BAKERSFIELD, Calif. — One bad inning by the CSUB defense and a solid pitching performance from UC Riverside’s Matt Andriese gave the Highlanders an early lead to build on in a 6-1 loss for the Roadrunner baseball team Friday at Hardt Field.

UC Riverside (20-8) took advantage a pair of Bakersfield errors, along with three walks to score three runs in the top of the second. The Highlanders later added one in the seventh and two in the ninth to seal their 20th win of the season.

In the second, Robert Brantly and Daniel Pellegrino led things off with back-to-back walks. Justin Schultz then reached on an intended sacrifice bunt, but Brantly safely reached third after a CSUB error on the play. Bryan Horst followed with another fielder’s choice, but the Roadrunners once again failed to get an out, this time on an error by shortstop Kyle Richardson. Brantly crossed home plate on Horst’s hit for a 1-0 lead. Trevor Hairgrove walked to send Pellegrino home and a sacrifice fly by Carl Uhl put UCR ahead 3-0.

CSUB starter Jonathan Montoya (3-3) found his mark after the second inning, retiring eight consecutive batters before giving up a double in the top of the fifth. He quickly retired the Highlanders’ next batter on a fly out to center field, then kept UCR off the bases on the sixth inning as well.

UC Riverside’s solo run in the seventh came courtesy of a RBI-single by Tony Nix while their final two runs came from a Hairgrove RBI-double and a Nix RBI-single.

After pitching a complete game victory over Fresno State  in his last appearance, Montoya was solid in the loss Friday, striking out four, walking five and scattering five hits for four runs, but just one earned, in 7 2/3 innings. Spenser Messmore pitched the final 1.1 innings, giving up three hits for two runs.

Bakersfield’s offense was held silent by right-hander Andriese (3-1). The freshman struck out five, walked one and scattered three hits for one run in eight complete innings.

The Roadrunners’ lone run came in the bottom of the eighth when Joey Mills tripled to left center, then scored on a Brandon Boren sacrifice fly to right.

Mills, Richard Escalera and Jason Kudlock recorded the Roadrunners only hits of the day.

CSUB (7-23) and the Highlanders conclude their three-game series Saturday in a 1 p.m. start at Hardt Field.
