"It's hard to go into a season when any of the guys, whether it's a regular or not, if [a hitter] is not swinging the bat or a pitcher's not throwing the ball well, it's hard to go into a season figuring that when the lights go on that all of a sudden they're going to completely turn this around. Usually it doesn't happen that way."
Roenicke had been asked about shaky results for relievers Neal Cotts and Brandon Kintzler, and was also probed about a lack of offensive production for bench candidate Luis Jimenez.
Entering Tuesday, Jimenez was batting .167 in 36 Cactus League at-bats, tied with Matt Clark for the most at-bats on the team.
"He's got to swing the bat some, sure," Roenicke said. "Because if he's going to be the guy at third base to pick up [starter Aramis Ramirez], there's going to be at-bats there. So whoever that person is needs to swing the bat well."
Of the relievers, Roenicke said, "Whether it's just confidence or whether their stuff isn't the same, that's tough to say. But we need to see more out of them."
Kintzler has made 135 appearances for the Brewers over the past two seasons, and he avoided arbitration with a one-year, $1.075 million contract. Cotts signed a one-year, $3 million contract at the end of January.
Both Cotts and Kintzler pitched Monday against the Rockies. Cotts retired the first two batters he faced in the seventh inning, then went walk, double, single, walk before being removed. Kintzler took over and walked the first man he faced before escaping further damage in the seventh, but he surrendered a triple and a two-run homer leading off the eighth.
Kintzler's ERA is 7.11 in six Cactus League outings. Cotts' ERA in seven games is 10.13, and he's walked six batters in 5 1/3 innings while seeing opposing hitters bat .462.
"The last two have been better than the previous times out there. A lot better," said Cotts, who made a mechanical adjustment last week. "I know the results [Monday] weren't very good, as far as getting the first two outs quickly and then struggling to get the third. The ball is coming out better. … I'm not happy. I wasn't happy not getting through the inning yesterday after getting two quick outs. If I was satisfied with that, I shouldn't be here anymore."
