HAYWARD, Calif. – Head Coach Barbara Pierce started every senior on her roster in Saturday's opening game during "Senior Day" at Pioneer Field. It made the 5-2 and 8-0 victories over UC San Diego that much sweeter with Nikki Foster, Jaynie MacDonald, Lauren Vestal, Brittany Enny, Kelsey LaVaute, Emily Perlich, Alex Vela, and Cassie Vela getting the starting nod.

The most surprising starter was pitching in the circle for the Pioneers. Perlich threw 156 pitches in game two on Friday and was slated to start back-to-back games after throwing an effective 10 innings against the Tritons.

Perlich threw 108 pitches in Saturday's effort as she picked up her third win of the season. She lowered her season earned run average from over five to 3.65 following her "Senior Day" effort with the help of C. Vela catching her final home start.

It was an unconventional route to the win with 16 of the 21 outs recorded coming on fly ball outs. Perlich gave up six hits, including three for extra bases, and issued a walk in the win.

The only thing that matters to the senior is getting the Pioneers a victory in her final appearance on Pioneer Field. Perlich received the offensive lift that lacked yesterday with the help of several seniors, and leadoff hitter Gabby Gonzalez.

MacDonald launched her team leading 13th homer of the season with two outs in the third to give Cal State East Bay a 2-1 lead. She would go on to hit another third inning homer in game two to score the final runs of the day in an 8-0 mercy rule victory in her final game at Pioneer Field.

MacDonald finished 3-for-5 at the plate including two home runs, scored three times, and reached base in 4-of-6 plate appearances. She enters the final weekend of the season two homers shy of the program's single season record (16) and three away from matching the career mark (23).

Enny finished with a base hit in each of her two starts on Saturday. A clutch first inning two-out, two-run single in game two pushed the Pioneer lead to 4-0 before the home side added another four spot in the third.

A. Vela was part of that first inning rally and finished game two with an RBI single and a third inning double. Catcher Ali Cerminara and game two starting pitcher Sierra Clark each singled.

Clark needed just 53 pitches to toss a complete game shutout. She surrendered three singles and struck out two batters in five innings in picking up her 12th victory on the season.

LaVaute provided the game-winning RBI single in the first after three of the opening four batters reached base safely to start the game. UCSD starting pitcher Alexis Edwards was forced to exit after only recording two outs.

She gave up four hits, issued three walks, and threw a wild pitch before being chased from the game. On Friday, Edwards used 123 pitches while throwing nine shutout innings against the Pioneers.

Vestal finished with an RBI and brought home two runs on Friday. In game one she threw out UC San Diego's (24-22, 14-18 CCAA) leadoff hitter Emily Sklencar attempting to turn a single into a double in a 2-1 game.

Foster beat out an infield single in the fifth inning of game one and later hustled around the bases on a Gonzalez double which padded the Pioneer lead to 3-1. She also assisted on the first three plays of game two as all three Triton batters went down grounding out to the East Bay shortstop.

The leadoff hitters from both teams did their job in the opening game with East Bay's Gonzalez going 3-for-4 with a pair of RBI. She drove in a run with a fifth inning double and sixth inning single.

UCSD's Kendall Baker went 3-for-3, but the rest of her teammates combined to go just 3-for-26 (.115). The Tritons did not have an extra base hit following a McKenna Clewett leadoff home run in the seventh inning of the opening game.

Cal State East Bay (25-22, 13-19 CCAA) will finish the 2015 campaign at San Francisco State (11-37, 6-26 CCAA) next weekend. At least one victory in the four game series would clinch back-to-back winning seasons for the first time since 2006.
