SEATTLE -- The Mariners finally landed the established shortstop theyve long been trying to find.To do it, they had to part with a talented young pitcher who still has the potential to blossom.Seattle and Arizona pulled off a five-player trade on Wednesday night, with the Mariners acquiring speedy infielder Jean Segura?and the?Diamondbacks?getting right-hander Taijuan Walker as the centerpieces of the deal.Segura immediately projects as Seattles leadoff hitter and starting shortstop, solidifying an infield that already includes Kyle Seager at third base and Robinson Cano at second. Segura hit .319 with 20 home runs and 63 RBIs last season for the Diamondbacks, led the National League with 203 hits and posted a career-high 5.7 WAR.Segura was one of the premier offensive players in the majors last season, Mariners general manager 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.But getting Segura meant the Mariners had to give up on the inconsistent Walker, a power arm who has showed occasional flashes of brilliance.Its always hard. Its hard any time you give up talent like Taijuan, Dipoto said. Frankly, you have to give to get ... and Segura fit this club.Arizona also obtained shortstop Ketel Marte, while Seattle received outfielder Mitch Haniger and left-hander Zac Curtis.The addition of Walker could help a dreadful Arizona pitching staff that posted a 5.09 ERA last season, tied with Minnesota for worst in the majors. He joins a rotation that includes ace Zack Greinke, Shelby Miller, Patrick Corbin and Archie Bradley.The Diamondbacks finished 69-93 last season, fourth in the NL West.A touted prospect, the 24-year-old Walker went 8-11 with a 4.22 ERA and 119 strikeouts in 25 starts for Seattle last season. He would be outstanding one game and then struggle the next.Young, controllable pitching is hard to find, and adding Taijuan to the rotation gives us significant depth in that area, new Arizona general manager Mike Hazen said.In Ketel, we believe we have acquired a talented, switch-hitting shortstop to join a very solid core of young middle infielders.Segura is also an immediate upgrade at shortstop for Seattle, which went 86-76 last season and finished three games out of a playoff spot.This trade made more sense for where our roster is, and Jean Segura fit this club about as well as any player we were looking at, Dipoto said.Information from The Associated Press was used in this report.

KANSAS CITY, Mo. -- Salvador Perez picked a perfect time for his first pickoff of the season.The star catcher homered, then helped protect the lead by trapping Kyle Seager off first base in the eighth inning to lead the Kansas City Royals over the Seattle Mariners 5-3 Saturday.Perez hit a solo home run off the foul pole in the seventh that gave the Royals a two-run lead. Moments later, the World Series MVP made the defensive play of the game.With runners at the corners and one out, Perez threw down to first baseman Eric Hosmer for his 18th career pickoff.That was Hosmer, Perez said He gives me a sign and I throw the ball right to him. I think he knows more than me.In turn, Hosmer credited the catcher.Thats all him, Hosmer said. Just knowing hes behind the plate youve got to stay close to the bag at all times because hes so quick back there.The pitch takes him that way and he just throws it right back over there, just an unbelievable play and thats why Salvys the best. He changes the game, just completely took all the momentum away from them right there. First and third with one of their big hitters up, it was a huge play.Even Seager had to compliment Perez.You cant get picked off in that situation, but hes pretty special back there. But, I obviously got off too far.Edinson Volquez (8-8) gave up three runs and six hits in six innings.Kelvin Herrera pitched a perfect ninth for his first save since April 10, 2013.Wade Miley (6-6) gave up 10 hits. He left affter Cheslor Cuthberts RBI single made it 4-3 in the sixth.dddddddddddd.Cuthbert also doubled and finished with two RBI.Seager hit his 18th homer, tying it at 3 in the fourth. Nelson Cruz added two hits for Seattle.TRAINERS ROOMRoyals: LHP Jason Vargas threw a simulated game and manager Ned Yost was encouraged by the progress he showed. Looked good, really good, he said. Three pitches, good changeup, fastball with life. Good breaking ball, good first step. Yost anticipates Vargas could make a return in September.ROSTER MOVEThe Cleveland Indians claimed LHP Tyler Olson off waivers from the Royals and will be sent to Triple-A Columbus. Olson was designated for assignment by the Royals on July 5.UP NEXTIn Sundays finale, former Royals draftee LHP Mike Montgomery (2-3) will get the start for the Mariners against RHP Dillion Gee (3-2). Montgomery was selected in the first round in 2008 and was part of the December 2012 trade with Tampa Bay that brought pitchers Wade Davis and James Shields to Kansas City. Probably cool for Mike, Mariners manager Scott Servais said. I know he was drafted by the Royals, was a high prospect there. The anxiety of going back and pitching against your friends, your teammates, your former teammates, but hes been away long enough now, I hope that its kind of gone away and Im sure hell give us a good effort.
