Kowar (0-6) allowed five runs on five hits and a walk while striking out six in four innings to take the loss against the Twins on Sunday.
Kowar gave up four runs in the top of the first inning before recording an out, but he settled down later in his outing and retired nine consecutive batters across the next three innings. However, he was forced to finish the season with his fourth loss in his last five appearances. The right-hander made nine appearances (eight starts) during his first major-league season and recorded an 11.27 ERA and 2.08 WHIP in 30.1 innings.
