Rowan County’s young American Legion team brought out the brooms on Tuesday night and made it a clean four-game sweep over Lexington in the second round of the Area III Southern Division playoffs with a 6-2 win.

Rowan (23-7) has won 14 straight games overall, a total which includes seven consecutive playoff victories. Rowan breezed past Mocksville three straight last week to get the postseason under way.

The toughest opponent for Rowan over the next few days will be rust. The team is going to take two days off, then get back to work Friday and Saturday to prepare for the Division championship series against Concord or Stanly County. That series will open Sunday night at Newman Park.

‘‘We’re playing very well right now and every single one of these kids is contributing,’’ said Rowan coach Jim DeHart. ‘‘I know everyone will work hard the rest of the way.’

‘‘You get this far in the playoffs and no one wants to let down,’’ agreed Rowan second baseman Nathan Woodburn, who had three hits and stole four bases in the clincher. ‘‘We’re going to keep on pushing.’’

It was Rowan pitcher Jesse Boger who gave Lexington (14-16) that last push out the playoff door at Holt-Moffitt Field last night.

Boger pitched what may have been the best game of his career – Legion or high school. He went all nine innings, striking out 12 and walking three. He allowed only four hits. Only one ball – Andrew Harrison’s double in the sixth inning – was stung off Boger the entire game.

Boger is generally considered Rowan’s No. 4 pitcher – no insult on a staff that includes Daniel Moore, Brian Hatley and Chad Walker.

Maybe that explains why Boger’s contributions often get overlooked.

Every Rowan fan knows that Moore hasn’t lost a game since May 19 (Stanly), that Hatley hasn’t lost since May 22 (Mooresville) and that Walker hasn’t lost since June 4 (Wilmington). That trio has been great during Rowan’s run. But heck, give Boger a little credit, too. He hasn’t lost at all.

Boger (4-0) started the game like he intended to take an early shower. After three batters, he’d issued two walks (one more than Hatley had handed out the whole game on Monday night) and surrendered a base hit. And Lexington, of course, had the bases full with no outs.

And DeHart, of course, was making his way from the dugout to the mound.

‘‘I wasn’t headed out there to tell him to throw strikes,’’ explained DeHart. ‘‘That’s something negative and I never go out to the mound to say negative things. I just wanted to talk to Jesse about his concentration. There was nothing wrong with his arm. It was all in his head.’’

It was catcher Brad Canipe, who figured out why Boger’s concentration was wavering. A college scout armed with a radar gun had taken a perch right behind the plate, and Boger, like a lot of pitchers have done before him, was overthrowing trying to make a favorable impression with his velocity.

‘‘Give Brad credit for being observant,’’ said DeHart.

A rather animated conversation between DeHart and Boger ensued. DeHart rotated his arms, kicked the dirt and did a lot of tapping with his finger on his noggin.

And Boger got the message about the radar gun.

Boger is successful not because of how hard he throws. He doesn’t blow people away like Moore. But what he does have is good control, a nasty slider and the ability to change speeds.

Those things are enough to get batters out and impress scouts.

After his ‘‘chat’’ with DeHart, Boger kept Lexington off the scoreboard with two strikeouts and a fly ball to right fielder Brett Peiffer.

‘‘I was off to a little bit of a rocky start,’’ said a sheepish Boger. ‘‘Coach was a little upset and excited. But he got me to settle down. And then I got out of the inning.’’

Rowan slowly built a lead for Boger.

Eddie Guessford drove in Cal Hayes Jr. in the first inning – going with a 3-and-2 pitch to right-center for a clutch, two-out single.

In the fourth, Woodburn singled in Peiffer, who had walked and then pulled off one of Rowan’s nine stolen bases, to make it 2-0.

‘‘It’s playoff time,’’ said Woodburn, who had been slumping when the series began. ‘‘And that means it’s time to step up. The ball just looked bigger than usual.’’

It was 3-0 after the fifth when Hayes scored a weird run when Canipe struck out with the bases loaded and two outs, but Lexington catcher Patrick Truluck couldn’t catch the ball cleanly, and then couldn’t make a play anywhere.

Lexington, which hadn’t gotten a hit off Boger since the first, got things stirring in the sixth inning. Harrison’s double, an RBI groundout and a couple of singles suddenly made it 3-2.

Things had gotten messy for Jesse, but he bore down and kept it right there.

‘‘Jesse did a good job of what I call damage control,’’ said DeHart, pleased that Boger had defused a potential big inning. ‘‘That’s something we talk to our pitchers about a lot.’’

Rowan made it 6-2 in the seventh with some help from Lexington’s defense. Hatley and Walker walked and Peiffer singled to make it 4-2. Then an error loaded the bases for Woodburn. He hit a comebacker, but Lexington reliever Phillip Shoaf, who could have come home, instead rifled a fastball into center field to plate two Rowan runs.

Boger had looked weary in the sixth, so DeHart had Moore up and getting loose in the seventh and eighth.

But Boger didn’t need any assistance. In fact, he set down the last nine Lexington hitters without a whimper.

‘‘Coach kept asking me if I wanted to stay in, and I kept saying, ‘Yeah,’|’’ said Boger. ‘‘It was important to me to finish, because I’d never pitched a nine-inning, complete game before.’’

Now he has.
