MIAMI -- Twins infielder Jeff Cirillo said Sunday he's about 80 percent certain he will retire at season's end.
Cirillo, 37, first made the comment on KSTP AM-1500 and then reiterated his feelings following the Twins' 7-4 victory over the Florida Marlins.
Cirillo said he wants to spend more time with his family. His wife, Nancy, and their three children live outside Seattle.
"If it was just me, I'd play as long as I can," Cirillo said.
Filling in for Justin Morneau at first base again, Cirillo went 0-for-5 and he said it occurred to him that it was probably his last game at Dolphin Stadium.
"I thought about it my last at-bat," he said.
Asked if his feelings have changed recently, as he's lifted his average from .207 to .271 since June 15 and shown he can hold down an everyday role, Cirillo said, "I'm not an everyday guy."
Pressed on that subject, Cirillo ended the interview. Both knees have bothered him this season and he had just played three games in the Florida heat.
"I'm sorry," he said. "I'm tired and a little punchy."
Twins acquire McDonald
The Twins made a trade, albeit minor.
The Washington Nationals sent them minor league outfielder Darnell McDonald for the right to keep Rule 5 draft pick Levale Speigner.
Teams must keep their Rule 5 picks on their major league roster or offer them back to their original team for $25,000. The Nationals traded McDonald to the Twins, allowing them to send Speigner to the minors.
McDonald, 28, will report to Class AAA Rochester on Tuesday. He was batting .315 with a .382 on-base percentage for Class AAA Columbus.
He was a first-round pick by the Baltimore Orioles in 1997. His only big league experience came in 2004, when he batted .156 in 17 games for the Orioles.
Mauer to first base?
Twins manager Ron Gardenhire said he considered putting Joe Mauer at first base Sunday, as a way to keep his bat in the lineup for the final interleague game.
Mauer said he'd rather catch.
