Cardinals shuffle minor league roster deck

Five players are changing uniforms across four levels of the St. Louis Cardinals minor league system.

A series of roster moves rooted in Matt Carpenter's oblique injury earlier this week were executed across all four levels of the St. Louis Cardinals organization on Saturday. At least two more transactions are coming.

The Memphis Redbirds had been playing down one player since Steven Hill was called up on Wednesday to replace Carpenter. That deficit was addressed on Saturday as catcher Nick Derba was promoted from Double-A Springfield.

Derba, 26, is not known for his offense. This season he is batting .205 in 83 at-bats over 25 games with the S-Cards. The right-handed hitter also played for Memphis in a total of 25 contests in 2010 and 2011, with an average under the Mendoza Line.

In the corresponding transaction, to replace Derba in Springfield, catcher Travis Tartamella was promoted from the Class-A Advanced Palm Beach Cardinals.

Tartamella has struggled with the bat this season in the Florida State League, his third partial year at that level. The right-handed hitter is batting just .150 overall in very limited duty, just eight games this season. His OPS is just .427 and he has only two RBI.

Like Derba, Tartamella isn't reporting to his new level for the first time. In 2011, the 24-year-old first moved up to Springfield. His line was very similar to his 2012 start with Palm Beach After batting just .152 in 15 Texas League contests, Tartamella was returned to the FSL.

While Memphis returned to full 25-man strength, at the other end, Palm Beach is temporarily down two players. In what has to be concerning news, left-handed pitcher Kevin Siegrist was forced to return to Palm Beach's seven-day disabled list.

The 22-year-old went from the penthouse to the outhouse in less than 48 hours. Siegrist had a masterful outing on Thursday, his best of the short season. In just his fourth start since coming off the disabled list on May 6 after a shoulder strain, the Florida native threw five innings of one-hit shutout baseball against Tampa. He fanned four and walked just one, lowering his ERA to 3.54.

Being a starting pitcher for Palm Beach is a hazardous occupation. Siegrist becomes the club's sixth starter on the DL, joining Daniel Bibona, Seth Blair, Ryan Copeland, Carlos Martinez and Boone Whiting.

The fourth level of full-season ball, Quad Cites, also had a pair of transactions on Saturday.

After just nine days away from the Midwest League club's lineup, outfielder Anthony Garcia was activated from the disabled list of the Class-A River Bandits on Saturday. The 20-year-old native of Puerto Rico is hitting .276 on the season.

In the corresponding move, Roberto Reyes was transferred from Quad Cities to Extended Spring Training. The 23-year-old Dominican Republic resident spent about ten days on the DL a month ago due to a finger injury. The left-handed hitter ends his initial Midwest League stint with a line of .221/.283/.308 (BA/OBP/SLG) in 104 at-bats over 29 games.
