SAN ANTONIO — Freshman right-hander Jordan Pacheco held No. 1 Baylor to just one run on seven hits while striking out a career-high five in 5.1 innings and UTSA ended the Bears' 24-game winning streak with a 4-1 victory on Tuesday night in front of a season-high 1,151 fans at Wolff Stadium.
The win was the first in UTSA Athletics history against a national top-ranked squad and the baseball program's first in six tries, as the Roadrunners (18-23) previously lost to then-No. 1 Texas in 1993, 2003, '04, '05 and '10.
"I thought we played extremely well," 12th-year head coach Sherman Corbett said after the victory. "We had to get off to a good start and did that tonight. Daniel Rockett gave us a big hit for a multiple-run lead in the first and we did enough to hold on to it."
Pacheco (1-2), who only walked one, picked up the first win of career in the 85-pitch performance. Junior righty Clint Sharp surrendered only one hit and fanned three in 2.2 scoreless innings out of the bullpen, while sophomore Matt Sims struck out two in the ninth for his sixth save of the spring.
"Jordan threw an outstanding game," Corbett said. "Clint and Matt a great job, too. We pitched down in the zone and used both sides of the plate. They did a great job against a very good team."
UTSA drew first blood with a three-run first and never looked back in its first-ever home game against a No. 1 team.
Back-to-back one-out walks to freshman Justin Anderson and senior Casey Selsor set the table for junior Ryan Dalton, whose single through the left side of the infield brought Anderson across the plate for the evening's first run. After Selsor and Dalton executed a double steal, Baylor starter Austin Stone whiffed senior Matthew James for the second out of the the frame. Junior Daniel Rockett followed with a two-run base hit up the middle, which was more than enough for Pacheco in the finale of the Birds' eight-game home stand.
The Bears (35-8) scored their lone run in the fourth when Cal Towey's two-out double plated Logan Vick, but that was all they got the rest of the way.
UTSA tacked on an insurance run in the sixth when sophomore RJ Perucki's two-bagger down the left-field line with one down brought Rockett plateward.
Stone (2-1) allowed all four runs on seven hits, walked three and struck out four in his 5.1 frames of work.
Perucki and Rockett led the Roadrunners' eight-hit attack with two knocks apiece, while Vick paced Baylor by going 3-for-3 with a walk and stolen base.
The Bears, who took over the top spot in the national ranking for the first time in program history on Monday, lost for the first time since dropping a 5-4 decision at UT Arlington on March 13. The Mavericks rallied for three runs in the ninth for the team's lone blemish in the its last 27 games entering tonight.
UTSA now has won three of the last six games in the series dating back to the 2008 campaign and all those victories have come with Baylor holding a national ranking.
The Birds will return to action on Friday night when they begin a four-game road trip at Central Arkansas (16-21, 10-11 SLC). First pitch in the three-game Southland Conference series is scheduled for 6 p.m. at Bear Stadium.
