Kirby (2-2) finally came out on the right end of a low-scoring game, tossing a five-hit shutout with one walk and four strikeouts. The Scots had just one baserunner reach second base, Will Lindsey in the first inning, though the visitors had one hitter reach in five of the seven innings. Kirby lowered his ERA to 0.26 in 35.0 innings this season.
Talan Roepcke (5-2) was the tough-luck loser for the Scots, giving up one run on five hits. The lefthander walked two and struck out five.
Mandarino (4-1) was just as impressive in the second game, allowing a single hit, which went all of about 100 feet, with two walks and five strikeouts. Lyon had runners on second and third in the third, but the righthander struck out two batters to end the inning. The only other runner in the game for the Scots was a walk in the sixth.
Brandon Haller (4-2) took the loss for the Scots, giving up one run on two hits with two walks and three strikeouts.
In the opener neither team had many scoring opportunities. In the top of the first Lindsey walked with two outs and Bryan Lynn singled, but Colby Rogers lined out to left to end the inning.
In the bottom of the inning Lind was hit with two outs and moved to third on Josh McGees two-out double, but Brodie Ross flied out to end the threat.
McGee doubled again in the fourth, this time to leadoff, and pinch-runner Chris Del Bianco stole third, but Ross flied out, William Henderson struck out and Heath Holliday lined out, stranding the runner at third.
The Bulldogs finally got on the board in the fifth inning after freshman Tyler Alford collected his first collegiate hit with a one-out single. Critchelow stole second and scored on a two-out double off the centerfield wall by Lind.
In the second game Lind singled in the first and two batters later Mandarino walked, but Daniel Harrison struck out to end the inning.
Roger Glaude beat out an infield single and Nathan Gutierrez walked to leadoff the Lyon third, but Mandarino worked out of the jam with a pair of strikeouts.
Lind put the Bulldogs on the board in the second game as well with a towering solo homer to right, across Spring Street, with two outs in the third.
CU had a chance to add to the lead in the sixth, loading the bases after Cory Urquhart and McGee were hit and Mandarino walked, but Harrison grounded sharply into a doubleplay to end the threat.
The two teams conclude the series Sunday at 1 p.m. The Bulldogs host Missouri Baptist at Veterans Field in Lebanon on Tuesday at 6 p.m. and take on the Spartans again Wednesday at home at 2 p.m.
