Minor MLB Transactions: 8/6/16

Here are today’s minor moves from around the league.

• The Brewers have announced the release of right-hander Ariel Pena, who was the last remaining piece in the organization from its 2012 trade with the Angels that sent Zack Greinke to Los Angeles. Milwaukee also received infielder Jean Segura and righty Johnny Hellweg in that deal. Pena threw 29 innings with the Brewers and logged a 5.59 ERA, 8.38 K/9 and 4.97 BB/9. The 27-year-old has struggled mightily at the Triple-A level in 2016, having recorded an 8.36 ERA and 7.65 BB/9 in 37 2/3 frames.
• The Braves announced last night that they would selected the contract of righty Roberto Hernandez, who will start tonight against the Cardinals. (They cleared a roster space earlier today when they shipped reliever Hunter Cervenka to the Marlins.) The pitcher formerly known as Fausto Carmona has pitched for two Triple-A teams this year, combining for a 4.60 ERA, 6.2 K/9 and 2.7 BB/9. He hasn’t yet appeared in the big leagues in 2016, but he appeared in all of the previous ten seasons, pitching to a career 4.58 ERA, 5.5 K/9, 3.4 BB/9 and 56.5% ground ball rate.
• The Pirates are expected to select the contract of Curtis Partch, MLB.com’s Adam Berry notes (Twitter links). Partch will take the roster spot of fellow hard-throwing righty Arquimedes Caminero, who was traded to the Mariners today. It’s possible Partch’s stay in the big leagues could be short, however, since the team intends to move starter Jeff Locke to the bullpen and will require an extra starter later this week. Partch has a 2.05 ERA, 9.9 K/9 and 3.9 BB/9 for Triple-A Indianapolis this season. He also made one appearance with the Pirates, allowing three runs without retiring a batter.
• The Red Sox have requested release waivers on lefty Tommy Layne, Jason Mastrodonato of the Boston Herald tweets. Boston designated Layne for assignment this week to make room for Fernando Abad after Layne posted a 3.77 ERA, 7.9 K/9 and 4.4 BB/9 in 28 2/3 innings while struggling against lefties.
