Postgame analysis of the Nats' 5-3 loss to the San Francisco Giants on Saturday evening at AT&T Park.
How it happened: Mark Melancon can't join the Nationals soon enough.
On the same day the Nats pulled off a big trade for an upgrade at closer, it was their bullpen that failed them. Yusmeiro Petit allowed the go-ahead run on a sacrifice fly to Joe Panik in the bottom of the seventh inning. Panik killed the Nats in the 2014 NL Division Series and on Saturday he was the hero in a 5-3 Giants win.
The trouble, though, didn't stop there. After Petit left, Blake Treinen walked Trevor Brown with the bases loaded to score another run. That gave the Giants the comfort of a two-run lead. The Nats' bullpen had made things interesting in the first two games of their series at San Francisco and they finally cracked in the third matchup.
Rookie Reynaldo Lopez allowed the Giants' first three runs and only lasted four innings. Giants starter Jake Peavy also had a short day with three runs given up in four innings of work.
Anthony Rendon launched a two-run homer in the third inning. Danny Espinosa landed an RBI double in the fourth. Trea Turner went 2-for-4 with a steal. Ryan Zimmerman continued to heat up with a single and a run. Jayson Werth extended his streak of reaching base end to 33 games on a bloop single in the eighth inning.
The Nats, though, went 0-for-7 with runners in scoring position. Three of those at-bats came in the first inning after Turner led off with a single, then stole to reach second. The Nats could not move him from there.
What it means: The Nationals had their three-game winning streak snapped with the loss and fell to 2-1 against the Giants this season. They sit 61-43 on the year.
Lopez struggles again: Lopez has all the tools to be a very good MLB pitcher, whether that's as a starter or a reliever, but through two outings he has not had much luck. In his debut against the Dodgers it was basehits that killed him. On Saturday, he couldn't command the strike zone and ended up with five walks in addition to four hits.
Lopez was better in his second start than he was in his debut, but still found trouble getting batters out. He escaped a major jam in the second inning when Eduardo Nunez popped out with the bases loaded. Lopez was not as fortunate in the bottom of the fourth when Nunez doubled with the bases juiced to score two runs. The other run off Lopez was on an Angel Pagan groundout in the same inning.
Joe Ross made another rehab start with Triple-A Syracuse on Saturday. If he is not ready to return to the Nats' rotation in five days, it will be interesting to see if they go back to Lopez or give Lucas Giolito another shot.
Caught stealing: The Nats had two runners caught stealing by Buster Posey. One was Ben Revere in the fifth inning with Hunter Strickland on the mound. The other was in the seventh with Sergio Romo pitching. Harper's was a tough one, as he led off the frame with a walk with the Nats looking to come back from a two-run deficit. The Nats right fielder had no chance against Posey, who easily threw him out on the attempt. Werth then singled two at-bats later, leaving the Nats only to wonder what could have been.
Rendon hits No. 13: Rendon has been the Nats' best hitter this month not named Daniel or Wilson, and the third baseman kept it going on Saturday with another big game. Rendon's homer was his 13th of the season and his sixth of July. Over his last 11 games, Rendon is 14-for-42 (.300) with four homers, eight RBI and six runs scored.
Up next: The Nats and Giants close out their series with another 4:05 p.m. start on Sunday. Gio Gonzalez (6-8, 4.44) will look to keep his positive momentum going opposite Matt Cain (2-6, 5.95).
