Headline: Harrison did not factor into the decision Friday against the Tigers, allowing three runs on seven hits and three walks over three innings. He struck out six.
Story: The Red Sox southpaw struggled out the gate, as he escaped a scoreless first inning in which he conceded two walks and a hit. The Detroit lineup finally broke through against Harrison in the fourth, when the first five batters reached, plating three runs. Given that the 24-year-old tossed 65 pitches in this appearance, he likely wraps his regular season with a 4.04 ERA, 1.37 WHIP and 38:14 K:BB across 35.2 total frames with Boston and San Francisco.
Description: Harrison did not factor into the decision Friday against the Tigers, allowing three runs on seven hits and three walks over three innings. He struck out six.
