Rookie Mookie Betts and the Boston Red Sox are enjoying quite the road trip. Betts and Boston look to continue their good fortune on Saturday when they visit the Rays in the second contest of their four-game series. After belting a solo homer on Monday, Betts blasted his first career grand slam four nights later as the Red Sox cruised to an 8-4 triumph and improved to 3-1 on their 10-game road trip.While Betts has enjoyed a productive week, Yoenis Cespedes continued his sizzling August by driving in a pair of runs to increase his total to 22 in the month. Tumbling Tampa Bay is singing a different tune as it has dropped nine of its last 13 contests after opening a 10-game homestand against its American League East rivals with a thud. The Rays need to make hay at Tropicana Field to keep alive their faint postseason hopes, but their subpar 29-37 mark at home this season doesn't provide much room for optimism.TV: 7:10 p.m. ET, NESN (Boston), SUN (Tampa Bay)PITCHING MATCHUP: Red Sox RH Allen Webster (3-2, 5.81 ERA) vs. Rays RH Jake Odorizzi (9-11, 4.23)Webster suffered his first loss since Aug. 2 after yielding season highs in both runs (six) and hits (eight) while pitching just 4 1/3 innings in an 8-6 setback to Seattle on Sunday.
