Miguel Ullola Wild, But Effective in First Half
Houston Astros pitching prospect Miguel Ullola owns the second-highest walk rate in Triple-A at 15.8 percent, but has limited damage otherwise and holds a 3.80 ERA in 64 innings as we head into the second half. Ullola's command ails him fairly often, as he has allowed four or more walks in five of his 16 starts this season. He has great stuff, which has led to a strong 27.4 percent strikeout rate, but the walk rate is untenable. In addition, he doesn't combat the free passes with a high ground ball rate at just 36.3 percent. The right-hander has previously shown better ground ball rates at other levels of the minor leagues, and that could be a key piece for him. He likely projects as a reliever in the major leagues and could develop into a solid one with Houston's track record.
