Cardinals pitcher Carlos Martinez struggled Sunday, allowing five earned runs on four hits and two walks in 3 1/3 innings while striking out one in his team's tie with the Twins.

Martinez came into the game with just one earned run allowed in 4 2/3 innings, but Sunday's dud gives him a 6.75 ERA in eight innings. He's competing for the fifth spot in the rotation this spring.

"Carlos also had two extremely impressive outings, and this one wasn't as bad as it looked," manager Mike Matheny said. "The door's open. It's just competition. We're truly trying to watch with an open mind to see what looks the best. Obviously we have a lot of games left, a long way to go to get everybody there."
