The Commodores added one more before the end of the inning when freshman shortstop Dominic De La Osa's single brought home Matt Buschmann, who had been inserted as a pinch-runner for Hernandez.
Greg Del George, a redshirt freshman, got his first career hit — a solo home run to right field — with one out in the bottom of the seventh when he replaced Feinberg. Vanderbilt scored its final run in the bottom of the eighth.
Senior Jeff Sues (five strikeouts) started for the Commodores and took the loss. He pitched three innings before he was relieved by sophomore Stephen Shao (four strikeouts) with none out in the fourth. Shao pitched two innings then gave way to red-shirt freshman Ty Davis, (two strikeouts) who also pitched two innings. Redshirt freshman Cody Crowell pitched the final two innings and did not allow a run.
Vanderbilt's staff now has struck out 10 or more in 10 of 14 games this season.
Baylor, 10-7 and ranked 18th, broke open the contest with a six-run fourth inning that included four straight extra-base hits, a two-run triple by Chase Gerdes, an RBI double by Michael Griffin, a double by Kyle Reynolds and a two-RBI double by Josh Ford.
The Bears went ahead to stay in the first inning when Gerdes led off with a walk and Griffin followed with a home run. Vanderbilt's first two batters, left fielder Aaron Garza and Feinberg, singled in the bottom of the first, but Baylor starter Corey VanAllen got out of the inning without a run allowed. The Bears then added two more in the third on Reid Brees' single. They also scored five runs in the sixth and one in the seventh.
VanAllen earned the win as he pitched six innings, allowed seven hits and three runs with three strikeouts and three walks.
The final game of the series is scheduled for 1 p.m. Sunday at Hawkins Field.
