Masterson has done his best to make the Red Sox regret that move ever since.Masterson looks to improve to 3-0 as a visitor on the Fenway Park rubber Sunday as the Indians try to salvage a four-game series split with Boston.Selected by Boston in the second round of the 2006 amateur draft, Masterson was a promising young arm who made 67 appearances -- 15 starts -- in the majors in 2008 and 2009 before the Red Sox made him the biggest piece in a deal with Cleveland for slugging catcher Victor Martinez. While Martinez played well in Boston, he departed via free agency after the 2010 season.Meanwhile, Masterson (1-2, 4.89 ERA) has become a stalwart of the Indians rotation.The right-hander posted a 3.21 ERA in 2011 -- best among Cleveland starters -- and his 12 wins were tied with Josh Tomlin for the staff lead. He's saved his finest work for the club that drafted him, going 4-0 with a 1.95 ERA and a .158 opponent batting average in four career starts versus the Red Sox.Masterson got off to a rocky start this season, going 0-2 with a 6.65 ERA through his first four outings, but has recovered to go 1-0 with a 3.05 ERA over his last three while pitching at least six innings in each. He gave up two runs while scattering six hits and five walks over six innings Tuesday in a 5-3, 10-inning loss to the Chicago White Sox.After cruising to an 8-3 victory in Thursday's series opener, the AL Central-leading Indians (18-15) have stumbled to 7-5 and 4-1 losses on Friday and Saturday, respectively. Now, they need a win to avoid their first three-game losing streak of the season.Meanwhile, the Red Sox (14-19) have gotten solid outings from starters Clay Buchholz and Felix Doubront to right the ship and post their first consecutive wins of May after a 1-8 start. After Buchholz allowed three earned runs in 6 1/3 innings Friday, Doubront limited Cleveland to one run and three hits over six."It's one of those things. We need to win and that's what we did (Saturday)," Red Sox catcher Jarrod Saltalamacchia said. "Two games in a row."Cleveland's three hits Saturday tied a season low."We couldn't get any offense going against Doubront. He was pitching to both sides of the plate," manager Manny Acta said.Boston's starting rotation had compiled an 8.29 ERA through the first nine games of May while averaging less than five innings per outing.Daniel Bard (2-4, 4.83) will try to extend the resurgence, but to do so he'll have to bounce back from a pair of subpar outings. The right-hander gave up five runs, six hits and four walks in seven innings of Tuesday's 6-4 loss at Kansas City, six days after surrendering four runs over 5 1/3 frames of a 4-2 home defeat to Oakland.Bard has never faced the Indians as a starter, but he's struggled mightily in 11 relief appearances, posting an 0-4 record and 8.64 ERA. He was charged with the loss in three of his four appearances versus Cleveland last season.Red Sox second baseman Dustin Pedroia is 5 for 8 with two doubles and four RBIs in this series and is batting .357 during a 13-game hitting streak, but he's 1 for 10 in his career against Masterson.
