Now they'd like to see him do it in the bigs.
Tomlin will be called up from Triple-A Columbus on Tuesday to start against CC Sabathia and the Yankees at Progressive Field.
Manager Manny Acta is looking forward to the Major League debut of Tomlin, a 25-year-old right-hander who has forced his way onto the Tribe's radar.
"He's worked himself to this point," Acta said of Tomlin, a 19th-round selection out of Texas Tech University in the 2006 First-Year Player Draft. "He doesn't get attention because of his velocity, but if you can change speeds consistently, you have a chance."
Tomlin went 8-4 with a 2.68 ERA through 20 appearances (17 starts) for the Clippers this season.
"The numbers speak for themselves," Acta said. "But they need to be challenged, and this is the next step. Is he going to be facing better hitters here? Yes. But he also knows how to pitch."
