Tatis hit .298 with 34 home runs, 107 RBIs and 104 runs scored in 1999 as the Cardinals third baseman.
"It's always great to come back here and play," Tatis said. "I have a lot of great memories here. St Louis is one of the best places that I have ever played baseball, and I just love to come back here. I appreciate what the fans did and do for me. It's unbelievable. It's amazing to play here in St. Louis."
Tatis spent three seasons in St. Louis before moving on to stops in Montreal and Baltimore before latching on with the Mets a year ago.
"I was very happy when I played here," Tatis said. "I enjoyed my time over here. Like I said, I have a lot of great memories here. Making the playoffs and seeing how the fans reacted, it was just amazing to me. It was a joy to play here."
Tatis entered Tuesday's game hitless in seven at-bats this season as a backup infielder and outfielder for the Mets.
