LEADING OFF: Hammel vs Strasburg in DC, Kershaw in control

A look at what's happening all around the majors today:

---

WINNERS ALL AROUND

Two impressive winning streaks are on the line in the Cubs-Nationals series finale. Chicago starter Jason Hammel (7-2, 2.36 ERA) is 9-0 with a 3.16 ERA in 12 career starts against the Nationals. He'll oppose Stephen Strasburg (10-0, 3.03), who has won 13 straight decisions dating back to last season. Strasburg hasn't faced the Cubs since August 2013.

IN THE ZONE

Clayton Kershaw (9-1, 1.52) tries to keep up his dominant recent run when the Dodgers face the Diamondbacks. Kershaw has a 20.3 strikeout-to-walk ratio this year, and if he finished the season at that clip, it would be the second-best ever - behind Lady Baldwin's 21.0 in 1884. The best K/BB ratio since 1884 was posted by Phil Hughes, who had an 11.6 mark in 2014.

TOUGH BREW

Former Brewers nemesis Johnny Cueto (9-1, 2.16) tries again for his 10th victory and his eighth straight winning start against Milwaukee when the Giants conclude their homestand. Cueto, who pitched previously in the NL Central for the Cincinnati Reds, is 10-3 with a 2.79 ERA in 19 career starts vs. the Brewers.

FRIENDS, ENEMIES

Yankees manager Joe Girardi and Rockies skipper Walt Weiss are longtime friends facing each other for two games. New York selected Weiss' son, Bo, in the 29th round of the draft last week. ''It's crazy,'' Walt Weiss said. The younger Weiss committed to pitch for North Carolina but could sign with the Yankees.

SECOND START FOR DESCLAFANI

Reds right-hander Anthony DeSclafani (0-0, 1.50) will make his second start of the season and his third career start against the Braves. DeSclafani began the season on the disabled list with a strained left oblique. He came off the DL on Friday and allowed eight hits and one run while getting a no decision in a 2-1 win over Oakland. DeSclafani is 0-1 with a 5.73 ERA in two starts against Atlanta, both in 2015.

BANGED UP

The Phillies hope to get third baseman Maikel Franco back when they face Toronto. Franco has a sprained right knee and has missed two games after landing awkwardly trying to tag a runner Sunday. Franco is hitting .252 with 11 homers this season.
