CHICAGO (AP) — Jeff Samardzija thought he would dominate the way he often does. Instead, he walked away frustrated with another loss.
Samardzija struggled in a rare rough outing and the Chicago Cubs lost 7-2 to Washington, completing a day-night doubleheader sweep on a rainy Saturday night.
Nationals left-hander Gio Gonzalez pitched two-hit ball over seven innings in the opener for a 3-0 victory. In the night game, Washington tagged Samardzija (2-7) for six runs — five earned — and seven hits over five innings to salvage a four-game series split.
"I felt really good out there today, which usually means you're going to pitch deep into a game," said Samardzija, who has a 2.83 ERA. "When that doesn't happen, usually you get a little frustrated."
He gave up a leadoff homer to Adam LaRoche in the second on a long drive to right, and Wilson Ramos went deep to start the fifth, sparking a four-run rally that made it 6-2.
That sent Blake Treinen (1-3) to his first career win in his fifth major league start. The right-hander allowed two runs and four hits in five innings after being recalled from Triple-A Syracuse as the 26th man on the roster for the doubleheader.
Ramos connected on the first pitch of the fifth for his second homer, and Washington sent up nine batters in the inning.
With two outs and a man on first, three straight singles by Anthony Rendon, Kevin Frandsen and Jayson Werth resulted in two more runs. First baseman Anthony Rizzo then let LaRoche's hard smash get by him for an error, bringing in Frandsen to make it 6-2.
"Coming out of the rain delay they jumped on me right off the bat, and then they hit some fastballs over the plate and hit them up the middle," Samardzija said. "Made me keep throwing pitches. Like I said, they did a good job. They were ready out of the break."
In the first game, Gonzalez dominated in his third start back from the disabled list, outperforming Dallas Beeler in the righty's major league debut.
Rendon had three hits, including a two-out double against Beeler in the sixth before scoring the game's first run on a wild pitch. Rendon added an RBI triple off Justin Grimm and came home on a sacrifice fly by LaRoche against Wesley Wright in a two-run eighth.
Gonzalez (5-4) struck out seven and walked two while improving to 2-0 in three starts after missing a month because of inflammation in his pitching shoulder.
Tyler Clippard worked the eighth and Rafael Soriano finished for his 19th save in 21 chances.
"Obviously, coming (off) the DL and trying to work your way back is going to be a process," Gonzalez said. "It's not going to happen overnight. It's good to see, little by little, using fastball and changeup at the same time. It's good to know when you need them they'll be there."
Beeler was about as good as Gonzalez. Called up from Triple-A Iowa as the 26th man, he pitched four-hit ball while allowing an unearned run in six innings.
Beeler also singled in his first at-bat when he lined the first pitch he saw up the middle in the third, drawing big cheers from the crowd.
"I was a lot calmer than what I thought I'd be," he said. "I walked out there, took a deep breath, threw my warmup pitches, kind of looked around again, exhaled and I was like, 'All right, same game I've been playing for the last 20 years.'"
NOTES: The Cubs have their first scheduled Sunday off in 82 years because of the annual Pride Parade in Chicago. The last one was on June 19, 1932. Chicago played the Giants in New York on a Saturday and then visited Philadelphia on a Monday.
