Chapman's start pushed back due to blister

CLEVELAND -- A blister appears to have pushed back Reds prospect Aroldis Chapman's next start for Triple-A Louisville.

Chapman was slated to start on Monday vs. Scranton/Wilkes Barre, but that turn will be taken instead by right-hander Ben Jukich.

Against Lehigh Valley on Wednesday, the 22-year-old Chapman pitched 5 2/3 scoreless innings with three hits and three walks allowed. He struck out seven and earned a 4-2 victory but had to leave with two outs in the sixth when a blister developed on his left middle finger.

In eight starts for Louisville, Chapman is 4-2 with a 3.98 ERA. The Cuban pitcher, who was signed to a six-year, $30.25 million contract in January, has 48 strikeouts and 24 walks in 40 2/3 innings.

It was not known when Chapman would make his next start.
