The Padres have returned Rule 5 pick Jandel Gustave to the Astros, Houston announced. Gustave will open the year in Double-A.

The right-hander was originally a Rule 5 selection of the Red Sox, but had his rights dealt to the Royals. He was then claimed off waivers by San Diego. Today’s move will bring his travels to an end, at least for the time being.

Gustave, a raw 22-year-old with a huge fastball, was never really expected to stick with the Padres. Though he has shown the ability to rack up strikeouts at a useful pace in the low minors, Gustave has yet to prove he can keep the ball in the zone — let alone that he can consistently retire major league hitters.
