Carroll was traded to the Rangers for cash considerations Wednesday, Daryl Van Schouwen of the Chicago Sun-Times reports.
Carroll had been outrighted to Triple-A Charlotte on Thursday and will now pack up and join the Rangers. Carroll, a former third-round pick, hasn't been able to find his game in Triple-A this season, going 2-8 with a 5.55 ERA through 60 innings of work in a combined role both as a reliever and starter. The 31-year-old also gave up three earned runs in three appearances out of the White Sox's bullpen this season. He will likely play out the season as minor league depth.
