In a move we all knew was coming at some point today, the Cincinnati Reds activated Luis Castillo. He was the listed starter for tonight’s series opener against the Milwaukee Brewers and everyone was just waiting for the other side of the transaction. That move turned out to be that left-handed reliever Phillip Diehl was designated for assignment. Cincinnati also announced that reliever Buck Farmer had cleared waivers and was outrighted to Triple-A Louisville.
After dominating in Triple-A Louisville since the start of the 2021 season, Phillip Diehl finally got called up to join the Reds two weeks ago. He debuted for Cincinnati against the San Diego Padres on April 27th and threw 2.0 perfect innings with two strikeouts. The hometown kid made the hometown proud on that night. But things went south in a hurry after that. In Colorado he allowed seven baserunners in just 0.2 innings and gave up four runs on the 29th. The lefty gave up a solo homer in Milwaukee on May 3rd before firing a perfect inning on the 5th. On Saturday against Pittsburgh he gave up two home runs in 0.2 innings, leaving him with an ERA of 11.12 through his five appearances with the Reds. With Diehl no longer on the roster, Cincinnati does not have a single left-handed pitcher that’s currently active.
Luis Castillo made three appearances in the minor leagues while on rehab. In the first two games he saw his control fade in his final inning and racked up more than a few walks. But in his final rehab start last week in Triple-A with the Louisville Bats, he tossed 4.1 shutout innings with just two walks and added seven strikeouts against Indianapolis. Between his three games he was charged with just one earned run over 10.1 innings – one start with High-A Dayton and then two with Louisville.
