There were some eye-popping performances in the Dodgers minor-league system the last couple weeks, and I got to see three of the Rancho Cucamonga Quakes games in person, which was awesome.

There are some guys below folks should keep eyes on this season, as they could establish themselves as legitimate prospects with solid performances in 2013.

Triple-A Albuquerque Isotopes (4-2 & 5-2)

Player Of The Week – 4/22

Scott Van Slyke – 1B

.480/.536/.800/1.336, 2 HR, 6 RBI, 2 2B, 7 R, 1 SB, 3 BB, 4 K

Van Slyke is absolutely mashing the ball right now. Maybe he has a chip on his shoulder from being designated for assignment in the winter, maybe it’s his improved physique. Whatever it is, he’s doing everything right so far in Triple-A.

Player Of The Week – 4/29

Tim Federowicz – C

.571/.583/1.238/1.821, 3 HR, 3 2B, 1 3B, 8 RBI, 6 R, 2 BB, 4 K

Federowicz was the Pacific Coast League Player Of The Week and posted some ridiculous numbers. Those numbers, coupled with Ramon Hernandez’s struggles, helped Federowicz get recalled to the Dodgers on May 8.

Pitcher Of The Week – 4/22

Chris Withrow – RHP

2 IP, 1 H, 0 R, 0 BB, 4 K, 2 SV

Withrow, a failed starter, is having some success with the Isotopes. While he’s still walking too many hitters (6.4 BB/9), he’s getting strikeouts (12.1 K/9). He’s on the 40-man roster and could get the call if the Dodger bullpen continues to falter.

Pitcher Of The Week – 4/29

Steven Ames – RHP

4 IP, 3 H, 0 R, 1 BB, 1 K, 1 SV

Ames has been decent but unspectacular this season. His strikeout rate is way down (10.2 last season, 5.2 this season) and he’s giving up a lot of hits (15 in 12 innings), but he did spend some time on the disabled list. He’s also on the 40-man roster, so a call-up could be in his future.

Double-A Chattanooga Lookouts (2-3 & 1-5)

Player Of The Week – 4/22

Blake Smith – OF

.300/.364/.450/.814, 1 HR, 1 RBI, 2 BB, 6 K

Smith has struggled a bit this season in his second go-round in the Southern League. He’s played a lot of left field because of Yasiel Puig‘s presence and prototypical right-field profile.

Player Of The Week – 4/29

Joc Pederson – OF

.300/.323/.533/.856, 2 HR, 1 2B, 2 RBI, 1 BB, 7 K

Pederson is enjoying a fantastic start to his 2013 in the Southern League. There’s some chatter he could be the outfielder the Dodgers recall ahead of Puig, should the situation present itself. I wouldn’t be opposed to that.

Pitcher Of The Week – 4/22

Rob Rasmussen – LHP

5 IP, 2 H, 0 R, 2 BB, 8 K

Rasmussen was acquired for John Ely this winter and has done a nice job at the back of the Lookouts’ rotation. He’s not going to overpower hitters, but he’ll get his fair share of outs.

Pitcher Of The Week – 4/29

Rob Rasmussen – LHP

12 1/3 IP, 10 H, 4 R, 3 ER, 3 BB, 10 K

Rasmussen was the pitching star for the Lookouts. He’s small in stature, but he’s off to a great start in the Southern League so far. He’s a player to keep an eye on going forward, especially with Chris Reed and Andres Santiago struggling a little.

High-A Rancho Cucamonga Quakes (3-3 & 4-2)

Player Of The Week – 4/22

Jonathan Garcia – RF

.400/.429/.700/1.129, 1 HR, 3 2B, 2 RBI, 4 R, 1 SB, 0 BB, 4 K

Garcia is repeating the California League after a dreadful 2012. So far, he’s handling the league pretty well. He’s spent a lot of time as the team’s No. 3 hitter, but he was recently moved out of that spot. He has some decent raw power, but he swings and misses too much and he’ll need to improve that this season.

Player Of The Week – 4/29

Darnell Sweeney – SS

.333/.379/.556/.935, 2 2B, 2 3B, 2 RBI, 4 R, 3 SB, 2 BB, 7 K

Sweeney has been a nice surprise since being drafted in the 13th round last year. He’s now hitting third in the Quakes’ lineup after hitting leadoff most of the season. His fielding leaves a lot to be desired, though.

Pitcher Of The Week – 4/22

Duke Von Schamann – RHP

7 2/3 IP, 3 H, 1 R, 1 ER, 2 BB, 7 K

The 2012 15th-rounder is throwing well so far this season. He’s an inning-eating starter a Class-A team desperately needs. And with Ross Stripling being promoted, Von Schamann is the ace of the staff.

Pitcher Of The Week – 4/29

Garrett Gould – RHP

6 IP, 3 H, 0 R, 0 BB, 8 K

Gould was named California League Player Of The Week, although this honor could have gone to Jarret Martin (6 IP, 0 ER, 8 K). I actually saw Martin’s start in person, but it’s hard to argue against Gould’s performance.

