Tejada, who signed to a minor-league deal in early May and has been playing for Triple-A Norfolk, asked for and was granted his release by the organization, according to a club source.
The 38-year-old former AL MVP was hitting .259 with zero homers and 18 RBI in 36 games at Norfolk. He was 1-for-4 with a double in his final game with the Tides on Monday afternoon.
The Orioles signed Tejada because he provided a solid glove at third base and a right-handed bat, but Tejada hit for no power at all and had just five extra-base hits in 135 at bats.
It's the second time in three days that the Orioles have granted a veteran minor leaguer his release. On Saturday, the organization granted 49-year-old left-hander Jamie Moyer his release after the completed a three-start stint at Norfolk.
Before the 2004 season, the Orioles signed Tejada to a six-year, $72-million deal. He played four years in Baltimore, averaging 25 homers and 107 RBIs and making the AL All-Star team three times before being dealt to Houston before the 2008 season.
Tejada returned to the Orioles briefly in 2010, hitting .269/.308/.362 in 98 games before being traded to San Diego.
Tejada, who won the 2002 AL MVP with Oakland, put up a .305/.354/.481 line in parts of five seasons with the Orioles.
It's uncertain whether Tejada will try to latch on with another organization or retire.
