Had there been a Rookie of the Year Award in 1912, there is a good chance that Del Pratt of the St. Louis Browns would have won it.  That year he batted .302 with 172 Hits, and he was close to that in 1913 with 175 Hits and a .296 Average.

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.
