Not that you'd sit just any pitcher, of course, but if you're looking to stream with a spot or two, you've come to the right place. Scott White has 10 recommendations for the upcoming scoring period, all rostered in less 80 percent of CBS Sports leagues. Most likely, they're the best you'll find off the waiver wire.

Sleeper pitchers for Week 4 (April 15-21)
Jack Flaherty SP
DET Detroit • #9 • Age: 28

Matchup

at MIN

Rostered

78%
The work Jack Flaherty has put in with the Tigers coaching staff is apparent, with his slider grading out as one of the most effective pitches in baseball so far this season. He's pretty close to must-start against the Twins, who entered Sunday with the fifth-lowest OPS of any team.
Nick Lodolo SP
CIN Cincinnati • #40 • Age: 26

Matchup

vs. LAA

Rostered

74%
Nick Lodolo's return from nearly a year-long absence for a leg injury couldn't have gone any better Saturday as he struck out 10 while allowing just one hit in 5 2/3 innings. Granted, he was facing the White Sox, but even against the Angels this week, I'd trust his sweeping curveball to rule the day.
Luis Gil SP
NYY N.Y. Yankees • #81 • Age: 25

Matchups

at TOR, vs. TB

Rostered

63%
Though Luis Gil has yet to go the minimum five innings required for a win, the strikeouts have been something to behold, his high-90s fastball bolstered by a new changeup. He gets two chances to secure that elusive win this week and may pick up 15 strikeouts in the process.
Garrett Whitlock SP
BOS Boston • #22 • Age: 27

Matchups

vs. CLE, at PIT

Rostered

63%
Garrett Whitlock has broadened his arsenal this season, and the results through three starts have been encouraging. The Pirates and Guardians lineups have overperformed so far and still rate as favorable matchups for him.
Cristopher Sanchez SP
PHI Philadelphia • #61 • Age: 27

Matchup

vs. COL

Rostered

78%
For all the talk of increased velocity, Cristopher Sanchez has been hit-or-miss so far, but you can expect him to be at his best this week with the Rockies coming to town. The Rockies are always a mess offensively when they're away from Coors Field.
Ranger Suarez SP
PHI Philadelphia • #55 • Age: 28

Matchup

vs. COL

Rostered

61%
Ranger Suarez will also benefit from the Rockies on the road this week, and he's off to a fantastic start, exhibiting better command than we've seen from him the past two years along with a much improved ground-ball rate.
Michael Wacha SP
KC Kansas City • #52 • Age: 32

Matchup

at CHW

Rostered

75%
Michael Wacha has been a model of stability in recent years, and you can't ask for a better matchup than the White Sox right now, what with Luis Robert and Eloy Jimenez both being on the IL.
Seth Lugo SP
KC Kansas City • #67 • Age: 34

Matchups

at CHW, vs. BAL

Rostered

68%
Seth Lugo has delivered three quality starts already, but the total lack of whiffs is a little concerning. That's my reasoning for ranking him behind Michael Wacha even though Lugo is the one in line for two starts, including one against that decimated White Sox lineup.
Martin Perez SP
PIT Pittsburgh • #54 • Age: 33

Matchups

at NYM, vs. BOS

Rostered

42%
The way Martin Perez has started out this season is reminiscent of 2022, which is the one time he was a genuine standout in Fantasy. It's reasonable to be skeptical, but with him lining up for two starts this week (against the Mets and Red Sox), he's at least worth using as a volume play in points leagues.
Jon Gray SP
TEX Texas • #22 • Age: 32

Matchups

at DET, at ATL

Rostered

74%
Jon Gray's one good start so far was against an Athletics lineup that would make any pitcher look like an ace, but it nonetheless has him riding high heading into a two-start week. If his slider continues to play up against the Tigers lineup, he could be in for similar results, though the Braves matchup to end the week risks undoing any gains there.
