He says he is trying to stay loose at the plate.
"I've been told to try easy," he said before Tuesday's second game of the White Sox series against the Toronto Blue Jays at Rogers Centre.
The White Sox third baseman made up for the slow start on Monday night when he drove in three runs with three hits, including the game-tying home run in the ninth and the game-winning triple in the 11th.
It also looks a little worse when the slump comes early in the season.
"I think if you go through a bad stretch in the middle of the season, you have enough numbers that it doesn't affect [the batting average] that much," Teahen said, "Especially when it's your first week with a new team you want to do a little bit too much and, with hitting, minute changes can affect a lot. So I'm just trying to stay loose and let my body work how it's supposed to rather than go out and try and do too much and be tight and not let my body work.
"I think early in the year you want to get off to a good start and switching teams and wanting to impress your teammates and the city or whatever right away. Luckily it's a long season and you can settle in."
