The Seattle Mariners have acquired Jean Segura from the Arizona Diamondbacks in exchange for Taijuan Walker.

Seattle also received outfielder Mitch Haniger and left-hander Zac Curtis, while Arizona landed shortstop Ketel Marte.

"Segura was one of the premier offensive players in the majors last season," Jerry Dipoto said. "His combination of average, power and speed is extremely difficult to find, especially at a position like shortstop and at the top of our lineup.

"We believe pairing him with Robinson Cano gives us tremendous offensive potential in the middle of our infield."

The New York Yankees released utilityman Dustin Ackley on Friday and announced that injured pitcher Nathan Eovaldi was designated for assignment.

New York also traded left-hander James Pazos to the Seattle Mariners for minor league right-hander Zack Littell.

The New York Yankees have traded Brian McCann to the Houston Astros for prospects Albert Abreu and Jorge Guzman.

Houston is expected to have McCann and Evan Gattis split duties at catcher.

New York will reportedly send some cash to the Astros along with McCann.

Mariners GM Jerry Dipoto added a potent right-handed hitter who can team with first baseman Daniel Vogelbach or play a corner-outfield spot, acquiring Danny Valencia from the A's on Saturday for Minor League pitcher Paul Blackburn.

"I'm excited about it," Valencia said. "It seems like Oakland is going through a rebuild. Seattle is on the verge of the playoffs, so that's what really caught my attention, to be able to play in the postseason. That's the most important goal, and I'm looking forward to taking part in that."

Valencia, 32, posted a .287/.346/.446 line with 17 home runs and 51 RBIs in 471 at-bats for Oakland last year, including .318/.389/.535 in 129 at-bats against left-handers.

The Seattle Mariners added depth to their catching corps on Sunday, acquiring catcher Carlos Ruiz in a trade with the Los Angeles Dodgers, a source told ESPN's Jayson Stark.

The Los Angeles Angels have acquired Cameron Maybin from the Detroit Tigers in exchange for right-hander Victor Alcantara.

The Angels, who plan to play Maybin in left field, also announced that they will exercise Maybin's $9 million contract option for 2017.

Cameron has spent his entire career as a center fielder.

He hit a career-best .315 with four homers, 43 RBIs and 15 stolen bases in 94 games for the Tigers last season.

"Being on this team, with the way they play baseball and constantly have guys moving, whether it's hit-and-run or stealing bases or bunting, I think I fit in with this style of play really well," Maybin said. "I'm looking forward to playing for Mike Scioscia. I've enjoyed watching how he manages from afar. I look forward to being part of that poetry in motion."
