The matchups for Week 10 (Sept. 21-27) seem fairly straightforward — a welcome bit of calm to close out a season of chaos.

But there may yet be some chaos still. As things stand, the Cardinals and Tigers are scheduled to play only 58 games. Should the two missing games become relevant for playoff seeding, chances are those two teams would face off for a doubleheader Sept. 28, the day after the season is supposed to end.

Would those games count in your league? Should they count in your league? In premium leagues where you have control of such things, it's something yo should straighten out now. I'd personally be inclined to count them since they would in fact be regular season games, but someone who doesn't have any Cardinals or Tigers might disagree. The former would go from having eight games to 10 in such a scenario while the latter would go from having six games to eight.

With that said, here are my top 10 sleeper hitters for Week 10, all rostered in less than 75 percent of CBS Sports leagues.

10 Sleeper hitters for Week 10 (Sept. 21-27)
Clint Frazier RF
CHW Chi. White Sox • #15 • Age: 29

Matchups

@TOR4, MIA3

ROSTERED

52%
Manager Aaron Boone has confirmed he'll keep Clint Frazier in the lineup even with Giancarlo Stanton and Aaron Judge back, and with his newfound plate discipline and steady power production, why wouldn't you do the same?
Brandon Belt DH
TOR Toronto • #13 • Age: 36

Matchups

COL4, SD4

ROSTERED

39%
Though he has slowed down recently, he still has an OPS near 1.000 for the year. This week, he has seven games vs. righties, against whom he's done all his damage, and eight at home, where he's batting .400 with a 1.311 OPS.
Ryan Mountcastle 1B
BAL Baltimore • #6 • Age: 27

Matchups

@BOS3, @TOR3

ROSTERED

63%
The rookie continues to show off his hitting prowess, and these matchups aren't the sort that are going to slow him down, especially since he's missing Hyun-Jin Ryu in that Blue Jays series.
Alec Bohm 3B
PHI Philadelphia • #28 • Age: 27

Matchups

@WAS4, @TB3

ROSTERED

59%
Another rookie whose hitting hasn't gotten its due, Alec Bohm has gone hittless just once in his past 12 games, collecting seven extra-base hits during that stretch.
Ryan Braun RF
MIL Milwaukee • #8 • Age: 40

Matchups

@CIN3, @STL3, STL2

ROSTERED

48%
Realistically, he figures to start only six or seven of the Brewers' eight games, but the underlying numbers look studly and he's hot right now, batting .389 (14 for 36) with five homers in his past 12 games.
Adam Duvall LF
ATL Atlanta • #14 • Age: 35

Matchups

MIA4, BOS3

ROSTERED

67%
Adam Duvall hasn't been doing much in between all the home runs, but he continues to hit them, making it difficult to bet against him in a seven-game week that concludes against the miserable Red Sox pitching staff.
Jeimer Candelario 3B
CIN Cincinnati • #3 • Age: 30

Matchups

@MIN2, @KC4

ROSTERED

63%
With a revamped approach at the plate, he looks like a legitimate source of batting average now, and while he did cool off against the Indians pitching staff over the weekend, it should be a different story with his matchups this week.
Chris Taylor LF
LAD L.A. Dodgers • #3 • Age: 33

Matchups

OAK3, LAA3

ROSTERED

44%
Though he has bounced all around the diamond, Chris Taylor has emerged as an everyday player for the Dodgers, reaching base at a high rate while contributing a little power and speed. The triple eligibility makes him especially usable in a week with solid matchups.
Jason Heyward RF
LAD L.A. Dodgers • #23 • Age: 34

Matchups

@PIT4, @CHW3

ROSTERED

28%
He has been striking out less than ever and hitting more line drives than ever, leading Statcast to peg him as a .325 (xBA) hitter this year. With seven games on the road (where he's batting .358 with a 1.236 OPS) and six against righties (.337, 1.041), the splits are well in his favor this week.
Bobby Dalbec 1B
BOS Boston • #29 • Age: 28

Matchups

BAL3, @ATL3

ROSTERED

30%
The all-or-nothing hitter has predictably struggled with less-than-favorable matchups in Week 9, but he could help you make up ground in home runs this upcoming week given how bad the Orioles and Braves rotations are.
