Ahead of Sunday’s game in Atlanta, the St. Louis Cardinals announced outfielder/first baseman Jose Martinez has been placed on the 10-day disabled list and rookie outfielder Magneuris Sierra has been recalled from Palm Beach (A) and will join the team in Atlanta.

Martinez was batting .313 with a homer and 4 RBI in 20 games, ranking among National League rookie leaders in batting.

Sierra, 21, will be making his first appearance in the majors. He was the Cardinals Minor League Player of the Year in 2014 after leading the Gulf Coast League with a .386 batting average.

The Cardinals have had three of their outfielders suffer injuries in the past three days, including Stephen Piscotty, Dexter Fowler, and now Martinez. Fowler remains on the active roster and his availability remains day-to-day, while Piscotty and Martinez are both on the 10-day disabled list.
