Felix Hernandez and the Seattle Mariners are working on a $175 million, seven-year contract that would make him the highest-paid pitcher in baseball, according to a person with knowledge of the deal's details.

Seattle would add $134.5 million of guaranteed money over five years to the contract of the 2010 AL Cy Young Award winner, whose current agreement calls for him to receive $40.5 million over the next two seasons.
The agents who represent Seattle Mariners catcher Jesus Montero and Toronto outfielder Melky Cabrera say no one at their agency has ever heard of or knows anyone at the Florida anti-aging clinic currently under investigation by Major League Baseball.
Arizona has traded outfielder Justin Upton to the Atlanta Braves in a seven-player deal that sends former All-Star infielder Martin Prado to the Diamondbacks, a person familiar with the situation said Thursday.

The Braves also get third baseman Chris Johnson. Atlanta is giving up four minor leaguers in the deal, including top pitching prospect Randall Delgado. The other minor leagues headed to Arizona are right-hander Zeke Spruill, shortstop Nick Ahmed and first baseman Brandon Drury. Prado can become a free agent after this season.

The Nationals also received minor-league right-hander Blake Treinen from the A's and will get a player to be named from Oakland in the deal, which also sent catcher John Jaso from Seattle to Oakland.
The Mariners added some much-needed power to their lineup Wednesday, acquiring Michael Morse from Washington in a three-team deal that moved catcher John Jaso from Seattle to Oakland.
