Three Orioles prospects named to Baseball America’s top 100 list

January 24, 2019 | Luke Jones

The Orioles remain in the early stages of what’s expected to be a long rebuild, but the farm system isn’t completely bare for new general manager Mike Elias.

Outfielder Yusniel Diaz, left-handed pitcher DL Hall, and third baseman Ryan Mountcastle were named to Baseball America’s top 100 prospects list released Wednesday. It was the second straight year in which three Baltimore prospects were included in the publication’s preseason list.

Acquired from the Los Angeles Dodgers as the centerpiece of the Manny Machado trade last July, Diaz ranked 37th on the list after batting .285 with 11 home runs, 15 doubles, 45 runs batted in, and 12 stolen bases in 416 plate appearances at the Double-A level last season. The 22-year-old Cuban outfielder also posted a .392 on-base percentage and .449 slugging percentage.

Diaz homered twice in the MLB All-Star Futures Game just days before being traded to the Orioles, but he struggled with his new organization, hitting just .239 with a .732 on-base plus slugging percentage in 152 plate appearances for Bowie. His speed and arm give him the ability to play all three outfield spots, and the organization hopes his uptick in power during his age-21 season will continue into 2019.

Ranked 54th in Baseball America’s top 100, the 20-year-old Hall was Baltimore’s first-round pick in the 2017 draft and thrived in his first full professional season, posting a 2.10 ERA in 94 1/3 innings at low Single-A Delmarva. The lefty averaged 9.5 strikeouts per nine innings and allowed only 1.17 walks and hits per nine innings. His mid-to-low 90s fastball and curveball are considered plus pitches while Hall continues to refine his changeup, giving him a high ceiling in an organization long criticized for its inability to produce quality starting pitching.

Mountcastle is on the preseason list for the second straight year, dropping from No. 71 in 2018 to 90th this year. That drop is no reflection of what the 21-year-old did at the plate for Double-A Bowie, batting .297 with 13 homers, 19 doubles, 59 RBIs, and an .806 OPS in 428 plate appearances. Few doubt the 2015 first-round pick’s ability to hit at any level, but questions remains about where he’ll fit defensively after he was already moved from shortstop to third base in 2017. An organization source predicted last fall that Mountcastle would end up at first base, but Elias and the new regime will have the chance to make their own assessments.

The trio also appeared on the Baseball Prospectus top 101 prospect list released earlier this week with Diaz at No. 44, Mountcastle ranking 51st, and Hall coming in at No. 92

Despite ranking 21st on last January’s Baseball America top 100 list, outfielder Austin Hays was left off after an injury-plagued season that limited him to just 327 plate appearances. The 23-year-old batted only .242 with 12 home runs and a .703 OPS in 288 plate appearances at Bowie before undergoing ankle surgery in September.

Catcher Chance Sisco was on Baseball America’s list in each of the previous two years before a frustrating 2018 campaign in which he bounced between the Orioles and Triple-A Norfolk. Questions have persisted about his defense behind the plate, but Sisco, 23, also struggled mightily at the plate in 2018, batting just .181 with 66 strikeouts in 184 plate appearances for Baltimore and even posting an unimpressive .696 OPS in 151 plate appearances with Norfolk.
