That's one factor why the A's decided to be cautious with their second-year closer and put him on the disabled list before Sunday's 6-4 win over Kansas City. Street left the second game of Friday's doubleheader with a strained groin.
"It's definitely really sore," Street said. "For me to pull myself out of a game, it's going to be pretty bad."
The only way the A's wouldn't have made the roster move is if Street felt dramatically better Sunday, which he didn't.
"(Street) is a young player, a max effort guy," A's trainer Larry Davis said. "It's his push-off leg. You can't expect him to compensate for that. He would end up hurting his arm. It's the prudent thing to do."
Street was scheduled to fly home to Oakland after Sunday's game to get an MRI on Monday. Davis said it's a Grade I strain, the least severe, which normally requires seven to 10 days to heal. He also said Street would be "darn close" to ready when the 15 days are up.
REPLAY: Jay Payton doubled home two runs in a three-run first inning Sunday against Kansas City, including Frank Thomas' first run scored from first base on a double this year. Eric Chavez and Mark Kotsay hit sacrifice flies as the A's built a 4-0 lead after two innings.
Kirk Saarloos (6-6) recorded six consecutive outs via groundballs to begin the game, and 14 of his 18 outs came on grounders, including two double plays. Joe Kennedy pitched two scoreless inning of relief.
BY THE NUMBERS: 15 -- The number of scheduled doubleheaders the A's had in a bizarre 1971 schedule.
QUOTE TO NOTE: "They're terrible. It can really ruin your month. If you go 0-for-8 or 0-for-9, it tears up your whole week. They aren't any fun. It takes a lot to get geared up for two games in a row." -- A's designated hitter Frank Thomas, on doubleheaders.
