Tejada will start at third base for Wednesday's game against the A's after his contract was purchased by the Giants prior to the game, Andrew Baggarly of the San Jose Mercury News reports.
Tejada is in the lineup at third base while batting ninth Wednesday, which will be his first game back in the majors since May 26 when he was a member of the Cardinals. He was just 6-for-34 during his time with St. Louis, batting a quadriceps injury, but will bring solid defense to the Giants' infield while he is with the club.
