Smyly (elbow) will throw a bullpen session Saturday, Bob Dutton of the Tacoma News Tribune reports.
This news comes after Smyly took another step forward Thursday by throwing off a mound. Saturday will be another significant step for Smyly as he'll log a full bullpen session. Given the length of Smyly's absence, he'll likely need a couple additional bullpen sessions before the Mariners map out a rehab assignment for the left-hander.
