That's now the number of times the Pirates have had this season to sweep opponents and failed to do so. This game, it was the struggles of starting pitcher Bryse Wilson that doomed the Pirates in a 6-2 loss to the Nationals Sunday afternoon.
It was the third straight start Wilson has been knocked around a bit and until those starts, Wilson had been largely consistent in going out and getting the job done in each start.
"I think we've seen definite growth in terms of ability to attack the strike zone and ability to execute pitches," Pirates manager Derek Shelton said following the game.
