Magneuris Sierra and Nick Plummer, two top outfield prospects in the St. Louis Cardinals system, were both injured Thursday night.

Magneuris Sierra and Nick Plummer, two top outfield prospects in the St. Louis Cardinals system, were both injured during Thursday night’s action.

Sierra sidelined

In the second game of Palm Beach’s Thursday double-header at Charlotte, Cardinals center fielder Magneuris Sierra was hit by a pitch and had to leave the game. On Friday morning, the high-A club placed the top-10 Cardinals prospect on the seven-day disabled list.

Sierra, who celebrated his 21st birthday one week ago, performed well in St. Louis’ camp this spring and seemed a candidate to jump over Palm Beach. Instead, he was assigned to the Florida State League to open the season and the leadoff man was off to a good start.

In 39 at-bats over nine games, Sierra had eight singles, a double and two triples. He scored nine runs, drove in three, drew five walks and was 2-for-4 in stolen base attempts. The left-handed hitter’s slash line is .297/.395/.432/.828.

When information about the nature of Sierra’s injury is disclosed, we will share it.

Sierra update: Saturday, April 15

Sierra is under concussion protocol, which is why he was placed on the DL, a Cardinals official told me. He would not comment on the duration of the stay.

Turgeon added

Sierra’s replacement on the Beach Birds’ roster is Casey Turgeon, who had been assigned nearby at Extended Spring Training (State College roster) after not making any of the full-season clubs out of spring camp.

A utility man able to play second base, third base and left field, Turgeon played sparingly across three levels in 2016, finishing at Springfield after also suiting up for Palm Beach and Peoria. The 24-year old first reached Palm Beach in 2015, where he spent most of that season. Over parts of two years at high-A, the right-handed hitter’s slash line is .236/.349/.332/.681.

Plummer hurt

On Friday, Peoria placed outfielder Nick Plummer on the seven-day disabled list with an oblique strain. The outfielder left Thursday night’s game after a second-inning strikeout.

St. Louis’ first round draft pick in 2015 was in his first game action since that season, after missing all of 2016 due to hamate surgeries on his hand. The 20-year old was still knocking off the rust, with two singles and a double in 15 at-bats to go with six strikeouts and three walks in his first six Midwest League contests. Plummer’s early slash line is .200/.368/.267/.635.

The Chiefs were already down one player after the retirement of outfielder Craig Aikin on Thursday, so the Class-A club was assigned two players from Extended Spring Training.

Davis is back

Infielder Matt Davis, who finished 2016 with the Chiefs, is back after not making a full-season club out of spring training.

The free agent signee last summer from VCU played in a total of 32 games across State College, Peoria and Palm Beach in 2016, with a slash line of .190/.261/.229/.489.

Billings boosted

The Chiefs added a much-needed outfielder in Shane Billings, also up from Extended.

St. Louis’ 13th-rounder in the 2016 Draft from Wingate University appeared in 50 games for the Appalachian League champions from Johnson City last summer. The 22-year old, a right-handed hitter, slashed .241/.269/.272/.541 in his maiden pro campaign.

With the Chiefs down to two healthy outfielders in Dylan Carlson and Vince Jackson, Billings may be thrust into the lineup quickly.
