Watch Now: How Do The Cardinals Finish The 2020 Season? (2:28)

The Cardinals are finally back in action, but now it's the Reds that are the problem.

It doesn't look like a full-blown outbreak. They had one player test positive Friday, which was enough to cancel Saturday's and Sunday's games against the Pirates. So far, all other relevant persons have tested negative, so the hope is they were able to contain the spread.

Could they turn up another positive test between now and the start of their series at the Royals Tuesday? It's possible. Could MLB decide to cancel that series anyway out of an abundance of caution? It's less likely, but we can't completely rule it out. And then, of course, their four-game series at the Cardinals to close out the week also hangs in the balance, as if that team needed more postponements.

The situation is iffy enough that I'm removing Nick Senzel and Jesse Winker from these sleeper rankings, as much as I'd like to recommend them. You'll want to play it cautiously with your Royals and Cardinals as well, at least until the Reds have been officially cleared.

10 Sleeper hitters for Week 5 (Aug. 17-23)
SD San Diego • #30 • Age: 30
Matchups
@TEX2, TEX2, HOU3
OWNED

He appears to be over his stomach issues finally, having started six of the Padres' past seven games, and so far, his efforts to elevate the ball more have had the desired effect power-wise.
BAL Baltimore • #25 • Age: 25
Matchups
TOR3, BOS4
OWNED

One of the hottest hitters from the past week will benefit from a full slate at Camden Yards and may be more than just a hot-hand play with how much he's elevating and how little he's striking out.
NYM N.Y. Mets • #9 • Age: 27
Matchups
@MIA4, NYY3
OWNED

Even while getting more chances against lefties this year, he's been on base constantly and is making more consistent contact, too. Both the expected stats and this week's matchups suggest even better times are ahead.
BAL Baltimore • #39 • Age: 26
Matchups
TOR3, BOS4
OWNED

The early power display has been impressive, and now he gets a full week at home against some bottom-feeder pitchers, especially in that Red Sox series.
MIA Miami • #24 • Age: 30
Matchups
NYM4, @WAS4
OWNED
43%
So far, he has looked more like the Jesus Aguilar who broke through with 35 homers and 108 RBI two years ago than whatever we saw last year. Here's to more of that in an eight-game week.
TEX Texas • #15 • Age: 25
Matchups
SD2, @SD2, @SEA3

With two doubles and a homer Friday, the power is beginning to pick up for a player who has demonstrated a strong batting average profile so far, and the matchups this week could fuel even more of it.
CHC Chi. Cubs • #8 • Age: 26
Matchups
STL3, CHW3

While he hasn't been playing quite every day, Ian Happ has cut down on his strikeouts even more this year and is killing the ball whenever he's in the lineup. He's looking like he may take a stud turn this year.
NYM N.Y. Mets • #2 • Age: 25
Matchups
@MIA4, NYY3
OWNED
24%
He has been putting the ball in the air more this year, and it's led to big power production so far. There are enough righties on the schedule for him to take advantage of the favorable matchups.
BOS Boston • #99 • Age: 24
Matchups
@NYY1, PHI2, @BAL4
OWNED
67%
He hasn't capitalized on his recent move up the lineup, but the matchups make him worth keeping active for another week, especially since he's missing Aaron Nola in that Phillies series.
OAK Oakland • #8 • Age: 31
Matchups
@ARI2, ARI2, LAA3
OWNED
9%
He has only gotten to play against righties, but fortunately, that's all the Athletics have on the schedule this week. The production, including a newfound aggressiveness on the base paths, has been incredible so far.
