The main piece in the Nolan Arenado has flourished for the Rockies thus far, especially at Coors Field.
In his first five starts at Coors Field this year, he had an ERA of 0.95.
Overall, he struggled to start the season (6.35 ERA in his first seven starts) but in his following seven starts, he had an ERA of 1.28.
However, his injured list stint makes his case weaker and, if he does get selected to it, he would have to be replaced on the roster.
Germán Márquez is another player, like Trevor Story, who’s All-Star game case has strengthened in recent weeks.
After all, he didn’t have much of a case at all to start the season since he had an ERA of 6.21 in his first seven starts. But in the 10 starts since then, he has an ERA of 2.32. If you remove one of those ten starts (his start on June 12 in Cincinnati), his ERA in the other nine starts is a sparkling 1.33.
Overall on the season, he has an ERA of 3.62 and an ERA+ of 126, which is the best among any Rockies pitcher with 25 or more innings pitched.
