With no Minor League season, the only time we really get to see prospects is when they get called up to the big leagues. Occasionally, we get a report about a guy performing well at an alternate site, but news coming out of those camps has been sparse, at best.
This week, we want to change that. Reaching out to player development staffs for all 30 teams, we uncovered one prospect for each team who has impressed the most. We might not hear the buzz they are creating all the time, but these 30 prospects are certainly helping themselves with how they've performed, typically against older and more experienced competition.
AMERICAN LEAGUE EAST
Blue Jays: Austin Martin, SS/OF (No. 2/MLB No. 18)
Toronto landed arguably the best all-around hitter in this year's Draft in Martin, taking him with the No. 5 overall pick and subsequently assigning him to the team's 60-man player pool. Though he was announced as a shortstop in the Draft, Martin's athleticism and tools could make him a fit anywhere on the diamond, and his first reps with the organization in Summer Camp were at the hot corner. Overall, Martin has received glowing reviews for his progress at Toronto's alternate site under the guidance of the team's coaching staff.
Orioles: Adley Rutschman, C (No. 1/MLB No. 3)
It shouldn't surprise anyone that the No. 1 pick in the 2019 Draft is performing well during what should have been his first full season of pro ball. He's hit for power while showing above-average plate discipline, and he's been very good defensively behind the plate. The intensity of the work he puts in daily has also rubbed off on other players.
Red Sox: Triston Casas, 1B (No. 2/MLB No. 78)
Though the 2018 first-rounder is still just 20 and hasn't played above low Class A -- where he ranked second in extra-base hits (49) and third in homers (19) in the South Atlantic League in his first full pro season -- Casas has had little difficulty adjusting to more advanced pitchers in alternative camp. The still-growing 6-foot-5, 250-pounder arrived three weeks ago and has stood out with his huge raw power and mature approach.
Rays: Josh Lowe, OF (No. 10)
The 2016 first-round pick began to put it all together last year in Double-A, setting career highs in OPS (.783), home runs (18) and stolen bases (30), and he continued to make strides in the Arizona Fall League before undergoing offseason shoulder surgery that was expected to sideline him for the first half of 2020. But the delayed start to the start to the season enabled the 22-year-old outfielder to make a full recovery without missing any real time, and he's said to be showing well in all facets of the game at Tampa Bay's alternate site in Port Charlotte.
Yankees: Estevan Florial, OF (No. 7)
Florial has some of the best all-around tools in the system, including well-above-average raw power and arm strength to go with plus speed and center-field defense. He could have used a full season of at-bats to iron out his swing-and-miss issues, but he did get to make his big league debut and singled against the Mets in his lone game with New York.
Indians: George Valera, OF (No. 4)
One of the most advanced young hitters in a system full of them, Valera has a pretty left-handed swing as well as the aptitude to recognize pitches and work counts. He posted an .802 OPS as the second-youngest regular (age 18) in the Short-Season New York-Penn League last year and would have made his full-season debut this season.
Royals: Bobby Witt Jr., SS (No. 1/MLB No. 10)
The 2019 Draft's No. 2 overall pick looked like he belonged in big league camp during the Spring and even more so in Royals Summer Camp, where he made several spectacular plays at both shortstop and third base while also showcasing an advanced bat with power to all fields. Royals officials are very impressed with how well the 20-year-old has played around older players at the team's alternate site in Kansas City and are quick to note that Witt Jr. does something to excite them on a daily basis.
Tigers: Riley Greene, OF (No. 4/MLB No. 29)
Greene, the No. 5 pick in the 2019 Draft, was the biggest standout among Tigers prospects in big league camp this past spring, slashing .417/.611/.917 with two homers and six walks in seven games before the season was put on hold. He picked up right where he had left off when play resumed in July and has continued to impress Tigers officials in alternate camp, with the 19-year-old outfielder showcasing a combination of tools and advanced skills belying his age.
Twins: Royce Lewis, SS (No. 1/MLB No. 9)
Lewis had put an up-and-down 2019 behind him when he took home MVP honors in last year's Arizona Fall League. He's continued to make strides at the plate, hitting for average and more power as progress with his lower-half mechanics has paid dividends. He's been playing only shortstop in camp to maximize his reps there and has made some exceptional plays in intrasquad games.
White Sox: Garrett Crochet, LHP (No. 4/MLB No. 98)
Crochet's Draft forecast was a bit cloudy because he came down with mild shoulder soreness and made just one appearance during the shortened college season, but the White Sox had no concerns about his health and were thrilled to grab him with the No. 11 overall pick in June. He has sat in the upper 90s and hit 101 mph with his fastball during alternative camp, and both his slider and changeup can be well-above-average offerings at their best.
Astros: Shawn Dubin, RHP (No. 20)
After playing at three colleges in four years and going in the 13th round of the 2018 Draft, Dubin was a revelation in his first full pro season when he limited opponents to a .547 OPS and 12.3 strikeouts per nine innings, mostly in high Class A. He has continued to open eyes in alternative camp with his nasty slider and 92-97 mph four-seamer while working on upgrading his changeup and command.
Angels: Jordyn Adams, OF (No. 4)
At age 20, he's at the young end of alternate camp participants, but he's stood out. The Angels have seen impressive growth for their 2018 first-rounder over the last 12 months in all facets of the game. Adams is making quick adjustments at the plate and his raw power is starting to show up. His 80 speed plays on both sides of the ball, taking extra bases regularly and showing he has the wheels and instincts to be a premium defender in center field.
