Colorado’s rotation is the healthiest in baseball with all five of their original starters with 13 starts. Marquez is second on the team with four wins and first with six losses, a unique combination for a unique ballclub.
At first the 4.79 ERA is something that turns people away from the 23-year-old, who is already in his third season with the Rockies. However, he’s performed in outstanding fashion on the road in six games with a 2.06 ERA with batters hitting .202.
Those numbers are scary, and likely show what Marquez can be outside of a hitter’s friendly ballpark like Colorado. Each of his last three starts have been at home where he’s allowed 10 earned runs with 18 strikeouts in 17 innings. That includes a one-run, seven inning win against the Reds on May 27.
Marquez doesn’t get many strikes swinging with hitters swinging at an even 10%, and 26% percent of balls are line drives.
Last year in his only start against Philadelphia Marquez went six innings of one-run ball in Citizens Bank Park with six strikeouts and three walks in seven innings. He received a ton of run support thanks to Zach Eflin allowing eight runs in six innings for the Phillies.
