Quick Hits: Harper, Knapp, Wilson, Brewers

The Nationals are promoting Bryce Harper to Double-A in time for tonight’s game. The 18-year-old, who was the first overall selection in last year's draft, had a .318/.423/.554 line with 14 homers and 19 steals at Class A. Here are some fourth of July links in anticipation of Harper’s Double-A debut…

• Trade talk is picking up, but some teams believe there’s a lack of difference makers available on the trade market, according to ESPN.com’s Buster Olney. The few trade candidates who could make a difference in the pennant race are going to be difficult to obtain, Olney writes.
• Former Tigers pitching coach Rick Knapp tells John Lowe of the Detroit Free Press that three general managers called him to discuss possible jobs. The Tigers fired Knapp yesterday.
• Jamey Newberg hopes C.J. Wilson feels like a winner in Texas so that he re-signs with the Rangers this offseason, when he becomes a free agent.
• Casey McGehee already has two hits today, but he has just a .226/.276/.313 line this season. Brewers GM Doug Melvin told Tom Haudricourt of the Milwaukee Journal Sentinel that he doesn't plan to demote the third baseman to the minors (Twitter link).
