East Notes: Phillies, Harper, Marrero, Cano

In the aftermath of a 20-inning loss to the Marlins, the Mets designated Rick Ankiel for assignment and recalled Kirk Nieuwenhuis. However, the team's biggest concern was the health of young ace Matt Harvey, who left the game with stiffness in his lower back. But as Kristie Ackert of the New York Daily News reports, Harvey is apparently fine and will make his next scheduled start on Friday. Here's more news from around MLB's East divisions:

• The Phillies' recent hot streak may have turned the club from sellers to buyers, argues Bob Brookover of the Philadelphia Inquirer. Brookover notes the discussion just last week was about which top players would be unloaded, whereas now it is about what pieces could be added to the young core. 
• Nationals GM Mike Rizzo downplayed Bryce Harper's visit to orthopedic surgeon Dr. James Andrews for a second opinion regarding the bursitis in the outfielder's left knee, according to MLB.com's William Ladson. "There's no worry," Rizzo said. "It is our protocol that players get a second opinion on any part of the body that we feel is a disabled list-type of injury. Guys get second opinions all the time here, and every guy that we put on the disabled list has gotten a second opinion." Harper is eligible to be activated from the 15-day disabled list on Tuesday and is expected to rejoin the team then.
• Chris Marrero may be up to stay, although the first baseman is temporarily serving as the Nationals' 26th man for today's doubleheader reports Adam Kilgore of the Washington Post. The former first rounder may help the Nationals' disappointing offense get going, as Marrero has hit for a .306/.355/.502 line in 228 plate appearances.
• Joel Sherman of the New York Post writes that the Alex Rodriguez saga hurts Robinson Cano in his negotiations with the Yankees in a way you might not expect.  While Rodriguez’s record deal looks like it has soured from a value perspective, Sherman argues that the negative attention the contract has gotten has been even more detrimental. Cano is the top ranked free agent on MLBTR'S 2014 Free Agent Power Rankings.
