Postgame analysis of the Nats' 10-2 win over the St. Louis Cardinals on Sunday afternoon at Nationals Park.
How it happened: Sometimes in baseball all it takes is a second look at a pitcher and on Sunday the difference between the Nationals' first run through the lineup and their second against Cardinals starter Michael Wacha was quite significant.
For the first three innings, the Nats were held hitless, the only baserunner earned on a walk to Wilson Ramos. But then in the fourth, things quickly devolved for Wacha. The Cardinals right-hander gave up two hits to lead off the frame, the second to score a run. He then allowed a two-RBI single to Ramos with two outs.
The three runs in the fourth off Wacha gave them the lead, but a five-run seventh inning put this one on ice for the Nationals. Anthony Rendon led off with a solo homer and Jayson Werth cleaned up the rest with a pinch-hit grand slam. It was Werth's sixth career grand slam, his first ever as a pinch-hitter and his first pinch-hit homer of any kind since 2007. It was also just the second pinch-hit grand slam in Nats' history following Justin Maxwell's in September of 2007. You don't see them very often.
Ramos then added a two-run homer in the eighth to make it 10-2. It was Ramos' third hit of the day.
Ten runs were more than enough help for Stephen Strasburg and the Nats' bullpen. Strasburg gave up one run on a homer to Brandon Moss, but otherwise limited damage throughout the afternoon with six hits and two walks spread across six strong innings. Strasburg now has the best start in franchise history at 9-0.
The Nats' bullpen ran into some trouble in the seventh with a bases-loaded jam with one out, but Felipe Rivero escaped the frame with just one run allowed and a lead intact. The run came on a sac fly by Matt Adams, but all things considered, it could have been much, much worse.
What it means: The Nationals closed their homestand on a positive note as they get set for an 11-day road trip, which is tied for the longest one they have this season. They also finished their season series against the Cardinals with a 5-2 record. That's a nice change of course after they went 8-18 against them from 2012 through 2015.
Rendon smacks homer No. 4: Rendon added an insurance run in the eighth inning with a solo home run to right field on the first pitch he saw from reliever Jonathan Broxton. After having zero homers in April, Rendon has four this month. He has reached safely in 20 of his last 22 games. In 18 games going back to May 10, Rendon is 24-for-63 (.381) with two homers, six doubles, a triple, 10 RBI, 12 walks, 11 runs and three steals. He posted his 10th multi-hit outing of that 18-game stretch. Even taking Saturday night off did not cool him down.
Ramos hits No. 6: Ramos reached base four times on Sunday with a walk and three hits in three at-bats. He hit a two-run bomb to left field in the eighth inning, his sixth homer of the season. Ramos is now batting .336 through 40 games this season.
Zimmerman gets another XBH: After going 4-for-4 with two homers on Saturday night, Zimmerman notched another extra-base hit on Sunday with his double in the fourth inning. Zimmerman now has 10 doubles on the season and 14 extra-base hits in May after posting just four in April. The problem for Zimmerman has been consistency this season in putting together more than two solid games in a row. Just last week he had two hits in consecutive games on May 23-24, then went hitless in four straight outings. On May 10 he had two homers, but that was during a stretch where he went 5-for-37 across nine games. It has truly been feast or famine for the Nats' first baseman this season.
Harper drives in a run: Harper's RBI single to score Michael Taylor in the fourth inning gave him his fourth straight game with a hit. He also has an RBI in five of his last eight games despite only having four hits during that stretch. Harper has scored a run in four straight outings. Overall, though, it was another frustrating day for Harper, who went 1-for-4 with a strikeout. After he popped out in the sixth, he was shown on a television replay chucking his batting helmet in the dugout.
Strasburg left in, then pulled: Strasburg's exit after six innings was part of some creative managing for Dusty Baker. He sent Strasburg out to start the seventh after 104 pitches, but then brought in Oliver Perez before Strasburg even threw a pitch in the inning. He called on Perez once Cardinals manager Mike Matheny brought in Kolten Wong as a pinch-hitter. And once Matheny saw Perez come in, he replaced Wong with Aledmys Diaz to pinch-hit. There was a pitching change and two pinch-hitters inserted into the game all before a single pitch was thrown. The Nats, by the way, have now won all 11 of Strasburg's starts this season and 15 in a row dating back to 2015.
Up next: The Nats embark on a long road trip beginning with three games in Philly. They play three at the Phillies, then three at the Reds and White Sox. Monday night will be a 7:05 p.m. start with Tanner Roark (3-4, 2.71) set to pitch opposite Phillies right-hander Jeremy Hellickson (4-3, 3.97).
