Now Rizzo acknowledges: ‘‘We had a pretty good feeling he was ready.’’
By Harper’s fifth game, Johnson moved him to No. 3 in the batting order. He later settled into the second spot, behind Jayson Werth and in front of Ryan Zimmerman, and flourished.
Harper’s 254 total bases and 57 extra-base hits are the most ever for a player under 20, while his 22 homers, 98 runs, .340 on-base percentage, .447 slugging percentage, and .817 on base-plus-slugging are all the best for a teenager in the past 45 years, according to STATS LLC.
‘‘He’s pretty good right now,’’ Philadelphia Phillies manager Charlie Manuel said, ‘‘but he’s going to be better. ... He looks for ways to beat you.’’
It’s important not to get too caught up in the notion that Harper is tremendously successful for a teen. As Washington pursued its first NL East title down the stretch, he was among the best in baseball, no matter the age.
From Sept. 1 through the end of the regular season, the left-handed-hitting Harper — he throws right-handed, but swings lefty because he wanted to be like his older brother, Bryan, who’s a southpaw — led all NL players in runs (27), and ranked in the top eight in the league in slugging percentage (third, .643), batting average (tied for fifth, .330) and on-base percentage (eighth, .400).
‘‘He’s pretty much got, in his mind, a bulletproof shield around him at all times,’’ Nationals first baseman Adam LaRoche said. ‘‘We see stuff every two or three days from him that’s just like, ‘Wow. I haven’t seen that in a long time.'’’
In one game last month, Harper made an over-the-shoulder catch to end one inning and, moments later, drove a ball that hung barely above the dirt the opposite way for an RBI double. Apparently picked off second because he strayed too far off the bag, Harper bolted for third and wound up with a stolen base.
Two days later, he threw someone out at home to get one standing ovation, then earned another when a runner held at third because of the threat of Harper’s throwing ability.
That same week, Harper slammed against the wall to catch an inning’s third out and, on second base in the bottom half, took off for third on a changeup in the dirt — even though the ball stayed near the plate. Perhaps stunned, the catcher threw the ball into left field, letting Harper score.
There’s plenty more where that came from, including Harper’s first steal in the majors, back in May. Phillies pitcher Cole Hamels plunked him on purpose; Harper moved to third on a teammate’s single, then swiped home when Hamels made a pickoff throw to first.
‘‘He’s always going 100 mph,’’ Rizzo said, ‘‘with his hair on fire.’’
Sometimes it feels as though Harper does something noteworthy every day — on or off the field.
Like the time he batted against the Reds with blood streaming from a gash above his left eye, which later needed 10 stitches, because he hurt himself slamming a bat against a wall on an 0-for-5 night. Or when his uniform belt snapped on a dive for a liner against the Mets, and Harper found himself hustling over to Washington’s bullpen to get a loaner. Or, most famously of all, when Harper — who is, of course, too young to legally drink alcohol in the United States, and also is Mormon — was asked by a reporter whether he has a favorite beer.
‘‘I'm not answering that,’’ Harper replied. ‘‘That’s a clown question, bro.’’
So was born a phrase that took off on Twitter and spawned T-shirts that Harper and Zimmerman each sported in the Nationals Park clubhouse in recent days.
The brashness that used to raise questions about Harper now draws praise.
‘‘He’s come a long way. I was in spring training with him last year, and to see the changes he’s made, both physically and the mental side of it — he’s grown up a ton. He’s now got the respect of all his teammates and we all back him 100 percent,’’ LaRoche said.
‘‘A lot of people on the outside, if they’re watching a guy like Bryce and only see him once a month, it might be like, ‘Man, that’s kind of tired. He’s going 1,000 miles an hour on a ball hit back to the pitcher?’ But when you see it every day — that’s the only way he knows how to play the game,’’ LaRoche added. ‘‘If we’re down three or four runs and Bryce turns a routine single into a double, it can fire some guys up. It’s motivating. He’s been a spark plug since the day he got up here, and I don’t think that'll ever change.’’
Johnson likes that about Harper, too.
‘‘He’s really not a kid; he’s a man,’’ Johnson said, unveiling his toothy grin before delivering the punch line. ‘‘But he’s a kid to me.’’
