The Pirates were lifeless at 12-26 when they fired manager Derek Sheldon, and since then, the Pirates have been playing much better, going 26-24 under replacement Don Kelly. The Pirates have won six straight, and they're pitching great with 31 scoreless innings active and hitting .317 during the streak. They swept the Mets, and then they shut out the Cardinals in all three games. The combined score in the six-game winning streak is 43 to 4. The Mariners have looked very ordinary in their last three games, scoring no more than three runs in losing two out of three. Bryan Woo is a terrific starter, but the reality is the Mariners have lost three of his last five starts. Pirates to win.
