DETROIT\u00a0\u2014 The Houston Astros<\/a> are calling up right-handed pitching prospect Miguel Ullola<\/a> from Triple-A to their major-league roster, a person with knowledge of the move confirmed Saturday.<\/p>\n

Ullola, 24, projects to join the Astros\u2019 bullpen ahead of Sunday\u2019s series finale against the Tigers and will be seeking his major-league debut. His impending call-up was first reported by The Athletic<\/a>.<\/p>\n

Ullola is already on the Astros\u2019 40-man roster, added last offseason to protect him from the Rule 5 draft<\/a>. Baseball America and MLB Pipeline both ranked Ullola as the No. 11 overall prospect in the Astros\u2019 system entering this season.<\/p>\n

Signed in 2021 from the Dominican Republic, Ullola rose through the minors as a starter but moved into a relief role last month at Triple-A Sugar Land.<\/p>\n

In the minors, Ullola has paired nasty stuff with command issues. He has held opponents to a .190 batting average and struck out 12 hitters per nine innings across parts of six minor-league seasons. He has also walked 6.2 batters per nine over 478 \u2154 minor-league innings.<\/p>\n

That profile helped spur his recent shift to the bullpen at Triple-A, exploring if shorter outings could help Ullola operate in the zone more. Ullola posted a 2.70 ERA with six walks and 16 strikeouts in his first 10 relief appearances for Sugar Land.<\/p>\n

Just one of those appearances comprised more than an inning. Still, Ullola would provide reinforcement for an Astros bullpen that has been used heavily in the last week while operating short-handed.<\/p>\n

The Astros have carried a six-man rotation during a stretch of 13 games with no off day. That ends next Wednesday, perhaps offering the flexibility to bring up an additional reliever.<\/p>\n

The Astros did not confirm Ullola\u2019s call-up or announce a corresponding move Saturday.\u00a0Teng could be a part of a corresponding move, however, given that he has minor-league options and is already seeing an increased workload over recent seasons.<\/p>\n

Teng began the season in Houston\u2019s bullpen and moved into the rotation in mid-May. He has thrown 64 innings at the major-league level, posting a 4.36 ERA. Teng totaled 86 \u2154 innings in 2025 between Triple-A and the majors with the San Francisco Giants, and 90 innings between those levels in 2024.<\/p>\n

After his start Saturday, in which he allowed five runs, Teng said through an interpreter that \u201ccompared to the start of the season, I would say there\u2019s definitely some fatigue and tiredness,\u201d and noted that his inning count is nearing those of the past two seasons. Teng added the fatigue is \u201cstill manageable.\u201d<\/p>\n

Houston used relievers to cover 27 \u2154 innings across a six-game span through Saturday (including one inning from center fielder Jake Meyers in a blowout loss). It appears Ullola will now help fortify the group.<\/p>\n","protected":false},"excerpt":{"rendered":"DETROIT\u00a0\u2014 The Houston Astros are calling up right-handed pitching prospect Miguel Ullola from Triple-A to their major-league roster,…\n","protected":false},"author":2,"featured_media":353055,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[7],"tags":[56,58,57],"class_list":["post-353054","post","type-post","status-publish","format-standard","has-post-thumbnail","category-houston","tag-houston","tag-houston-headlines","tag-houston-news"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/us-tx\/wp-json\/wp\/v2\/posts\/353054","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/us-tx\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/us-tx\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-tx\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-tx\/wp-json\/wp\/v2\/comments?post=353054"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/us-tx\/wp-json\/wp\/v2\/posts\/353054\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-tx\/wp-json\/wp\/v2\/media\/353055"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/us-tx\/wp-json\/wp\/v2\/media?parent=353054"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-tx\/wp-json\/wp\/v2\/categories?post=353054"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-tx\/wp-json\/wp\/v2\/tags?post=353054"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
