Hendriks set to start for Twins on Saturday
By Rhett Bollinger and Jordan Garretson / MLB.com
With right-hander Carl Pavano on the disabled list, the Twins need a fifth starter on Saturday, and Hendriks has been impressive at Rochester.
The Australian right-hander is 5-0 with a 1.94 ERA in seven starts with the Red Wings. He has 42 strikeouts and 13 walks in 46 1/3 innings.
He's made the improvements the Twins were hoping to see from him when they optioned him after he posted a 9.00 ERA in four starts with Minnesota early in the year.
Twins recall righty reliever Oliveros
MINNEAPOLIS -- Right-hander Lester Oliveros was officially recalled from Triple-A Rochester on Thursday, and made his season debut with the Twins on Thursday night against the Phillies in Minnesota's 1-0 loss.
He allowed one run on one hit over 1 2/3 innings in relief of left-hander Scott Diamond. He also walked one and struck out one.
Oliveros, 24, posted a combined 2.70 ERA with 38 strikeouts and 12 walks in 36 2/3 innings split between Double-A New Britain and Rochester this season.
He said the biggest difference this season is his improved control, as he saw time in the Majors last season but struggled a bit. The hard-throwing right-hander had a 4.64 ERA with 13 strikeouts and 11 walks in 21 1/3 innings with the Tigers and Twins.
"I learned I needed better command," said Oliveros, who was acquired in the trade that sent Delmon Young to Detroit. "I needed to keep the ball down, and I went down to the Minors to work on my command."
Oliveros was recalled because the Twins have a depleted bullpen after P.J. Walters left Wednesday's start without recording an out. Walters was placed on the disabled list with inflammation in his right shoulder on Thursday.
"We used so much pitching last night we needed to add a little protection. He's been throwing very well down there for us"
Twins hope Walters learns from injury
MINNEAPOLIS -- P.J. Walters is learning a valuable lesson from his stint on the disabled list: Communicate before a minor injury becomes serious.
Walters, placed on the 15-day DL on Thursday with right shoulder inflammation, seemingly tried to grit his teeth through the issue in Wednesday's start. But he was pulled after failing to record an out on 15 pitches.
"You have to think about your arm, your career, the whole package when you get into these situations," Twins manager Ron Gardenhire said. "That's why we have trainers here. If you tell them you're barking a little bit, it's not like we're going to shut you down totally. We'll let them treat you and we'll go from there. They can put you on medication and get away from some of this stuff."
The right-hander said he was unable to get loose in the bullpen before taking the mound. Walters initially resisted Gardenhire's motion to end his outing early before eventually admitting his discomfort.
"You never want to leave the field like that," Walters said afterward. "You always want to be healthy and help the team. The last thing you want to do is have the bullpen throw nine innings -- offense puts up eight runs tonight and we lose. That's pretty much about as bad as you could have drawn it up."
Walters' injury is just the latest dent in an already banged up Minnesota rotation. He is 2-2 with a 5.40 ERA in seven starts this season, though his ERA sat at 4.42 before Wednesday.
"He's been throwing really well," Gardenhire said. "He wanted to go out there. ... But you got to get that Superman off your chest and get things taken care of.
"I think he'll be OK from here on out. He's learned a little bit."
