A’s trade All-Star catcher Derek Norris to the Padres

The revamping Oakland Athletics made yet another trade of a star player this off-season, sending catcher Derek Norris and minor league right-hander Seth Streich to the San Diego Padres on Thursday night for righties Jesse Hahn and R.J. Alvarez along with an international signing bonus slot.

San Diego’s been busy, too. At about the same time they wrapped up the deal with the A’s, the Padres finalized a trade to acquire outfielder Matt Kemp from the division rival Los Angeles Dodgers.

Norris, a 25-year-old All-Star, batted .270 with 10 home runs and 55 RBIs in 127 games for the A’s, who lost 9-8 in the wild-card game at Kansas City. Oakland had depth at catcher, with capable backstops John Jaso and Stephen Vogt still on the roster despite both dealing with injuries last season. Jaso ended the year with a concussion for the second consecutive season.

A’s General Manager Billy Beane made his second trade of the day, while San Diego has several pending swaps. On Wednesday, the Padres acquired outfielder Wil Myers from Tampa Bay. San Diego sends catcher Yasmani Grandal and two pitchers to the Dodgers in the deal for Kemp and catcher Tim Federowicz.

The New York Daily News first reported Norris was headed to the Padres.

Alvarez, 23, was 0-0 with a 1.13 ERA in 10 appearances for the Padres last season.

Earlier Thursday, the A’s acquired left-hander Eury De La Rosa from the Arizona Diamondbacks for cash.

The 25-year-old Hahn went 7-4 with a 3.07 ERA in 14 outings and 12 starts over 73 1/3 innings while spending the final four months in the big leagues.

Hahn, who’s 6-foot-5 and made his major league debut on June 3, could fit into an Oakland rotation that lost both Jon Lester and Jason Hammel in free agency to the Chicago Cubs while Oakland traded Jeff Samardzija to the White Sox.

Of Oakland’s seven All-Stars last season, only two are left — reliever Sean Doolittle and starter Scott Kazmir.

Royals agree to two-year deal with Medlen

Former Atlanta right-hander Kris Medlen has agreed to an $8.5 million, two-year contract with the Kansas City Royals after missing last season while he recovered from Tommy John surgery.

Medlen will make $2 million next year and $5.5 million in 2016 under the agreement announced Thursday and could earn up to $10 million in performance bonuses based on starts and innings. The deal includes a 2017 option with a $1 million buyout.

The 29-year-old went 14-12 with a 3.11 ERA in 2013, his only full season as a starter, and went 4-0 with a 1.00 ERA in his last five starts. Medlen, who hurt his elbow in spring training, also missed most of the 2011 season while he was rehabbing from Tommy John surgery.

The St. Petersburg City Council rejected a deal between the Rays and the city’s mayor that would have allowed the team to search for new stadium sites on both sides of Tampa Bay. The council voted 5-3 Thursday to reject a proposed agreement reached this month by Mayor Rick Kriseman. The team has played since its inception in Pinellas County at what now is called Tropicana Field. The agreement would have allowed the Rays to evaluate sites on the east side of the bay in Hillsborough County, where Tampa is located. ...
