Brandon Morrow, in his last outing, got the ends of his fingers slightly more on top of the baseball at release, per Adair's gospel.  He threw, IIRC, a 1-hit shutout with 10k's (or something very similar). 

That outing is entirely reproducible.  Just a quick visual to twist the knife a bit.  ;- )

If he is indeed moving out for Brandon League and a prospect, we can see three completely different scenarios in which this helps the Mariners win their next pennant:

.

=== Prospect ===

Scenario 1 would be ... the "prospect" is Travis Snyder or somebody like him.  Snyder and Wallace aren't "prospects," of course, but we're chatting about the verbiage in a Twitter, right?

Here is the Hardball Times on the Jays' Top 10 actual prospects.  Commentary encouraged and solicited.  G, this means you ;- )

.

=== Closer ===

Scenario 2 would be ... Jack Zduriencik expects Brandon League to become the American League's next great short reliever.

League isn't a big name becasue (a) injured in 2007, (b) recovering in 2008, and (c) unjustly accused of wildness.

.............

League has two (2) legit wipeout pitches:

94-97 fastball that induces not only >9k per game, but also one of the most extreme groundball rates in the majors.  This puts League in a very rare category with Kevin Brown, Felix Hernandez, Erik Bedard, and only a couple of others.

Hitters miss FB's underneath the ball.  It's unpossible to throw a FB that gets both topped, and undercut.  Except for a few guys like Brandon League.

...

87 splitfinger / change that had run values of 5.92 and 2.65 (!!) the last two years.  By comparison, Bedard's curve sits around 2 runs above average per 100 pitches.   Felix has three pitches around 0.5, and his change is 2.0 to 2.5.

So you're talking about a man with a Kevin Brown two-seamer and a Kazuhiro Sasaki splitfinger.   (The photos show League holding circle changes, but whatever.) 

At this link, click the second Yanks vid and you'll see a pitch that looks a LOT like Daimajin's "thang," which is the more amusing since it's thrown sidearm.  (The sidearm delivery might explain why a circle change would dive like a Peregrine falcon.  Sasaki's change had a unique mechanic to it, also, and never was solved by AL hitters.)

Click the first vid on that site and you'll see a tasty 98 fastball that rips the catcher's glove off.  At the knees, inside black.

.

=== Starter ===

League started 40-50 games in the minors. 

This article gives a good feel for the potential League has to regain strength.  If Zduriencik tells us that the Mariners believe that Brandon League can start, I'm going to start weeping.

.

=== New Broom Sweeps Clean ===

If it really is just Morrow for League and a decent prospect, that goes into the "Closer" basket above. 

It's the most heavy-boldface indication yet that Zduriencik wants to win with his own young players.  And it's one more reinforcement of the idea that Zduriencik loves Special Talent (Milton Bradley, Cliff Lee, Aardsma and Lowe take over the bullpen, Sweeney & Griffey, etc etc).   SSI, of course, dearly approves of this bias.

...........

If the trade is Morrow-for-League, the M's are making a statement that they think League will be a great reliever.

If it's Morrow-for-League-and-prospect/pillar, that's another conversation.
