ARLINGTON, Texas (AP) _ Mark McGwire's sore back felt good enough for him to be in the St. Louis Cardinals' starting lineup Friday night, but he was scratched following batting practice.

McGwire should be fine for opening day Monday. He homered Thursday in the Cardinals' final Florida game of the spring, giving him seven homers and 21 RBIs in 52 at-bats.

St. Louis played the Texas Rangers at The Ballpark in Arlington on Friday night. The Cardinals will play their Triple-A affiliate in Memphis on Saturday.
