My God Father Willie is very happy for you as well.— Barry L Bonds (@BarryBonds) May 2, 2015As with most things A-Rod, the home run has become a flashpoint between player and team. The Yankees don't want to pay Rodriguez the $6 million bonus he's due for reaching 660, a sum negotiated when Rodriguez signed a 10-year, $275 million contract with the Yankees in 2007. The team reportedly believes Rodriguez's 2013 suspension for violating baseball's drug policy has destroyed its ability to market the feat. The Yankees have ignored the chase to 660 in its pregame media notes.    Rodriguez could file a grievance if the Yankees try to not to pay him. He made sure not to get caught up in any of that Friday night."Those things will take care of themselves," he told reporters. He was much more willing to acknowledge his role in the Yankees' 14-9 start to the season.  "A year ago today I never thought I'd be hitting home runs and helping the Yankees win. Being in the middle of it is fun again," he told reporters.
