Brian Duensing has an intercostal strain, so the Twins have placed him on the disabled list and called up Caleb Thielbar from Triple-A to take his spot as a left-handed reliever.
Thielbar spent most of the past two seasons in Minnesota’s bullpen and pitched well with a 2.59 ERA and 74/30 K/BB ratio in 94 innings, but the Twins still demoted him to Triple-A at the end of spring training and went with Duensing and Aaron Thompson as their lefty setup men.
Duensing had an ugly outing Thursday in which he turned a blowout into a save situation for closer Glen Perkins and he heads to the DL with a 7.36 ERA in six appearances.
The Athletic’s James Fegan reports that the White Sox are shutting down starter Lucas Giolito for the remainder of a season. An MRI revealed a mild lat strain, which typically comes with a three- to four-week recovery timetable. The third-place, 65-84 White Sox have nothing left to play for, so it makes sense to play it safe with their prized young hurler.
Giolito, 25, had a breakout season. He went 14-9 with a 3.41 ERA and a 228/57 K/BB ratio in 176 2/3 innings. He made his first All-Star team and will likely earn a few downballot votes for the AL Cy Young Award.
Giolito was scheduled to start Tuesday’s series opener against the Twins. Ross Detwiler will start in his place opposite Martín Pérez.
