One prospect from every MLB team who could have an impact on the 2019 season

When health has been his ally, Duplantier has been undeniably dominant, posting a 1.39 ERA in his first full pro season in 2017. A battle with biceps tendonitis in 2018 limited him to 74 innings capping at Double A last year. Following a promising showing in the Arizona Fall League, Duplantier could position himself for a shot with the D-backs if he can prove his durability in the rotation this spring.

Of the many pitching treasures in the Braves system, Toussaint could have the most electric stuff. He had a cup of coffee in Atlanta last summer but has a clear shot to stick coming out of camp this year. Toussaint held MLB foes to a .182 average against as a 22-year-old and possesses as electric of a fastball-curveball combination as any emerging talent in the game.

Diaz was the centerpiece return from the Dodgers for Manny Machado last July and has quickly become an exciting part of Baltimore's near future. The 22-year-old spent 2018 in right field between the Baltimore and Los Angeles systems and has the type of power potential that could stick there. With the barren condition of the Orioles roster, Diaz could easily break through to the majors with a strong start to the year.

In many other systems, Chavis’ pathway to the majors would be an easy one to foresee. But with the depth of the defending World Series champs at both corner infield positions, Chavis may have to wait for an injury opportunity to make his way up. The club could also look to try him at second base, as his power (40 home runs since 2017) could be a definite benefit at the position.

The Cubs system has been greatly depleted by the club’s many "win now" trades of recent years, leaving few immediately projectable impact players. Luckily for Joe Maddon and Co., Alzolay remains on hand, possessing the type of mid-90s fastball that could at the very least make for an electric bullpen arm this summer.

Jimenez has been ready to crack the majors since last summer but was left behind in a contested decision based in extending his contractual obligation. The moment the club gets its extra year secured, expect Jimenez to materialize immediately on the South Side. His prodigious power potential is on the Giancarlo Stanton-Aaron Judge level, but he is far from a one-trick pony, hitting .337 over 108 games at the Double- and Triple-A levels last season.

Cincinnati is hungry to find a way to get Senzel’s plug-and-play bat into its lineup. The presence of a pair of All-Stars in Eugenio Suarez and Scooter Gennett is currently blocking him at both his natural position (third base) and his adopted one at second. Until a path clears, the team is prepared to try him in center field to gift his bat to the lineup, as Senzel’s upside as a potential future batting champion is needed now amid the Reds' rebuild.

With a quad injury sidelining Francisco Lindor to open the year, Chang has a chance to fill in for the franchise backbone until he returns. If the power he showcased at Triple-A Columbus carries over (13 home runs, .741 OPS), along with his ability to play multiple infield positions, he could stick even after Lindor’s return.

Rodgers' deliberate ascent since being selected third in the 2015 draft could finally reach a head this summer, as a place in the Colorado infield has finally presented itself with the departure of DJ LeMahieu. His approach at the plate could use some final touches, but Rodgers’ exceptional bat speed and versatility across the infield will make him yet another impressive (and versatile) homegrown asset for the Rockies.

Son of former Gold Glove outfielder Mike Cameron, Daz was one of the main returns from the Astros in the Justin Verlander trade of two years ago. In the time since, Cameron has flashed the same penchant for manning the outfield that his father did and has plus speed as well, topping 20 stolen bases in three of four pro seasons. With the Tigers in full-blown rebuilding mode, the opportunity will present itself for Cameron to crack the majors as a 22-year-old.

There is no more electric, exciting pitcher who will debut in the majors this summer than Whitley. He stamped this in an Arizona Fall League performance, leading the superstar prospect circuit in strikeouts. Able to already unleash four pitches he can create outs with, Whitley has averaged 13.3 strikeouts per nine innings as a pro. It is a blend of upside and results that projects him to be this year’s Walker Buehler, as a supremely talented prospect able to instantly amplify one of the game’s best teams.

The Royals boasted the American League’s worst bullpen a year ago, holding a 5.04 ERA and allowing a .279 average against. These are two areas that Lovelady specializes in. He posted a 2.47 ERA and converted nine saves while holding opponents to a .204 average against at Triple-A Omaha. With a strong spring, he should have the chance to head north with the big league club and grow into a late-inning option.

Canning blew through the Angels organization in his first full pro season, making 13 Triple-A starts. Typical of polished college pitchers, Canning possesses a mature approach and arsenal on the mound, able to call on his breaking balls with confidence already. With the rash of injuries that have regularly haunted the Angels starting staff, Canning’s rapid rise could quickly continue with him reaching Anaheim this summer.

Verdugo can just plain hit, so much so that the Dodgers were easily able to move on from Yasiel Puig and Matt Kemp with him waiting in the wings. He has splattered 52 MLB at-bats across parts of 2017 and 2018 but looks primed to take on a much bigger role this summer. An owner of an .811 minor league OPS and .309 average, Verdugo looks the part of the next left-handed young stud in Dodger blue.

Alcantara has one of the most electric arms in the game, with a fastball that regularly lives in the high 90s. The Marlins can afford to be patient with his development, even at the major league level, where he rang out 10 strikeouts in fewer than 100 pitches in his final start of 2018. With a strong spring, there is a chance that he could even position himself as a candidate for Opening Day duties.

