ASU baseball hung tight with No. 9 Oklahoma State for the duration of their weekend series in Stillwater but fell short in all three games, getting swept by the Cowboys.
The Sun Devils (24-20) and sophomore starter Brett Lilek struggled Friday night, with Lilek allowing six runs (three earned) in 2 2/3 innings to pick up his third loss of the season.
Sophomore catcher R.J. Ybarra gave the Sun Devils a 3-2 in the top of the third inning with a two-out, two-RBI single to center but the Cowboys (35-13) countered with four of their own in the bottom of the inning, chasing Lilek and recapturing the lead.
The Cowboys added runs in the fourth and fifth innings off sophomore reliever Eric Melbostad and the Sun Devils rallied for two in the seventh inning, but it wasn't enough and the Sun Devils fell 8-5, the team's fourth Friday night loss in their past five tries.
The Sun Devil bullpen spoiled sophomore starter Ryan Kellogg's fourth straight quality Saturday night, losing 6-5 in 11 innings.
Kellogg, who allowed just three runs in six innings, and the Sun Devils took a 5-3 lead into the eighth inning but sophomore relievers Jordan Aboites and Ryan Burr each allowed a run to extend the game to extra innings.
The Cowboys won the game in the 11th inning with a two-out RBI single from sophomore shortstop Donnie Walton off Sun Devil freshman reliever Eder Erives, who picked up his first career loss.
The Sun Devils excelled offensively Sunday afternoon but couldn't hold down the Cowboys offense, losing a 14-12 shootout.
Junior starter Darin Gillies was bounced after just two innings after allowing seven hits and six runs, but the Sun Devils led 11-8 after four innings thanks to a seven-run fourth inning.
The seven-run fourth was capped off by a grand slam from freshman catcher Brian Serven, the first of his young career, but the Sun Devils couldn't hold the lead.
The Cowboys scratched two runs across in the fifth inning then took the lead for good in the sixth inning with three runs and redshirt freshman reliever Nick Diamond picked up his third loss of the season.
The Sun Devils return to action May 9 for a weekend series with No. 10 Oregon at Packard Stadium.
