In three games since returning from the disabled list, following a two-month comeback from a fractured right forearm, Chisenhall has drawn a pair of walks in his nine plate appearances. The 23-year-old third baseman had one walk in his previous 74 plate appearances this season.
"It's encouraging to see," Acta said. "It is always positive when a guy like him, that knows that part of his game needs to improve, is making a conscious effort to get better at it. But no one has asked him to walk. We're asking him to control the strike zone and swing at better pitches.
"By doing that, he's going to increase his ability to hit, and then the walks will show up. It's not something that he doesn't know. But it's encouraging to see that right away, him being back, and in the first few at-bats he's got a couple of good walks."
On the season, Chisenhall is hitting .278 with four home runs and 10 RBIs in 27 games for the Indians. A year ago, in his first taste of the big leagues, he hit .255 with seven homers, 22 RBIs and a .284 on-base percentage across 66 games. Chisenhall's OBP is up to .313 this year.
Among the 68 players with between 250-350 plate appearances in the big leagues over the 2011-12 seasons, Chisenhall is tied for last with 11 walks. Acta believes Chisenhall might have strayed from his approach last year due to putting too much pressure on himself.
"Guys come up here and they want to impress right away sometimes," Acta said. "They think that their opportunities will probably be limited, or they're being evaluated every at-bat. They just want to do well quick and they get out of their comfort zone."
