Cincinnati is expected to make another round of promotions, likely on Tuesday, after its Minor League affiliates end their seasons. Price said the "jury's still out" on who exactly will be joining the Reds.
"It may be a game that we split -- start Sampson and have one of the other kids we bring up come in behind him," Price said, also considering Pedro Villarreal, who's pitched well as a long reliever. "There's some options. We'll have a large number of pitchers available to pitch that day."
But Price did point out that it would be left-hander Brandon Finnegan's day to pitch, and he has been stretched out to 88 pitches at Triple-A Louisville. The centerpiece of the Johnny Cueto deal, Finnegan arrived in Kansas City as a dominant reliever but never started in the Majors.
The 22-year-old has struggled as a starter in the Minors this year, going 0-5 with a 5.14 ERA in 15 outings. But as Price was quick to point out Sunday, Finnegan is still a young player -- in fact, he's not even two years removed from pitching for Texas Christian University.
"Being able to isolate him for an inning or two at a time at the big league level has let his stuff play up," Price said. "It's a huge jump. It's a huge change. He's in a time right now of maturing as a starter and getting back to learning how to manage that lineup.
"We've liked the stuff. The stuff has been good. It's just been harnessing it more with a higher percentage of strikes and finding a way to work his way through that lineup."
