Harry Howell was traded from the New York Highlanders to the St. Louis Browns for the 1904 Season, and while he lost more games than he won, the Browns were not that good. Howell was a starter for five seasons, and he had three years where he had an ERA under 2.00, and in all of those years, his WHIP was under 1.100. In four of those years, he was in the top ten in ERA, despite his losing record.
An American League MVP with the Oakland A’s in 2002, Miguel Tejada signed with Baltimore as a Free Agent in 2004, where he would spend four years.
Milt Pappas debuted as a teenager for the Baltimore Orioles in 1957, and a couple of years later, he was the ace of their staff. An All-Star in both 1962 and 1965, Pappas never had a losing record in Baltimore, and with the team, he was in the top ten in ERA six times and in WHIP four times.
Nels Potter was considered to have good stuff, but the screwball specialist just couldn’t put it together, and playing for an awful team like the Philadelphia Athletics in the 1930s didn’t help. By 1942, he was back in the minors, but the St. Louis Browns would select him from the Red Sox Organization in the Rule 5 Draft.
