MINNEAPOLIS -- Reliever Matt Maloney cleared waivers and was assigned to Triple-A Rochester, the club announced Saturday.
Maloney, 28, posted an 8.18 ERA in nine appearances with the Twins. The left-hander struck out five, walked one and allowed two homers in 11 innings.
Maloney was designated for assignment on Wednesday to make room for Saturday's starter, P.J. Walters.
Maloney was originally acquired by the Twins on Oct. 31, when he was claimed off waivers from the Reds.
Morneau hits off tee, reports no issues
MINNEAPOLIS -- Twins designated hitter Justin Morneau reported no problems after taking 25-30 swings off a tee before Saturday's game against the Blue Jays.
Morneau, who is on the disabled list retroactive to May 1 with a sore left wrist, said he still doesn't have an exact timetable for his return, but is hopeful he'll be activated once he's eligible on Wednesday in Detroit.
"I'm pleased with the way it went and we'll continue along with the process and hopefully be ready," Morneau said. "I can't give a date, but I'm hopeful when I'm eligible to come off Wednesday I can play, but we'll see once I start swinging more, but I'm happy so far."
Morneau said he expects to ramp up to about 45 swings on Sunday before possibly seeing live batting practice on Monday. He added the cortisone shot in his wrist on Tuesday has helped, and that the key is making sure the discomfort doesn't flare up while swinging.
"The pain level doesn't matter, but if it's affecting my swing, then that's what we're trying to take care of," Morneau said. "If I can't swing the way I need to swing, then I'm not as effective as I need to be. I need to be able to do that. I felt like I was able to do that swinging today, so hopefully it'll feel better tomorrow and we'll keep moving forward."
Duensing, Swarzak candidates for spot-start duty
MINNEAPOLIS -- Twins manager Ron Gardenhire said he's stretching out left-hander Brian Duensing in case he needs to join the rotation, but that he's staying in the bullpen for now.
Duensing tossed three hitless innings in relief against the Angels on Wednesday to lower his ERA to 2.45 in 14 2/3 innings this season. He threw 45 pitches in that outing, so Gardenhire said he wouldn't need to be stretched out too much more to make a start.
"Duensing's been a starter around here," Gardenhire said. "He can pitch and he can get people out. He's really good in the 'pen, and I love him right where he's at. But if we can't get to the bullpen, then what good does it do out there? So we're trying to figure some things out."
Gardenhire added that right-hander Anthony Swarzak is also a candidate to be a spot starter, but that he'd rather keep him in the bullpen as a long reliever.
Swarzak threw three scoreless innings against the Angels on Thursday. He has a 3.09 ERA in 11 2/3 innings as a reliever this season and a 6.75 ERA in 14 2/3 innings as a starter.
"We like him in the 'pen," Gardenhire said. "He's been fantastic. He's in control of the game. We like him there. But can we spot start him? Absolutely. He's stretched out. But I really like him because he can come in and settle the game down."
Morneau pranks Mastroianni
MINNEAPOLIS -- Twins outfielder Darin Mastroianni was subject to a clever prank by Justin Morneau after collecting his first big league hit in Friday's 7-6 win over the Blue Jays.
Mastroianni picked up his first hit on a two-run single up the middle against Blue Jays right-hander Kyle Drabek in the fifth inning.
But when he received what he thought was the game ball from that single from Morneau after the game, his last name was misspelled and said the hit came on a dribbler against "Karl" Drabek in the wrong inning.
"He was trying to figure out what was going on," Morneau said. "He said it was the wrong pitcher, so I just threw it in the garbage. So the look on face -- he was in a little bit of shock -- it was pretty exciting. The real ball was in a glove in his locker. So that kind of made my night."
Mastroianni, who ended up going 2-for-4 with three RBIs, took the practical joke in stride, saying he'll keep both balls as keepsakes.
"That's going to stay with me, too," Mastroianni said with a laugh. "It'll be a fun little story later down the road."
Morneau said it's not a new trick, as it's something he's pulled on a few other rookies in recent years.
"I know I've done it a few times, because it's one of my favorite things to do," Morneau said. "I love doing that. I had the wrong pitcher, the wrong inning, a dribbler up the middle."
