PHOENIX -- Dodgers shortstop Corey Seager was sidelined again on Saturday, this time with upper back tenderness.
Seager, who returned to Cactus League action on Friday after missing three days with a right shin bruise, was told to "lay low" on Saturday and not swing a bat, manager Dave Roberts said.
Roberts said the injury didn't occur on a swing but "on a throw or awkward movement." Seager was involved in a tricky double play on Friday, taking a flip from second baseman John Forsythe and making powerful, yet off-balance throw to first base.

"Right now, with so many days left in [Spring Training], what we [will] do is err on the side of caution and he won't swing the bat today," Roberts said.
Before Friday, Seager hadn't played since Monday -- when he fouled a pitch off his right shin. Seager missed nearly two weeks last spring with a twisted knee, but that didn't stop him from going on to unanimously win the National League Rookie of the Year award and finish third in NL Most Valuable Player voting.
