The surging Seattle Mariners look to improve their playoff position when they visit the Detroit Tigers on Friday to begin a key three-game series. The Mariners have won four consecutive contests and eight of nine, moving within one-half game of Detroit for the second American League wild-card spot. Robinson Cano (.329 average) and Kyle Seager (73 RBIs) lead Seattle while the Tigers have won five straight at home and trail first-place Kansas City by one-half game in the AL Central.Detroit's Miguel Cabrera has not matched his MVP numbers of the last two seasons, but is still second in the AL in hits with 155 - 10 more than Cano. Rick Porcello tries to equal his career high with a 14th victory and opposes Seattle's unbeaten left-hander James Paxton, who has limited opponents to a .200 average in four starts this season. Porcello will have to deal with Kendrys Morales, who went 5-for-12 with two homers in the last three games.TV: 7:08 p.m. ET; MLB Network, ROOT (Seattle), FSN DetroitPITCHING MATCHUP: Mariners LH James Paxton (2-0, 2.38 ERA) vs. Tigers RH Rick Porcello (13-7, 3.11)Paxton has allowed three runs and 10 hits in 10 2/3 innings over two starts without a decision since returning from the disabled list.
