Taijuan Walker surrendered seven runs — six earned — in 4 2/3 innings versus the Nationals on Monday.

Walker gave up 10 hits despite allowing just five hard-hit balls. Even more incredible is that three of those were outs; the Nats were 7-for-11 with a sac fly on their softer contact. Still, this is the kind of thing that’s going to happen from time to time when you can’t miss bats. The poor showing gives Andrew Painter an early edge when it comes to determining who stays in the Philadelphia rotation after Zack Wheeler returns, though we’ll see what Painter can do Tuesday. Walker will face the Rockies in Coors Field on Sunday.
