The Indians shuffled their roster Thursday before opening a four-game series against the Mariners at Safeco Field.

First baseman Carlos Santana was placed on the paternity list and right-hander Scott Atchison was placed on the 15-day disabled list with a sprained left ankle. First baseman/outfielder Jerry Sands and right-hander Austin Adams have been promoted from Class AAA Columbus to replace them.

Santana is hitting .221 (33-for-149) with six homers, 27 RBI and an AL-leading 37 walks. Sands, making his second tour with the Tribe this season, is hitting .270 (20-for-74) with four homers, 14 RBI and a .896 OPS at Columbus.

Sands, in his first tour with the Indians, hit .348 (8-for-23) with four RBI in nine games.
