After a rough road trip seemingly knocked the Milwaukee Brewers out of contention, General Manager Doug Melvin acknowledges that the team is fielding trade inquiries for ace pitcher Zack Greinke.

“I think people know that,” Melvin said Thursday.

Melvin confirmed Greinke’s availability in comments to USA Today and Milwaukee’s WTMJ radio earlier Thursday.

Melvin did not go into detail on how many teams have expressed interest in the 2009 AL Cy Young Award winner, saying only that the trade market always heats up with the July 31 non-waiver trade deadline approaching.

Twins place Swarzak on DL

The Minnesota Twins placed right-handed reliever Anthony Swarzak on the 15-day disabled list with a right rotator cuff strain.

To take Swarzak’s place, right-hander Luis Perdomo’s contract will be selected from Triple-A Rochester. To make room for Perdomo on the 40-man roster, right-hander Carl Pavano will be transferred to the 60-day disabled list.

Pavano already has missed 52 days because of a right shoulder injury, so this won’t extend his absence by much. He recently began throwing off a mound.

Perdomo started with Double-A New Britain and was promoted to Rochester. He has a 2.14 ERA in 59 innings with 61 strikeouts this season between the two teams. Perdomo would be the 41st player to appear in a game this year for the Twins.

Captor releases Ripken’s mom

The curious circumstances surrounding the kidnapping and then release of Cal Ripken Jr.’s 74-year-old mother are all the talk of her community outside Baltimore, where such crime doesn’t happen and where her neighbors know the matriarch of the famous baseball family as “just Vi.”

Vi Ripken was found bound but unharmed in her car Wednesday morning, a day after being abducted at gunpoint at her house, blindfolded and driven around by her kidnapper, police said. He left her in her silver Lincoln Continental near her house in Aberdeen. She was tied up, but unharmed.

She described him as a tall, thin white man with glasses wearing camouflage clothing, but police had few other details and didn’t give a motive Thursday, though they did release photos of the suspect.

Ripken told a neighbor that her kidnapper didn’t seem to know her son is the hall of fame infielder with the nickname “Iron Man” for playing in 2,632 consecutive games during his 21-year career with the Baltimore Orioles.

Investigators said the kidnapping was peculiar, especially since there was no ransom demand.

Bonds seeks delay for reply

Barry Bonds requested another delay in his appeal of his obstruction of justice conviction. Bonds’ lawyers asked the 9th U.S. Circuit Court of Appeals in San Francisco to postpone the deadline for his reply brief from Aug. 2 to Aug. 16. A jury found Bonds guilty in April 2011 of one count of obstruction of justice, finding he gave an evasive answer in 2003 to a grand jury investigating illegal steroids distribution.
