The first six innings were fairly silent for both TCU and UT Arlington, with both teams having no more than one run each.

Then, in the seventh inning, everything changed. The Mavericks’ offense exploded—driving in seven runs in the seventh inning—and TCU couldn’t answer with a run of its own.

Those seven runs put a stamp on UT Arlington’s 8-1 win, upsetting No. 2 TCU (21-5, 4-2 Big 12) Tuesday night at Clay Gould Ballpark in Arlington.

Despite the seventh inning fallout, TCU head coach Jim Schlossnagle said he was pleased with how his team played.

“We had a lot of good at-bats,” he said. “We just didn’t string them together, and we didn’t have balls fall in, so this is a great example of, baseball’s a really tough game sometimes.”

Schlossnagle said he didn’t see a need to replace left-handed pitcher Tyler Alexander earlier in the inning, either.

Alexander had struck out the first batter, while the next batter flied out to center field. He only needed one out to end the inning and get the Frogs back on offense.

Then came a single by UT Arlington’s R.J. Williams and another single by Darien McLemore.

With two men on base, a member of TCU’s staff approached Alexander at the mound. It looked as if Alexander’s night was over.

But Scholossnagle said he was still confident that Alexander could get the third out.

“I still liked Tyler’s stuff,” Schlossnagle said. “He had two outs, nobody on, a couple groundball singles. I still felt good about him as a pitcher.”

So, Alexander stayed on the mound. UTA’s Brady Cox then wacked the ball toward right center for a double to send his teammates home.

After Alexander walked another batter, it was time for a change. Brian Trieglaff took over on the mound but struggled to get that final out to end the inning. Runner after runner dashed to home plate, until Trieglaff managed a strikeout to put the inning to an end.

Eight runs is the most TCU has allowed all season in a single game.

UT Arlington (13-14, 4-5 Sun Belt) had not scored more than four runs in each of its last five games. The Mavericks’ struggling offense entered Tuesday’s game on a five-game losing streak. That streak is over now.

The credit did not just belong to the offense, though. UT Arlington went through a series of four pitchers to limit TCU to one run.

The Frogs’ only run came from Connor Wanhanen, who came to bat as Keaton Jones stood on base. When the pitch came, Wanhanen sent the ball into right field for a RBI triple, driving Jones into home plate.

UTA pitcher Jake Wilcox then stepped out of the bullpen to replace Zach Hobbs, who had allowed Wanhanen’s triple. Hobbs efficiently kept the Frogs at bay, not allowing any runs until he was replaced by freshman Daniel James in the seventh inning. James (2-1), who pitched three innings, took credit for the win.

Alexander (1-2) took the loss, ending the Frogs’ four-game winning streak—an upset by a team who entered the game standing four spots from the bottom of their conference.

Schlossnagle said TCU, who will face a series against Texas Tech beginning Thursday, still has respect for UT Arlington.

“We’re not surprised,” he said. “I don’t think our guys had their head in the clouds.”
