7:30pm: According to MLB.com's Bill Ladson, the Phillies haven't talked to the Nationals about Kennedy.
1:31pm: The Phillies learned today that Chase Utley will be out for several weeks due to thumb surgery, and Ken Rosenthal of FoxSports.com chimes in with some possible replacement options. He notes that the replacement doesn't necessary have to be a second baseman (Twitter link), because the team can use Placido Polanco at that position once he's healthy. That opens up the possibility of a trade for a third baseman.
Rosenthal says that former Phillie Pedro Feliz is an unlikely target, citing a scout who says his bat speed is "gone." Feliz has hit just .229/.255/.317 in 255 plate appearances this year, and his trademark defense has declined back to a -4.3 UZR this season. The Fox Sports scribe throws the names of Miguel Tejada, Ty Wigginton, Jhonny Peralta, Adam Kennedy, and Jose Lopez into the mix (Twitter links). The Mariners are actively trying to move Lopez, according to Rosenthal.
For the now, Philadelphia will try to tread water with the combination of Wilson Valdez and Greg Dobbs at second and third, respectively. They've combined to hit just .222/.252/.338 in 222 plate appearances this season, and Jack Moore at FanGraphs chronicled just how big of a downgrade this is for the Phillies.
