Worth noting

• The opening created in Memphis' rotation upon Gast's promotion will be filled by right-hander Boone Whiting. Whiting will make his Triple-A debut on Tuesday. In six starts for Double-A Springfield, Whiting was 3-2 with a 2.93 ERA, 34 strikeouts and seven walks.

• Former Cardinal Rick Ankiel was back at Busch Stadium on Monday, this time as a member of the Mets. New York signed the recently-released outfielder on Monday and wasted no time getting Ankiel in the lineup. Ankiel, who began the season with Houston, hit seventh and started in center field in his Mets debut.

• Matheny labeled Monday as a "semi-scheduled" day off for shortstop Pete Kozma. Wanting to make sure Daniel Descalso gets periodic starts, Matheny chose Monday as an ideal day to get Descalso's left-handed bat in the lineup.

• At 10 a.m. CT on Tuesday, the Cardinals will begin selling tickets for Chelsea soccer team's public training session, which is scheduled for 7 p.m. on May 22 at Busch Stadium. Chelsea and Manchester City will play a game at Busch Stadium the following night. Tickets to the training session are $20 and will be available at cardinals.com/soccer, the Busch Stadium Box Office or by calling 314-345-9600.
