Arizona    

Jose Marte - Acquired from the Texas Rangers.

Acquired for starter Dustin Nippert, 26.

Marte is a 24-year-old reliever that reached High-A in the Texas Rangers organization and can really dominate with his stuff, but also lose the control of it and that's where the problem lies:  the 6'5'' athlete has struck out 174 in 152 innings in pro ball (over 11 K/9 rate), but also walked 92.  He is a power pitcher with raw secondary pitches.

Nippert, 6'7'',  is a right-handed thrower (sorry...giant!) that appeared in 36 games last season for Arizona, but never as a starter.  He has been part of a starting rotation all his pro career, even last season with their AAA club.  He is also a power pitcher that dial up his fastball up to 95 mph, but like many young pitchers, he needs to harness that power for it to be effective.  Hitters can either sit on a fastball they like or watch him walk them to first base.  He also throws a slow curve ball (77 mph) and change-up 85 mph).

Very good move by Rangers GM Jon Daniels and I think Keith Glab has the perfect explanation why:

Dustin Nippert stands 6-foot-7 and wields a fastball/curve combo that most pitchers can only dream about. Yet Nippert could never put it all together with the Arizona Diamondbacks.

Out of minor league options and carrying a spring ERA of 14.40, the contending Diamondbacks had little choice but to trade him, as they could not afford to wait for him to develop any longer on their major league roster.

The Texas Rangers took advantage of the situation, and acquired Nippert without losing any of their top 50 prospects as ranked by our sister site, LoneStarDugout.com. For their part, the Diamondbacks did well to even net a pitcher as promising as Jose Marte.
    
Atlanta    

Scott Thorman - Outrighted to Richmond (AAA).

Love my fellow Canadian, but left-handed pitchers give him hell and he has trouble making contact.  Even his late discipline has been mediocre (.260 in majors).

Ruben Gotay - Claimed off waivers from the New York Mets.

Baseball Digest Daily already has that one covered.
    
Baltimore    

Tike Redman - Outrighted to Norfolk (AAA).
Rocky Cherry - Right shoulder injury, 15-day DL (retroactive to March 22nd).

Why do I want to drink a Cherry Coke when I read that name?  I don't even like the darn thing.  Yes - they even have a wikipedia page for this one.  Enjoy.
    
Boston    

Edgar R. Martinez - Outrighted to Pawtucket (AAA).
Kyle Jackson - Outrighted to Pawtucket (AAA).

Repeated AA, but posted worse numbers (5.99 ERA, 70 IP, 69 H, 48 BB, 83 K) than the previous year (2.45 ERA, 36 IP, 32 H, 25 BB, 36 K) when he impressed.

Jose M. Capellan - Returned from Cincinnati Reds (Rule V draft).

Take the time to look at the numbers by following the link to the player's stats. Only four home runs in over 115 innings pitched in two years.

Here's a great nugget I found:

DH: It seemed like Jose Capellan took a positive step this year. What is your take on him?

JE: He started out really well. He was going deep into games. No one really roughed him up. Then he hit a stretch for three or four outings where things weren't going too well. And then the last couple starts of the year, he came back to his normal self and started battling. Between him and Doubront, those are two tough lefties. If you have to face them in a three-game series, you're going to have trouble winning that series.

DH: Does Capellan throw harder than Doubront?

JE: He's a high-80s guy. He throws pretty much the same stuff as Doubront, but he throws more of a 'slurve.' It's a 'slurve' that's more like a slider because he throws it so hard. One day he throws a slider and the next day he throws a 'slurve.' He makes it up. He keeps you guessing. You never know what to expect with him, but you know he's going to come out there and throw strikes. And he's one of those guys that gets better when he gets hit around. If he has a rough first inning, he might come back the next inning and shut you down for the rest of the game. When he gets out there he's sort of laid back. But once you start hitting him, he gets mad. He starts pumping it in there a little harder. As soon he gets the ball from the catcher, he's ready to throw. By the time the batter has one foot in, he's already coming set, ready to pitch.
   
Cincinnati    

Bill Bray - Optioned to Louisville (AAA).

From MLB.com:

Despite a solid spring, Baker noted Bray's inexperience and susceptibility to injury as two of the main factors in sending the 24-year-old to the Minor Leagues.

Andy Phillips - Assigned to minor league camp.
    
Cleveland    

Aaron Fultz - Released by the Cleveland Indians.
    
Colorado    

Steven Register - Returned from the New York Mets (Rule V draft).
    
Detroit    

Michael Hessman - Outrighted to Toledo (AAA).
    
Florida    

Jeff Conine - Signed by the Florida Marlins to a one-day contract and announced his retirement.

That's it for the 41-year-old: .285/.347/.443 batting line in his career.
    
Houston    

Reggie Abercrombie - Outrighted to Round Rock (AAA).
Chad Paronto - Outrighted to Round Rock (AAA).
   
Minnesota    

Francisco Liriano - Optioned to Fort Myers (A).
    
NY Mets    

Anderson Hernandez - Optioned to New Orleans (AAA).
    
NY Yankees    

Chad Moeller - Assigned to minor league camp.
    
Philadelphia    

J.D. Durbin - Outrighted to Lehigh Valley (AAA).

