O’Sullivan on target again as 51s top Tacoma

Sean O'Sullivan pitched six shutout innings, and Moises Sierra and David Cooper homered to power the 51s to a 4-0 victory over the Tacoma Rainiers in a Pacific Coast League game Friday night in Tacoma, Wash.

O'Sullivan (7-4), who joined Las Vegas last week after the Toronto Blue Jays purchased his contract from the Kansas City Royals, improved to 2-0 with the 51s (46-35) after his second straight dominating performance. In 12 innings, he's given up no runs on five hits and struck out nine.

On Friday, the right-hander limited the Rainiers (32-48) to two hits and three walks and struck out five.

Sierra followed Eric Thames' two-out single in the second inning with his 13th home run of the season to open the scoring. Las Vegas went up 3-0 in the third when Jonathan Diaz walked and scored from second when second baseman Nick Franklin misplayed Cooper's grounder.

Cooper hit his seventh home run of the season in the sixth to cap the scoring.

Tacoma starter Brian Sweeney (3-2) gave up four runs, three earned, on six hits and two walks in seven innings.
