TROY PERCIVAL TO RETIRE AS AN ANGEL
Angels' all-time saves leader will sign a minor league contract with club and retire

ANAHEIM, CA - The Angels Thursday announced that Troy Percival, the club's
all-time saves leader, will sign a minor league contract next Monday and
then officially retire. To commemorate the event, Percival will be on hand
Opening Night at Angel Stadium on April 2 to throw out the honorary first pitch.

"I'm very proud to be a part of this organization," said Percival. "This
club has always embraced me and my family. I'm honored to retire as an
Angel."

"Troy Percival has been an integral part of the success and tradition of
Angels Baseball for many years," said Angels Vice President & General
Manager Bill Stoneman. "It is very appropriate that he retire as an
Angel."

Percival, who currently serves as an Angels' special assignment pitching
instructor, pitched 11 seasons in the Majors with the Angels (1995-2004)
and Tigers (2005-2006), compiling a 30-41 record with 324 saves and 3.10
ERA (611.2 IP - 211 ER) in 605 games. His 324 saves entering 2007 is tied
for 11th (Billy Wagner) on the all-time Major League list. He stands as
the Angels' lifetime leader in saves (316) and games pitched (579).

He spent the entire 2006 season on the disabled list with the Tigers after
suffering a serious injury to his right forearm in July 2005 while pitching
for Detroit. Percival worked for the Tigers as an advance scout in 2006.

A key member of Angels' 2002 World Series team, he was on the mound for
each of the Angels' three series-clinching victories of the 2002
Post-Season and his seven saves (seven chances) during the 2002 playoffs
tied a Major League Post-Season record. He logged a career-high 42 saves
in 1998 and enjoyed his best season in 2002 with a 4-1 record, 40 saves, 68
strikeouts and 1.92 ERA.

The four-time All-Star resides in Riverside, CA, with his wife Michelle and
children
Cole and Avery.
