Diamond notes Werth mentioning: Four hits first for Nationals rightfielder; Detwiler's 18-inning streak

WERTH IT OR WERTH LESS: Much can be said for Jason Werth's baseball intangibles on the field and in the dugout. In fact, too much has been said. The talking heads blather on nightly about his base-running prowess, his ability to make a pitcher work deep into counts, and his stellar defense.

The talk needs to stop until Werth puts his feet on the base-paths enough to justify the big contract he signed last season, when he recorded a career low .330 on-base average and an ugly .232 batting average.

Slapping four hits in a game, like he did against New York, helps, but the Nationals have seen too little of this kind of production. In fact, Tuesday night was the first time the team saw it, period. Werth never had more than three hits in a game during the 2011 season, and notched three hits in only six of the 150 games he played in his debut season with Washington. His last four-hit night was in June of 2009 with Philadelphia.

While ownership can never expect a player to consistently go 4-for-5 at the plate, players paid like top-notch studs are supposed to have banner nights now and then. Werth is not a .300 hitter, and only once in his Major League Baseball career has he produced an average above .275. He has to get on base this season at a higher rate to justify the seven-year, $126 million albatross of a contract he signed with the Nationals that left the rest of the league snickering.

LANNAN DEMOTION PROVES PRESCIENT: Perhaps the chattering will end after Ross Detwiler threw five scoreless, almost flawless innings in Tuesday's tilt against the Mets. Again, prognosticators had a virtual field day when John Lannan and his $5 million guaranteed contract were sent to AAA Syracuse two days before Opening Day, making Detwiler the No. 5 starter in Washington's rotation.

But a closer look at the 26-year-old former first-round pick's last three games, going back to mid-September, shows he should be a more than adequate replacement. Detwiler has pitched 18 consecutive scoreless innings, giving up only nine hits and four walks, while recording 13 strike-outs. He's a power pitcher, where Lannan relies on finesse -- a fine quality if you have Greg Maddux-like accuracy and half of your starts are in a pitcher's ballpark.

The Nationals have waited since 2007 for Detwiler to mature on the mound. He's arbitration eligible in 2013, so Washington's front office needs to determine whether he will be worth future investment in lieu of more one-year veteran signings like Edwin Jackson.

BEAST BESTED BY BACK: Nationals.com is reporting that rightfielder Michael Morse, Washington's biggest offensive weapon last season, was pulled Monday from a rehab game at Class A Hagerstown when he irritated his strained back muscle.

The last is first: Detwiler, offense blow by Mets, 6-2; Zimmerman first National to record 500 RBI

The last pitcher named to Washington’s rotation became the first starter to record a win this season, as Ross Detwiler threw five strong innings while Nationals batters, led by Jason Werth’s four hits, fleeced New York Mets’ pitchers for a 6-2 victory.

In all, Nationals hitters scattered 13 hits in their largest offensive outpouring so far this season.

But it was Detwiler who controlled the game, working quickly and changing speeds to keep Mets hitters off balance. After New York started the night with back-to-back hits from shortstop Ruben Tejada and third baseman Ronny Cedeno, playing in place of an injured David Wright, Detwiler retired 15 of the next 16 batters he faced, striking out six, walking just one and silencing the Citi Field fans.

The 26-year-old, and former first-round draft pick, had one luxury his rotation mates lacked in their starts – an early lead, thanks to Ian Desmond’s lead-off home run. The Nationals’ shortstop started the game by blasting a 2-1 Dillon Gee fastball into the left field seats , his first home run of the season, and the first of his two hits on the night. 

But that’s where the scoring ended until the top of the sixth, when Nationals hitters appeared to figure out Gee’s assortment of breaking pitches and dancing 80 mph change-ups. Ryan Zimmerman led off the inning by ripping a double into the left-field corner. After first baseman Adam LaRoche struck out for the third time against Gee, Werth slapped an 83 mph slider into right field, and Zimmerman sprinted home from second base – Werth’s first RBI of the season. 

Xavier Nady followed with a single to left, and Gee gave way to the Mets bullpen and hard-throwing Bobby Parnell. But New York’s luck didn’t change. Roger Bernadina reached base when New York second baseman Daniel Murphy booted his ground ball, allowing Werth to score from second. 

Catcher Wilson Ramos drove in the third run of the inning with a scorched a line drive double into right centerfield, scoring Nady from second. Pinch-hitter Chad Tracy and Desmond struck out to end the sixth, and leaving the Nationals with their first comfortable lead of the season, 4-0.

 Werth, who was mired in a 1-for-14 hitting slump to start the season, grabbed his second RBI of 2012 with a one-out, line-drive single to centerfield in the seventh, scoring Zimmerman, who walked earlier in the inning. Zimmerman would later record his 500^th career RBI with a sacrifice fly in the eighth inning. 

New York tallied its first run in the bottom of the seventh on a double by Jason Bay, a Lucas Duda fly-ball out and a Justin Turner line drive, but the Nationals bullpen quickly snuffed any further scoring opportunities in the inning. 

The Mets would add their final run in the eighth after Washington set-up man Tyler Clippard walked Tejada leading off the inning, then threw a high breaking pitch to Cedeno, who smashed it over Bernadina’s head in centerfield, scoring Tejada from first.

The Nationals and Mets will meet in a 1:10 p.m. matinee Monday at Citi Field with a battle of arms, as Stephen Strasburg goes head-to-head with New York ace Johan Santana.