Arizona Fall League MVP Keston Hiura will get much of the buzz among the Brewers prospects, but it is Brown who could have the clearest path to Milwaukee this summer. He went 9-1 with a 2.44 ERA at Double-A last summer and could easily fit himself into a Milwaukee rotation that opted against looking for external upgrades this winter.

The native Australian was finally healthy and able to deliver on his long-standing promise in 2018, notching eight wins across two levels. He also racked up 157 strikeouts over 129.2 innings, thanks to an impressive fastball for a lefty. With the Twins amid another rebuild, Thorpe could easily amplify that effort this season.

Alonso swings an easy, natural and reliable bat. Overall, he connected for 36 home runs between the two highest levels of the minors in 2018 before adding another six in the Arizona Fall League. He is clearly the Mets' first baseman (and perhaps DH) of the future, and the future is now. Alonso is making an impression in spring training and should only have the contractual control demotion back to the minors before joining the Mets early in the year.

Despite missing three years of his young pro career already between shoulder issues and Tommy John surgery, Loaisiga still has a fastball that lives in the mid-90s with the ability to go higher. He also has starter potential despite the fact his track record seems to indicate that a bullpen assignment might be the safer route.

The best left-handed pitching prospect in the minors, Luzardo’s talent is ready for the Oakland rotation already at 21 years old. He did run into some opposition at the Triple-A level after blowing past Double- and Single-A competition, limiting batters to a .162 average against and a 0.86 WHIP. Luzardo’s lively fastball and advanced change-up are both well beyond minor league proof points and will join Oakland’s push to make a return to October baseball.

Haseley had a coming-out party in 2018, a year after being the eighth pick of the 2017 draft. He produced a .316/.403/.880 split after being promoted to Double-A Reading while increasing his power numbers in the process (six home runs) and flashing an impressive glove in center field. His defensive prowess could be his calling card, as he could be a needed addition between the veteran corner outfield combo of Andrew McCutchen and Bryce Harper.

The Pirates have developed an impressive group of prospects on the brink of breaking through to help their MLB group, including Mitch Keller and Ke'Bryan Hayes. However, the position that is most prone for a prospect breakthrough is shortstop, where Tucker has thrived of late. He stole 35 bases at Double-A last summer, before hitting a sizzling .370 in the Arizona Fall League — earning him a spot on the 40-man roster.

There’s nothing more for Tatis Jr. to prove. He is baseball's best all-around prospect. He has torn through the competition early in spring training, and his teammate Manny Machado immediately moved back to third base upon signing in San Diego. If everything goes as it projects, Tatis will be the next to join the incredible class of shortstops in the game today…and start moving toward its elite rungs.

Alexander’s stock has risen constantly over the last year, making an appearance in the All-Star Futures Game last summer while averaging a strikeout per inning at Double-A Richmond. Anderson eventually made eight starts at Triple-A Sacramento, where he will likely need a bit more time to start the year. But when the inevitable opening comes in the Giants rotation, Anderson will be on the short list to be called upon to fill it.

Sheffield was the centerpiece return in the November trade that sent James Paxton to the New York Yankees, and for good reason. The young left-hander pounds the zone with a fastball that has made him one of the elite strikeout pitchers in the minors. It is a habit he should easily carry over to the majors, where he should join the Mariners early in 2019.

Reyes’ long-promised dominant arrival has been delayed twice in the last three years, first by Tommy John surgery in 2016, then by a torn back muscle in his 2018 return the majors. Before his most recent derailment, Reyes dominated during his rehab stint, striking out 44 over 23 innings while allowing only seven hits and zero runs. In some capacity, he stands to be a potent weapon among manager Mike Shildt’s deep pitching ranks — good health willing, of course.

Honeywell’s anticipated rookie debut in 2018 was thrown off track by Tommy John surgery last spring. He is slated to be back by May, giving him a chance to join the Rays for the second half of the season. A polished pitcher with a wide-spanning arsenal highlighted by an ever-so-rare screwball, Honeywell could be a prime candidate to join Kevin Cash’s creative pitching staff usage in a variety of capacities.

One of the hardest-throwing lefties in the game, Hearn has the raw stuff to make it to the majors this year. Yet as he continues to refine his secondary offerings and control, he could be best leveraged initially as a high-octane reliever in the MLB. If he does show strides in either area, Hearn could quickly pierce the Rangers’ patchwork veteran rotation.

Arguably the most famous prospect of all time for much more than his name, in all reality, Vlad Jr.’s bat was MLB-ready a year ago…if not earlier. Instead, he was left to feast on overmatched minor league pitching, which he spent much of the summer hitting over .400 against before finishing at .381 with a ridiculous 1.073 OPS over 357 at-bats. From the day he puts on the Blue Jays cap, he will be the team’s best player and could easily hit his way into an All-Star appearance this summer.

A year after Juan Soto’s run as a rookie phenom, Robles is in position to carry that torch for the Nats next. A gifted five-tool performer with speed to burn, Robles is a top-flight athlete who showcased a sampling of his talents in a 21-game cup of coffee last year and profiles as a prototype No. 2 hitter. His game-changing speed makes him an instant impact defender in center field with limitless range and the upside to reach 30-plus stolen bases regularly.
