Just missed Top 30: Mitch Longo
Longo doesn't have any "wow" tools but he does have good feel for hitting and enough power, speed, arm strength and defensive ability to profile as a useful fourth outfielder. A 14th-round pick out of Ohio in 2016, he batted .275/.337/.410 with eight homers and 18 steals in Class A Advanced in 2018.

On the shelf
Right-handers Triston McKenzie (upper back strain), Nick Sandlin (forearm soreness) and Aaron Civale (lat issues lingering from 2018) are beginning the season in extended spring training and should report to Akron when healthy in the near future. Second baseman Richie Palacios is on the injured list at Lynchburg while recovering from shoulder surgery.

Impact prospect: Oscar Mercado
Acquired last summer from the Cardinals in exchange for a pair of outfielder prospects, Mercado impressed in his first Spring Training with Cleveland, finishing with a .400/.415/.750 line and three homers in 40 at-bats. Though mostly known for his speed and defensive ability in center field, the 24-year-old also has some untapped potential at the plate that he could realize in 2019.

Breakout prospect: George Valera
Signed for $1.3 million in July 2017, Valera carried plenty of hype into his pro debut and got off to a strong start in the rookie-level Arizona League, only to have his season end after six games due to a broken hamate bone in his hand and subsequent surgery. The injury has done nothing to diminish the 18-year-old outfielder's upside, and scouts continue to rave about Valera's gorgeous left-handed swing as well as his ability to apply his power during games at a young age.

Best defensive prospect: Eric Haase
Haase reached the Majors for the first time late last season, seven years after the Indians took him in the seventh round of the 2011 Draft. Though he's blossomed on both sides of the ball during the past two seasons, it's been Haase's defensive gains that have helped him climb the Tribe's depth chart. After throwing out 37 percent of attempted basestealers in 2017, Haase improved that mark to nearly 49 percent in '18 (33 of 68).
