Cards Minor League Transactions: August 22

News on seven St. Louis Cardinals minor leaguers – injuries, promotions, moves and returns. Jonathan Cornelius leads the way.

Cornelius’ Chance

Left-hander Jonathan Cornelius has been called up to Triple-A Memphis from Double-A Springfield for the first time. A starter at Double-A, the 26-year-old may be used as a reliever or swingman for the Redbirds, as his new club appears to have a full rotation.

In 25 games, 24 starts, covering 144 innings this season, Cornelius has logged an 11-9 record and a 4.00 ERA. He struck out 90 and walked 38, holding Texas League batters to a collective .258 average.

Sherriff Returns to Springfield

The brief Triple-A introduction of left-handed reliever Ryan Sherriff ended on Friday with his return to Springfield.

Since his promotion to Memphis on August 10, Sherriff made four relief outings for the Redbirds, recording a 6.75 ERA (three earned runs in four innings, including one home run). The 24-year-old logged four strikeouts and issued just one free pass.

Lefty Sabatino Promoted

The Palm Beach bullpen is getting strengthened with the Friday addition of left-hander Steve Sabatino.

The 24-year-old spent just over 12 months on the Peoria Chiefs roster, having joined the club on August 11, 2013. This season Sabatino has a 5-2 record with a 1.94 ERA, four holds and four saves. He struck out 47 and walked 11 in 41 2/3 innings while holding Midwest League batters to a .195 batting average.

All-Star Herrera Beached

Acquired from Cleveland just over a year ago in the Marc Rzepczynski trade, shortstop Juan Herrera earned a Midwest League all-star spot with Peoria. On Thursday, the 21-year-old was rewarded with a late-season promotion to the Palm Beach Cardinals.

In 379 at-bats over 101 MWL games, Herrera generated runs and produced them, too. He scored 50, drove in 56 and swiped 27 bases in 40 attempts. His Peoria line was .274/.320/.364.

Diaz Back on Shelf

The once-promising, but now disappointing rookie professional season of shortstop Aledmys Diaz is ending as it began – on the disabled list. This time, it is his legs, a hamstring injury, rather than his shoulder.

After coming off the DL for the second time with Springfield due to the ongoing shoulder problems, Diaz was re-assigned to Palm Beach on August 6. The 24-year-old appeared in just 13 Florida State League games, all as designated hitter, with a line of .227/.352/.409.

With just over three years remaining on his four-year contract signed this spring, Diaz remains on the Cardinals’ 40-man roster.

Garcia Rebounding

Third baseman Ronnierd Garcia has been promoted from the State College Spikes back to the Peoria Chiefs. It is the 21-year-old’s second stint in the Midwest League, as he batted .167 over nine games earlier. Garcia also appeared in the three games at Palm Beach as an injury fill-in.

In 87 at-bats over 27 games with State College, the right-handed batter hit one home run and drove in 11. His New York-Penn League line was .230/324/.345.

Don’t Forget Aardsma

On Wednesday, the Cardinals returned reliever David Aardsma to the active roster of Memphis. The right-hander had been on the Triple-A club’s DL since June 17 and this week made two one-inning rehab appearances in the Gulf Coast League.

Pitching very well before his groin injury that required surgery (0.91 ERA in 29 2/3 innings), the 32-year-old has less than two weeks to show he could be ready help out the big-league club in September. Signed to a minor league contract in late March, Aardsma is not on the Cardinals 40-man roster.

Update: Valera Changes Course Again

After Friday night’s game, infielder Cesar Valera was reassigned to Palm Beach from Peoria, reversing a move made on July 24. The 22-year-old has had two stints with both Class-A clubs this season, having begun with Peoria before being promoted to Palm Beach for the first time on June 24.

With the Chiefs this time, the right-handed hitter’s line in 89 at-bats was just .157/.242/.202.

Peoria was not immediately assigned a replacement. Palm Beach is likely assigning an infielder to Springfield, but if so, it has not yet been announced.

Update #2: Vargas to Springfield

Saturday’s move from Palm Beach to Springfield is infielder Ildemaro Vargas. Having spent the entire season in the Florida State League, the 23-year-old has appeared in 112 games, logging 431 at-bats. The Venezuelan has driven in 40 and scored 46 runs with a slash line of .241/.271/.292.

This will be Vargas’ Double-A debut.
