@KC5, @NYY3

His breakout season was interrupted by a hand injury, but he's off the IL and will be treated to the most favorable hitter schedule of any team this week.
Hunter Renfroe RF
KC Kansas City • #16 • Age: 32

ATL3, WAS3

He eventually emerged as a must-start player after a slow start last year and may be tracking that way again, having homered seven times in his past 13 games.
Yuli Gurriel 1B
ATL Atlanta • #10 • Age: 39

at BOS, vs. TEX

The defending AL batting champ caught fire over the weekend and is a good bet to keep it going with the Astros boasting the fifth-best matchups this week.

The Cardinals have shown a commitment to playing the rookie masher, starting him in every game since his call-up, and he has repaid them by, well, mashing. The Pirates series is reason enough to keep him active.
Ian Happ LF
CHC Chi. Cubs • #8 • Age: 29

Matchups

PIT3, ARI4

He continues to be on the fringes of mixed-league consideration but is making enough positive contributions to justify the nod in a week when the Cubs have the second-best hitter matchups.
Alek Thomas CF
ARI Arizona • #5 • Age: 24

@LAD4, @CHC4

The recent call-up appears up to the challenge so far and gets to enjoy an eight-game slate this week. Even though he bats left-handed, he crushed lefties to the tune of a .362 batting average and 1.073 OPS in the minors last year, so the three on tap may actually play to his advantage.
Max Kepler RF
MIN Minnesota • #26 • Age: 31

Matchups

@OAK3, @KC3

Rostered

He's run hot and cold this season but seems to be picking it up again with four hits over the weekend. It's enough reason for hope against two bottom-feeder pitching staffs this week.
Darin Ruf DH
MIL Milwaukee • #25 • Age: 37

@COL3, SD3

Rostered

His move to full-time duty hasn't yet paid off as hoped, but he's heating up, having hit safely in eight of his past nine games. He'll begin Week 7 at Coors Field.
Patrick Wisdom RF
CHC Chi. Cubs • #16 • Age: 32

PIT3, ARI4

He may be inconsistent, but the power output has continued in his sophomore season. You'd expect him to be at his best against pitchers like Bryse Wilson, J.T. Brubaker and Humberto Castellanos.
A.J. Pollock LF
SF San Francisco • #16 • Age: 36

Matchups

@KC5, @NYY3

Rostered

He's been a non-factor after having an .892 OPS last year, but hopefully the most favorable hitter slate is enough to get him going. He's looking at five games against Royals mush as part of an eight-game slate overall.
