The Astros have designated outfielder Preston Tucker for assignment, per a club announcement. His roster spot will go to just-signed reliever Hector Rondon.
Tucker, a seventh-round pick in the 2012 draft, has generally posted strong numbers during his rise through the Houston system. He reached the majors in 2015, hitting for enough power (including 13 home runs in 323 plate appearances) to produce at just over the league-average rate despite carrying only a .297 on-base percentage. But Tucker struggled badly in the following season and has not been back to the big leagues since.
In 2017, playing exclusively at Triple-A, Tucker posted a .250/.333/.465 batting line with 24 home runs over 569 plate appearances. On the promising side, he boosted his walk rate to a career-best 11.4% and struck out just 17.9% of the time. But his overall output was not much better than the mean in the hitter-friendly PCL. Tucker’s .263 batting average on balls in play no doubt had an impact, though he has typically generated a low BABIP.
All told, it seems reasonable to expect that another organization will be glad to risk a 40-man spot on Tucker, who has one more option year remaining. His younger brother, Kyle Tucker, remains in the Astros system and is considered one of the team’s top prospects.
