Another busy week down on the farm as the season continues to roll on. Here’s a look at some of the biggest developments across the system with this week’s Pipeline Report.
System Spotlight
Walker Janek – C – Corpus Christi
Janek was selected by the Astros in the first round of the 2024 MLB Draft out of Sam Houston State. He put together a solid first full season in 2025, batting .263 with 21 doubles, 12 home runs and 30 stolen bases at High-A Asheville. He opened the 2026 season with Corpus Christi but struggled out of the gate, hitting just .123 with one home run in April. In early May, he landed on the injured list and then suffered another setback during a rehab assignment in June.
After rehabbing with the FCL Astros, Janek returned to Corpus Christi in mid-July. While it’s still a small sample, he has looked like a completely different hitter. Over his last seven games, Janek is batting .480 with two doubles, four home runs, 10 RBIs and five stolen bases. Including his rehab games in the Florida Complex League, he is hitting .255 with an .839 OPS this season.
It’s an encouraging turnaround for one of the Astros’ top prospects and a reminder of the impact he can make when healthy.
Under-the-Radar Performer
Yamal Encarnacion – INF – Corpus Christi
Encarnacion has been in the Astros organization since signing as an international free agent in January 2021. He has steadily climbed the minor league ladder, posting solid numbers along the way, and earned an assignment to Double-A Corpus Christi to begin the 2026 season. At 22 years old, he’s putting together the best season of his professional career.
Overall, Encarnacion is hitting .261 with 18 doubles, three triples, five home runs and 44 stolen bases for the Hooks. He’s been especially hot of late, batting .404 over his last stretch while adding three doubles, two triples and four stolen bases. Even more impressive, he has already set career highs in doubles, home runs and stolen bases, and there’s still plenty of season left.
One Transaction This Week
Luis De Leon – C – Fayetteville
De Leon signed with the Astros in September 2024 for just $17,500, and he has already outperformed that bonus. After posting a respectable .784 OPS in 39 games as an 18-year-old in the Dominican Summer League last season, the Astros brought him stateside to begin 2026 with the FCL Astros.
He quickly became one of the club’s top hitters, batting .390 with eight doubles, four home runs, 23 RBIs and more walks than strikeouts over 38 games. Behind the plate, he also threw out 44% of attempted base stealers. According to his Instagram, De Leon was promoted to Fayetteville this week. At just 19 years old, he has an opportunity to climb the Astros’ prospect rankings in a hurry if he continues to perform at the next level.
Promotion Watch
Who Could Be Next?
I think Bryce Mayer has earned a promotion, and maybe not just to Triple-A. The Astros’ 16th-round pick in 2024 has been dominant for Corpus Christi, posting a 2.86 ERA with 91 strikeouts over 63 innings this season.
As impressive as those numbers are, he’s taken it to another level recently. Over his last five outings, the right-hander owns a 0.36 ERA with 32 strikeouts in 24.2 innings while allowing just 11 hits.
A promotion to Triple-A feels well deserved, but it wouldn’t surprise me if the Astros at least considered bypassing Sugar Land altogether should a need arise at the major league level.
