ST. PETERSBURG, Fla. -AP- Drew Smyly ended an injury-marred season in a positive way.Smyly won his fifth straight decision, Grady Sizemore had a three-run double and the Tampa Bay Rays beat the Miami Marlins 6-4 on Wednesday night.Smyly (5-2) allowed one run, three hits, three walks and had eight strikeouts over six innings in his final start of the season. After losing his first start on Aug. 16 following a three-month absence due to a torn left labrum, the left-hander has gone 5-0 over an eight-start stretch. "I've worked hard, rehabbed, put in the time, and very happy with how I finished the season," Smyly said.Brad Boxberger gave up Dee Gordon's RBI single in the ninth before recording his 40th save.Nick Franklin had a two-out solo homer in the fifth off Jarred Cosart (2-5) before Sizemore put the Rays up 5-1 with his bases-loaded opposite-field double down the left-field line.The Rays loaded the bases on two walks and Evan Longoria's infield single, which came about because an out call at second base was overturned after a Tampa Bay challenge.The announced crowd was 9,431, which was the eighth home turnout under 10,000 this season for the Rays. Tampa Bay has an MLB-low home attendance of 1,186,565.Cosart gave up five runs, five hits and five walks in 4 2/3 innings for the Marlins, who are 0-9 on the road this season against AL teams."Some really good, some not so good," Cosart said.Justin Bour hit a two-out double in the fourth and scored to make it 1-0 on Marcell Ozuna's single. Ozuna has at least one hit in all 12 of his games against Tampa Bay.Asdrubal Cabrera tied it at 1 on a fourth-inning sacrifice fly. He also had an RBI single in the seventh.Tampa Bay center fielder Kevin Kiermaier took an extra-base hit away from Derek Dietrich in the seventh with a leaping catch into the wall. The Marlins got an RBI single from Miguel Rojas later in the inning, cutting the deficit to 5-2."KK takes a lot of pride helping our pitchers in every way possible," Rays manager Kevin Cash said.Miami pulled within 6-3 in the eighth when a run scored on Bour's double play.
