Mark Trumbo traded to the Mariners

Whoa. You usually don't see big trades in the beginning of June, but that's exactly what happened Wednesday night. The Diamondbacks agreed to send Trumbo and pitcher Videl Nuno to the Mariners in exchange for catcher Welington Castillo, pitcher Dominic Leone, infielder man Jack Reinheimer and outfielder Gabby Guerrero.

The biggest pieced of the deal, obviously, is Trumbo. The big man will give Seattle some more power in addition to Nelson Cruz, who leads the team with 18 home runs. This season, Trumbo is hitting .259/.299/.506 with nine home runs, 23 runs and 23 RBI. Seattle ranks 28th in the league with 192 runs (only the White Sox and Phillies are worse), so it's obvious that the Mariners are looking to boost their offense. Safeco shouldn't affect Trumbo's power that much, similar to Cruz, but this move reeks of desperation. Maybe the Mariners catch lightning in a bottle, but Trumbo is what he is: power and not much else. I don't see Trumbo's fantasy arrow going up or down with this move.

The biggest offensive piece going back to the Diamondbacks is Castillo. The catcher started the year on the north side of Chicago, but the Cubs had no need when they acquired Miguel Montero and signed David Ross, Lester's personal catcher, over the offseason. This will be Castillo's third team this year; he's hitting just .162/.213/.279 with two home runs, eight runs and seven RBI. His best year was 2013, when he hit .274 with a .349 on-base percentage to go along with eight home runs, 41 runs and 32 RBI. Last year, he hit .237 with a career-high 13 home runs and 46 RBI. The move for Castillo will help cover the loss of Tuffy Gosewisch, who is out for the season with a torn ACL.

Moving Trumbo opens things up for everyday playing time for Yasmany Tomas. It's also good news for Jake Lamb, who is currently on a rehab assignment in Triple-A. Tomas can go to the outfield and Lamb can slide into third when he's ready. The move, I think, does more the fantasy value of Arizona's players than the biggest name of the deal: Trumbo.

Will the real Clay Buchholz please stand up?

(From Tuesday)

Yes. I'm still using bad, outdated cultural references from 2000. On Tuesday, Buchholz was dominant in an eight-inning shutout against the Twins, striking out eight, walking two and allowing just three hits. The solid performance improved the 30-year-old right-hander to 3-6 with a 3.82 ERA, 1.21 WHIP and a 70/18 K/BB ratio in 68 1/3 innings. Buchholz has now gone seven innings or more in each of his last four starts (six or more innings in six straight), including five consecutive quality starts.

Throw out a nine-run outing against the Yankees in Buchholz's second start of the year, and he owns a 2.77 ERA. It might have been easy to ignore Buchholz as a consistent roto option as early as a few weeks ago, but the fact is he's gone six innings or more in nine of his 11 starts. And eight of those have been quality starts -is it time we start viewing Buchholz as something more than a maddening underperformer?

2013 was Buchholz's best year. We saw improvement with a 23.1 percent strikeout rate (up from 16.1). This year, however, Buchholz is striking out a career-high 24.6 percent (up from a career mark of 18.5). He's also shown improvement in command with a 6.3 percent walk rate (down from 7.3). Groundballs are up, too, and his FIP (2.94), xFIP (3.11) and SIERA (3.15) all indicate that his 2015 success is real. It's just not showing up in wins and ERA right now, although the latter continues to go down with each passing start.

Buchholz's 11.5 percent swinging strike rate and 34.3 percent O-Swing% are both career highs, and he's also throwing more first-pitch strikes. If you bought into Buchholz's peripherals a month ago, congrats! We have seen Buchholz buck the trend of his ERA-xFIP split before in 2013, when he posted an elite 1.74 ERA. If you can't take the bad with the good, he could fetch you something decent. I'm sticking by Clay's side, however. This - his upside - is why you bought low on him after all.

Roto Roundup

Masahiro Tanaka was lights out in his return from right forearm and tendinitis, allowing just one run on three hits against the Mariners while striking out nine over seven innings. Tanaka only threw 78 pitches, but you know that the Yankees will take things slow with their prized starting pitcher and watch his pitch count to avoid another injury. Tanaka has been great when healthy, posting a 2.76 ERA, 0.82 WHIP and 33/7 K/BB ratio in 29 1/3 innings. But "when healthy" is the important takeaway here. Tanaka is always just another injury away, and he makes for a smart sell high.

Josh Hamilton is out four weeks with a Grade 2 strain in his left hamstring. The feel-good story ended before it really had a chance to start, although he did provide walk-off heroics last week. This is good news for the recently promoted Joey Gallo, who has homered three times in his first two games.

Marlon Byrd is out indefinitely with a fracture in his right wrist after getting hit by a Sean O'Sullivan pitch Wednesday. Byrd was actually looking like a smart veteran signing by the Reds. The 37-year-old has 10 home runs, 28 runs and 25 RBI. Now, the Reds are stuck with Skip Schumaker and/or Brennan Boesch, two players that should be left for owners in only the deepest of NL-only leagues.

Yasiel Puig - remember him? - will start a rehab assignment in High-A on Thursday. IT will be interesting to see how manager Don Mattingly rotates his outfield upon Puig's return.

The Red Sox acquired Alejandro De Aza from the Orioles, and are expected to activate Matt Wieters from the disabled list on Friday. Wieters hasn't played a game in 2015 after playing in just 26 games last year.
