Minor MLB Transactions: 12/16/17

The latest minor moves from around baseball:

• The Rockies have signed utilityman Shawn O’Malley to a minor league contract with an invitation to big league camp, Bob Dutton of Baseball America reports on Twitter. The switch-hitting, 29-year-old O’Malley has collected 305 major league plate appearances since debuting in 2014, batting a combined .231/.315/.317 with the Angels and Mariners and playing all over the diamond (every outfield spot, second base, shortstop and third). An appendectomy and arthroscopic shoulder surgery helped keep O’Malley out of the majors last year and limit him to 120 PAs between Seattle’s Double-A and Triple-A affiliates.
• Utilityman Ronny Rodriguez announced on Instagram that he’s joining the Tigers on a minor league deal (h/t: Evan Woodbery of MLive.com). Rodriguez had spent his entire pro career with the division-rival Indians since signing out of the Dominican Republic in 2010. He never cracked the majors with the Tribe, though, instead topping out at Triple-A. The 25-year-old played at the minors’ highest level from 2016-17 and hit a respectable .274/.308/.427 in 971 PAs. Rodriguez has seen action at every position but pitcher, catcher and left field during his minor league career, as Woodbery notes.
• The Brewers announced the re-signing of 24-year-old right-hander Angel Ventura to a minors pact. Ventura, whom the Brewers signed out of the Dominican in 2011, owns a 3.96 ERA with 8.1 K/9 and 3.5 BB/9 across 534 minor league innings with the organization (130 appearances, 67 starts)
