Jeremy Pena

Allen was the starting shortstop for Atlanta in 2025, and while he posted just a .535 OPS in that season, he was one of the best defenders up the middle. The 27-year-old could be the starting second baseman for Houston in 2026, and he along with Jeremy Pena would be as good of double-play combination -- defensively -- as there is. It helps the Astros' defense, but there's zero fantasy value in Allen's game.
