Brubaker (shoulder) won't return prior to the end of the regular season, Alex Stumpf of DKPittsburghSports.com reports.
Brubaker will increase his throwing distance by playing catch off flat ground from 120 feet in the coming days, and he'll use all of his pitches during the throwing session. Although the right-hander is making progress and should have a relatively normal offseason, he won't have enough time to return by the end of the regular season. Brubaker made a career-high 24 major-league starts this year and posted a 5.36 ERA and 1.29 WHIP in 124.1 innings.
