Phillies vs Rockies: 5 players to watch for in the series

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.
