The Cardinals thought they'd be getting back two starting pitchers this week, but they'll probably wind up with just one.
Right-hander Todd Wellemeyer, plagued by elbow issues that have cost him a couple of recent starts, is scheduled to return to the rotation in Detroit on Thursday.
The Cardinals were hoping left-hander Mark Mulder would be ready to join the big-league club this weekend in Kansas City, but that plan might have to be adjusted. Mulder was scratched from his scheduled rehab start with Class AAA Memphis on Monday due to a stiff back.
Mulder hasn't pitched in the majors all year as he continues his comeback from two shoulder surgeries. At his wit's end as his comeback dragged on without positive results, Mulder recently began throwing more sidearm than overhanded.
"We're satisfied that he's got his strength back," general manager John Mozeliak said before the latest setback. "It's more about finishing pitches and showing more command now."
NOTES AND QUOTES
--The Cardinals, playing in Detroit for the third consecutive year in interleague play, haven't won a regular-season game in either of the last two years against the Tigers. That doesn't count the Game 1 victory in the 2006 World Series, won by St. Louis in five games.
--OF Nick Stavinoha started as the designated hitter Sunday, the ninth major league debut for a Cardinals player this season.
--The Cardinals enter Detroit 11 games over .500 at 44-33. They didn't win their 44th game last year until July 20. They were 44-49 at that point.
--RHP Jason Isringhausen fanned two hitters to wriggle out of a bases-loaded spot in the 11th inning Sunday. It marked the first time since April 8 he had fanned more than one hitter in an appearance.
--Tuesday night's game is the start of 13 games in 13 days. The Cardinals have only one more day off before the All-Star break.
--RHP Braden Looper (.367) is the Cardinals' top hitter with 30 or more at-bats. But his bat will not be in the lineup Tuesday. He will be replaced by a designated hitter.
BY THE NUMBERS: 4 -- Number of runs Cardinals scored in three-game sweep by Kansas City. Number of runs they scored in each of the first two innings at Boston on June 21.
