The Astros released right-hander Fernando Nieve to allow him to sign with a Korean team, according to Zachary Levine of the Houston Chronicle (on Twitter). The Pirates signed Nieve in December and released him in March, when he didn't make the Opening Day roster. Two days later, Nieve signed with the Astros.
Nieve, 28, pitched 42 innings for the Mets in 2010, posting a 6.00 ERA with 8.1 K/9, 4.7 BB/9, 2.1 HR/9 and a 37% ground ball rate before he was Mets granted him free agency. No pitcher who completed 40 innings or more matched Nieve's 18.5% HR/FB rate last year.
The Venezuela native has started three games for the Astros' Triple-A affiliate this year, posting a 7.63 ERA with 10.0 K/9 and 2.9 BB/9 in 15 1/3 innings.
