The San Francisco 49ers have their first win of the 2017 season after downing the New York Giants, 31-21, in Week 10. San Francisco's offense was dominant throughout Sunday's contest, posting 474 total yards behind a monster performance from C.J. Beathard.

The game wasn't as close as the score indicates. A garbage time touchdown from the Giants made it a 10-point margin. New York took a 13-10 lead in the second quarter before San Francisco went on a 21-0 run.

Here are Sunday's top takeaways as the 49ers have plenty of good vibes going into their bye week.

**

1.** Beathard was masterful on Sunday, completing 18-of-25 passes for 288 yards, two touchdowns and one interception. The rookie added five carries for 15 yards and his third rushing touchdown of the season. It was Beathard's first-career multi-touchdown performance.

San Francisco's first touchdown came midway through the second quarter with the 49ers trailing 6-3. Beathard found Marquise Goodwin wide open down the middle of the field for an 83-yard score. Pierre Garçon had a key blitz pickup to allow Goodwin time to get downfield.

Just before the half, Beathard hit Garrett Celek for a 47-yard touchdown. Celek picked up a block from Goodwin and outran the rest of the Giants defense. It was the longest catch of the tight end's career.

Beathard found the end zone himself on an 11-yard touchdown run on the first play of the fourth quarter.

The rookie's only blemish was an interception in the red zone. Beathard tried to find Hyde on a screen pass, but Olivier Vernon made a leaping play of the pass and picked it off. Outside of that, Beathard was an absolute stud.

2. A consistent running game provided ample support for Beathard. Hyde posted 98 yards on 17 carries. Matt Breida added nine carries for 55 yards, including a 33-yard touchdown run. It was Breida's first-career rushing score. Hyde said a few weeks back that the motto of the 49ers running backs' room is "everybody eats". They'll enjoy watching the tape of this one.

3.** Eli Manning and the Giants offense moved the ball consistently, but San Francisco's defense never broke completely. New York went scoreless from the 2:08 marker in the second quarter, all the way to the 1:08 mark in the fourth quarter. Reuben Foster posted a game-high 10 tackles and was very active throughout.

4. San Francisco's defense got three sacks against Manning. Ronald Blair III was responsible for two of them, one of which was a sack/fumble. Eric Reid recovered the loose ball for the 49ers lone takeaway of the game. Elvis Dumervil also got a sack and now has a team-high 4.5 on the season.

5. There's no overstating the importance of having Joe Staley back in the lineup. Beathard wasn't sacked on Sunday and was hit just twice. That's a stark contrast to the 16 hits he took a week ago against the Arizona Cardinals. The 49ers entire offensive line, in addition to the tight ends and running backs, was fantastic in pass protection.

6. The 49ers didn't sustain any injuries on Sunday, which was a welcomed sight after the carnage the team has suffered the past two weeks. Beathard did bang his right thumb during his touchdown run. He was tended to by the medical staff on the sideline but never missed a snap.

7.** Sterling Shepard was the only Giants playmaker to do significant damage against San Francisco's defense, catching 11-of-12 targets for 142 yards. Shepard made the play of the game on a one-handed catch down the left sideline.

8. Kyle Juszczyk was used heavily in the passing game. The fullback caught 5-of-6 targets for 27 yards. Juszczyk did lose a fumble for the second straight week.

9. Kendrick Bourne and Louis Murphy also had big moments in the win. The newly-signed Murphy caught a 40-yard pass. All three of Bourne's receptions helped the 49ers convert on third down. He finished with three catches for 42 yards.

10. Here's the stat of the game: The 49ers offense went 8-of-12 on third down. That's a recipe for success and illustrates just how much of a rhythm Shanahan was in as a playcaller on Sunday. Shanahan dialed up the right plays and in the right moments while the players executed to near perfection.
