Minor MLB Transactions: 6/12/16

Here are today’s minor transactions from around baseball:

• The Cubs have announced the signing of free agent infielder Josh Silver to a minor league pact. The 26-year-old has been playing for River City of the independent Frontier League since last season and has hit .320/.392/.442 with six homers in 306 PAs.
• The Diamondbacks have signed free agent third baseman Travis Denker to a minor league deal, per a club announcement. Denker last spent time with a major league organization in 2012, when he appeared in 64 games with the Dodgers’ Double-A affiliate. His only big league action came in 2008 as a member of the Giants, with whom he hit .243/.333/.486 in 42 plate appearances. Denker has bounced around multiple independent leagues and the Mexican League in recent years.
• The Cubs have claimed right-handed reliever R.J. Alvarez off waivers from the Athletics and optioned him to Triple-A Iowa, Carrie Muskat of MLB.com was among those to report (Twitter link). Alvarez has impressively struck out 32 hitters in 28 career major league innings, but the 2012 third-round pick has offset that by walking 18 and registering a 7.39 ERA. The 25-year-old is currently working his way back from March surgery on his right elbow.
• The Marlins have signed free agent righty Travis Ballew to a minor league contract, the team announced. The reliever spent 2012-15 with the Astros organization after going in the 23rd round of the draft, though Houston never promoted him to the big leagues. Ballew, 25, opened this season pitching for Fargo-Moorhead of the independent American Association. In 221 career minor league innings, Ballew has posted a 4.03 ERA, 9.5 K/9 and 4.0 BB/9.
