We'll keep track of today's minor moves here.
- The Reds acquired infielder/outfielder Mark Teahen from the Diamondbacks for cash or a player to be named later, according to the D'Backs. Teahen, 31, was hitting .209/.321/.254 in 81 Triple-A plate appearances after struggling offensively in the Washington organization at that level last year. He was drafted in the first round by the A's in 2002 and spent five seasons with the Royals, hitting 18 home runs in '06.
- The Dodgers have signed pitcher Aaron Laffey to a minor-league deal, Chris Cotillo of CLNS Radio reports. MLBTR's Tim Dierkes has confirmed the signing. Laffey has been designated for assignment by the Mets and Blue Jays so far this season, and he elected free agency yesterday instead of accepting an outright assignment from the Jays. Laffey has appeared in five big-league games so far this year.
- Rangers minor-leaguer Randy Wells has retired, FOX Sports Southwest's Anthony Andro reports (on Twitter). Wells, 30, finished sixth in NL Rookie of the Year balloting in 2009, when he was with the Cubs. He appeared in 98 big-league games, mostly with Chicago, posting a 4.08 ERA, 5.9 K/9 and 3.1 BB/9. He made five starts in 2013 for the Rangers' Triple-A affiliate in Round Rock.
- The Mariners have signed outfielder Corey Patterson to a minor-league deal, MLB.com's Greg Johns reports (on Twitter). Patterson will report to extended spring training. Patterson, 33, hit .251/.285/.410 for the Brewers' Triple-A team in Nashville in 2012. He has played for the Cubs, Orioles, Reds, Nationals, Brewers, Blue Jays and Cardinals.
