BALTIMORE -- Two days before the White Sox travel to Toronto, manager Robin Ventura opted to change his starter for the opener of a three-game series with the Blue Jays. Andre Rienzo was originally scheduled to start, but after he lost his last five starts, while allowing 22 runs in 22 1/3 innings, the White Sox are opting to go with Scott Carroll on Thursday.
Carroll began the season as a starting pitcher and was moved to the bullpen after five starts. He has a 1.83 ERA and .224 batting average against in six relief appearances.
"Scotty's been throwing great," Ventura said.
In five starts to begin the season, Carroll went 1-3 with a 6.15 ERA.
Meanwhile, Rienzo began the season relatively well. In his first six starts, he went 4-0 with a modest 4.11 ERA before unraveling in his last five outings. After allowing four earned runs in just 4 1/3 innings during his most recent start against the Twins on Saturday, Rienzo's ERA climbed to 5.86.
Ventura saw Carroll find enough consistency out of the bullpen to warrant his return to the rotation. This move, he hopes, will let Rienzo do the same.
"At this point, it's probably better for Rienzo to take a break," Ventura said, "go to the bullpen and figure it out."
Johnson, Montas named to Futures Game rosters
BALTIMORE -- The White Sox will be represented in both dugouts at the 2014 SiriusXM All-Star Futures game in Minneapolis next month. Micah Johnson, a second baseman for Triple-A Charlotte, and Francellis Montas, a right-handed pitcher for Class A Advanced Winston-Salem, were both named as participants for the game on Tuesday for the U.S. and World teams, respectively.
Johnson, the club's No. 2 prospect, according to MLB.com, began the season at Double-A Birmingham and was promoted after batting .329 in 37 games. In 24 games since joining the Knights, Johnson is batting .279 with five extra-base hits and four steals.
He was a ninth-round selection out of Indiana in the 2012 First-Year Player Draft.
Montas is the club's 16th-ranked prospect, and the 21-year-old has been dominant for the Dash this season. He has made nine starts this season and posted a 1.64 ERA with 51 strikeouts and just 11 walks. He was acquired by Chicago from the Red Sox last season in a trade centered around starting pitcher Jake Peavy.
Montas made his Minor League debut as a 17-year-old in 2010 and hit triple-digits with his fastball a year later, but he has never had a full season with an ERA better than 3.65.
The SiriusXM All-Star Futures Game, which is now in its 16th year, features the top Minor League prospects competing in a nine-inning contest as part of Taco Bell All-Star Sunday. Team USA, which has won each of the last four contests, leads the all-time series, 9-6. The game will begin at 4 p.m. CT and can be viewed live on MLB Network and MLB.com.
Ventura remains confident in Belisario as closer
BALTIMORE -- A day after Ronald Belisario allowed a walk-off three-run home run to Chris Davis that sealed a 6-4 loss to the Orioles, the White Sox went right back to their closer Tuesday night.
Manager Robin Ventura still views Belisario as the team's closer and has confidence that he can become a more consistent ninth-inning option.
"You do have the ability to change it any time you want, but right now I would say, if we're winning tonight, he's going back out there," Ventura said before his club's 4-2 victory. "That's just the way it is."
Belisario took over as the closer when Matt Lindstrom was placed on the disabled list on May 20 with an ankle injury. At the time, Belisario's ERA sat around 4.00, but after allowing three runs in the ninth on Monday, it ballooned to 5.50.
"I have to get my job done," he said after Monday's loss, "but things happen."
It was his fourth blown save of the season and third since becoming the full-time closer.
"For any guy that goes into that role, it becomes different," Ventura said. "Whether somebody else can do it right now I don't know, but I'm going to find out if he can do it."
Ventura has been relatively impressed with Belisario's performance in the new role, especially considering the circumstances.
Monday night's loss was the product primarily of one bad pitch. Other times, his defense has let him down. He hasn't had control issues -- he's only walked three batters since May 13 -- and Monday was just the third time since April that he's allowed multiple runs in an outing.
"It's not always the pitcher's fault," Ventura said. "I have confidence in him that he can put that behind him and continue to throw."
On Tuesday night, Belisario entered the ninth inning after Scott Downs allowed a leadoff single. After getting J.J Hardy to ground into a fielder's choice, Belisario gave up two straight hits, including Delmon Young's RBI single that made it 4-2. But Ryan Flaherty hit into a game-ending double play to give Belisario his eighth save.
Third to first
• With a hit on Tuesday, outfielder Adam Eaton reached safely in his 19th consecutive game -- the longest for a White Sox lefty since outfielder Juan Pierre reached in 18 straight in 2011.
• The White Sox loss to the Orioles on Monday was their eighth straight on the road.
"This is just not getting that run, that extra hit that we need," Ventura said, comparing this year's skid to some of last year's struggles. "There's a lot of different things that go into it. It's not as sloppy as last year."
• Adam Dunn was back in the lineup on Tuesday as the designated hitter. He needs one home run to pass Carl Yastrzemski for 35th on the all-time list with 453.
