Mitchell Parker is starting for the Nationals in game 2 of the double header and he is 7-9 with a 4.27 ERA in his rookie season. He has been inconsistent all season, even allowing 4 runs in his last start, and he has been much worse on the road as well. He allowed 9 earned runs in his last road start, his worst start of the season, and he has allowed at least 5 earned runs in 2 of his last 3 as well as at least 4 earned runs in 3 of his last 5 road starts. Mitch Keller is starting for the Pirates in this game and he is 11-9 with a 3.88 ERA this season. He has not been great recently, allowing 3 earned runs in each of his last 2 starts, but he has been much better at home throughout the season and will be hungry to bounce back in this game. He has allowed 2 earned runs or less in 3 of his last 4 home starts and has not allowed more than 3 earned runs in any of those starts either. The Pirates have the more consistent starter to lean on in this game at home and they have been playing well recently as well. The Pirates will win this 2nd game of the double header.
