Reynolds entered the game mired in a 4-for-44 (.091) slump, causing manager Ron Roenicke to split first base between rookie Matt Clark and usual catcher Jonathan Lucroy in recent days.
"We know he's a streaky guy; we know that he needs to be out there playing to get it back," Roenicke told the Milwaukee Journal Sentinel Saturday. "We're in a situation where we have to make some decisions and try to play the hottest guy. That's what I've been doing."
After yielding the spot to catcher Jonathan Lucroy the previous two days,
Clark, 27, spent last season in Japan before returning to hit .304 with 26 homers and a .924 OPS in 414 at-bats between Double- and Triple-A this year. Manager Ron Roenicke told MLB.com he'll continue to find at-bats for him as long as he continues to produce.
"That's why we brought him up here, was with the idea that if the matchups were good and he did well, I'd be able to put him back out there," Roenicke said prior to Sunday's game. "With him continuing to swing the bat well, he's going to play a little bit more."
