McLouth scratched from lineup

Pirates center fielder Nate McLouth has been scratched from the starting lineup for today's game against Cincinnati with tightness in his hamstring, according to a team source. Nyjer Morgan, who is competing with McLouth for the regular-season job, will play center and lead off.
Here is the revised starting lineup for both teams (someone tell me how National League pitchers are supposed to be effective with the bat when teams are using the designated hitter in spring training):

Andrew McCutchen, LF
Freddy Sanchez, DH
Adam LaRoche, 1B
Xavier Nady, RF
Jose Bautista, 3B
Ronny Paulino, C
