Jarret Martin SP LAD 4 Days

The Dodgers designated Martin for assignment on Saturday, the Los Angeles Times reports.

The Dodgers needed to clear a room on the 40-man roster for right-hander Mike Bolsinger, who was acquired from the Diamondbacks. The 25-year-old Martin pitched 54.2 innings for Double-A Chattanooga last season, posting a 3.29 ERA with 64 strikeouts and 48 walks.

Mike Bolsinger SP LAD 4 Days

The Dodgers acquired Bolsinger from Arizona on Saturday night in exchange for cash considerations, the Los Angeles Times reports.

Bolsinger spent the majority of 2014 at Triple-A Reno, but he did pitch in 10 games (nine starts) for the Diamondbacks, going 1-6 with a 5.50 ERA. The right-hander will provide some rotational depth for the Dodgers, who added him to their 40-man roster.

John Lannan SP COL 4 Days

Lannan signed a minor league contract with the Rockies, Matt Eddy of Baseball America reports.

Lannan made 25-plus starts in four straight seasons while with the Nationals from 2008-2011, but he's made just 25 appearances (20 starts) at the major league level in the past three years. The lefty spent some time in the Mets' bullpen early in 2015 and went on to post a 6.75 ERA and 1.82 WHIP in 14 appearances (12 starts) between High-A St. Lucie and Triple-A Las Vegas, but don't put it past the Rockies to give him a few starts in 2015.

Rey Navarro 2B BAL 4 Days

Navarro has agreed to a major league deal with the Orioles, Roch Kubatko of MASNsports.com reports.

Navarro hasn't quite lived up to expectations as a former third-round pick, but he'll be just 25 at the start of next season and posted a career-best .778 OPS between Double-A and Triple-A last season. Defense is Navarro's calling card, and he may be deployed most as a late-inning replacement in the middle infield in 2015, but he's also developed some pop in recent years (24 homers in last two seasons).

Rosell Herrera SS COL 4 Days

Herrera was moved from shortstop to center field in the Rockies' fall instructional program and is expected to play at the new position in 2015, MLB.com's Thomas Harding reports.

Due to the presence of Troy Tulowitzki at the major league level as well as the Rockies' sizable crop of middle infield prospects that includes luminaries such as Trevor Story and 2014 draft pick Forrest Wall, Herrera will transition to the outfield in an attempt to aid his rise through the system. The 22-year-old switch-hitter lost a bit of luster after posting a .302 on-base percentage while showing a steep decline in slugging at High-A Modesto last season, but a nagging wrist injury likely had much to do with the downturn in performance. The speedy, lanky (6-foot-3, 190 lbs.) Herrera should make a relatively smooth move to the outfield in what figures to be a repeat season at High-A. If health permits, it shouldn't be long before scouts salivating over his toolsy skill set once again.

Chris Nelson 3B PHI 4 Days

Nelson signed a minor league contract with the Phillies, Jeff Sanders of the San Diego Union-Tribune reports.

Nelson has appeared in 282 games at the major league level over the past five seasons, including 27 with San Diego in 2014. The 29-year-old doesn't have much power or speed to speak of, but he's a .308/.364/.479 career hitter at the Triple-A level and gives the Phillies some quality organizational infield depth.

Jonathan Galvez 2B SD 4 Days

Galvez signed a minor league contract with the Yankees, Jeff Sanders of the San Diego Union-Tribune reports.

Galvez hit .280/.354/.449 with 10 homers in 103 games with the Padres' Triple-A El Paso affiliate as a 23-year-old in 2014, but it wasn't enough to earn an invite to attend spring training with the Yankees. He had posted double-digit steals in each of his previous five seasons but didn't come close in 2014, getting caught five times in eight attempts.

Ivan De Jesus 2B CIN 4 Days

De Jesus signed a minor league contract with the Reds on Thursday.

De Jesus has bounced around between four organizations over the past three seasons (Dodgers, Red Sox, Pirates and Orioles), and will now join the Reds for the 2015 campaign. The former second-round pick has shown an ability to hit for average (.300) and get on a base at a good clip (.360) at Triple-A, making him a serviceable organizational depth option, but he's unlikely to see significant run with the major league club next season.

Josh Satin 1B/3B CIN 4 Days

Satin (wrist) signed a minor league contract with the Reds on Thursday.

A fractured wrist ended Satin's 2014 season and ultimately his seven-year tenure with the Mets as well, as the team removed him from its 40-man roster late last month. Satin, a .294/.394/.444 career hitter at the Triple-A level, can play first base, second and third, but it will likely take several injuries to Reds starters for him to get a chance with the big club in 2015.

Braulio Lara SP TB 4 Days

Lara signed a minor league deal with the Giants on Saturday, Baseball America's Matt Eddy reports.

Lara worked as a relief pitcher at Double-A and Triple-A last season in the Rays' organization, with little success. As a lefty specialist with shaky command, Lara holds little fantasy value, even in the deepest of leagues.
