Bits: Trevor Cahill's struggles continue

&#8226 Oakland Athletics right-hander Trevor Cahill walked seven Kansas City Royals on Tuesday, allowing four hits and four runs in 4 1/3 innings. Not too long ago, Cahill was 6-0, and when June began, his ERA was 2.31. Now he's 6-5 with a 3.42 ERA, having walked 21 hitters in five starts. He should be benched in all fantasy formats.

&#8226 Colorado Rockies outfielder Charlie Blackmon had two hits, scored a run, knocked in a run and stole his fourth base Tuesday, and he's starting to get attention in deeper leagues. He should. Blackmon has stolen a base in four consecutive games, and there is some power and batting average upside.

&#8226 Pittsburgh Pirates right-hander Jeff Karstens lowered his ERA to 2.66 with 6 2/3 shutout innings of three-hit ball in Houston on Tuesday, earning his fourth win. Karstens continues to thrive anonymously; he's owned in 9.6 percent of ESPN standard leagues, despite a 1.08 WHIP in 71 innings. He won't win much or pile on the strikeouts, but there's value here.

&#8226 Philadelphia Phillies outfielder Domonic Brown smacked a pair of long home runs against Florida on Tuesday, and his batting average against right-handed pitching is .276, with a .900 OPS. Brown is a top-50 outfielder already, with power and speed, and should be owned in more than 27.1 percent of leagues.

&#8226 Toronto Blue Jays second baseman Aaron Hill homered Tuesday, only his second in 194 at-bats, but since he hit 36 home runs in 2009 (and 26 last year) he is owned in 72.1 percent of leagues. Despite the home run, Hill really isn't showing signs of consistent power or batting average. He's not a top-10 second baseman.

&#8226 Texas Rangers right-hander Alexi Ogando was treated rudely by New York Yankees hitters Tuesday, allowing six hits and six runs in a messy second inning. Ogando suffered his first loss, and his ERA rose from 2.10 to 2.71. However, Ogando has been excellent this season. Leave him active Sunday in Atlanta.
