Tejada, 23, has had a pretty awful year to this point. He's hitting .209/.267/.262 with two stolen bases and 18 runs scored in 204 plate appearances. He was actually in danger of being demoted to Triple-A, though he was reportedly spared after the Mets' rally against Mariano Rivera and the Yankees Tuesday.
In a corresponding move, Omar Quintanilla is headed to the Mets -- likely to be the everyday shortstop. The 31-year-old infielder has a career .220/.279/.302 line with only three career stolen bases in 292 games. He's hitting .333/.419/.484 with nine doubles, two triples, two homers and 18 RBI for Triple-A Las Vegas, but that's a notorious hitter's haven within the hitter-friendly Pacific Coast League.
As the Mets needed room on the 40-man roster for Quintanilla, they have moved reliever Frank Francisco to the 60-day disabled list.
