Series finale underway on a gorgeous, 66-degree September Sunday in Pittsburgh, where the locals surely are way more invested in this game than any other taking place right now in the sports world.

And there's a leadoff homer for CJ Abrams off an 0-2 pitch from Jared Jones. That's one way to get this thing started.

Joey Bart drives a Patrick Corbin cutter to left for a 2-run homer. Nats down 2-1 in the 1st.

Pirates are all over Corbin in the 1st. Five of their first seven batters have recorded hits, including 25-year-old rookie Billy Cook, who just notched a 2-run double in his first career AB. Nats down 4-1.

Jacob Young continues his hot streak with another opposite-field hit, this one a 2-out RBI single. Nats down 4-2 in the 2nd.

Longtime Nat killer Andrew McCutchen still doing it. No-doubter to left off Patrick Corbin. It's 5-2 in the 3rd.

Luis García Jr. thought he had a play at the plate. He did not. Everybody's safe, and the Nats' deficit is now 6-2 in the 4th.

10 in a row retired by Jared Jones. Nats don't have a hit since Jacob Young's RBI single in the 2nd. They trail 6-2 in mid 5th.

13 in a row retired by Jared Jones, who is through 6 innings on 78 pitches.

Michael A. Taylor takes Patrick Corbin deep for his 100th career homer, bringing out all kinds of various emotions from Nats Twitter, I'm sure. Pirates up 7-2 in the 6th.

Patrick Corbin was going to throw 100 pitches today, no matter what. He wound up throwing 102 pitches over 6 innings, allowing 7 runs. It's the 5th time he's given up 7+ runs this season. His ERA is up to 5.60.

16 in a row retired by Jared Jones, who is through 7 innings on 92 pitches.

19 in a row retired by Jared Jones and Jalen Beeks. The boys are not really battling today.

Well, now the boys are trying to battle in the 9th. Wood leadoff single, Chaparro RBI double cuts it to 7-3.

Final: Pirates 7, Nats 3. CJ Abrams hit a leadoff homer, then Patrick Corbin gave up 4 runs in the bottom of the 1st and 7 overall during a 6-inning start necessitated by the bullpen's work during yesterday's doubleheader sweep.

Patrick Corbin was going to throw 100 pitches today, no matter the total number of innings or runs. One day after Davey Martinez pushed his bullpen to the max to secure a doubleheader sweep over the Pirates, it was time to pay the bill. And the Nats paid. masnsports.com/blog/corbin-ta…
