Fernando Rodriguez RP OAK 2 Days

Rodriguez was designated for assignment Thursday, ESPN.com reports.

With the Athletics needing to clear two more spots on their 40-man roster following a flurry of trading activity, Rodriguez became a necessary casualty. There's a good chance another team might be interested in scooping him up, however, after he turned in an ERA under 2.00 to go along with a 53:16 K:BB ratio over 45.2 innings at the Triple-A level last season.

Matt Kemp OF SD 2 Days

The deal between the Dodgers and Padres involving Kemp will go through as originally reported, ESPNLosAngeles.com reports.

The Padres were said be wavering after Kemp's physical revealed "severe" arthritis in his hips, but the Dodgers reportedly never felt the deal was seriously in jeopardy. It seemed possible the two sides would have to rework the trade, but it ends up being exactly as was first reported; Kemp, catcher Tim Federowicz and $32 million to the Padres for Yasmani Grandal, Joe Wieland and Zach Eflin. Eflin was then flipped to the Phillies, along with Tom Windle, in exchange for Jimmy Rollins.

R. J. Alvarez RP OAK 2 Days

The Padres traded Alvarez, along with Jesse Hahn, to the A's on Thursday for Derek Norris, Seth Streich and an international signing slot, Jeff Passan of Yahoo! Sports reports.

Part of the package that brought closer Huston Street to Anaheim in July, Alvarez posted a minuscule 1.25 ERA, 0.96 WHIP and 61:13 K:BB in 38 appearances at the Double-A level last season. He wasn't as sharp with his control in a September audition with the Padres, but Alvarez can easily miss bats with his mid-90s fastball, sharp slider and changeup. It should only be a matter of time before he carves out a back-end bullpen role with Oakland.

Jesse Hahn SP OAK 2 Days

The Padres traded Hahn along with R.J. Alvarez to the A's on Thursday for Derek Norris, Seth Streich and an international signing slot, Jeff Passan of Yahoo! Sports reports.

Hahn enjoyed a great deal of success in his first stint in the majors last season, posting a 3.07 ERA, 1.21 WHIP and 70:32 K:BB in 14 appearances (12 starts) spanning 73.1 innings. The right-hander relies heavily on his outstanding 12-6 curveball to complement a low-90s fastball, while using his slider and changeup sparingly. With just two truly reliable offerings (at the moment), it's possible Hahn could ultimately end up in a late-inning role with Oakland, though the A's figure to keep him stretched out early on.

Derek Norris C/DH SD 2 Days

Norris was traded to the Athletics on Thursday, Mark Feinsand of New York Daily News reports.

The exact terms of Norris' trade are unclear at this point, but he is obviously the biggest piece of the deal. He will now move into a lineup for the Padres that is coming together with the additions of Wil Myers and Matt Kemp. Norris will likely take the starting catching duties for the Padres, with the veteran Ryan Hanigan now being relegated to a backup role.

Audry Perez C COL 2 Days

Perez signed a minor league contract with the Rockies and is expected to be invited to major league spring training, MLB.com reports.

Perez, who turns 26 next week, hit .292 in 62 games with the Cardinals' Triple-A Memphis affiliate last season, but drew just four walks in 248 plate appearances and has posted a double-digit home run total just once in seven minor league seasons. While he'll get to attend spring training with the big club, it will likely take an injury or trade for him to get an opportunity in the backup role.

Johnny Giavotella 2B KC 2 Days

Giavotella has been designated for assignment to make room for Kris Medlen.

Giavotella could be called up sometime next season in the event of an Omar Infante or Mike Moustakas injury if he stays with the Royals, but he's essentially a Quadruple-A player at this point. A team desperate for infield depth could pick him up.

Kris Medlen SP KC 2 Days

Medlen (elbow) signed a two-year contract with the Royals on Thursday that includes a mutual option for 2017.

The Braves were pushing to re-sign Medlen to a two-year deal after declining to tender him a contract earlier this month, but a former Braves executive, current Royals GM Dayton Moore, swooped in and signed the right-hander away from Atlanta. Medlen underwent his second Tommy John surgery in March and missed the entire 2014 season as a result, but he went 15-12 with a 3.11 ERA and 1.22 WHIP in his first full season as a starter in 2013. It's uncertain when Medlen will be ready to return, but he could wind up playing a significant role in the Royals' rotation during the second half of the season.

George Kottaras C CWS 2 Days

Kottaras agreed to a minor league deal with the White Sox on Thursday, Chris Cotillo of SB Nation reports.

The 31-year-old will presumably be invited to attend major league camp for spring training, with a chance to compete for the backup job behind Tyler Flowers. Kottaras played for three different teams last season (Indians, Cardinals, Blue Jays), slashing a combined .233/.351/.533 with three homers and five RBI in 18 games. He's just a .215/.326/.411 career hitter at the major league level.

Carlos Rivero 3B SEA 2 Days

Rivero has signed a minor league contract with the Mariners that includes an invite to spring training.

The Mariners opted not to tender Rivero a contract earlier this month but brought him back on a minor league deal. A waiver acquisition in November, Rivero spent the 2014 campaign in the Red Sox system, splitting the year between Double-A and Triple-A. He had decent numbers with Triple-A Pawtucket (.286/.341/.407) and is a versatile defender, so there's an outside chance he could push for a utility role.
