The Tigers win their third game in a row and now sit alone in second place at 5-2 in SCIAC.
Walsh drew a red card, assisted on a goal and scored two more of his own for a big day. He is now tied for the lead among SCIAC goal scorers with five goals on the season.
Midway through the first half, Walsh gave the Tigers a real spark by drawing a red card on Whittier goalkeeper Nathan Armas and forcing the Poets to play a man down for the majority of the game. Walsh got behind the defense and went to touch the ball around a charging Armas, who took out his legs at the edge of the box on an almost sure scoring opportunity, prompting the decision from the referee.
Oxy's Ryan Wilson drew another important foul, this time in the box, in the 68th minute. Walsh stepped up to take the penalty and drilled it into the upper-v.
Walsh's second goal came in the 85th minute on an easy pass past the keeper.
Rosso, who has four goals and five assists on the season, stole the ball from the Whittier defense and easily rolled a shot into the corner of the net in the 51st minute to give Oxy a 2-0 lead.
Luis Espitia scored the Poets only goal in the 59th minute.
In his first game back from injury, Tod Kawada created some good offensive opportunities for the Tigers. He had a volley that missed high and wide and also a good cross to Matthew Labrie that was on the frame, but saved nicely by William Allgeier.
The Tigers are back in action on Wednesday at Chapman at 4 p.m. in the first of a three-game road trip.Follow Oxy Athletics on Twitter Sign Up for Newsletters Watch on Youtube Follow us on Instagram
