Since games in Minor League doubleheaders are limited to seven innings, Owens got credit for his second shutout this season. His first was an Opening Day no-hitter that was shortened to six innings because of rain.
Owens has thrown at least seven scoreless innings in four of his past five starts. The lone exception was last Saturday, when he allowed one run in 6 2/3 innings at Akron. During that stretch, which dates back to May 24, he is 5-0 with a 0.25 ERA and 32 strikeouts in 35 2/3 innings.
Owen's dominance isn't limited to the last month. With Friday's victory, he improved to 9-3 with a 1.99 ERA this season. He has struck out 89 batters and walked 35 in 86 innings. He leads the Eastern League in wins, ERA, strikeouts, WHIP (1.03) and complete games (three).
The first game of the doubleheader was the completion of Thursday's game, which was suspended in the third inning. Portland also won that game, 4-2. Catcher Blake Swihart, the Red Sox's No. 3 prospect and No. 51 overall, scored twice and drew three walks in the doubleheader.
