Carlos Correa represents everything the Houston Astros hope to stand for over the next few years. So it would be impossible to overstate how important Monday is to the franchise as the 20-year-old shortstop and MLB’s No. 2 prospect makes his debut.

The Cardinals put up a three-run eighth inning against the Dodgers’ bullpen to come from behind to win, 4-2, on Sunday at Dodger Stadium and earn a win in the four-game series.

Leading up to when the first pick by the Arizona Diamondbacks is announced by Commissioner Rob Manfred shortly after 7 p.m. ET on Monday, Jim Callis and Jonathan Mayo will be working the phones, texting and emailing decision-makers in the scouting industry, as they try to line up their final mock Drafts. Along the way, they hear a lot of rumors, buzz, talk of guys with helium and guys sliding. They will bring that information to everyone here in MLBPipeline.com’s Draft Buzz

Carlos Correa, the 20-year-old shortstop who many consider the top prospect in all of baseball, is set to make his Major League debut on Monday when the Astros open a three-game series against the White Sox in Chicago.

On Monday, coverage of the 2015 Draft will begin at 6 p.m. ET on MLB.com and MLB Network leading to the first round at 7 p.m., with the first 75 picks coming off the board.

The Cubs needed five pitchers to defeat the Nationals, 6-3, in front of a sellout crowd at Nationals Park on Sunday afternoon. It ended up being a great weekend for Chicago, which took three out of four games from Washington.

When the season started, insiders said the Yankees are a team capable of winning 90…or losing 90. A punchy offense and terrific back end of the bullpen has put the Yankees on pace to hit the 90 mark. Is this sustainable? In this division, the answer is a very definitive…maybe.

The first part of Sunday was spent wrapping up a discussion about outfielders that could be available late in the Draft, but then the talk in the D-backs Draft room returned to the No. 1 overall pick.

Nationals center fielder Denard Span suffered back spasms during a 6-3 loss to the Cubs on Sunday afternoon and had to be taken out of the game after the seventh inning. Danny Espinosa replaced Span in the lineup and found himself playing left field for the first time in his career.

Although he’s known primarily for his defensive gems as part of the Marlins’ heralded double-play combo, Adeiny Hechavarria can still step outside that and deliver some of his “sneaky power.”

College of Southern Nevada pitcher Phil Bickford, MLB.com’s No. 21 Draft prospect, tested positive for marijuana in a pre-Draft drug test, MLB.com’s Jim Callis has confirmed. Baseball America was the first to report the news.

Kris Bryant was a home run shy of his first career cycle Sunday, as the Cubs clinched the four-game series from the Nationals with a 6-3 win.

Chris Colabello hit a walk-off single in the bottom of the ninth inning as the Blue Jays capped a dramatic 7-6 victory over the Astros on Sunday afternoon at Rogers Centre to extend their winning streak to a season-high five games.

The Red Sox came roaring back with their best comeback of the season on Sunday afternoon, completing a three-game sweep of the Athletics with a 7-4 victory at Fenway Park.

With just a couple of days before the start of the 2015 Draft, it would be nice to report with certainty what the top of the first round is going to look like. Alas, that still isn’t feasible, though we — Jim Callis and myself — will do due diligence in trying to project the entire first round as accurately as possible late Sunday night and into Monday morning.

Gerrit Cole, the first player overall selected in the 2011 Draft, perfectly illustrates that importance of Monday night’s migraine-inducing exercise for the D-backs and Astros, along with every other team holding a high pick.

In the midst of a 3-1 victory over the Mariners — in which the Rays closed out a 10-game road trip with seven wins, including three out of four in the weekend series — Chris Archer put up numbers never seen before and solidified a growing Cy Young Award bid.
