(Sports Network) - Having snapped a five-game losing streak to the Boston Red Sox on Saturday night, the Texas Rangers shoot for back-to-back victories at Fenway Park when the clubs collide in the third of a four-game set this afternoon. Trailing by four runs, Texas picked up a crucial home run from Sammy Sosa, his 14th of the season and the 602nd of his career, giving it the lead as it moved on to the 5-4 triumph. Sosa finished with two hits and a pair of runs scored, while Frank Catalanotto tallied three hits. Kenny Lofton and Marlon Byrd each registered a couple of hits as well. Ron Mahay ended up with the victory for the visitors as he pitched two scoreless innings in relief of Robinson Tejeda who managed to go just four innings, allowing four runs on five hits and six walks. Eric Gagne posted his ninth save of the campaign as well. Josh Beckett was saddled with the loss for the Sox, his second in 13 decisions in 2007. Beckett was touched for five runs on 10 hits over five innings, fanning four without a single walk to his credit. Kevin Youkilis, now batting .326 on the season, scored twice and knocked in two as he worked a trio of walks on the night. Alex Cora contributed a double and a triple in the setback as well. Righthander Kameron Loe faces off against the Red Sox for the third time already this season as he takes the hill for Texas this afternoon. Loe, who is 1-1 in his four-year career versus Boston, last pitched on Monday against Detroit on the road and managed to post his third consecutive victory in as many opportunities. The California native, who began the campaign a disappointing 1-6, limited the high-powered Tigers to just two runs on seven hits and a pair of walks, all while striking out just a single batter in seven innings of work. Already with more wins at this point than all of last season when he was just 3-6, Loe brings an ERA of 6.02 into the weekend through 18 appearances. As for the Sox, Julian Tavarez searches for his third win in the last four outings when he counters for the home team. The 15-year veteran, who has suffered only one loss in the last eight games, was knocked out after only 4 1/3 innings versus Seattle on the road on Monday, allowing six runs (three earned) on six hits and a trio of walks. In his two previous games versus the Rangers this season, Tavarez has thrown 9 2/3 innings and given up a total of eight runs on 12 hits, while issuing six walks. For his career, the righthander is 2-4 with a lofty 6.20 ERA against the squad from Arlington. Over the last week of play Lofton has shown significant signs of life with 10 hits in 22 at-bats and has also stolen four bases for the Rangers. Although he has struck out five times in six games, Byrd has added nine hits, leading to seven RBI and five runs. While he has a mere four hits in his last six games, Youkilis has produced a team-high seven RBI and scored three times himself, thanks in large part to six walks, matched J.D. Drew in that department of the last week as well.
