Minor MLB Transactions: 12/28/15

Matt Eddy of Baseball America has all the latest minor league moves, and there are some notable additions that have not yet appeared on the pages of MLBTR. Among them:

• The Marlins have signed righty Dylan Axelrod, lefty Troy Patton, and shortstop Robert Andino. Axelrod has seen MLB action in each of the last five seasons, but has seen his opportunities dwindle and owns only a 5.27 career ERA in 228 2/3 frames. Patton has had success at times in the bigs — he was a solid contributor to the Orioles from 2011-13 — and threw 30 1/3 innings of 2.37 ERA pitching last year at Triple-A. As for Andino, he’ll return to the organization with which he cracked the majors after spending last season in independent ball.
• Outfielder Alex Castellanos is heading to the Rockies, per Eddy. The 29-year-old has seen only minimal MLB time, despite solid numbers at Triple-A. He played briefly last year for Japan’s Yomiuri Giants.
• The Cardinals signed righty Jeremy Hefner, who is working his way back after Tommy John surgery. Hefner threw 224 1/3 frames for the Mets, with a 4.65 ERA, over 2012-13.
• Joining the Diamondbacks are righties Matt Buschmann and Jose Cisnero. Buschmann, 31, spent time with three organizations last year and has yet to crack the majors. Still just 26, Cisnero has made it to the bigs with the Astros but threw at Double-A last year in the Reds organization, continuing to show an ability to miss bats but also a predilection to miss the zone.
• The White Sox inked right-hander Josh Wall. Wall has made 15 major league appearances in past seasons. Heading into his age-29 campaign, the reliever will be looking for a chance to pick up some more MLB frames after throwing sixty innings of 2.70 ERA ball last year at Triple-A, with 10.4 K/9 against 3.2 BB/9.
