Thielbar threw two perfect innings while striking out two in Friday's 6-3 win over the Guardians.
Thielbar struggled to start the season with a 8.04 ERA and 5.2 BB/9 in his first 15.2 innings. However, he's turned his season around since June 12 with a 2.81 ERA and 19:5 K:BB over his last 16 innings. He had seemingly lost the ability to control his looping curveball early in the season, but has gotten back to peak form. He could play a key role in high-leverage spots for the Twins as the top southpaw in the bullpen, and he's picked up two of his eight holds on the year in his last three appearances.
