Mariners vs. Red Sox: Rojas ramps up, Kirby's streak ends, new guys show out

Best Pitcher: George Kirby

5.1 IP, 7 H, 2 ER, 1 BB, 2 K

Kirby's quality start streak of nine had to come to an end eventually and the Red Sox were the team to do it. Despite keeping it to just two earned runs, his pitch count was at 95 and he still needed two more outs to extend the streak. He had just six whiffs but amassed 17 called strikes, seven of which were from his slider. Of his seven hits, three came against his four-seam fastball, and two came against his splitter.

Honorable Mention: Luis Castillo

6.0 IP, 6 H, 3 ER, 1 BB, 4 K

Although he managed to net the only win of the series, Castillo's start left a little to be desired. He had nine whiffs, three of which were foul tips, and 13 called strikes, six of which came against his four-seam fastball. Nonetheless, it was a quality start and put his July ERA at 1.99 over his five starts, a major improvement over the 5.13 he had in June.
