The Nationals, according to a report from FOXSports.com's Ken Rosenthal, have reportedly agreed to pick up Papelbon's 2016 contract, but at a rate less than the $13-million that he was guaranteed. They have reportedly also guaranteed Papelbon that he will supplant Drew Storen as the team's closer, which was another concession that Papelbon wanted from any team that acquired him.
Washington was on Papelbon's no-trade list, but waived his right and accepted the trade rather than stay in Philadelphia.
Pivetta has pitched in 18 games - 17 of them starts - this season between stints with High-A Potomac and Double-A Harrisburg. Pivetta has struggled in his three starts with Harrisburg, his first at the Double-A level, posting a 7.20 ERA, but his last start, he allowed just two earned runs over five innings, although he did walk five batters, while striking out three. In all, he's walked nine and struck out six at the Double-A level over 15 innings.
Pivetta opened the season with the High-A Potomac Nationals of the Carolina League and was 7-4 with a 2.29 ERA in 15 games, including 14 starts. In 86 1/3 innings with Potomac, he walked 29 and struck out 72.
The Phillies have not announced where they will assign Pivetta.
While there has been no official word, Ken Giles figures to take over as the closer for the Phillies. Papelbon had converted all 17 of his save opportunities with the Phillies this season. Over three-plus seasons in Philadelphia, Papelbon blew just 15 of 138 save opportunities and posted a 2.31 ERA.
