From Comcast SportsNetST. LOUIS (AP) -- Rookies in the postseason, the Washington Nationals played like poised veterans.The Nationals escaped a bases-loaded jam in the seventh inning, pinch hitter Tyler Moore blooped a two-out, two-run single in the eighth and Washington beat the defending World Series champion St. Louis Cardinals 3-2 Sunday in an NL playoff opener.The Nationals, who had never come close to making the playoffs since moving from Montreal for the 2005 season, overcame a wild start by 21-game winner Gio Gonzalez.Reliever Ryan Mattheus needed just two pitches to bail out the Nationals in the seventh with St. Louis ahead 2-1. Tyler Clippard worked around an error in the eighth and Drew Storen saved it with a 1-2-3 ninth.The NL East champion Nationals led the majors with 98 wins this season, and brought postseason baseball to Washington for the first time since 1933. The Nats go for a 2-0 series lead Monday when Jordan Zimmermann opposes Jaime Garcia.The Cardinals made it to the best-of-five division series by beating Atlanta in the wild-card matchup Friday. But St. Louis wasted a 10-strikeout gem by Adam Wainwright, failing to capitalize enough on Gonzalez's career high-tying seven walks and frustrating its towel-waving fans.A standing room crowd of 47,078, among the largest at 7-year-old Busch Stadium, bundled up for a game that began in 54-degree chill and featured kaleidoscope late-afternoon shadows that bedeviled hitters for several innings.Rookie shortstop Pete Kozma misplayed Michael Morse's grounder for an error to open the eighth and set up the Nationals' go-ahead rally.

He's been a postseason ace with a microscopic 0.77 ERA and 32 strikeouts in 23 1-3 innings.He fanned Bryce Harper and Ryan Zimmerman twice each and seventh-place hitter Espinosa all three times.Gonzalez allowed just one hit in five innings, on David Freese's full-count bouncer between third and short to start the fourth. But he had trouble finding catcher Kurt Suzuki's glove.The second inning was Gonzalez' shakiest when he allowed the Cardinals to score twice and take the lead without a hit. Gonzalez walked four of the first five hitters, putting St. Louis in position to score one run on a wild pitch and a second on Jon Jay's bases-loaded sacrifice fly.Nationals right fielder Jayson Werth robbed Daniel Descalso of a two-run homer off with a leaping catch to keep it at 2-1 in the sixth. Descalso had a fielding gem of his own in the seventh, ranging far to his left to glove Harper's grounder and then throwing him out by a few steps.
Christian Arroyo homered on the first pitch of the eighth inning to propel the Giants over the Padres in the series opener.
Selection: Third round, No. 104 overall
SANTA CLARA -- The 49ers traded back into the end of the third round to select a quarterback to join Brian Hoyer and Matt Barkley on the 49ers' roster.
General manager John Lynch's fourth trade of the draft netted the team the grandson of legendary NFL personnel man Bobby Beathard. His grandson, C.J., joins the 49ers after a four-year career at Iowa. Beathard completed 58.6 percent of his passes last season with 17 touchdowns and 10 interceptions.
Beathard was not generally expected to be chosen within the first two days of the draft. He was the sixth quarterback selected, falling behind Mitch Trubisky, Patrick Mahomes, Deshaun Watson, Deshone Kizer and Davis Webb.
"They won't regret it," Beathard said on a conference call with the Bay Area media.
The 49ers traded up with the Minnesota Vikings. The Vikings had the No. 104 pick, and called the 49ers to see if they were interested in a trade. After some consideration, the 49ers decided to move up from No. 109 while also giving the Vikings a seventh-round pick at No. 219.
"Might he have been there at 109? That’s what we had to weigh," 49ers John Lynch said. "But at the end of the day, we felt like it was worth it to be able to go to bed knowing that we had a player that we liked and want the opportunity develop at the quarterback position."
And that's what coach Kyle Shanahan plans on doing. He said Beathard is not coming to the team this season to compete with Hoyer for the starting job.
"We’re bringing him in here to develop him and give him a chance, but just like any other position, everyone competes," Shanahan said. "Brian is our starting quarterback and, right now, Matt Barkley is our second. And I look at him to come in and be our third with us only having three on the roster.
"By no means did we come into this draft thinking we’re going to get a guy to compete with Brian."
Shanahan said Beathard and Pitt quarterback Nathan Peterman were the two quarterbacks in the draft who ran offenses in college most similar to the offense he will install with the 49ers.
"One thing that helps is being able to see guys play the way you’re going to ask them to play," Shanahan said. "It helps being at Iowa and watching the system he’s in. It’s easier to see to watch him over the years. He’s a three-year starter. He’s led his team to a bunch of wins, especially in 2015 when they had a better team and he played unbelievable."
As a junior at Iowa, Beathard completed 61.6 percent of his pass attempts for 2,809 yards with 17 touchdowns and five interceptions.
"He’s a leader. He’s tough. He processes very well," Shanahan said. "He's extremely accurate and he lives and dies football."
