Spring Training isn't the time to be watching superstars. Sure, it's fantastic news that we get to see Bryce Harper and Mike Trout in live game action two weeks from now. But -- as long as they stay healthy -- how they perform during camp is of little consequence.

There are, however, plenty of players worth your attention as Spring Training progresses -- whether they're youngsters fighting for jobs or veterans recovering from injuries.

Here's a look at the most critical player for each team this spring.

AL East

Blue Jays: Aaron Sanchez
The Toronto lineup is loaded, but its pitching staff could desperately use another front-line starter. Sanchez's stuff would indicate he has that capability -- but is he ready to handle that kind of workload? At 23, Sanchez clearly has a much higher upside than Drew Hutchison or Jesse Chavez, but the Blue Jays may end up deciding he's worth the most to them out of the bullpen.

Orioles: Kevin Gausman
Gausman has shown flashes of brilliance for three seasons, but he hasn't been able to put it all together. In many ways, 2016 is a make-or-break season for the 25-year-old right-hander.

Rays: Blake Snell
The 14th-ranked prospect by MLBPipeline.com, Snell is coming off a brilliant season in which he progressed from Class A Advanced Charlotte to Triple-A Durham and went a combined 15-4 with a 1.41 ERA. That was good enough to earn him Baseball America's Minor League Player of the Year Award -- an award with an illustrious history. Chances are, Snell starts the season at Triple-A. But if he's particularly dominant this spring, the Rays might be forced to find room for him.

Red Sox: Hanley Ramirez
Ramirez has played precisely zero big league innings at first base in his career, but the Red Sox fully expect him to open the season as their first baseman. It'll be a transition worth watching, as will Ramirez's attempts to improve his output at the plate.

Yankees: Starlin Castro
Castro has played plenty of second base, so his transition won't be quite the same project. But there are plenty of nuances he still needs to pick up. Spring could also give us a good indication of which Castro will resurface at the plate -- the one from the first half of 2015 (.247/.283/.321) or the second half (.295/.319/.464).

NL East

Braves: Ender Inciarte
Inciarte quietly hit .303/.338/.408 last season, before joining the Braves as part of the Shelby Miller trade. And while Atlanta received some seriously talented prospects in that deal, none of them will break camp with the club. Inciarte, meanwhile, has two very good seasons under his belt, but still has five years of team control remaining.

Marlins: Carter Capps
Capps was one of the best relievers in the game, until he went down with an elbow injury last August. If he's back and healthy, he could develop into one of the game's elite closers. Plus, his funky (and very much legal) delivery is always worth watching.

Mets: Michael Conforto
Conforto got his first crack at the Majors last year, but for the most part, the Mets sheltered him. Only 14 of his 174 big league at-bats came against left-handed pitching. Now, Conforto will transition into an everyday role, and his ability against left-handers will be a major storyline for New York this spring.

Nationals: Trea Turner
Turner is quite clearly the Nationals' shortstop of the future, but that doesn't make him a shoo-in for the job out of camp. He'll have to earn it by proving himself this spring. The Nationals, who figure to be in a dogfight for the NL East, can't afford to allow Turner any growing pains on the job.

Phillies: Aaron Nola
Nola's debut in 2015 was largely a success (6-2, 3.59 ERA). But this spring, he won't be playing the role of rookie on the rise. The Phillies could very well ask Nola to be their ace, and if he starts on Opening Day, he'd become the club's youngest pitcher to start an opener, at just 22 years old.

AL Central

Indians: Michael Brantley
Brantley probably won't partake in any Spring Training games, but that doesn't mean he isn't worth keeping an eye on. In fact, Brantley's recovery from November shoulder surgery is the single most important storyline out of Indians camp -- and thus far, the news is all good.

Royals: Christian Colon
After his postseason heroics in 2014 and again in '15, Colon is already a folk hero in Kansas City -- which is a bit strange, considering he's only had 168 career plate appearances. Omar Infante is the clear favorite for the second-base job, but Colon could make his own case with a big spring.

Tigers: Justin Verlander
Spring results won't matter for Verlander as much as what's happening with his pitches. Does his fastball still touch the mid-90s? Is he locating it low in the zone? Are his breaking pitches missing bats? If the answer is yes to all three, we could be set to see a return to form for Verlander, who struggled (largely due to injuries) over the past two seasons, but posted a 2.48 ERA and a 0.99 WHIP last August and September.

Twins: Byron Buxton
Long considered one of the game's best prospects, Buxton finally gets his chance to secure a starting job. The 22-year-old struggled (.209/.250/.326) in his 46-game big league stint last season -- but then again, so did Trout when he was called upon briefly in 2011.

