LEADING OFF: Diamondbacks pick 1st in draft, Astros sliding

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

---

ON THE CLOCK

The Arizona Diamondbacks have the first pick in the amateur draft, which begins at 7 p.m. EDT from MLB Network studios in Secaucus, New Jersey. It's the 50th anniversary of the initial draft in 1965 - and the first for new Commissioner Rob Manfred. This year's class is deep at shortstop, with LSU's Alex Bregman, Vanderbilt's Dansby Swanson and Florida high schooler Brendan Rodgers among the top prospects.

HOMECOMING

Padres outfielders Justin and Melvin Upton Jr. and closer Craig Kimbrel return to Turner Field for the first time since being traded from Atlanta to San Diego before the season. Kimbrel needs one save to become the youngest player in big league history to reach 200, having piled up 186 with the Braves.

SLIDING

The AL West-leading Astros have lost a season-high four in a row as they visit the Chicago White Sox. At 20, Houston shortstop Carlos Correa is set to make his major league debut after being the top overall draft pick in 2012.

NICE TIMING

Chris Colabello has a 17-game hitting streak for Toronto, the longest active string in the majors. He extended it with a two-run single in the bottom of the ninth inning that beat Houston on Sunday.

TAGGED

Royals outfielder Alex Rios is 13 for 27 with four doubles and a home run lifetime against Phil Hughes, the Twins' starter in the series opener.

STARTING UP

Pirates veteran A.J. Burnett has won six starts in a row. He'll face the Brewers, and is 2-6 in 11 career starts against them.
