T.J. McFarland hasn't had the easiest of transitions to Triple-A ball, but he showed Sunday just what he's capable of at the Minors' highest level.

The Indians' No. 20 prospect allowed three hits and a walk over eight-plus innings as the Columbus Clippers blanked the Norfolk Tides, 1-0.

It was his first scoreless start since tossing a complete-game shutout June 24, a stretch covering six starts. In July, McFarland (5-5) was 2-4 with a 7.18 ERA over six outings. That included his two previous starts, both losses, during which he allowed a combined 11 earned runs in 10 innings.

It was back to basics in his first August outing.

"I've kind of had a roller-coaster year so far here with a lot of ups and downs," McFarland said. "But I kind of realized that all the good ones came when I was throwing strikes, attacking hitters and being confident with all of my pitches. If I'm pounding the zone, I'll let them hit my sinker, changeup or slider, but it'll lead to some quick outs like I had tonight."

The Illinois native was at his best in the latter innings Sunday. After walking Bill Hall with two outs in the fourth, he retired 16 straight Tides hitters. Soon after McFarland's streak began, Matt LaPorta drove in the game's only run with a sacrifice fly in the fifth. That slim 1-0 lead was one of the biggest driving factors for the starter's performance, he said.

"I realized we weren't scoring a whole lot of runs, and that it was going to be one of those pitchers' duels," McFarland said. "So I knew I had to bear down and make sure not to give back that lead. Every guy you put on base, every run you allow counts big time in games like that."

The southpaw was pulled after allowing an opening single to Xavier Avery in the ninth, finishing with 91 pitches, 59 for strikes. Frank Hermann got the remaining three outs to preserve the shutout and earn his seventh save for the Clippers.

McFarland earned just his second win in his last six starts with the other four resulting in losses.

In his 12 starts with the Clippers, the sinkerballer owns a 5.05 ERA and a 1.47 WHIP. That contrasts with the 2.69 and 1.21 marks he put up in 10 starts for Double-A Akron to start the year, and that dichotomy hasn't been lost on the hurler.

"The biggest part is that [Triple-A] hitters are smarter," he said. "In Double-A, I could get away with throwing a sinker or slider in the dirt, and they'd swing at it. Here, they're less likely to do that. Plus, through the second and third times in the order, they pick up more about you, so you have to be more creative. That's still something I'm trying to figure out personally."

But with a course-correcting start like Sunday's under his belt, McFarland has a little more confidence that he can finish his first International League campaign on perhaps a higher note than he believed possible 24 hours ago.

"It's just the confidence that I took away really," he said. "If I do pound the strike zone, I can get the results and can give the team a win. It's just nice to know my stuff can play here."
