Frazier went 2 for 4 with a walk, an RBI and two runs scored, ending a four-game hitless streak. Frazier is 7 for 44 in May, with a .474 on-base plus slugging percentage. He had six home runs in April. 

Jack Hannahan will start at third and hit seventh during the game. Frazier should return to the starting lineup Wednesday against the Braves' Mike Minor. Frazier is hitting .239/.318/.451 in 113 at-bats. 

But is that the right move? Maybe. It's not like Frazier's slump has lasted a few games. It's been several weeks. A .148 average and 24 strikeouts in his last 24 games isn't going to instill a lot of confidence in Fantasy owners. 

If you can afford to be patient for a few more weeks, then I say hold onto Frazier. He was due for a market correction after bursting out of the gate, but Frazier's has been a little more extreme because I think he's had a little bad luck in this stretch. He has just a .243 BABIP, which is well below his career .293 mark, per FanGraphs.com. Also, Frazier has just an 11.3 percent line-drive rate through 30 games, which is below his career 20.4 percent mark.

Also, it's worth pointing out Frazier has been terrible on the road this year. He's batting just .122 in 14 away games, as opposed to .316 in 16 home games. Frazier hasn't been great on the road in his career, but he hasn't been this bad of a hitter. In his career, he has a .255 average and .471 slugging percentage on the road.

It seems if these three trends head back toward the norm for Frazier, then we might start to see a more reliable Fantasy option emerge.

"Frazier’s good against lefties and Bruce has struggled against this guy," Baker said, per the Cincinnati Enquirer. "It’s been a struggle this first month with Bruce, period. We need some RBI from Frazier and he’s been pretty good with men on base."

Baker said he isn't sure how long this lineup change will last.

"Things change during the course of a season, because we are in the production business," Baker said. "Sometimes you’ve just got to do things. You wait and wait and wait and sometimes you’ve got to make a change. I don’t know how long this is for."

Frazier entered play Sunday mired in a 3-for-25 slump (.120) in his last eight games, dropping his season average from .305 to .250. However, his 19 RBI rank second on the team behind Brandon Phillips' 22 RBI.

Frazier's sixth-inning shot against Jeff Samardzija proved to be the only run of the game. Frazier finished 1 for 2 with a walk to go with the home run and is hitting .263/.352/.553 on the year.
