[2] During this time, Clark played in parts of four seasons with the Rochester Red Wings, the Orioles' Triple-A affiliate, from 1998 to 2002 and was named the team captain.

[3] After his contract was purchased by the Orioles on July 16, 2002,[4] he finally made his major-league debut as a designated hitter batting leadoff that same day in a 6–1 victory over the Seattle Mariners at Camden Yards.

[5] He spent the 2005 season with the Rookie-level Gulf Coast League Pirates and the Double-A Altoona Curve, batting a combined .394 with two home runs and 17 RBI in 39 games.

Clark played most of the year with their Triple-A affiliate, the Ottawa Lynx, but was called up to Baltimore for a brief stretch during the months of June and July.

[5] On May 30, 2007, while playing third base for the Blue Jays, Clark let an easy pop fly fall after Alex Rodriguez yelled "Mine" in order to distract the infielders.

Clark was cited in the 2007 Mitchell Report on performance-enhancing drugs in baseball,[8] but was later acquitted when it was discovered his GH was bunk because he bought it from a false Mexican source.

[citation needed] He became a free agent at the end of the season and signed a minor league contract with the Toronto Blue Jays on January 16, 2009.