Low-A Great Lakes Loons (3-4 & 1-6)

Player Of The Week – 4/22

Corey Seager – SS

.350/.350/.550/.900, 2 3B, 1 RBI, 3 R, 0 BB, 5 K

Seager did most of his damage in a Loons’ doubleheader sweep on April 21, but he did collect seven hits this week. He’s off to a slow start (.236/.323/.364/.687), but he’s a few days shy of his 19th birthday. This is a tough, aggressive assignment for a teenager, and he’ll be just fine going forward.

Player Of The Week – 4/29

Tyler Ogle – C/DH

.269/.345/.423/.768, 1 HR, 1 2B, 2 RBI, 2 BB, 4 K

There wasn’t much offense in Great Lakes, but Ogle one of the most veteran hitters the Loons have, and he had a decent week. He’s been splitting time with Eric Smith at catcher and DH.

Pitcher Of The Week – 4/22

Lindsey Caughel – RHP

6 IP, 2 H, 1 R, 1 ER, 0 BB, 6 K

Caughel has been the most consistent Loons’ pitcher this season. He was recently promoted to Rancho Cucamonga, and it’d be a surprise if he were to pitch in Midland again this season.

Pitcher Of The Week – 4/29

Carlos Frias – RHP

6 IP, 4 H, 0 R, 2 BB, 5 K

Frias led the Loons pitching staff and is making his first appearance with Great Lakes in his career. He’s pitched at Ogden and, surprisingly, Rancho Cucamonga. So far, he’s having success in the Midwest League.

The Dodgers have invited 12 players to their Winter Development Camp, which, after operating for its first five years of existence at Dodger Stadium, will move to Camelback Ranch due to construction at Chavez Ravine.

Zach Lee, Joc Pederson, Chris Reed, Onelki Garcia, Paco Rodriguez, Chris Withrow, Steven Ames, Matt Magill, Tim Federowicz, Matt Wallach, and newcomers Jeremy Moore and Rob Rasmussen makeup the 12 players selected by the organization.

Though Yasiel Puig was originally scheduled to participate in the camp, the Dodgers have opted to leave him with his Puerto Rican Winter League team, which is in the midst of a playoff run.

The Dodgers signed former Rays lefty J.P. Howell to a one-year, $2.75 million deal with incentives. Chad has details and analysis here.

I’m just glad the deal is for one year, especially given Ned Colletti‘s proclivity to give veteran bullpen guys long-term deals.

Jeremy Moore is one of five players to recently sign a minor-league deal with the club. Fabio Castro, Wilmin Rodriguez, Omar Luna, and Rusty Ryal round out the signings. Also, Scott Van Slyke was re-signed after being outrighted.

Alfredo Amezaga has signed his second minor-league deal with the Dodgers and has been invited to Spring Training. He was an NRI to Spring Training in 2010 as well.

The Dodgers have dealt John Ely to the Astros in exchange for minor-league lefty Rob Rasmussen.

Rasmussen, a SoCal native and UCLA graduate, was selected by the Dodgers in the 27th round of the 2007 draft but declined to sign and instead became a Bruin. He was drafted by the Marlins in the 2nd round of the 2010 draft and acquired by Houston in 2012 as part of the Carlos Lee deal.

John Sickels of Minor League Ball gave his thoughts on the deal for both teams here. A detailed report on Rasmussen, soon to be 24, can be found here from True Blue LA.

Rob profiles as a relief pitcher and adds some lefty depth to the organization. He’s been emphatic in his joy following the deal:

Speechless/incredibly excited to be a Dodger, truly a dream come true!

— Rob Rasmussen (@RasmussenRob) December 19, 2012

For a kid who lived 10 minutes from the stadium, and saw the likes of Piazza and Nomo, I couldn’t be happier than I’ve been all day today

— Rob Rasmussen (@RasmussenRob) December 20, 2012

Ely, who was merely organizational depth with the Dodgers and profiles as such going forward, was a small price to pay for a flier on a small lefty with some upside.

Scott Van Slyke has cleared waivers and been outrighted to AAA Albuquerque.

While Van Slyke is probably just a bench player or perhaps a one-year stopgap for a rebuilding team, I’m surprised nobody took a chance on him.

The Dodgers have signed former Angels third baseman Dallas McPherson to a minor-league contract with an invitation to Spring Training.

Over 10 seasons, McPherson owns a career minor-league line of .289/.370/.563/.933, but a career major-league slash line of just .241/.292/.446/.738 with a .316 wOBA while whiffing in an unseemly 32.1% of his plate appearances.

Over the past six years he’s amassed just 30 plate appearances and appeared in 22 games in the bigs. That doesn’t even tell the whole story though, as Dallas didn’t taste MLB ball in 2007, 2009, 2010, and 2012 due to a combination of injuries and ineffectiveness.

McPherson profiles as a classic AAAA player.

Ryu Hyun-jin: It was assumed he would not participate in the WBC and that assumption was confirmed today with the replacements being named.

— Dan (@MyKBO) December 21, 2012

The Dodgers have announced their minor-league staff for 2013.
