louis, appearing in 13 games (starting 12) down the stretch and then starting four postseason games as the Cardinals won the World Series.
Sidney Ponson- Aruba
Ponson, a native of Noord, Aruba, made 13 starts and one appearance out of the bullpen for the Cardinals during the early part of the 2006 season. He had a 5.24 ERA and a 1.62 WHIP, but he ultimately earned a World Series ring as the Cardinals went on to win after releasing him in July.
Justin Masterson- Jamaica
Masterson, who was born in Kingston, Jamaica while his dad was serving as the dean at a seminary, was acquired by the Cardinals at the trade deadline in 2014. While the player the Cardinals gave up for him–former first-rounder James Ramsey–hasn’t turned out, the Masterson trade ranks as one of John Mozeliak’s worst. The former All-Star posted a 7.90 ERA over six starts before being removed from he rotation and left off the postseason roster.
