Game 119 lineups: Nats at Padres (Madson to DL, Kelley activated)

SAN DIEGO - Hello from Petco Park, where it's a spectacularly perfect day. Shocking, I know, considering we're in San Diego.

The Nationals open a seven-game road trip with the first of four here against the Padres, the undercard I suppose for next week's series in Houston against an excellent Astros club. The Padres are not excellent; they rank last in the majors, scoring 3.88 runs per game, and 23rd in the majors, allowing 5.08 runs per game.

The Nats, of course, have boasted the National League's most productive lineup all season, but it should be noted that their production has dropped off of late. They've scored an average of only 3.2 runs in their last five games, which just happen to coincide with Bryce Harper's injury. Small sample size, obviously, but it is going to be tough to make up for Harper's loss, however long it is.

Edwin Jackson, who made 13 starts for the Padres last season, gets the ball tonight. I'd say he'll be motivated against his former team, but even Jackson admits he's pitched for so many teams over the years that he's motivated against all of them.

Update: The Nats have placed reliever Ryan Madson on the 10-day disabled list with a sprained finger and activated reliever Shawn Kelley from the 10-day DL.
