Sizemore, who primarily played second base with the Tigers, has improved steadily at third. More important, he's hit well while learning a new position and made a nice play in a 7-6 loss on Saturday when he leaped into the stands to snare a foul ball.
Sizemore finished Saturday with 10 hits in his past 32 at-bats. He had three home runs, six RBIs and four multi-hit games, as he flashed the offensive ability that made him a heralded prospect in the Tigers' system.
Sizemore, who was traded from the Tigers to the A's on May 27, is learning where to position himself at third, manager Bob Melvin said.
"The more comfortable he gets, there more entrenched he'll get there," Melvin said. "It's difficult to give him a day off because he's been an offensive force for us. Now, he's hitting in the middle of the lineup. He's gone from the new guy here, not sure he'd be able to play the position, to a guy we count on every day."
