The second occurs in the Grapefruit League, where manager Clint Hurdle and pitching coach Ray Searage size up hopefuls against stiffer competition.
"We try to give guys trying to make the club a more competitive lineup to pitch against," Hurdle explained.
Adam Wilk stepped into that bubble Sunday without having it burst, starting against the Phillies and blanking them for three innings on two hits, setting up the Bucs' 5-0 whitewash.
"Just working on keeping the ball down, getting good movement on the ball, staying ahead," Wilk said. "I'm not a guy that blows it in the mid-90s, so I've got to keep the ball down. I have my pitches working, and it's going well right now."
Wilk has pitched 10 innings and allowed one run and seven hits with one walk and six strikeouts.
"He was very efficient again today," Hurdle said. "He's shown command of the fastball, used his cutter extremely well, and it was a good go-to pitch versus left-handed hitters. And he threw some good changeups and curveballs to right-handers. He's kept the ball down."
Wilk is also keeping his nose down, to the grindstone, as it were. He won't concern himself with trying to figure out where he stands in the pitching competition.
"Whatever happens will be nothing new to me," said the 26-year-old onetime Detroit prospect. "I'll just go out and pitch and prepare myself, and let the manager or whoever has that decision, make it."
