The Mariners began the second half of the 2016 season Friday night with ace Felix Hernandez and right-hander Taijuan Walker on the 15-day disabled list, but Hernandez is expected to return Wednesday against the White Sox and Walker later this month in what looms as a critical stretch before the Aug. 1 non-waiver trade deadline.
Manager Scott Servais announced Friday that left-hander Mike Montgomery (3-3, 2.06 ERA) will start Sunday's series finale, then fellow southpaws Wade LeBlanc (1-0, 3.52 ERA) and Wade Miley (6-6, 5.44 ERA) will start Monday and Tuesday, respectively, against Chicago.
Montgomery got his first spot start of the year this past Sunday in Kansas City, allowing one run over 6 1/3 innings.
