Loewen was the #4 pick of the 2002 draft for the Baltimore Orioles and became their top pitching prospect. He would come up as a pitcher over three season ( 2006-2008) with the Orioles in which he appeared in 35 games, 29 starts with an ERA of 5.38 and a WHIP of 1.64. In 2008 he announced he would no longer pitch due to chronic arm injuries but was going to attempt to transition to a corner outfielder/ 1B.
He signed a minor league deal with the Jays as a positional player in 2009 and returned to the majors as Sept. call-up in 2011. After the seasons he was out-righted and became a free agent.
Here's a few articles from Toronto on how his transition was going...
“No doubt in my mind Adam’s a major-league talent,” general manager Alex Anthopoulos told reporters in a conference call Thursday. “He can play all three positions. We saw him in centre.” source Toronto Sun
Loewen didn’t show much of a bat during his brief stint in the majors, hitting just .188 with 1 home run, but he did show good athleticism and raw power. Loewen’s was a great story to follow all season, as he wound up tearing it up AAA Las Vegas, putting together a solid .306/.377 season that included 17 homers. Having made his conversion from pitching just 3 years ago, Loewen may still be a little rough at the plate, but he does play multiple positions, and the the raw ability is there for him to perform as a 4th/5th OF on a major league club. Hopefully, he’ll find a chance to do so. If not, I’m sure Jays fans will be happy to have the Canadian back. source Rant Sports MLB Blue Jays
Baltimore Sun found scouts who saw him play as a high school kid in Canada and this is what one of them said.
“He was the best high school player in the world,” said Hamilton. “I truly believe he would have been a first rounder as a hitter and position player if he decided not to pitch in high school.He played the game with an incredible ease.” source Baltimore Sun
