Minor Moves: Marlins, Red Sox, Mortensen, Mock

Here are today's minor moves from around the league…

• The Marlins announced (via Twitter) the transfer of Marcell Ozuna to the 60-day disabled list.  This frees up a roster spot for Gil Velazquez, called up from Triple-A to take the place of Placido Polanco, who is going on the seven-day DL for concussion issues.
• The Red Sox announced that they have moved Clay Buchholz and Andrew Bailey to the 60-day DL and sent Rubby De La Rosa, Ryan Lavarnway and Brock Holt to Triple-A in order to create roster spots for David Ross (activated from the 60-day DL) and call-ups Xander Bogaerts and Brayan Villarreal.  Bailey is out for the season but Buchholz may soon return from a neck/shoulder issue that has kept him sidelined since June.  Steve Adams examined the Bogaerts promotion earlier today on MLBTR.
• The Rays signed right-hander Jared Mortensen to a minor league contract and assigned him to High-A Charlotte last week, according to a release from the American Association of Independent Professional Baseball. Mortensen, 25, went undrafted out of LSU-Shreveport and had been pitching for the American Association's Grand Prairie AirHogs. In 100 1/3 innings for the AirHogs (15 starts), he posted a 3.77 ERA with 8.4 K/9 and 2.2 BB/9. Mortensen has made one relief appearance since reporting to the Florida State League, firing a pair of scoreless innings.
• The Diamondbacks released right-hander Garrett Mock from Triple-A Reno, according to the Pacific Coast League Transactions page. The 30-year-old Mock posted a 6.72 ERA with 6.5 K/9 and 4.6 BB/9 in 75 innings for the Aces this season. Mock spent parts of three seasons with the Nationals from 2008-10, posting a 5.17 ERA in 135 2/3 innings, but he hasn't pitched in the big leagues since. The D-Backs are his third organization since the Nationals, as he's also spent time with the Astros and Red Sox.
• Following the releases of Luis Cruz and Elliot Johnson earlier today, Sean O'Sullivan is the only player in DFA limbo at this time.  O'Sullivan was designated for assignment by the Padres earlier today.
