Buck Showalter is the ninth man chosen to manage the Orioles since Peter Angelos took over as principal owner in August 1993. Here's a look at the tenures of the eight men who preceded Showalter.Year(s) Manager Record Highlight Where it went wrong2010 Juan Samuel 16-31The Orioles' four-game sweep of the first-place Rangers in Texas on July 8-11, which sent the team into the All-Star break with momentum Put in a difficult position, Samuel was unable to coax much improvement from the team.2007-2010 Dave Trembley 187-283 After taking over for Sam Perlozzo in June 2007, managed the Orioles to a 19-13 mark to start his tenure. It led to the eventual removal of the "interim" title. To start 2010, the Orioles slid to a 15-39 mark before firing him. Dating to the 2009 All-Star break, he had managed the Orioles to a 35-89 (.282) record.2005-2007 Sam Perlozzo 122-164 Being named interim manager Aug. 4, 2005, and seeing the interim label removed at the end of the season. He described it as a "dream job." On May 13, 2007, Jeremy Guthrie held the Red Sox to three hits over the first eight innings en route to a 5-0 lead, then was pulled with one out in the ninth. The bullpen faltered and the Orioles lost, 6-5.2004-2005 Lee Mazzilli 129-140 Starting the 2005 season by spending 62 days atop the American League East, by far the longest period in the decade the Orioles were in first place. The team's 4-16 start after the All-Star break, during which first baseman Rafael Palmeiro was suspended for 10 days after he tested positive for stanozolol. 2000-2003 Mike Hargrove 275-372 A six-game winning streak in his first month on the job. The Orioles took two games each from the Twins, Devil Rays and Athletics to improve to 11-5. In mid-August 2003, the Orioles took three of four from the Red Sox to improve to 57-59. When they got swept by the Rays in the next series, Hargrove was criticized for taking the sweep too calmly.1998-1999 Ray Miller 157-167 Ending the 1999 season on a positive note, winning 20 of 28 games in September. Angelos and then-GM Frank Wren clashed at the end of the '99 season over Miller's future. By the new millennium, Wren and Miller were both fired. Part of the clash centered on the decision by Wren and Miller on Sept. 17 to depart for a West Coast trip without Cal Ripken Jr., forcing the star to make other travel plans.1996-1997 Davey Johnson 186-138 Back-to-back ALCS appearances, losing 4-1 to the Yankees in '96 and 4-2 to the Indians in '97. Named AL Manager of the Year in '97. After consecutive playoff berths, the Johnson-Angelos relationship ended in a nasty divorce, with neither able to get along for the sake of a talented team. Most noteworthy was Johnson's fine of Roberto Alomar, which he determined should be paid to a charity that Johnson's wife was on the board of.1995 Phil Regan 71-73 Seemingly saving his job by winning 12 of the final 15 games, including five consecutive shutouts to end the season. Sep. 6, 1995 was Cal Ripken's 2,131st consecutive game played, breaking Lou Gehrig's record. On July 30, the Orioles climbed one game above .500 at 43-42, 41/2 games out of first place, but then dropped 12 of their next 15 contests, falling to 15 games out of first.
