Over the next few weeks I will be looking at the top performers at each level in the Astros system. This week is the Dominican Summer League Astros.
Kevin Alvarez, OF
Alvarez was the Astros prize international signing as he inked a deal worth $2 million in January of this year. The outfielder lived up to those expectations as his name was all over the leader board. In 47 games, the 17-year-old hit .300 with 12 doubles, 3 triples, 2 home runs, 33 runs batted in and 11 stolen bases. This also included an impressive 12.0% walk rate and insane 9.9% strikeout rate. Really strong season at 17 years old. He was also named as a DSL All-Star.
Adrian Ardines, RHP
Ardines absolutely dominated in 2025. The 18-year-old was signed in January of 2024 and after a rough debut in 2024, he posted a 1.91 ERA over 42.1 innings in 2025. This included a team leading 56 strikeouts while walking just 7 batters, good for a ridicules 8 K/BB rate and 30.1 K/BB%. He should be stateside in 2026.
Anderson Arienamo, INF
Arienamo was signed by the Astros in January of 2025 and his first taste of professional baseball went really well. The infielder played in 51 games for DSL Orange and led the team in doubles, home runs, batting average and on-base plus slugging. The 18-year-old showed off some pop with the 10 doubles and 5 home runs, while still hitting .300. He also had a .413 OBP with 18 stolen bases. Arienamo was named a DSL All-Star as well.
Sami Manzueta, INF
Manzueta was the youngest position player on Astros Blue in 2025 playing most of the season at 16 years old. He posted some strong numbers though as he led the team in home runs (5) and had a .797 OPS over 46 games. He also impressed with the plate discipline as he walked 42 times to just 36 strikeouts. Strong first showing for the young infielder.
