Last season turned out to be the best of Strasburg's career by most measurements, as he posted full-season career-bests in ERA (2.52), WHIP (1.02) and WAR (5.6), while topping 175 innings for the first time since 2014. He lost nearly a month to a nerve impingement in his right elbow during the second half, but he closed out the regular season with a 63:10 K:BB, 0.84 ERA and 0.78 WHIP in 53.2 innings over his final eight starts after returning from the DL, and was dominant in two playoff starts against the Cubs. As expected, Strasburg reduced the use of his slider in 2017, opting to throw more curveballs with the hope of reducing the wear and tear on his elbow. Since the start of the 2013 campaign, Strasburg has averaged just under 170 innings annually, but his cumulative workload during that five-year span ranks him 30th in MLB (848.1 IP). Once again, the talent will make him a top-10 starting pitcher in most drafts despite the ongoing concerns about his health.

For two tantalizing, fleeting months to begin the year, it looked like Strasburg was finally going to put it all together. He won his first 10 decisions, posted a filthy 11.1 K/9 and 4.3 K/BB in 106.2 first-half innings, and surprisingly took himself out of the 2017 free agent market by signing a seven-year, $175 million extension at the beginning of May. Then he missed a month with an upper back strain, and when he got back on the mound in June, the magic was gone. A brutal outing in Coors Field in August led to a seemingly inevitable DL stint due to elbow inflammation that effectively ended his season, and his final line was much the same as it had been in 2015, featuring a stellar strikeout rate that didn't seem to be in sync with a merely good ERA and WHIP figures over fewer than 150 innings. Strasburg's arsenal remains exceptional, with a 95 mph fastball contrasting with a devastating high-80s changeup and low-80s curve, but the slider he threw 17.1 percent of the time was blamed for his latest injury issues, and he vowed to throw it far less in 2017.

Dubbed "The Orchid" (awesome, but fragile) by ESPN's Tony Kornheiser, Strasburg has had six DL stints in a six-year career, including two in 2015. Seen as the second coming on his way up, he’s logged just one 200-inning season. Yet despite the drawbacks, he’s unquestionably elite when he does pitch. Aside from ERA indicators like FIP, which suggest he was great in 2015 (2.81), even the most basic measurements point to something special with an 11.0 K/9 and 1.8 BB/9. A non-cancerous growth was removed from Strasburg's back after the season, and it may very well have contributed to his injury issues in 2015, including a strained neck from late May. It’s hard to put him in the class of aces with multiple 200-inning seasons, but his skills say he’s right behind them. The cost will be lower in 2016, too.

While it wasn't the breakout season his owners were likely expecting, Strasburg's 2014 was still his most successful to date, in no small part due to the fact that he managed to stay healthy. His 215 innings pitched and NL-leading 242 strikeouts (tied with Johnny Cueto) were career bests, as was his 1.8 BB/9 rate. Although his 3.14 ERA wasn't exactly elite, he certainly didn't hurt owners in that category, and his 1.12 WHIP actually landed him in the NL's top 10. Strasburg's arsenal (94-97 mph fastball, absurd high-80s changeup, and knee-buckling low-80s curve) still makes scouts drool, but he's finally showing signs of adding some savvy to his repertoire as well. Given that he won't turn 27 until mid-2015, there's little reason to think that he's hit his peak already. Health willing, top-tier ratios to match his strikeout rate should be on their way sooner rather than later.

Oh, the agony of being a Stephen Strasburg owner. He tossed a career-high 183 innings in 2013, with a plus strikeout rate, ERA and WHIP, yet somehow managed to win just eight games. He had an injury scare to boot, although the eventual culprit seemed to be nothing more than bone chips in his elbow. All the tools are there for him to be among the game's elite pitchers, but until he actually strikes out 200 batters or wins 20 games in a season, there are going to be question marks. Of course, those same question marks could make Strasburg a relative bargain in 2014 if he does finally put it all together.

Despite his team-mandated innings cap, Strasburg still returned ace-like numbers, winning 15 games and striking out nearly 200 batters with solid ratios. He may only be scratching the surface though. His .311 BABIP seems ripe for a drop given his ridiculous stuff, and without the distraction of a workload restriction the 24-year-old could improve in areas like groundball and walk rates. He still needs to prove he can handle a full season's workload of course, but that lack of a track record is the only thing keeping him from being the first starter off the board come draft day.

Strasburg spent most of 2011 rehabbing from Tommy John surgery, but did manage to throw 24 innings with the Nationals as a part of that process. As expected in the first year, Strasburg’s velocity was not all the way back to his 2010 level, but he did average 95.3 mph and touched 99 mph on occasion. Additionally, he cut his breaking ball usage in half, which contributed to fewer swinging strikes. However, his control was impeccable, as he walked only five in 44.1 innings. Look for him to come back strong in 2012, but there will be some bumps along the way as he attempts to regain his elite status.

The Double-S Express did everything he could to make everyone happy in his rookie season. He graced a few minor league parks with his presence and put on a dominating show, sliced through big league lineups after his callup like a 97-mph fastball through butter to prove that all the hype wasn't out of line, and then broke down to make all the naysayers who lobbed Mark Prior comparisons his way feel all full of themselves. Tommy John surgery wasn't the worst possible outcome as injuries go, though, and while he'll likely miss all of 2011 his projected future rotation-mate Jordan Zimmermann made it back in about a calendar year, so there's a chance Strasburg will be back on the mound in September. Don't fret too much if the Nats treat him with kid gloves in his rehab, though. This is a kid who posted an absolutely insane K/BB ratio of 5.41 in his first crack at the majors. In keeper leagues, he's worth waiting for.

Set aside the hype for a minute and look at what the Nationals actually got for their first overall pick and $15 million dollars. Strasburg hits triple digits on radar guns with regularity, has a plus curve and a changeup which is already OK even though he barely needed to use it in college, knows where the ball is going when he throws it, and has the big-game mentality to go out and rack up a 17-K no-hitter in his final home start for San Diego State. His inability to stay healthy in his Arizona Fall League stint is a bit worrisome, but none of the injuries were serious or directly arm-related and he'll have all winter to heal. The Nats have indicated they aren't going to rush him, and considering the state of the team they certainly have no reason to, but given what he could already do on the mound as a 20-year-old "not rushing him" could mean keeping Strasburg out of the major league rotation all the way until May. The specter of Mark Prior hangs over him (there are some similarities in their mechanics) but even Prior had a couple of very good big league seasons before breaking down, so at least in the short term if there were even such a thing as a can't miss pitching prospect, Strasburg would be it.
