Washington Nationals acquire reliever Brandon Kintzler from Minnesota Twins...

According to a report by Washington Post writer Chelsea Janes this afternoon, the Washington Nationals have acquired 32-year-old closer Brandon Kintzler from the Minnesota Twins.

Nats’ GM Mike Rizzo is reportedly sending minor league lefty Tyler Watson, a 2015 34th Round pick, who was pitching at Low-A Hagerstown in the Nationals’ system, to the Twins.

Kintzler has a 2.78 ERA, a 3.68 FIP, 11 walks (2.18 BB/9), 27 Ks (5.36 K/9) and 28 saves in 45 games and 45 ¹⁄₃ innings pitched, over which opposing hitters have a .246/.297/.329 line this season.

The veteran right-hander avoided arbitration when he signed a 1-year/$2.95M with the Twins this past winter.

Over the last two seasons in Minnesota, the reliever has posted a 2.98 ERA, a 3.64 FIP, 19 walks and 62 Ks in 99 2⁄3 IP, with 45 saves over that stretch.

Kintzler joins a bullpen that also features newly acquired right-hander Ryan Madson and left-hander Sean Doolittle, both of whom came over from the Oakland A’s in an earlier trade this month, and the Nationals have Shawn Kelley and hopefully righty Koda Glover returning at some point to a bullpen that has been a weak spot for an otherwise strong team so far this season.

We’ll update here if any other moves roll in now that the deadline has passed, but Rizzo added two relievers to the bullpen and Howie Kendrick to the bench.

So how are we grading the work the Nationals have done to improve their roster over the last few weeks? Did Rizzo and Co. in the Nats’ front office do enough?

How about the relatively low cost the Nationals paid to add three arms to the bullpen and a bat to the bench?

What about the moves the rest of the playoff hopefuls have made? Did the Nationals keep up with what the rest of the contenders have done?