His stock fell last season after he started allowing more hits on top of the already high amount of walks he gave up.  He's a right-handed starter who has already fanned 651 batters in 731 innings pitched in the minors where he was used almost exclusively as a starter.  Left-handed batters really do a nice job sapping his confidence every time they come to the plate...

Ray Olmedo - Outrighted to Lehigh Valley (AAA).

If you ever get to see him play with the Lehigh Valley IronPigs (I don't know whether that's the coolest name ever or if I have to laugh because it's lame...help me out here...what do YOU think), please watch him field his position.  Incredibly soft hands and smooth all-around athletic abilities.  He is just born to be a shortstop.  His switch-hitting bat led the AAA team of the Blue Jays organization last season in batting average (.290) and he posted an OBP (.345) well above his career average (.318).

Chris Snelling - Outrighted to Lehigh Valley (AAA).

His minor league offensive performance (.311/.385/.472), never translated in the majors (.240/.357/.480), although his playing time has always been an issue.  At 26, he can still make a name for himself, but as a fourth outfielder, not a starting job.  The fact that southpaws feast on him doesn't help his case either.

Chris Woodward - Signed by the Philadelphia Phillies to a minor league contract.

It did not take long for the 31-year-old to find a job, hours after he was released by the Yankees.  He is versatile and provides above-average defense, mainly in the middle of the infield.  However, his career batting averages of .243/.299/.375 do not look attractive on paper...and at the plate...

Tim Lahey - Claimed off waivers from the Chicago Cubs.
    
Pittsburgh    

Chris Duffy - Shoulder injury, 15-day DL.
Jaret Wright - Declined minor league assignment and became a free agent.
Casey Fossum - Declined minor league assignment and became a free agent.
    
San Diego    

Jim Edmonds - Right calf injury, 15-day DL (retroactive to March 21st).

With Edmonds sidelined, Scott Hairston is scheduled to start in center field on Monday night and Paul McAnulty will start in left.

I'm amazed that they would even consider McAnulty for the job when you have Chase Headley who could more than likely out-hit him as a corner outfielder.  The main problem was his defense, but he is athletic and adapted faster than they expected. 

To his defense, McAnulty has a .301/.392/.481 line in the minors.

Denis Savage (Madfriars.com) had a good resume on both and reactions from manager Bud Black:

Bud Black had nothing but praise for Paul McAnulty and Chase Headley – two players angling for big league time with the San Diego Padres.

"Both of them will be major league players," Black said.

So far this spring, McAnulty is hitting .333 with four homers and 11 RBIs in 33 at-bats. He has also drawn eight walks compared to six strikeouts to post a .452 on-base percentage.

Headley is hitting a robust .371 over 35 at-bats, tagging a team-leading seven extra base hits and 12 RBIs.

"Mac has a real good shot at making the club," Black said in a race that also includes Jeff DaVanon and Jody Gerut.

With a little more than a week to go, the battle is still fierce and nothing is set in stone.

Headley, despite his tremendous spring with the bat has a little bit more of an uphill climb.

"I don't know if it is fair to Chase, making the conversion to left field and jumping from Double-A," Black said. "He has been very good at left."

With only 18 spring games under his belt, Headley may need more seasoning in Triple-A.

While he has battled the sun, most games are played at night and that circumstance provides different reads off the bat. It could take an extra second for an outfielder to pick up the ball – asking Headley to learn on the fly in the majors might be too much, but his bat is making the question interesting.
    
Tampa Bay    

Rocco Baldelli - Fatigue, 60-day DL.
Nathan Haynes - Claimed off waivers from the Los Angeles Angels.

The 28-year-old outfielder posted a 1.035 OPS in AAA in 171 AB (Angels org.).  He also made his major league debut last season and hit .267 in 40 games.  Bil James projects a .710 OPS for him in 2008.

The left-handed hitter could be a cheap solution in the outfield, with Rocco Baldelli out with a rare condition that makes it hard to recover from injuries and leaves him out of gas after simple physical exercises.  He could be a liability against left-handed pitching, but he gets on base against them nonetheless.  It's the contact-with-the-ball part that he struggles with.

From MLB.com:

Haynes, 28, is a natural center fielder with sprinter's speed. He came to camp aware of the fact that the Angels offered little hope of a job for Haynes with six proven Major League talents ahead of him on the depth chart after acquiring free-agent center fielder Torii Hunter.

"I'll just try to show what I can do, and hope that somebody out there sees that I can help them," Haynes said on Wednesday. "I know I can play at this level. It's just a matter of getting the opportunity."

Despite the circumstances, Haynes kept his spirits high and was having a solid spring, hitting .265 with six runs scored and four RBIs in 19 Cactus League games. He batted .267 in 40 games for the Angels in his rookie year of 2007.

"Nate can play," Angels third baseman Chone Figgins said of his close friend. "I hope he gets his chance to show what he can do, because he's a talented player with a lot of knowledge -- and he's tough.

"He helped me tremendously when I was struggling early last year. He knows my stroke as well as I do, and he was able to point things out to me from the dugout during games. Nate knows the game, and he knows how to play. I hope this works out for him."

Manager Mike Scioscia acknowledged Haynes' value as a backup outfielder during the club's ride to the 2007 American League West title.
