Just How Good Was Jarred Cosart's Rookie Year With Houston Astros?

It’s true that not enough can be said about what the Houston Astros‘ rookies did for their team, both in morale and production. Jarred Cosart is the poster child of that sentiment. As one of the most MLB-ready talents going into the 2013 season, everyone expected him to reach the majors this year. They could not have fully anticipated just how good he would be.

In his debut start for the Astros, Cosart took a no-hitter into the seventh inning against a then red-hot Tampa Bay Rays. He carried the shutout into the ninth, and was eventually relieved. He captured his first, and sadly, only win on that historic debut.

Since that start, Cosart had been on cruise control. He started 10 games for the Astros. Seven of his 10 starts were quality starts; two of the three that weren’t would have been if he could have scratched out another inning. He finished the season with an outstanding 1.95 ERA in 60 innings pitched. Five of his 10 starts came against potential playoff teams. He allowed only 46 hits in those 60 innings. The only downfall to his season was that he had more walks (35) than strikeouts (33), but no one is perfect.

There has to be history made in that rookie season, right?


Since 1901, there have been 100 pitchers to make 10 starts in their rookie season. Cosart’s 1.95 ERA is second lowest on that list, behind only Rube Bressler‘s 1.77 in 1914. So Cosart’s rookie season was the best in about a century. That’s pretty cool.

Cosart will come into Spring Training next year as the assumed ace of a resurgent pitching staff. All he has to do is perform.
