The latter case has come into play for two of the St. Louis Cardinals' brightest prospects.
On Tuesday, first baseman Matt Adams was placed on the disabled list of Triple-A Memphis with an elbow injury while star hurler Trevor Rosenthal has been moved onto the DL at Double-A Springfield, retroactive to Monday, July 2.
Rosenthal appeared in the Texas League All-Star Game, throwing a scoreless inning in the contest, held on June 28 in Tulsa. The 22-year-old followed that with a six-inning outing at home on Sunday against Frisco. Rosenthal fanned a season-high eight and was charged with three earned runs, which raised his season ERA to 2.97, still fourth-best in the Double-A circuit.
In five June starts, the Cardinals organization's Pitcher of the Month for May posted a 3.10 ERA, though he only managed a 2-2 record. Rosenthal fanned 26 and walked six in 29 innings last month.
On the season, he carries a 7-6 record with his innings-pitched total sitting at 88. Rosenthal threw 120 1/3 regular-season innings for Quad Cities in 2011 before starring for them in the Midwest League playoffs.
The 24-year-old Garcia has collected 11 extra-base hits, scored 23 runs and drove in 14 with a .258 average and .311 on-base percentage in 60 Texas League games this season.
Garcia knows his way around AutoZone Park as this is his second stint with the Triple-A Redbirds. The Venezuelan native spent most of June 2011 with Memphis and played well in a fill-in role, with a .300/.400/.400 line in 18 Pacific Coast League games.
However, events did not unfold as hoped. Siegrist was sidelined by a shoulder strain suffered in March and remained on the disabled list until May 6. He went back on Palm Beach's DL for another four weeks, from May 27 until June 24.
Since his latest return to the Florida State League, Siegrist has shown he is ready for Double-A. In 11 innings over two starts, he allowed just one unearned run on three hits. Siegrist fanned 11 and walked four. His overall record in six A-Advanced starts this season is 3-0 with a 2.30 ERA.
Springfield roster churn 100 percent
In an indication of the level of player movement sustained this season, following Rosenthal's injury, the entire current Double-A rotation began play this season at the next lower level, A-Advanced Palm Beach.
Siegrist is expected to make his Texas League debut on Friday night at Frisco. At this point, Palm Beach has not received a replacement hurler. A move may be made by what was to be Siegrist's next FSL start versus Bradenton on Friday.
Taking Garcia's spot with Springfield is another familiar face, infielder Vance Albitz. The 24-year-old made his Double-A debut during the June 12-23 period, when he went 0-for-7 with three walks.
Albitz has a .266 average with a .352 on-base mark in 43 games with Palm Beach this season, his first full year in the organization after being signed as a free agent last August from an independent league club.
Ahmady went onto Palm Beach's disabled list back on May 19 after suffering a hamstring injury. On the season, the right-handed hitter has a line of .295/.383/.411 in 129 at-bats over 38 Florida State League games. Ahmady's 15 doubles were the most in the FSL at the time of his injury.
