NL East Notes: Phillies, Gonzalez, Braves, Nationals

Marlins hitting coach Tino Martinez resigned today amid allegations of verbal and physical abuse of players, according to Clark Spencer of the Miami Herald. Two sources told Spencer the agent for recently-demoted second baseman Derek Dietrich contacted the team several months ago to report an incident where Martinez erupted in anger unjustly and grabbed a player by his neck and neck chain. The MLBPA was notified of the alleged incident, as well as others involving Martinez, and the union then contacted the Commisioner's office and that office was expected to contact the Marlins on Tuesday, Spencer reports. Martinez, who had never been a Major League coach before this season, was owner Jeffrey Loria’s hand-picked selection to become Marlins' hitting coach. The Red Sox also had interest in hiring Martinez before he took the job with the Marlins. In other news and notes coming from the NL East:

• The Phillies are still not acknowledging the signing of Miguel Alfredo Gonzalez as sources say the Cuban right-hander is awaiting visa approval, reports Matt Gelb of the Philadelphia Inquirer. Gonzalez reportedly agreed to a six-year, $48MM contract with the Phillies, which could be worth as much as $59MM.
• Gelb also tweeted that Phillies shortstop Jimmy Rollins indicated he is not willing to waive his no-trade clause, if asked.
• There is no indication the Phillies are aggressively taking offers for Chase Utley in the event a contract extension cannot be reached, tweets ESPN's Buster Olney.
• The Braves have not had any conversations with the Royals regarding Ervin Santana, according to Mark Bowman of MLB.com.
• Nationals GM Mike Rizzo told reporters, including the Washington Times' Amanda Comak, he would like to add some more depth before the Trade Deadline. "If we could tweak or improve certain spots on the bench, I think that would be one place that we would attack," Rizzo said. "We’ve got a lot of trade discussions. We’ve received calls, we’ve made calls." 
• Manager Terry Collins doesn't expect the Mets to make any moves prior to the Trade Deadline, reports Kristie Ackert of the New York Daily News. Marlon Byrd is the Met name most mentioned in trade rumors and a team source tells Ackert the asking price is a top 10-15 prospect.
