Philadelphia Phillies
The Phillies signed two former big leaguers to minor league deals; J.P. Arencibia, and Ernesto Frieri. According to Jon Morosi, both players will "receive invites to major-league spring training", but it's unclear what their chances of making the team are.
While Arencibia and Frieri both had time at the major league level in 2015, neither one had a prolonged stay. Arencibia played in 24 games for the Rays, posting a slash line of .310/.315/.606 with a wOBA of .388, and a wRC+ of 152; however his statistics were likely inflated by an unsustainable .364 BABIP.
Frieri threw 23.1 innings, also with the Rays, and posted a K/9 of 7.33, a BB/9 of 4.24, and a HR/9 of 2.31. His ERA and FIP were 4.63, and 6.39, respectively.
Washington Nationals
The Nationals signed Nick Masset, who's played for the Rangers, White Sox, Reds, Rockies, Marlins, and Braves, to a minor league deal with an invite to spring training. In 25 innings in 2015, he posted a K/9 of 6.48, a BB/9 of 3.24, and a HR/9 of 1.08. His ERA and FIP were nearly identical, 4.68, and 4.57, respectively, and Masset produced an fWAR of -0.3.
Kansas City Royals
The Royals agreed to terms with Dillon Gee earlier today, who they've apparently been interested in for some time.
Dillon Gee turned down major league offers from rebuilding teams to be with the Royals. Good match, too, considering their fielding.

While he was once a mainstay in the Mets' rotation, Gee only made seven starts for New York in 2015. In 39.2 innings, he posted a K/9 of 5.67, a BB/9 of 2.50, and a HR/9 of 1.13. His ERA was an ugly 5.90, and while his FIP wasn't pretty either, it was a noticeably better 4.42.
Atlanta Braves
After 26.2 innings with the Diamondbacks in 2015, Jhoulys Chacin will be heading off to the Braves. Last season he posted a K/9 of 7.09, a BB/9 of 3.38, and HR/9 of 1.35. His ERA was 3.38, while his FIP was 4.63. In his career, Chacin has made 113 starts, and owns an ERA of 3.76, and an FIP of 4.05. With Atlanta's current rotation it's possible that Chacin could find his way onto the big league club as depth or as an emergency starter.
Chicago White Sox
The White Sox agreed to a deal with former Giants' backup catcher, Hector Sanchez. Due to various injuries, and being lower on the depth chart than Andrew Susac, Sanchez only played in 28 games in 2015. He's never been an above average major league hitter, but he's a more than capable defensive catcher. Sanchez's biggest problem throughout his career has been concussions, as he's been terribly unlucky behind the plate with foul tips.
Chicago Cubs
Another former Giant has agreed to a deal with a Chicago team, as Jean Machi will be a member of the Cubs' organization at the outset of 2016. In 58 innings during 2015 between the Giants and Red Sox, Machi posted a 5.12 ERA, along with a 4.67 FIP. However from 2013-2014, he owned an ERA of 2.49, and an FIP of 2.93. If the Cubs can figure out what plagued him in 2015, Machi could prove to be an extremely effective reliever again.
Milwaukee Brewers
The Brewers added Alex Presley, Jake Elmore, and Daniel Tillman on minor league deals, all with invites to major league spring training. Presley is an outfielder with a below league average bat, and is likely nothing more than organizational depth. In 1105 career big league plate appearances, he has a slash line of .259/.299/.393 with a wRC+ of 91. Elmore is a utility player, as he spent time at 1B, 2B, 3B, SS, and LF during the 2015 season.
Tillman is perhaps the most interesting of the three, as he posses strikeout stuff, and had success during the 2015 season between High-A and AA.
Baltimore Orioles
After 8 plate appearances with the Angels in 2015, outfielder Alfredo Marte will head to the Orioles. He spent seven seasons in the Diamondbacks' organization before heading to Anaheim. He has just 170 big league plate appearances, and owns a slash line of .181/.249/.284 with a wOBA of .243 and a wRC+ of 46.
