SEATTLE -- Things are changing so rapidly in the Mariners' world that Casper Wells, who started in left field on Sunday shortly after arriving in town, was joking with Erik Bedard before the game about how glad he was not to have to face the veteran left-hander's wicked curveball now that they were on the same team.
An hour later, Wells was among those bidding farewell as Bedard packed his bags and headed for Boston in Seattle's second trade in two days. General manager Jack Zduriencik went about stockpiling young talent with the addition of highly touted outfield prospects Trayvon Robinson and Chih-Hsien Chiang.
"It was like, 'Hi, bye,'" Wells said after going 1-for-4 in his Mariners debut in Sunday's 8-1 loss to the Rays. "I got to really know him, you know? He said, 'Next time you face me, look for that curveball.'"
With Wells and left-hander Charlie Furbush arriving Sunday in a deal for Doug Fister and David Pauley that also netted the Mariners a pair of top young prospects from the Tigers, the Mariners removed two-fifths of their starting rotation -- and two bullpen members, with Aaron Laffey sent down and Pauley dealt.
So it's probably not surprising that the Mariners went out and stumbled through Sunday's game while committing three errors, though manager Eric Wedge said there will be no letdown in the final two months despite trades obviously aimed more toward the future.
"You've got to trust your clubhouse and they've got to be men about it, they've got to be professionals," Wedge said. "They've got to understand this is where we're at right now. If we didn't go through the stretch we did, which we all have some control over, then it would be a different situation.
"But it's part of it. It's where we are right now as we build this thing. We're going to keep making tough decisions as we move forward. What we're not going to do is spin our wheels. I've told you that when I was hired. We're going to continue to make tough decisions and good decisions and build this thing."
That's why Zduriencik swapped the two final months of Bedard's pitching for a potential six years of control over each of the two young outfield prospects, both of whom are tearing up the Minor Leagues this season.
"We want to build something that Seattle and the fans, from year to year, can count on," Wedge said. "We're looking to be a championship club in the not-so-distant future and be able to sustain success. ... It takes talent and toughness to be a winner over the course of six months. We're making moves to work in that direction and we'll continue doing that."
