Bartolo Colon (thumb) pitched well in Sunday's loss to the Braves, allowing one run on six hits over seven innings.
Colon was hit with a comebacker off the right thumb in his last start, but he showed no ill-effect from that injury on Sunday. The only run to score against the 43-year-old right-hander came home via a first-inning solo homer off the bat of Freddie Freeman. Assuming the thumb is good-to-go moving forward, Colon will carry a 2.86 ERA, 1.17 WHIP and 58/14 K/BB ratio (88 innings) into a home start against the Cubs next time out.
Tanner Roark fired seven shutout innings Sunday in the Nationals' 3-2 defeat of the Brewers.
Roark scattered seven hits -- two doubles, five singles -- and one walk across his seven scoreless frames. He struck out seven. The 29-year-old right-hander has been a nice surprise for the Nationals this season, now with a 2.96 ERA, 1.22 WHIP, and 89/32 K/BB ratio in 100 1/3 innings. He finished with a 4.38 ERA in 2015. Next is a home start versus the Reds.
Chris Davis connected for a first-inning grand slam in Sunday's 12-5 win over the Rays.
Davis launched his granny off of Rays starter Drew Smyly in the first inning. He would later add a single to finish 2-for-4. The slugger is working to a .240/.355/.498 triple-slash with 18 homers and an even 50 RBI over 267 at-bats. It will take a nice second-half power push to reach the 47 dingers he hit in 2015.
Shawn Kelley allowed a run in 1 1/3 innings Sunday but was able to grab his third save.
Kelley yielded a two-out homer to Brewers catcher Martin Maldonado in the bottom of the ninth and Jonathan Villar tripled a few pitches later, but Scooter Gennett flied out to Jayson Werth to end it. Kelley has struggled a bit as the Nationals' fill-in closer, but he's definitely the guy to own until Jonathan Papelbon (intercostal) returns from the disabled list.
Pirates designated RHP Curtis Partch for assignment.
That move clears a spot on the 40-man roster for Chad Kuhl who is starting for the Pirates on Sunday. Partch struggled in his lone appearance with the big league club this season, allowing three runs on his inning of work. He's expected to pass through waivers and continue to function as bullpen depth at Triple-A.
