The Tacoma Rainiers clinched the 2010 Pacific Coast League Pacific Conference Championship after defeating Sacramento 4-1 at Safeco Field on Sunday in the fifth and final game of their best-of-five series with the River Cats.

The conference title is the Rainiers first since 2005, when that Tacoma squad also defeated Sacramento in the fifth game and final game of the series en route to the PCL Championship Series.

Tacoma had to put together a minor rally for the win after River Cats designated hitter Chris Cater gave Sacramento the lead with a solo home run in the top of the fifth. Rainiers infielder Matt Mangini evened the game at 1-1 with a single to left field that scored Dustin Ackley sixth inning.

A mishap by Sacramento first baseman Tommy Everidge provided the go-ahead run for the Rainiers in the bottom of the seventh. After designated Mike Wilson was ruled safe at second on an attempted double play, Everidge tossed the ball into the stands with only two outs in the frame. The play was ruled a two-base error, scoring Wilson from second base and giving Tacoma a 2-1 advantage.

Mangini added some insurance in the next inning after belting a two-run home run with Dustin Ackley aboard in the eighth.

The third baseman Mangini proved to be the top performer for the Rainiers in the conference-clinching win after going 3-for-4 with a double, a home run and accounting for three of the Rainiers four runs.

Tacoma starter Ryan Feierabend turned in the strongest performance of his 2010 campaign to earn the win for the Rainiers. The left-hander allowed just one run to the River Cats on two hits with four strikeouts and no walks over eight-innings of work. The loss went to Sacramento reliever Lenny DiNardo after the left-hander surrendered three runs, two earned, on two hits over 1 2/3 innings, while fanning one.

Tacoma will now go on to face the American Conference champion Memphis Redbirds in the best-of-five Pacific Coast League Championship Series. The entirety of the series will played at AutoZone Park in Memphis due to the $30 million dollar offseason renovations at Cheney Stadium.

The first game of the series is scheduled to be played on Tuesday, September 14, followed by Game 2 on Wednesday, September 15. The series will resume for Game 3 on Friday, September 17, with Games 4 and 5 slated for Saturday, September 18 and Sunday, September 19.
