MINNEAPOLIS -- Twins left-hander Francisco Liriano was scratched from Wednesday's start with soreness and swelling in his left forearm.
Brian Duensing will make his first major league start for Minnesota, which will try to complete a three-game sweep of the White Sox.
Manager Ron Gardenhire said Liriano informed the team of his condition Tuesday, and no structural damage was found during an examination Wednesday.
Gardenhire said the plan is to have Liriano rest for a couple of days and throw a bullpen session this weekend. If all goes well, he would likely start next Wednesday in Cleveland.
Liriano has been a disappointment this season. The left-hander is 4-10 with a 5.56 ERA, second worst among American League starters.
