They include right-handed pitcher Michael Wacha, who is scheduled to start Tuesday evening's game in Cincinnati. Wacha, along with left-handed pitcher Tyler Lyons and right-handed pitcher Carlos Martinez were recalled from Double-A Springfield.
In addition, Brock Peterson, the Pacific Coast League's leading home run hitter, and infielder Ryan Jackson, were recalled from Triple-A Memphis and the contract of catcher Audry Perez was purchased from Memphis, adding him to the 40-man roster.
Wacha, 22, was 5-3 with a 2.65 ERA in 15 starts at Memphis this season. He is 2-0, 3.78 ERA in 10 games (four starts) for St. Louis, striking out 37 in 33 1/3 innings pitched, including seven in his four innings of relief on Wednesday, August 28 vs. Cincinnati.
Lyons, 25, was 7-2, 3.32 ERA for Memphis in 17 games (16 starts). The rookie lefty is 2-4, 4.73 ERA in nine games (eight starts) for St. Louis.
Martinez, 21, was a combined 6-3 with a 2.49 ERA in 16 starts between Springfield (AA) and Memphis this season. He is 1-1 in 12 games (one start) for St. Louis.
Peterson, 29, finished his 2013 All-Star campaign at Memphis with a league-leading 25 home runs and a league-best .531 slugging perentage. He batted .296 with 84 RBI (4th in PCL) and a .895 OPS (2nd). In 11 games with the Cardinals this season, the right-handed hitter batted .154 with two RBI.
Jackson, 25, batted .278 with three home runs and 34 RBI for Memphis this year, but has struggled in recent months. He has just one extra base hit since June 17 and a line of .234/.313/.239/.552 in his last 209 at-bats. Jackson is a solid and versatile fielder, committing just nine errors in 406 total chances. The right-handed hitter appeared in two games for the Cardinals earlier this season after playing in 13 games as a rookie in 2012.
Perez, 24, batted .210 with six home runs and 33 RBI in 82 games between Springfield and Memphis. The right-handed hitting catcher threw out 40 percent (31-of-77) of attempted base-stealers. He becomes the 20th rookie to appear on the Cardinals roster this season.
40-man players who appeared earlier this season for St. Louis but were not recalled are infielder Jermaine Curtis and pitchers Keith Butler and Victor Marte (on disabled list). Other 40-man roster players passed over who have yet to debut with St. Louis are pitchers Eric Fornataro and Jorge Rondon. With Perez' addition, the 40-man roster is currently full.
