Several injured Twins still trying to return

KANSAS CITY -- According to assistant athletic trainer Dave Pruemer, several Twins could be on their way to playing before the season ends.

Pruemer said Alexi Casilla could still return after playing just once since the end of July due to a strained right hamstring.

"The reports out of Minnesota is that he's feeling pretty good and running," Pruemer said. "So, we just need to get him back running the bases and see where we're at with him."

Tsuyoshi Nishioka is beginning to feel better and could pinch-run soon, but isn't quite ready to return to the lineup.

Justin Morneau and Denard Span are still recovering from concussion symptoms. Span was set to take batting practice on Tuesday and do field work. Morneau is still trying to string together multiple symptom-less days.

"Still trying to get there. Still trying to look at that and go from there," Pruemer said of Morneau. "A couple good days and then he seems to have one where it's just not quite right."

Injured starting pitchers Scott Baker, Nick Blackburn and Francisco Liriano all had good bullpen sessions on Sunday and workouts on Monday. Pruemer said the plan is for Baker and Liriano to throw another bullpen on Wednesday.

Cuddyer, Kubel among Twins back in lineup

KANSAS CITY -- The Twins saw the return of some regulars to the lineup for Tuesday's series opener against the Royals.

Michael Cuddyer, Jason Kubel, Ben Revere and Danny Valencia all started after missing Sunday's game.

Cuddyer was hit in the wrist with a pitch on Aug. 24 and has played sparingly since, while Kubel has been dealing with residual soreness in his previously sprained left foot. Cuddyer started in right field, with Kubel as the designated hitter.

"Cuddy, Kubel, both in the lineup. Cuddy went out and took some swings, feeling better," assistant athletic trainer Dave Pruemer said. "He's going to be sore, but he's able to play, and we'll go day by day with him. Same with Kubel."

Valencia missed Sunday's finale with the Tigers with a sore shoulder, but returned to his spot at third base. Revere, along with Brian Duensing and Alex Burnett, were dealing with the flu on Sunday, but all three are feeling better now, according to Pruemer.

Worth noting

• First baseman Justin Morneau left the team to attend to family matters and will rejoin the Twins when they return to Minnesota after the Royals series.

• Manager Ron Gardenhire said outfielder Brian Dinkelman left the team to attend funeral services for his grandfather. He will rejoin the team in Minnesota for the upcoming homestand.
