Miami Marlins morning news: Marlins top prospect stabs teammate

Marlins News:

Marlins number two prospect Josh Naylor stabbed Class-A Greensboro Grasshopper teammate Stone Garrett in an apparent prank that went wrong. Garrett, who is the Marlins' top prospect of 2015 will be out for an unknown amount of time as he is recovering from three stitches to his right hand. There is no word yet as to if Naylor has been punished for the off-the-field incident.

Miami is undecided about re-signing third baseman Martin Prado since the emergence of Derek Dietrich, and the fact that the 26-year-old Dietrich could become the third baseman of the future for the Marlins with the numbers he has put up so far in the 2016 campaign.

While meeting with the media, Don Mattingly reflected on Muhammad Ali and the time he spend with him.

Marlins righty Brian Ellington, who was recently called up from Triple-AAA, credits reliever Craig Breslow for turning him around. Ellington struggled early on in the season with Triple-AAA New Orleans, walking 18 batters in 15 innings, but since taking Breslow's advice, his fortunes have taken a turn for the better.

Around the League:

Outfielder Carl Crawford was designated for assignment by the Dodgers on Sunday. Los Angeles is on the books for the $35 million owed to him on his contract that runs through 2017. The transaction is justified, as Crawford hit an abysmal slash line of .185/.230/.235 in 81 at-bats this season, and he wasn't receiving much playing time, as manager Dave Roberts has opted to give Trayce Thompson, Scott Van Slyke, Joc Pederson, Yasiel Puig, and Enrique Hernandez more playing time.

The Yankees aren't planning on trading anyone yet, but that might all change in July, per Jon Heyman.

Even though top Yankees executives are saying they aren't looking at selling, Ken Rosenthal of Fox Sports reports that the Giants are thinking about pursuing reliever Andrew Miller. Miller would be a great fit in San Francisco, as they look to make a push into the playoffs, an experienced left-handed reliever would bode well for manager Bruce Bochy and his team's hopes of winning another Fall Classic.

As the White Sox have found themselves contenders in the AL Central, they looked to bolster their pitching staff, and they did just that over the weekend, acquiring Padres pitcher James Shields in exchange for starter Erik Johnson and MiLB shortstop Fernando Tatis Jr.
