Mariners vs Rangers Prediction 

Seattle was able to get the dramatic win in game one of this series and they have won three of their last four games. The Mariners have really struggled to score runs this season, but they have scored at least four runs in four of their last five games. Texas has lost three of their last four games and their pitching staff has allowed 22 runs in those three losses. The Rangers are starting Rocker in this game, who has allowed seven earned runs and 13 hits over 8.0 innings of work, but did look better last time out. Seattle is starting Woo, who has allowed five earned runs and eight hits over 12.0 innings of work. Seattle seems to be heating up at the plate and they have the pitching advantage, so I like them to get the win.
