Rosenthal enjoys homecoming in I-70 Series
By Robert Falkoff / Special to MLB.com
KANSAS CITY -- Trevor Rosenthal is enjoying a homecoming, as the Cardinals open a two-game series Monday against the Royals.
Rosenthal is from Lee's Summit, Mo., about 15 minutes from Kauffman Stadium. When the Cardinals arrived from Los Angeles on Sunday night, Rosenthal was able to head to his parents' house for a home-cooked meal.
"I was involved in a pre-Draft workout at Kauffman, but that's the only time I played on this field," Rosenthal said. "It's fun to be here, a place where I've watched a lot of games."
Rosenthal didn't have to leave many tickets for Monday's game.
"Just for my parents and a couple of other close family friends," Rosenthal said. "Everybody else had already gotten their tickets, so that worked out well for me."
Rosenthal, who was a prep standout at Lee's Summit West High School, used to watch current teammate Carlos Beltran a decade ago, when Beltran roamed center field as a young star for the Royals.
"Coming back here is definitely a different feeling than when I go to other stadiums," Rosenthal said. "It's exciting, and hopefully we'll have a good series."
Envisioning Martinez as starter, Cards recall Marte
KANSAS CITY -- By sending right-hander Carlos Martinez to Triple-A Memphis and recalling right-hander Victor Marte on Monday, the Cardinals are paving the way for Martinez to work as a starting pitcher.
"We need to get him ready to start," manager Mike Matheny said. "We see him in the future as being a starter. He did a nice job for us coming out of the bullpen, but with the situation we've been having here with our rotation, he's a guy we'd like to have built up to use as an option later."
Martinez made seven relief appearances for the Cardinals following his May 3 promotion and struck out nine batters in eight innings, allowing four earned runs.
"It's good for him to see, coming straight out of Double-A, that his stuff plays to this level and he can get guys out," Matheny said. "He has also seen that he can get hit. It's a great reminder that he has work to do, and we sent him back with a laundry list of things to work on. Specifically, his secondary pitches and locating his fastball. He has to use the sinker and the four-seamer effectively, because he's not just going to be able to overpower guys."
Marte will attempt to provide a boost to the Cardinals bullpen, where he made 48 appearances a year ago, going 3-2 with a 4.91 ERA.
He was 1-0 with a 2.78 earned run average in 20 games for Memphis this season, fanning 23 in 22 1/3 innings. He had a team-leading 10 saves, which ranked fourth in the Pacific Coast League.
Cards to tab prospect Wacha for Thursday start
KANSAS CITY -- The Cardinals will promote rookie right-handed pitcher Michael Wacha from Triple-A Memphis to start Thursday night's game against the Royals. The Cards need another starter to replace John Gast, who is on the disabled list.
The team will announce a corresponding player move prior to Wacha's start.
Wacha -- the Cardinals' fourth-ranked prospect, according to MLB.com -- was scratched from a scheduled Monday start for Triple-A Memphis.
The 6-6, 210-pound Texarkana, Texas native is currently 4-0 with a Pacific Coast League-leading 2.05 ERA in nine starts for the Memphis Redbirds. Wacha has allowed just 35 hits in his 52.0 innings pitched this season for a .187 opponent's batting average.
• Right-hander Jake Westbrook, who has been trying to work through right elbow pain, threw Monday with no ill effects. "We did have a good day with Jake," Matheny said. "That's encouraging to hear."
• Carlos Beltran was in the lineup as designated hitter a day after experiencing left shoulder soreness, while Matt Holliday received a routine day off.
The use of the designated hitter in an AL park helped Matheny find some plate appearances for Matt Adams, who entered the day hitting .405 in just 42 at-bats, and started at first base.
