PHOENIX -- The Arizona Diamondbacks are parting with senior vice president of baseball operations De Jon Watson, and chief baseball officer Tony La Russa said he and general manager Dave Stewart may also be fired after the season.La Russa announced Watsons departure after a 10-9 win over the Dodgers on Sunday.La Russa said he will meet with owner Ken Kendrick and president and CEO Derrick Hall eventually about his status.If it gets turned over the next person, you gladly turn it over, La Russa said. When were 20 games under .500, I felt if youre looking at the front office, the most responsible person, it would be me.Arizona made an aggressive push to compete in the offseason by giving Zack Greinke a $206.5 million, six-year free agent contract and trading a bevy of young players to the Atlanta Braves for right-hander Shelby Miller. Greinke is having his worst season in years and Miller pitched poorly enough to get a midseason demotion to Triple-A, part of why the Diamondbacks are just a game out of last place in the NL West at 63-86.When you have this kind of year, Ive never had a problem taking responsibility and evidently, stuff that Ive been taught hasnt contributed enough, La Russa said. Well wait and see how the decision comes. Im ready to go forward if theyve seen enough.Watson was in his second season with the club and oversaw the franchises player development and professional, amateur and international scouting departments.La Russa said the team decided not to renew Watsons contract and let him walk before the end of the season so he can pursue other opportunities.

Manning was the only unanimous choice for the 2013 Associated Press NFL All-Pro team Friday. It might be too little, too late but Port Adelaide rookie Karl Amon reckons his side are starting to deliver some of their best football.Despite a finals berth looking increasingly unlikely, the Power kicked the highest score of the 2016 AFL season in Saturdays 25.23 (173) to 11.13 (79) thumping of Brisbane.Amon, who has played 11 games in his second AFL season, says the emphatic win showed what the Power are capable of when firing.The style we played, we got back to Port Adelaide football, he said on Wednesday.(We were) tough inside and then really took it on the outside which was good to get back to.The 20-year-old midfielder, who gathered 15 touches and booted two goals at the Gabba, described the 94-point victory as his best game of the season.But he admitted hee had lacked consistency throughout his second year in the AFL.ddddddddddddI think thats always been my weakness, he said.Ill always go missing for maybe a quarter in the game.Thats something were trying to work on. I think its just working on little things in your game that you can improve on (and) staying involved.Already three wins shy of eight-placed North Melbourne, Port face one of the AFLs toughest road tests when they take on Sydney at the SCG on Saturday.Amon said Ports hard-nosed midfielders would relish the opportunity to test themselves against the Swans, who are ranked number one in the competition for contested possessions.
