Boston, MA -- (Sports Network) - Boston introduced a new late-game hero, as Jed Lowrie's two-out seeing-eye single to right scored Jason Bay with the winning run in the ninth frame, as the Red Sox advanced to the American League Championship Series with a 3-2 victory over the Los Angeles Angels of Anaheim in Game 4 at Fenway Park. Bay, the man who replaced much- maligned yet still terrorizing hitter Manny Ramirez in a three-team deal prior to the trade deadline, scored the winning run as part of a solid series. He hit a bloop tight to the right-field line that bounced just to the side of Reggie Willits, who was put into the game as a pinch-runner in the top of the frame. The ball caromed into the seats for a ground-rule double. Mark Kotsay followed with a line-drive shot that appeared destined for right field, but first baseman Mark Teixeira lunged to his left and made an acrobatic catch for the second out. Lowrie followed with the dribbler that rolled into right field just past the diving Howie Kendrick. Manny Delcarmen (1-0) retired two batters to pick up the victory, and Scot Shields (0-1) gave up the winning run in the ninth to suffer the loss. The Red Sox will now meet AL East rival Tampa Bay in the American League Championship Series starting Friday in St. Petersburg. Torii Hunter drove in the lone two runs for the Angels, while Bay and Lowrie each recorded a multi-hit game for the Red Sox, who won the best-of-five series, 3-1.

Final Score: Tampa Bay 6, Chicago 2

Chicago, IL (Sports Network) - B.J. Upton hit two solo homers, and the Tampa Bay Rays defeated the Chicago White Sox, 6-2, to clinch their first berth in an American League Championship Series in franchise history. Andy Sonnanstine (1-0) held the White Sox to two runs on three hits in 5 2/3 innings, with four strikeouts and a walk, to win Game 4, and in the process clinch this American League Division Series for the Rays, who are making their first postseason appearance. Tampa Bay will battle division rival Boston in the ALCS. The Red Sox edged the Los Angeles Angels of Anaheim, 3-2, on Monday to win their ALDS, also by a 3-1 tally. The Rays have homefield advantage for the ALCS by virtue of winning the season series with the Red Sox 10-8, and will host Game 1 on Friday. Carlos Pena went 3-for-4 with two RBI to supplement the early blasts by Upton, who homered three times in the last two games of the series for the AL East champions. Gavin Floyd (0-1) surrendered four runs on five hits for Chicago, including both of Upton's homers, in three-plus innings while striking out four and walking two to take the loss. Paul Konerko and Jermaine Dye each hit solo homers for the White Sox, which failed to get its two veteran stars -- Ken Griffey Jr. and Jim Thome -- a chance at their first World Series championship.
