ST. LOUIS • Dan Kantrovitz, the St. Louis native who oversaw the Cardinals' drafts that landed pitchers Michael Wacha and Marco Gonzales as the team's director of amateur scouting, has left the team to accept a role in the Oakland Athletics' front office.

The A's announced today that Kantrovitz will be the team's assistant general manager, serving alongside general manager Billy Beane.

"Dan did a great job for us," Cardinals general manager John Mozeliak said. "This is a wonderful opportunity for him. We wish him the best. During his three years we got to work together in this department, we enjoyed what he brought to the draft and to the organization. From that standpoint, we have high expectations from the draft."

Mozeliak said he intends to move swiftly for a replacement.

He will consider internal and external candidates for the job of director of amateur scouting. He intends to have a replacement before the start of the winter meetings in San Diego on Dec. 8.

Kantrovitz is a graduate of John Burroughs High. He attended both Brown and Harvard, and his baseball career gained speed when he worked for the Oakland Athletics. He served as the A's director of international scouting from 2009-2011. He joined the Cardinals, and in his first season as the head of the team's draft the Cardinals selected Wacha 19th overall. Within 16 months of that draft, Wacha was a starter for the Cardinals and the MVP of the National League championship series. In 2013, the team picked lefty Gonzales in the first round and he made his debut within a year of signing as well.

This was his second stint with the Cardinals.

With Oakland, he replaces Farhan Zaidi, who moved to the Dodgers.

He is the second Cardinals employee to leave for Oakland this offseason, following Mike Aldrete, who left his position as bench coach on Mike Matheny's coaching staff to take the same role with the A's.
