Detwiler And Werth Lead Nats Over Snakes, 4-1

After the emotional Sturm und Drang that was this past weekend’s three-game series against the Phillies, the Washington Nationals needed a nice, quiet game that wouldn’t overly tax the bullpen. Luckily, they got just that kind of performance from Ross Detwiler, who allowed just one run on six hits over 6.2 innings as the Nationals defeated the Arizona Diamondbacks 4-1 Monday night at Nationals Park.

On a night when most of the focus of the Washington brass and media was on Stephen Strasburg’s third rehab start with Class-A Hagerstown (for the record, Strasburg went three innings and allowed one earned run on two hits, walked one and struck out six while throwing 60 pitches in front of Nationals General Manager Mike Rizzo and principal owner Mark Lerner), the 25-year-old Detwiler continued to build on his impressive year, pitching into the seventh inning as a starter for the first time since June 20, 2009.

How much of Detwiler’s improvement is genuine progress and how much is a product of mere year-to-year statistical variance is hard to gauge. His strikeouts per nine innings ratio has jumped to 6.61, up from 5.16 in 2010, though he only managed just three strikeouts Monday night after fanning seven in his previous start against Cincinnati. Detwiler’s also been getting more ground balls with his more effective sinker. 48.9 percent of all balls in play against him have been grounders this season, up from an even 43% in 2010. As a result, both Detwiler’s Fielding Independent Pitching (FIP) and expected Fielding Independant Pitching (xFIP) have dropped by more than a run from 2010 (the FIP has fallen from 5.64 to 4.54, while his xFIP has fallen from 4.97 to 3.96).

But there’s no denying that the left-hander has gotten very lucky when it comes to stranding runners on base. Entering Monday night, Detwiler’s left on base percentage was an unsustainable 86.6 percent. Remarkably, he managed to bolster that number on Monday night, as Arizona stranded five of their seven runners while he was in the game. Indeed, the most crucial moment of Detwiler’s outing came in the top of sixth inning, when he allowed a single to Justin Upton and walked Chris Young to load the bases with two outs and Washington on top 4-0.  Henry Rodriguez was warming up in the Washington bullpen, and on another night, Nationals manager Davey Johnson might have pulled the trigger on a pitching change. But this time, he only visited the mound to have a word with Detwiler, and his faith was rewarded when Detwiler induced Paul Goldschmidt to ground into an inning-ending force play.

Along with Strasburg and Jordan Zimmermann, the development of Detwiler will be fascinating to watch. The good news is that the Nationals and their fans will have plenty of time to make a determination. Detwiler has one more full season before being eligible for arbitration, and he won’t be a full-fledged free-agent until after the 2015 campaign.

On the other side of the coin, the Nationals offense didn’t make Arizona starter Joe Saunders work particularly hard (he had only thrown 90 pitches when he made way for a pinch-hitter after six innings), but the Nationals didn’t to have particular trouble hitting certain of his pitches. As it turned out, Saunders’ two-seam fastball was particularly ineffective, and it was responsible for all of Washington’s runs. In the bottom of the second, Jonny Gomes dropped a two-seamer into right field to drive in Jayson Werth for the first run of the game. Two innings later, after a Ryan Zimmerman infield single and a walk by Michael Morse, Werth hit another Saunders two-seamer quite a bit farther. The ball sailed into the front row of the right-field seats for a three-run home run that turned a 1-0 lead into a 4-0 cushion and capped off a fine night at the plate for Werth (2-for-4 with his other hit a pulled double into the left field corner in the second). The well-paid right fielder is very quietly having a fine second half to the season, with a .358 on-base percentage and a .778 OPS in 137 plate appearances since the All-Star Break entering Monday night’s game. While those numbers still don’t measure up to his outstanding statistics in Philadelphia, Nats fans can now expect, rather than hope, that Werth has got his feet under him in the nation’s capital.

  1. Samuel,

    That is some fine analysis, combining sabermetric thinking and good observations.

    Where do you get your info on the pitches? f/x? Do you get a slot in the media booth?

    Look forward to your coverage. Do you have a blog also?

  2. Jay,

    Glad you liked the piece. I get my info re: pitches and pitch types from Brooks Baseball’s pfx page, yes. For guys’ offensive stats, I use either Baseball Reference or Fangraphs. One’s as good as the other to me.

    We Love DC is credentialed by the Nats, and coverage of the games is split among myself, Tom Bridge, and Rachel Levitin. We all cover these home games as often as our day jobs allow, so I do hope you’ll come back and check us out again.
