(BaseballStL) -- The Cardinals have added six players to the roster. One of the call ups from Memphis, Michael Wacha, will be the starting pitcher for Tuesday's game in Cincinnati. Here’s the list of players joining the roster:
Michael 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 (4 starts) for St. Louis, striking out 37 in 33.1 innings pitched, including seven in his 4.0 innings of relief last Wed. (Aug. 28) vs. Cincinnati.
Tyler 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 9 games (8 starts) for St. Louis.
Carlos Martinez, 21, was a combined 6-3 with a 2.49 ERA in 16 starts between Springfield (AA) and Memphis (AAA) this season. He’s gone 1-1 in 12 games (one start) for the Cardinals.
Brock Peterson, 29, finished his 2013 All-Star campaign at Memphis with a league-leading 25 home runs and a league-best .531 slugging pct. He also batted .296 with 84 RBI (4thin PCL) and a .895 OPS (2nd). In 11 games with the Cardinals this season, the right-handed hitting Peterson has batted .154 with 2 RBI.
Ryan Jackson, 25, batted .278 with 3 home runs and 34 RBI for Memphis this year, finishing third on the team in both hits (123) and games played (121). Jackson committed just 9 errors in 406 total chances and finished 2nd among PCL fielding pct. leaders at shortstop (.978). The right-handed hitting Jackson appeared in two games for the Cardinals earlier this season after playing in 13 games as a rookie in 2012.
Audry Perez, 24, batted .210 with 6 home runs and 33 RBI in 82 combined games with Springfield and Memphis. The right-handed hitting catcher threw out 40 pct. (31-of-77) of attempted base-stealers. He becomes the 20th rookie to appear on the Cardinals roster this season.
The Cardinals also recalled outfielder Adron Chambers from Memphis (AAA) and activated catcher Tony Cruz (left forearm) from the 15-day disabled list prior to Sunday’s game.
The moves come at a time when the starting rotation is showing major signs of fatigue. Only Joe Kelly has been consistent over the past few weeks. Wacha makes the start tonight, and Tyler Lyons is likely to find his name penciled in for a start soon if Lance Lynn and
Shelby Miller continue to struggle. Carlos Martinez will probably be used solely as a reliever. Martinez has been effective as a starting pitcher at Memphis, but not in St. Louis. Brock Peterson gives them some pop off the bench as a pinch hitter. Ryan Jackson may get some time at shortstop with Pete Kozma struggling mightily at the plate. Audry Perez is not likely to get much playing time unless the game is a blow out. He’ll be used strickly as an insurance policy in case something should have happen to both Yadier Molina and Rob Johnson.
