Fernando Tatis, Jr. took about 50 swings during batting practice on Monday, an important step toward his return from a partially dislocated left shoulder.

Tatis also shagged fly balls in center and eventually moved to right field for one-on-one work with San Diego Padres outfield coach Wayne Kirby.

The Padres maintain that no decision has been made on where Tatis will play when he's activated from the injured list.
