1/6 UPDATE #2: Baseball America is reporting that the Cubs have signed 32-year old switch-hitting catcher Carlos Corporan to a 2017 minor league contract. He will almost certainly get an NRI to Spring Training.
Corporan has considerable MLB experience (232 games and 780 PA over the course of six seasons with MIL, HOU, and TEX), and he will battle Ali Solis (signed by the Cubs to a 2017 minor league contract last month) for the veteran catcher slot at AAA Iowa and for the Chicago Cubs unofficial #3 catcher gig (would be called up to Chicago if anything happens to Willson Contreras or Miguel Montero). Corporan has hit 218/280/342 over the course of his MLB career (4+019 MLB Service Time).
A native of Puerto Rico, Corporan was selected by the Milwaukee Brewers out of Lake City CC in the 12th round of the 2003 draft. He is a solid defensive catcher, but he struggled mightily at the plate in 2016 (hitting just 197/246/323 in 57 AAA games), first at Durham (TB) and then at New Orleans (MIA), getting released both times. However, Corporan is currently hitting a robust 321/379/425 for Carolina in Liga de Beisbol Profesional Roberto Clemente (the Puerto Rican winter league), and is 3rd in the PWL in hitting, 5th in OBP, and 6th in doubles.
1/6 UPDATE #1: Baseball America is reporting that the Cubs have signed 3B-1B Chris Dominguez to a 2017 minor league contract. I would think that he will probably get an NRI to Spring Training, and then will provide depth at AAA Iowa.
Now 30 years old, Dominguez was selected by the San Francisco in the 3rd round of the 2009 draft out of the U. of Louisville. He hit 21 HR and drove in 101 runs in his first full season (Lo-A Augusta) in 2010 and was ranked one of the Giants Top 10 prospects by Baseball America and was rated as having the organization's top infield arm going into the 2011 season, but he never reached his potential, spending the past five seasons in AAA with San Franicisco (2012-14), Cincinnati (2015), and Boston (2016).
Dominguez hit 241/275/439 at Pawtucket in 2016 with 13 HR in 77 games (298 PA), missing considerable time with an oblique strain. He has hit just .175 with two HR in two "cups of coffee" in the big leagues (eight games with the Giants in 2014, and 14 games with the Reds in 2015).
ORIGINAL POST (12/24): Baseball America is reporting that the Cubs have signed five more free-agents to 2017 minor league contracts.
All five will likely receive an NRI to Spring Training with the big club.
One of the players is a former Cubs minor leaguer, and the other four have varying degrees of big league experience with other MLB clubs.
