Scott Sizemore just can't stay healthy.
The Oakland A's infielder tore his left anterior cruciate ligament for the second year in a row, and he'll need another season-ending knee surgery.
"It's just awful," manager Bob Melvin said. "He plays with such heart. He cares so much, He wants to win. This is a difficult one."
In 2012, Sizemore was penciled in as the Athletics' starting third baseman, but he hurt his knee the first day of spring training and was lost for the year.
He returned to action this spring, and he earned a spot sharing second base with Eric Sogard. In just his second appearance of the season, Sizemore re-injured the knee chasing a shallow fly ball in the outfield Tuesday.
Sizemore, 28, went 1-for-6 this year. He's a career .238 hitter in parts of three major league seasons with the Detroit Tigers and Oakland.
Sogard now steps in as the regular second baseman for the A's, who recalled infielder Andy Parrino from Triple-A Sacramento. In six minor league games this season, Parrino hit .174 (4-for-23) with one RBI.
Parrino, 27, played a combined 79 games for the San Diego Padres the past two seasons, hitting .200 with one homer and 10 RBIs. He was acquired in the offseason deal that sent right-hander Tyson Ross to San Diego.
