Minor Moves: Martinez, Spence, Shirek, Blue Jays

The latest minor moves from around MLB…

• The Brewers have agreed to a $50K contract with Dominican outfielder Geraldy Martinez, according to the Dominican Prospect League.  Martinez, 17, hits from the right side of the plate and "hits the ball hard gap to gap with true power from [his] pull side," according to the DPL website.
• The Yankees announced that they have outrighted left-hander Josh Spence to Triple-A after Spence cleared waivers.  Spence was claimed off waivers from San Diego earlier this month and designated for assignment by New York earlier this week to create 40-man roster space for Kevin Youkilis.
• The White Sox announced that they have requested unconditional release waivers on Charlie Shirek so that the right-hander can pursue opportunities in Asia. The 27-year-old spent this past season at Triple-A Charlotte, where he posted a 3.65 ERA with 6.2 K/9 and 1.5 BB/9 in 170 1/3 innings as a starter. Shirek, who does not have any MLB experience, will pitch in Korea, MLB.com’s Scott Merkin reports (on Twitter). Chicago’s 40-man roster now has 38 players.
• The Blue Jays announced that they signed right-hander Ramon Ortiz and outfielder Ryan Langerhans to minor league deals that include invitations to MLB Spring Training. The 39-year-old Ortiz spent the 2012 season with the Yankees' Triple-A affiliate, posting a 3.45 ERA in 27 starts. Langerhans, 32, spent most of this past season with the Angels' Triple-A affiliate, but he did appear in two games at the MLB level. He posted a .250/.369/.446 batting line in 401 Triple-A plate appearances.
• The Blue Jays also signed minor league infielder Lance Zawadzki to a minor-league deal, Shi Davidi of Sportsnet.ca reports (on Twitter).
