Perhaps one of these days -- when he throws a no-hitter or throws the final pitch of a pennant-clinching victory for the Nationals -- Stephen Strasburg will offer up the kind of display of emotion few have ever seen from him.
For now, there's very little that can happen on the field to break through the stone-faced visage of a 23-year-old right-hander who expects the very best from himself and isn't about to publicly celebrate his accomplishments.
Strike out seven of 10 batters over a four-inning stretch? Nothing. Club the first home run of your career and be summoned by an overflow crowd of 41,918 for a curtain call? Just give a quick tip of the cap. Find out your manager revealed you were were dealing with some kind of arm trouble? The exterior expression still doesn't change.
"I just think that's his thing," teammate Danny Espinosa said. "He doesn't show emotion, and that's good. If things are going good or bad, there's no emotion shown, which to me is an even-keeled guy."
There were other important developments during the Nats' 9-3 victory over the Orioles Sunday afternoon in the finale of this series. Bryce Harper overcame an early error to deliver the two-run triple that ignited a sleeping lineup. Jesus Flores mashed only his second big-league homer in three years. Espinosa produced two of his biggest hits in weeks.
At the end of the day, though, the spotlight once again shined brightest on the pitcher who has been under the brightest spotlight since the day the Nationals drafted him three summers ago. For plenty of reasons, some positive, some potentially negative.
Through it all, Strasburg stayed calm and determined. He wasn't fazed by a shaky couple of innings to begin his afternoon, when the Orioles scored three runs (two unearned) and jumped out to an early lead that left many wondering whether Strasburg was about to endure through another outing too similar to his previous laborious appearance five days earlier against the Padres.
He simply retired 10 straight batters, striking out seven to silence the Orioles' potent lineup.
"It was almost like deja vu, especially after what happened the previous game," he said. "I wanted to go out there and do a better job of not letting that affect how I attack hitters. It was nice to be able to go out there and adjust from it and keep the team in the ballgame long enough for us to put some runs on the board."
Unlike that game against San Diego, the Nationals stormed back and got Strasburg off the hook. Though he was just as influential in making that happen as anyone in the lineup.
It was Strasburg's leadoff single in the third that set in motion a three-run rally. And then one inning later, he pulled off his most extraordinary feat yet.
Behind in the count 0-2 to Baltimore left-hander Wei-Yin Chen, Strasburg decided to sit on a curveball. He got one, and the force of his swing sent shockwaves throughout the park.
The ball sailed toward left field, sending Xavier Avery back to the fence. Eventually, the Orioles outfielder ran out of real estate and could only watch as the ball landed in the visitors bullpen, then as Strasburg strolled around the bases on a 26-second victory lap following the first home run of his career.
"Shocking," Strasburg admitted. "That's for sure."
He, of course, was being modest. Those who watch Strasburg hit on a regular basis knew this might happen some day.
"Oh, we watch him all the time; it's a display," first baseman Adam LaRoche said. "I think Ryan Zimmerman was joking: He needs to start in the All-Star Game and hit in the Home Run Derby. It's pretty impressive."
Throughout his stroll around the bases, Strasburg never showed any out-of-the-ordinary emotion. He didn't pump his fist. He didn't even appear to smile until he finally returned to the dugout and a few teammates began to rib him.
"I think Strasburg just expects to hit," Espinosa said. "He's a good hitter. He's a good athlete. I don't know, I don't think too much really affects him."
Perhaps not even some arm soreness that may or may not have been significant. Manager Davey Johnson surprisingly volunteered that Strasburg told him following the fifth inning that his right biceps muscle was tight. His pitch count already at 90, Johnson just decided to shut him down for the day.
"His tightness was in his bicep, and he said it was bothering him," the manager said. "Early on, he thought he could get it loose and keep going, but it seemed to get tighter on him. And as soon as I heard that, I said that was it."
Strasburg insisted he had no such issue in his biceps, only the typical kind of fatigue he feels after pitching.
"I wouldn't say it was just my arm," he said. "I think it was just my body."
Strasburg attributed the issue to his having overworked himself in the days since his last start. Perhaps wanting too much to bounce back from a four-inning loss, he did more extensive weight-lifting and throwing in the days since and paid the price for it Sunday when he took the mound.
"Nothing different than any other outing," he reiterated. "It's something that it's going to be like this for probably the rest of the year. It's just part of coming back from Tommy John surgery, building up the innings, getting the stamina and everything. It's something I've just got to be smart about."
Red flags might be waving across town now, but both Johnson and Strasburg insisted he'll make his next start -- currently scheduled for Saturday in Atlanta -- and that there is nothing to be concerned about moving forward. Given Strasburg's history and the manner in which the Nationals have taken extreme precautions with their former No. 1 pick, few would be surprised if the plan changes.
If this is actually something serious, Strasburg certainly wasn't letting on Sunday. He remained his usual self in the postgame clubhouse, chatting with teammates, watching highlights of his performance on MLB Network and eventually showering and dressing for the team's short bus ride to Philadelphia.
For now, he was concerned only with the job he did to help his team snap a three-game losing streak and avoid a sweep at the hands of the Orioles.
That's Strasburg's job, and he's very serious about it.
"To be completely honest, I'm the type of person I want to take ownership," he said. "I want to take charge. I want to be that guy they can rely on to get the job done. At times, I feel like I have to do more to go out there and get the team back on track. And a lot of it's out of my control. I have to go out there and try to do my job. And if everybody does their job, we're going to be OK."
