SAN LUIS OBISPO, Calif. (Interstat) — West Virginia’s offense erupted for 17 runs on 19 hits Saturday afternoon and evening at Robin Baggett Stadium, overwhelming Cal Poly 17-1 and completing a two-game sweep of the Mustangs.

The Mountaineers (45-15) put the game away early, answering Cal Poly’s first-inning run with a seven-run second inning and never looking back. The Mustangs (39-24) took an initial 1-0 lead in the bottom of the first when Nate Castellon singled, moved to third on Dylan Kordic’s single and scored on Ryan Tayman’s sacrifice fly. But West Virginia responded immediately in the top of the second.

Matthew Graveline led off with a ground-rule double down the right-field line, stole third and then scored on a double steal after Matt Ineich walked and stole second, bringing Graveline home. Brodie Kresser walked, and Ben Lumsden followed with a three-run homer to deep left field, his second of the season, scoring Ineich and Kresser. Tyrus Hall added a solo home run to left-center, his seventh. The inning continued with Armani Guzman hit by a pitch, a stolen base, a walk to Gavin Kelly and a sacrifice bunt. Sean Smith singled to left to drive in Guzman, stole second and later scored on Graveline’s groundout, pushing the lead to 7-1.

West Virginia kept adding on. In the third, Kresser singled, Lumsden grounded out and Hall grounded out, but Guzman launched a two-run homer to right, his first of the season. Kelly doubled and scored on Paul Schoenfeld’s single to right. In the fourth, Kresser singled again and Lumsden hit his second homer of the game, a two-run shot to left, his third of the season. Hall singled and stole second, but Guzman grounded out.

Gavin Kelly led off the fifth with a solo home run down the left-field line, his 17th. Schoenfeld doubled and stole third, and Smith walked. Graveline grounded into a double play that still scored Schoenfeld. In the sixth, Kresser walked, Lumsden singled, and Hall reached on a fielder’s choice. After a pitching change, Guzman singled to left to drive in Kresser. Kelly walked, and Schoenfeld’s groundout brought home Hall. In the seventh, Graveline singled, Ineich singled, and after two strikeouts Graveline stole home again, with Ineich stealing second. Hall walked but Guzman flied out.

Cal Poly’s offense managed only seven hits. After the first-inning run, the Mustangs threatened in the fifth with singles by Dante Vachini and Nate Castellon, but Alejandro Garza grounded out. In the sixth, Kordic doubled with one out, but Tayman grounded out and Cam Hoiland struck out. In the eighth, Kordic singled again, but Tayman struck out. West Virginia used six pitchers: starter Maxx Yehl, David Hagen, Ian Korn and Ben McDougal, who combined to hold Cal Poly to one run on seven hits while striking out 11.

The most pivotal moment came in the top of the second, when West Virginia turned a 1-0 deficit into a six-run lead. Lumsden’s three-run homer and Hall’s solo shot changed the game’s trajectory, and the Mountaineers never allowed Cal Poly back into the contest.

West Virginia continued its winning ways after a 12-2 victory over the Mustangs on Friday. The Mountaineers have won 11 of their last 13 games. Cal Poly lost its second straight after beating UC San Diego and Virginia Tech earlier in the week.