White Sox: Carlos Rodon
The White Sox will have a hard time competing in 2016 without a big season from Rodon, who made his debut in '15 and put some filthy stuff on display. Is the former No. 3 overall pick ready to become a complement to Chris Sale atop the rotation? We may start to find out.

NL Central

Brewers: Orlando Arcia
The Jean Segura trade seemingly paved the way for Arcia to take over at shortstop, but new general manager David Stearns has already made it clear he plans to begin the season with Arcia in the Minors. The club's top prospect might not stay there long, especially if he puts forth a solid spring, proving he can hit big league pitching.

Cardinals: Carlos Martinez
We already know what Martinez is capable of. He's got an electric fastball and a killer curveball, against which opponents batted just .172 last season. But is Martinez fully recovered from the shoulder injury that ended his season last September? That will be the key question for St. Louis this spring -- and the answer could make all the difference in the Central race.

Cubs: Jorge Soler
Soler's potential remains mostly untapped, after an ankle injury sidelined him for a chunk of 2015. But Soler, who turns 24 next week, went 9-for-19 with three doubles and three homers in the playoffs last year, and it'll be interesting to see whether he can carry that success over to the '16 season.

Pirates: John Jaso
The Pirates are one of the most complete teams in baseball, but first base has long been an issue. To combat that, they signed Jaso, one of the game's most underrated on-base threats. The only problem? Well, Jaso has only played four games at first base. A smooth transition will be of paramount importance for Pittsburgh.

Reds: Robert Stephenson
This should finally be the year Reds fans get to see highly touted pitching prospect Stephenson make his debut. It's simply a matter of when. On a club in the midst of a full-blown rebuild, hey, why not give Stephenson a shot to prove himself big league-worthy this spring?

AL West

A's: Jarrod Parker
Everyone is rooting for Parker, who was in the process of recovering from his second Tommy John surgery last season when he fractured his elbow. He's worth watching as a (hopefully) feel-good comeback story, but more importantly to see how the A's plan to use him. A move to the bullpen would make sense, but the club has reiterated its plan to give him a chance to crack the rotation.

Angels: Andrew Heaney
There might not be a pitcher with a bigger range of potential Spring Training outcomes. If Heaney continues to progress from his solid rookie campaign, he could begin the season as the Angels' second best starter. If he struggles, he could find himself getting more experience in the Minors, given the Angels' plethora of rotation options behind him.

Astros: Doug Fister
If Fister reverts to his 2014 form, the Astros will have gotten themselves the steal of the offseason. Fister's velocity has been in decline for a while now, but until a forearm injury in '15, he was able to counteract that with his sinker. If Fister can limit opponents' hard contact this spring, it should be a sign of good things to come for Houston.

Mariners: Taijuan Walker
Walker began the 2015 campaign 1-5 with a 7.33 ERA over his first nine starts, but settled in and actually recorded a solid second half by improving his command. The Mariners want to contend in '16, and Walker might have to take the next step in order for them to do so. But first he'll have to earn his rotation spot -- which isn't a guarantee.

Rangers: Joey Gallo
Is there room for Gallo on the Rangers' Opening Day roster? Well, he could force the Rangers' hand with a massive spring. Gallo, the No. 9-rated prospect in all of baseball, boasts big league-ready power, but he'll need to prove he can cut down on swings and misses and take a few more walks.

NL West

D-backs: Yasmany Tomas
A year ago, the D-backs committed $68.5 million to Tomas, making him the seventh-highest paid free agent in a relatively strong class. With Arizona having dealt Inciarte to Atlanta, there is now a clear opening in right field for Tomas to slot into an everyday role. Even with their busy offseason, the D-backs need a lot to go right in 2016 if they plan on winning the West. A breakout season from Tomas would certainly help.

Dodgers: Corey Seager
Just about every major outlet has Seager listed as baseball's top-rated prospect. He proved himself in a small sample size last year, but his first full season figures to be a memorable one.

Giants: Angel Pagan
The Giants acquired center fielder and leadoff hitter Denard Span in the offseason, which leaves Pagan's role somewhat in question. But with a strong spring -- offensively and defensively -- Pagan could reclaim both of those jobs, provided he can stay healthy.

Padres: Austin Hedges
Hedges struggled in his much-anticipated debut season, batting just .168/.215/.248 in 56 games for the Padres. No one questions his defensive prowess -- Hedges is an elite backstop. But his offensive game will need to improve if he's to become San Diego's catcher of the future (and it appeared to be doing so during a brief stint in the Dominican Winter League).

Rockies: Jon Gray
The Rockies' longtime top pitching prospect, Gray will be given every opportunity to break camp in the starting rotation. His debut was a bit of a flop (0-2, 5.53 ERA in nine starts during 2015). But that experience could prove pivotal, as he was afforded an entire offseason to prepare for big league hitters.
