SAN ANTONIO – Mark Schramek’s two-run homer broke a 2-2 tie in the bottom of the seventh inning to lift UTSA (2-4) to a 4-2 win over Arkansas (1-2) Saturday in the second game of a three-game series at Nelson Wolff Municipal Stadium. Klae Boehme (1-0) pitched 2 1/3 innings of scoreless relief to earn the win for the Roadrunners, who won Friday’s series opener 7-6. Arkansas starter Charlie Isaacson (0-1) suffered his second collegiate defeat in Saturday’s game despite yielding just three hits and one earned run with six strikeouts in 6 1/3 innings in his first start since March 21 of last year. The Razorbacks struggled defensively for the second day in a row as UTSA exploited three Razorback errors for two of their four runs and never trailed thanks to a solid outing by starting pitcher Jared Howton. The left-hander received a no-decision but gave up just two runs on eight hits in 6 2/3 innings and held the Hogs scoreless until Tigger Lyles tied the game at 1-1 in the top of the fifth inning with his first collegiate home run. UTSA regained the lead in the bottom of the inning when Jeremy James reached on an error and scored on a wild pitch by Isaacson. The Hogs tied the game again in the top of the sixth when Michael Conner’s sacrifice fly scored Kyle Washburn to tie the game at 2-2. The game remained tied 2-2 until the bottom of the seventh when Justin Brandt – a Fort Smith, Ark., native and former transfer from Westark College – doubled off Isaacson and brought Jared Manatt out of the UA bullpen to face Schramek, who greeted him with the game-winning homer. UA threatened to break the game open early when the Hogs loaded the bases with no outs in the top of the third on a leadoff single by Lyles and a pair of bunt hits by Jeff Hoefler and Scott Crossett, who extended his career-best hitting streak to 15 games. But Crossett got doubled off first base on a line out by Brian Kirby and Washburn’s groundout ended the inning. UTSA will try to complete the three-game sweep Sunday series finale at noon CT. The Razorbacks return to Baum Stadium next weekend to host Long Beach State for a three-game series beginning with Friday’s 3 p.m. CT contest.
