Nobody has more wins this month than the Red Sox (19).

No team has a better batting average (.288), OPS (.824) or slugging percentage (.472) in May than this team.

Their starting pitchers have combined for a 3.69 ERA in the last 29 days.

And, most importantly, the Red Sox find themselves in first-place on May 30 for the first time since 2007 (when they were 10 ½ games ahead of second-place Baltimore).

So, the question is: How good is this team?

The answer will largely depend on injuries, the ability to some surprises to sustain their performances (see Tim Wakefield, Alfredo Aceves, Rich Hill), and … did we say injuries?

But, as we sit here, perhaps one of the most telling aspects of this club is that you could make an argument that the Red Sox have five players who are the best in the American League at their respective positions.

This list could be extended to Rich Hill, who is one of two relievers with at least eight appearances to not have allowed a run, joining Jose Contreras.

But for now, let’s focus on the regulars:

STARTING PITCHER: JOSH BECKETT

Yes, his ERA jumped up to a whopping 1.80 after giving up two runs in six innings Sunday night (1.00 for the month of May), but that is still best in the AL. He also has the league’s best batting average against (.189).

In the conversation: Trevor Cahill, Jered Weaver, James Shields, Justin Verlander, Alexi Ogando. Jon Lester, Clay Buchholz.

FIRST BASEMAN: ADRIAN GONZALEZ

He has the most RBI among AL first baseman (45), but doesn’t lead in any other major offensive category. Gonzalez has the third-most homers (9), the second-best OPS (.911), and trails Casey Kotchman in batting average (although the Rays’ first baseman has 108 fewer plate appearances). Still, consider the overall production, along with the fact he hasn’t made a single error, and the first-year Red Sox makes a strong case.

In the conversation: Miguel Cabrera, Mark Teixeira, Paul Konerko.

THIRD BASEMAN: KEVIN YOUKILIS

Sure, Youkilis might have a subpar batting average (.252), but no AL third baseman has a better OPS (.876), with Adrian Beltre the only member of the group totaling more extra-base hits (23 to Youklis’ 22).

In the conversation: Alex Rodriguez, Adrian Beltre, Wilson Betemit.

CENTER FIELD: JACOBY ELLSBURY

As a leadoff hitter, Ellsbury joins Minnesota’s Denard Span in scoring the most runs in the AL (29), while totaling the best batting average (.318) and second-best OPS (.848). When comparing him to centerfielders, Ellsbury’s OPS is second only to Curtis Granderson. The Sox’ outfielder also has more stolen bases (19) than any other AL player at his position.

In the conversation: Curtis Granderson, Denard Span, Melky Cabrera, Adam Jones

DESIGNATED HITTER: DAVID ORTIZ

No DH has more home runs (10), and only Travis Hafter – who comes in at 85 less plate appearances than Ortiz – claims a higher OPS than the Sox’ slugger’s .902. Ortiz has more total bases than any other designated hitter (100), while having reached base above and beyond any of his counterparts (78).

In the conversation: Billy Butler, Vlad Guerrero, Travis Hafner, Victor Martinez, Johnny Damon.
