Below are teams to consider stacking for Friday’s 15-game slate. Remember that two- or three-man stacks are perfectly acceptable to use in cash games as well as GPPs, and larger team stacks should be reserved for GPPs.

Los Angeles Angels

There’s no game in Colorado tonight (hallelujah), but many of the other favorable hitter’s parks will see action like Texas, Arizona, Boston and Cleveland. Conditions in Texas tonight will very much favor hitters as it will be a warm 85 degrees at game time with a slate-low air density index of 58 (the less dense the air, the farther the ball travels).

Nick Martinez will be making his second start of the season for the Rangers. In his career, Martinez has just over 300 innings pitched with a 4.37 ERA (5.16 SIERA). Martinez has an essentially even flyball-to-groundball ratio, and he has allowed 1.22 HR/9 for his career with a slightly higher HR/9 at home. 

Mike Trout is quite obviously in play, and the second-best option would be C.J. Cron if he ends up being in the lineup. Cron ranks second among current Angels in wRC+ vs. RHP since the beginning of last season, and he is 6-for-12 in his career against Martinez with two home runs. Stacks are obviously dependent on what the starting lineup looks like, but below are a few potential Angels stacks.

Two-man: Kole Calhoun, Mike Trout

Three-man: Mike Trout, Albert Pujols, C.J. Cron

Four-man: Kole Calhoun, Mike Trout, Albert Pujols, C.J. Cron

Arizona Diamondbacks

Until Arizona starts using the humidor, their park remains a very favorable park for hitters. Tonight they’ll get left-hander Kyle Freeland who is admittedly a bit scary simply because he keeps the ball on the ground at a high rate and has largely kept the ball in the park through four major league starts. But the D’Backs hit lefties well with the 10th best ISO vs. LHP so far after posting the fifth best wOBA vs. LHP last season.

Arizona has two right-handers with excellent career numbers vs. LHP, Paul Goldschmidt (.432 wOBA) and Yasmany Tomas (.391 wOBA). A.J. Pollock and Chris Iannetta also have good career numbers against LHP with wOBAs of .371 and .365, respectively. And then there’s Chris Owings who had a .348 wOBA vs. LHP last year, and Owings has been hot to start the season with a .391 wOBA and four home runs.

Two-man: Paul Goldschmidt, Yasmany Tomas

Three-man: Chris Owings, Paul Goldschmidt, Yasmany Tomas

Four-man: A.J. Pollock, Chris Owings, Paul Goldschmidt, Yasmany Tomas

Colorado Rockies

On the other side of the game in Arizona, the Rockies are also worth considering given their career numbers against Arizona’s starter, Robbie Ray. Active Rockies have a combined 104 PA against Ray and a combined .440 wOBA. Vegas has the D’Backs with the second highest implied total of the night but only has the Rocks with the 18th highest implied total. That means the Rockies could be a bit of an under-the-radar stack option even though they’re away from Coors.

Despite not having the platoon advantage against Ray, Charlie Blackmon has owned him going 11-for-19 with two home runs in his career against Ray. And then you have Colorado’s right-handers with pop as Nolan Arenado, Mark Reynolds and Trevor Story all have career ISOs north of .200 against lefties. DJ Lemahieu also owned lefties last year with a wOBA of .397 against them.

Two-man: DJ Lemahieu, Nolan Arenado

Three-man: Charlie Blackmon, DJ Lemahieu, Nolan Arenado

Five-man: Charlie Blackmon, DJ Lemahieu, Nolan Arenado, Mark Reynolds, Trevor Story

St. Louis Cardinals

Tonight the Cards will face Tim Adelman who leans heavy to the flyball end of the spectrum with a career flyball rate of 47.4 percent. Adelman has fly ball tendencies against hitters of either handedness with a very high fly ball rate of 54.9 percent against lefties and a still higher-than-average 41.5 percent against righties.

St. Louis left-handers are preferred given that Adelman leans so flyball heavy against them, so Matt Carpenter, Matt Adams (assuming he’s in the lineup), and Dexter Fowler are good options. Fowler is a switch-hitter who is better from the right side, but he’s still above average from the left side. 

But what makes St. Louis so stackable is the fact that they have plenty of righties who do just fine without the platoon advantage. Aledmys Diaz, Randal Grichuk and Stephen Piscotty all have above average numbers against right-handed pitching.

St. Louis has used way too many lineups recently to be able to venture a guess as to what stacks to use tonight, but Carpenter should be included in most two-man stacks with a hitter listed above if they’re hitting consecutively. And a Cards stack could go five deep given all their right-handers that are worth a look.

Chicago White Sox

Matt Boyd, who will face the White Sox tonight, is unlike Adelman in that he only leans flyball heavy against hitters from one side of the plate. Against same-handed hitters, the left-handed Boyd keeps the ball primarily on the ground with a 46.3 percent groundball rate. But when hitters have the platoon advantage, they’re able to elevate the ball as Boyd owns a 50 percent fly ball rate against right-handers.

When pitchers have big splits like that, it can sometimes be difficult to string together a stack. Thankfully, the White Sox can string together a big group of righties to face a left-handed pitcher. The last two times Chicago has faced a lefty, only one left-handed hitter has made it into the lineup. And the White Sox have good career numbers against Boyd with a .398 wOBA in a combined 81 PA.

Jose Abreu (who expects to return to the lineup tonight) and Todd Frazier are the obvious right-handed bats with pop. Tim Anderson, Avisail Garcia and Tyler Saladino also have above average career numbers vs. LHP, though none of them have a ton of power. The switch-hitting Melky Cabrera is also in play. He has better numbers for his career vs. RHP, but he was better against LHP last year.

Two-man: Jose Abreu, Todd Frazier

Three-man: Jose Abreu, Todd Frazier, Avisail Garcia

Five-man: Tyler Saladino, Melky Cabrera, Jose Abreu, Todd Frazier, Avisail Garcia
