In 29 games since May 1, entering Tuesday, Sizemore batted .179 with three home runs and 10 RBIs. In that span, he has just eight walks and has whiffed 43 times.
That stretch includes a stint on the 15-day disabled list after Sizemore injured his knee sliding into second base in a win against Tampa on May 10. Because of that injury -- and the microfracture surgery that forced Sizemore to miss all but 33 games in 2010 -- Acta prefers to wait until Sizemore shakes off the rust until he draws any definitive conclusions.
"The best thing out of all that is that he feels good," Acta said. "He's in a good spot physically, and if he is, he'll get through it and help us out. That's the main thing for us."
Overall, Sizemore's average sits at .233. In 41 games, he has seven home runs and 19 RBIs. That's a far cry from the player whose average season from 2005-08 was .281 with 27 homers and 81 RBIs.
To right the ship, Sizemore took extra batting practice Tuesday afternoon despite receiving the night off for the second contest of the team's three-game Interleague set with Colorado. Acta said Sizemore has been working closely on his mechanics with new hitting coach Bruce Fields.
"He's working with Bruce about not swinging across his body too much and using the whole field," Acta said. "He was stepping into the plate a little too much, which he normally does, but not as pronounced. ... Guys get into those type of problems of chasing and expanding the zone."
