White was recalled from Triple-A Oklahoma City on Saturday.
White was sent down in mid-September, but he'll rejoin the major-league roster after Clayton Kershaw (forearm) was placed on the 10-day injured list Saturday. The right-hander has recorded a 3.74 ERA and 1.20 WHIP in 45.2 innings across 20 appearances (four starts) in the majors this year and will likely serve as a reliever following his call-up.
