Sunday's Red Sox-White Sox matchups: Felix Doubront vs. Andre Rienzo

September 01, 2013 - 5:18 am

After posting a combined record of 14-39 in September over the last two years, the Red Sox will look to start off the final month of the 2013 season on a much more positive note Sunday afternoon as they take on the White Sox in the finale of a three-game series at Fenway. Lefty Felix Doubront will take the mound for Boston, while rookie Andre Rienzo gets the call for Chicago. After an atrocious start against the Yankees on Aug. 16 (seven earned runs in four innings), Doubront has rebounded nicely with two victories and three earned runs allowed over his last 14 1/3 innings. In his last start on Tuesday against the Orioles, Doubront was once again great, as the southpaw only gave up two earned runs and struck out seven, his most in a game since May 26 (eight strikeouts), over 6 2/3 innings. "I was working on my fastball. I was feeling good," Doubront said after the 13-2 victory. "Throwing the ball down was the most important thing for me the last two outings. It really was working today." In his last start against the White Sox, on May 21, Doubront held Chicago to two earned runs over six innings but got the loss after being outdueled by Jose Quintana, who no-hit Boston through 6 1/3 innings. Doubront has enjoyed success against the White Sox in his career, as the Venezuelan has a 2-1 record with a 3.00 ERA in three career starts. The second-ever Brazilian-born baseball player to play in the major leagues (Cleveland catcher Yan Gomes was the first in 2012), Rienzo was called up from Triple-A Charlotte on July 30 to start in place of Jake Peavy, who was scratched from that start and was traded to the Red Sox later that night. In six career starts, Rienzo has been solid, compiling a 1-0 record with a 4.21 ERA. He earned the first win of his major league career on Aug. 21, as the righty allowed just two runs over six innings of work and led the White Sox to a 5-2 victory over the Royals. However, Rienzo was unable to follow that up with anything similar in his last start, as he gave up seven runs (five earned runs) in six innings Monday against the Astros. With just 36 1/3 major league innings under his belt, Rienzo has no history with any members of the Red Sox lineup he'll face Sunday.
