Pittsburgh Pirates Prospects: Top Age-20 and Below Talents
By Noah Wright
Other Prospects To Know
These prospects aren't on many prospect lists, as the ones we went in-depth with were on FanGraphs or MLB Pipeline's Pirates' top prospect lists. However, the Pirates have plenty of other young prospects that fans should know about, starting with Andres Silvera.
Silvera pitched 41 innings for the Pirate DSL team, working to a 1.54 ERA, 2.13 FIP, and 0.89 WHIP. He struck out 29% of the opponents he faced with a walk rate of 3.9%. Even better was his 55.3% ground ball rate and not allowing a single home run. Silvera only works around 88-90 MPH, but given he won't turn 20 until July of 2024, there's still time for him to add size and strength to his 6'0", 188-LBS frame.
One of the team's highest-paid 2021-2022 international signees was Pitterson Rosa. In Rosa's first 22.1 innings, the right-hander allowed eight earned runs and walked 11 batters. However, he didn't let up a single home run and struck out 24. Rosa, like nearly all the players we've looked at, has a projectable frame, standing in at 6'2", 180 pounds. But Rosa is already topping out at 94 MPH, and is a converted outfielder, so he has some athleticism to go with the projection.
Inmer Lobo is a 19-year-old left-hander the Pirates acquired this past off-season from the Boston Red Sox in exchange for utility man Hoy Park. Lobo pitched 22 innings for the Sox DSL affiliate, allowing just two earned runs on two walks, 15 hits (just a single home run), and striking out 28. Lobo, like Silvera, only sits around the upper-80s/low-90s. His season was cut short by an injury, but he will be interesting to watch at the FCL next season.
Miguel Sosa is yet another catching prospect to keep an eye on at the FCL. In 109 plate appearances, Sosa batted .305/.468/.512 with a 166 wRC+. Sosa walked more than twice as often as he struck out (25:12 BB:K ratio), and 11 of his 25 hits went for extra bases (eight doubles, three home runs). Sosa split his time between the backstop and left field at the DSL last season. He has some athleticism and a strong arm, along with decent raw pop.
Jesus Castillo was the batting champion at the FCL, slashing .352/.439/.383 through 150 plate appearances. Castillo struck out just 18 times and drew 17 walks. But his power amounted to just four doubles and an ISO below .050 at .031. Castillo, a middle infielder, is a stout 5'9", 145 pounds. He makes a lot of contact but is held back by his lack of power.
