Cardinals trade Rasmus for pitchers Jackson, Dotel

“Mixed emotions for sure,” Teahen said. “Obviously, I’m disappointed in the way it all worked out here. I wanted it to go a lot different.”

Frasor is a native of the Chicago area. The 33-year-old right-hander was 1-1 with a 2.98 ERA for Toronto in a setup role.

“He’s one of the top quality relievers in baseball,” Williams said. “He will fit in.”

Stewart was a third-round pick of the Cincinnati Reds in 2008. The 24-year-old started three games for the Blue Jays this season, going 0-1 with a 4.86 ERA. He was 5-5 with a 4.20 ERA for Double-A New Hampshire. Stewart will be assigned to Triple-A Charlotte.

“Zach Stewart has been on our radar for a long time, particularly last year when he was doing some special things in Double-A,” Williams said. “He will ultimately be in the mix in some way, shape or form. Most likely this year.”

To fill the open spot on the 25-man big-league roster, the White Sox recalled center fielder Alejandro De Aza from Charlotte and put him in the lineup for Wednesday’s game against the Detroit Tigers.

“The other part of doing what we did today, that allowed us to get De Aza in the lineup in center field,” Williams said. “That affords us to give Ozzie something more than honestly what (Alex) Rios is giving us. Rios is going to have to take a back seat now.”

The Rios has hit just .208 this season in 97 games despite a hefty long-term contract that will pay him $12 million this season and has two more years plus a club option remaining.

“Here’s what I told Ozzie: Do not worry about the size of the contract,” Williams said. “Just worry about putting the players (on the field) on a given day that can help you win. I’m sending a message to everyone.”
