Arizona Diamondbacks Stock Watch: Who’s Hot and Who’s Not

 Hot: Rubby De La Rosa

Last 7 starts: 5-0, 46.0 IP, 2.54 ERA, 26 SO, 17 BB, 4 HR’s, .240 BAA

From the beginning of the season till the middle of June, Chase Anderson was the Diamondbacks most consistent starter.

As I detailed yesterday in my opinion piece, since the All Star Break, De La Rosa earns that nod. He is the only starter that has been able to go deep into games, and the bullpen owes him a meal or two.

Meanwhile the whole starting staff seems to have been inspired by De La Rosa’s success. In 34 starts across 190.2 innings pitched, the D-backs starters ERA is 3.82.

Combine that with the National Leagues best run scoring offense, the D-backs have the 10th best run differential in the majors with 560 RS and 524 RA.

De La Rosa has pitched like an ace keeping the ball down and in the ballpark, generating a lot of ground balls, and using his infield defense to get big outs in big situations.

Welington Castillo has been working with De La Rosa since he came to the D-backs from the Mariners and has made a huge difference.

His success as of late has as much or more to do with the leadership of Castillo calling the game behind the plate, and it seems like they have great chemistry as a battery.

Rubby is a big reason why the D-backs are still in the race for the N.L. West, and he will have to continue his great pitching in order to keep his team in that race.

Next: Paul Goldschmidt
