The Dodgers placed Sasaki on the 15-day injured list Thursday due to a blister on his right middle finger.
Sasaki had a nice seven-game stretch with a 2.63 ERA and 1.12 WHIP prior to taking a no-decision in Wednesday's 6-5 loss to Atlanta. He surrendered four runs to Atlanta as he developed the blister, which has now sent him to the injured list. In a corresponding move Thursday, the Dodgers recalled Seth Halvorsen from Triple-A Oklahoma City while Eric Lauer will take over Sasaki's rotation spot.
