Prielipp (3-7) took the loss Friday in San Diego, giving up six runs on eight hits with seven strikeouts and two walks over six innings.
After a six-start string of solid performances -- during which he posted a 4.09 ERA, 1.27 WHIP and 10.1 K/9 -- Prielipp has now surrendered 14 earned runs across his past two outings. The left-hander had a strong start to his MLB career with a 2.88 ERA and 0.96 WHIP in his first five big-league appearances earlier this year, but he's been unable to maintain that level of effectiveness and has a 5.57 ERA and 1.40 WHIP through 18 starts overall.
