Baker has averaged 15 points and 7.4 rebounds in 791 NBA games with the Clippers, Rockets, Knicks, Celtics, SuperSonics and Bucks. He said in camp last month he felt great, having trimmed down to 250 pounds after once weighing close to 300 pounds.
The move reduced the Timberwolves' roster to 14 players, with one spot open.
