While Stevenson is a proven postseason commodity, UCI freshman Evan Brock proved again he could be a pitcher who will factor in beyond the regular season, which ends today.
Brock pitched into the ninth, allowing six hits, notching a career-high eight strikeouts and earning the victory to improve to 5-4. The right-hander gave up a double and a run-producing triple in the first inning, then settled in.
After Matt Duffy singled with one out in the second inning, Brock retired 20 of the next 21 until giving up back-to-back singles to open the ninth.
Sophomore Nick Hoover came on to retire the side and preserve the win, which clinches the series and further solidifies a berth in one of the 16 four-team NCAA Regionals for the Big West Conference's runner-up (36-19, 16-7 in conference).
Regional pairings will be announced Monday.
"This was his best yet," UCI Coach Mike Gillespie said of Brock's fifth collegiate start, the longest outing of his career. "He walked nobody, so that's a true indicator, and he mixed his pitches really well. I think he was effective with all three pitches."
Stevenson was just part of an offense that was effective for the second straight night. Following a 12-hit effort in a 6-0 win Friday, UCI collected 15 hits against three 49ers pitchers.
Junior Drew Hillman, an Orange Coast College product, went three for five with an RBI, and juniors Jonathan Hurst and Brian Hernandez had two hits apiece.
Hillman and Hurst, who appear to have claimed jobs in an outfield that has been in flux all season, are both five for nine with two RBIs against Long Beach State (23-31, 7-16).
