Michael Kopech made his Major League Baseball debut for the Chicago White Sox Tuesday. You know him from the Charlotte Knights. His ERA in Charlotte was 3.70, but he’s been sensational since the Triple-A All-Star Game break. He’s 22, and one of baseball’s top pitching prospects.
The first Minnesota Twins’ hitter he faced Tuesday was Joe Mauer, who singled. The second hitter was Eddie Rosario, who is hitting .293 with 22 home runs. He singled. But Kopech got a strikeout, induced a double play and retired the side. In the first two innings he struck out four batters.
