If you’re a fan of high scoring baseball, Friday has a chance to be your kind of day.

Today’s slate is rife with games being played in favorable ball parks for hitters. The most obvious example of that is our first Coors Field action of the season as the Rockies play their home opener against the Dodgers. But there are also games in Arizona, Milwaukee, Baltimore and Texas.

On top of the ballpark factor, most teams are playing their fourth or fifth game of the season, which means many end-of-the-rotation arms are in play today. Of today’s starters, 22 started a double-digit number of games last year, and only four of those 22 posted and ERA below 4.00 on the season. If we’re being a bit more charitable, seven of them cracked the 4.00 mark in xFIP.

Another thing to consider today is weather. Thankfully there won’t be much of an issue with rain today, but the temperatures across the nation should be considered. Jeff Zimmerman of Fangraphs has shown the impact temperature can have on run scoring, which boils down to warmer temperatures lead to more runs scored. Here’s the national forecast for the day.

As you can see, the northeast is experiencing a cold snap. Game time temperatures are expected to be below 50 for the following games (starting time temperature in parentheses):

  • Atlanta Braves at Pittsburgh Pirates (39°)
  • Boston Red Sox at Detroit Tigers (42°)
  • Washington Nationals at Philadelphia Phillies (47°)
  • New York Yankees at Baltimore Orioles (47°)
  • Miami Marlins at New York Mets (47°)
  • Minnesota Twins at Chicago White Sox (43°)

Not that it’s hot anywhere in the country this early in April, but by comparison, games in other parts of the nation have much more favorable conditions. It will be 76° in Texas at game time, 71° in Colorado, and, even though the roof neutralizes some impact of this, 89° in Arizona.

It’s not a surprise to see that the teams with the four highest expected run totals of the day per Vegas are all playing in those three ball parks. The only other team joining those four with an expected run total higher than five is the Cubs in a favorable park in Milwaukee.

The Coors game will feature a couple of lefties on the hill in Kyle Freeland and Hyun-Jin Ryu.

Freeland is making his major-league debut tonight in Coors Field, which sounds like a nightmare. But if there’s a bright-side for him it’s that the Dodgers ranked dead last in wRC+ vs. LHP last season. Adrian Gonzalez was downright awful against lefties last year (.065 ISO), Corey Seager was below average against them (96 wRC+), Yasmani Grandal is a switch-hitter with more pop from the left side, and right-hander Justin Turner has bizarre-but-well-established reverse splits.

There’s always an argument to fade Coors just in the interest of being contrarian, but there’s an additional case to be made against fading Dodgers, even in this ball park against a debutante.

Ryu is making only his second start since 2014, so don’t be wary of Colorado hitters simply because you remember Ryu had a couple good seasons more than two years ago. And don’t be hesitant with Colorado left-handers either. Ryu has slightly reverse career splits with a better HR/9, K-BB% and xFIP against right-handed hitters. To be clear, Colorado’s left-handed outfielders do have normal splits, so the focus should remain on Rockie right-handers. But given Ryu’s splits, a left-hander can be included in a Colorado stack if you’re trying to stack consecutive hitters.

Moving away from Coors, the top half of the Cleveland lineup looks lethal in Arizona against Shelby Miller.

Miller held his own against same-handed hitters last year, but he had a 1.12 HR/9 and 4.86 xFIP against lefties. The top of Cleveland’s order features three switch hitters that were all very good against right-handed pitching last year. Carlos Santana, Francisco Lindor and Jose Ramirez posted wRC+ marks of 144, 119 and 119 respectively last season against RHP. Those three along with the left-handed Michael Brantley make for a very appealing stack, especially when you consider how weak Arizona’s bullpen is this season.

Opposing Miller is Josh Tomlin who has a history of struggling with the long ball as well as some non-traditional splits, which is a nice recipe for stacking against. Tomlin has a career HR/9 of 1.56, and his HR/9 has been at least that high in each of the last three seasons. He’s also allowed homers at an almost identical rate to lefties and righties in his career.

Arizona right-handers A.J. Pollock and Paul Goldschmidt both have above average numbers against right-handed pitching for their careers, so you should not shy away from them. Those two along with left-handers David Peralta and Jake Lamb have hit 1-4 in Arizona’s two games thus far against right-handed starters.

In Texas, right-hander Raul Alcantara will make his sixth big league start, and he has allowed nine home runs in just 22.1 innings in his first five starts. Texas’ lineup features three left-handed in the top half of the order in Shin-Soo Choo, Nomar Mazara and Rougned Odor. Mike Napoli hits in the middle of that trio, and Nap has an above average wRC+ and ISO against right-handed pitching for his career.
