Pitchers like New York Yankees star Gerrit Cole and reigning NL Cy Young award winner Trevor Bauer have been at the forefront of MLB’s war against foreign substances in 2021. In June, those two have combined for 23.1 innings pitched, while allowing 14 earned runs, 25 hits, 8 walks, and 31 strikeouts. On June 3, Gerrit Cole surrendered five earned runs in a loss to the Rays. It was just the fifth time since 2018 that Cole had allowed five or more earned runs in a start. Meanwhile Bauer has allowed at least three earned runs in each of his last three starts. Since the start of 2020, Bauer only has three other such starts.
