I have allocated the All-Star roster as follows: Each team has 21 batters and 13 pitchers. These allocations are roughly in line with allocations of recent All-Star game rosters:

• Starting batters at each of the nine positions, with DH substituting for pitcher in both leagues (note that DH is a rule at all All-Star Games, regardless of the league hosting).
• Reserves at each of those nine positions.
• A third catcher and two additional batters, one of whom is the "34th man," who will be selected by fans in the weeks prior to the Midsummer Classic.
• Eight starting pitchers.
• Five relievers, including at least one lefty and at least one middle reliever.
• All 15 National League and all 15 American League clubs are guaranteed at least one slot.

34th man: Manny Machado, Baltimore Orioles

This would've been Ian Kinsler's slot if he was still healthy. Machado is leading all AL third basemen in WAR and all AL fielders in defensive war. He also has a solid triple slash of .328/.362/.527, leads the AL in doubles, and is third in total bases.

33rd man: Jose Altuve, Houston Astros

Altuve is the only bright spot on a 12-32 Astros squad. Altuve is second among AL second basemen in both WAR (2.0) and batting average (3.3). He's also turned the most double plays in the AL.

Backup DH: Lance Berkman, Texas Rangers

Berkman is one of only two DHs to be hitting .300 on the season, and he's leading all DHs in hits. Fat Elvis is also second among DHs in WAR.

Starting DH: David Ortiz, Boston Red Sox

Despite having about 50 fewer at-bats than most other DHs, David Ortiz is leading them in WAR, being the only DH with WAR above 1.0. He leads all DHs in total bases and extra-base hits.

Ortiz has a lights-out triple slash of .364/.407/.667, good enough for an OPS of 1.074. He's also gone yard seven times and driven in 29.

34th man: Brandon Phillips, Cincinnati Reds

Phillips is second in the NL in RBI with 36. He also leads all NL second basemen with 80 total bases and seven homers.

33rd man: Marco Scutaro, San Francisco Giants

A few years ago, somebody put Omar Infante and Martin Prado on the All-Star team, primarily due to positional eligibility. Scutaro offers some of the same flexibility, but with one major upside: He's also fourth in the league in hits and has a triple slash of .331/.375/.436.

Backup DH: Starling Marte, Pittsburgh Pirates

Marte is 8th in the NL in WAR with 2.3, and is one of three players with an OPS over .800 and double-digit stolen bases. He's in the top five in the NL in both runs and hits on a triple slash of .305/.372/.463.

Starting DH: Joey Votto, Reds

Votto is leading all NL first basemen in batting average, and is second in the NL in OPS. He's also in the top ten in the NL in a host of other categories, including WAR, hits, doubles, batting average and walks. 

Closer No. 1: Mariano Rivera, New York Yankees

Look for this to be Mariano's last ninth inning in the All-Star Game. Rivera is leading all AL closers in saves, having converted all 16 of his save opportunities this season.  

Closer No. 2: Tom Wilhelmsen, Seattle Mariners

Wilhelmsen is leading all AL closers in ERA with a shockingly-low 0.50 (best among any righty in the league), to go along with a WHIP of 0.61. He also leads all AL closers in WAR with 1.1, and is one of six AL closers to have notched double-digit saves.

Closer No. 3: Casey Janssen, Toronto Blue Jays

Janssen is one of six AL closers with double-digit saves, and one of only two AL closers with a WAR of 1.0 or better. Janssen has allowed just four hits and one earned run in 13 innings of work, for a 0.31 WHIP and a 0.69 ERA.

Lefty Reliever: Glen Perkins, Minnesota Twins

There are a few distinctions about Perkins. He is leading all MLB lefties in saves. He is one of only three AL lefty relievers with 14 or more strikeouts per nine innings, and is the only one of those three with a sub-1.00 WHIP.

Middle Reliever: Tanner Scheppers, Rangers

One again, the Rangers are getting it done in middle relief. Among AL righties with 15 or more innings, Scheppers is third in ERA at 0.79, with a WHIP of 0.79 as well. Due to eight holds and three wins in relief, he is one of a handful of middle relievers with a WAR better than 1.0.

Closer No. 1: Jason Grilli, Pirates

Last season, Jason Grilli was one of baseball's best setup men. Now he's one of baseball's best closers.

Grilli is leading the majors in saves with 17, and this on a 0.92 ERA that is the fourth-best among players with 15 or more frames. Grilli is averaging an astonishing 14.2 strikeouts per nine, and an equally good 7.7 strikeouts per walk during the best campaign of his career.

Closer No. 2: Edward Mujica, St. Louis Cardinals

Mujica is one of two NL closers with a WAR over 1.0, and is one of four NL closers with 13 or more saves. Mujica's 0.53 WHIP is the best in the majors among pitchers with 15 or more frames.

Closer No. 3: Craig Kimbrel, Atlanta Braves

Kimbrel is second in the NL in saves with 14.  He also is averaging 14 strikeouts per nine innings, and has a sub-1.00 WHIP.

Lefty Reliever: James Russell, Chicago Cubs

James Russell has one of the best ERAs (0.52) and OPS-conceded marks (.477) among lefty relievers with 15 or more frames under their belt. In 17.1 innings, he's recorded 19 strikeouts with seven holds and a win in relief.

Middle Reliever: Luke Gregerson, San Diego Padres

Gregerson is the only Padre who is anywhere near the top of a positional ranking. He is second in WHIP among pitchers with 15 or more innings. He adds to that a respectable 1.00 ERA, nine holds and two wins in relief.

Starting Catcher: Joe Mauer, Twins

Mauer is once again leading all backstops in batting average, and is in the top ten in the AL in OPS. He leads all AL backstops in WAR by a considerable margin, due to, among other things, being second among AL catchers in double plays turned and players caught stealing.

Backup Catcher: Carlos Santana, Cleveland Indians

Santana leads all AL backstops in OPS at .963, a number good enough for fourth in the league. Though Santana is second in the majors in offensive WAR, his poor showing on defense puts him second among AL catchers in total WAR behind Mauer.

Third Catcher: Salvador Perez, Kansas City Royals

Perez is second among AL catchers in batting average with .307, and tied for third in WAR with 0.8. He's also second among AL catchers in hits behind Mauer.

Starting Catcher: Buster Posey, Giants 

The reigning NL MVP is again leading all NL backstops in a bunch of categories, including OPS (.918), OBP (.396), total bases (70) and doubles (11). He also has the seventh-best offensive WAR in the league.

Backup Catcher: Yadier Molina, Cardinals

Molina is the only NL catcher to be hitting better than .300 on the season, good enough for fifth in the league.

Third Catcher: John Buck, New York Mets

The hometown catcher is leading all NL backstops in homers (10) and RBI (31). Both of those numbers are good enough for top five in the NL. 

Starting Second Baseman: Dustin Pedroia, Red Sox  

Pedroia is leading all AL second basemen in WAR with 2.7 (better than any non-pitcher in the AL) and in batting average at .343 (good enough for third in the AL). Pedroia has scored 32 times, stolen eight bases and has yet to commit an error at second base.

Backup Second Baseman: Robinson Cano, Yankees 

Cano is leading all AL second baseman in OPS at .899, and in homers with a dozen. He also has one of the ten-best slugging percentages in the AL, and is second in the AL in total bases.

Starting Shortstop: Jhonny Peralta, Detroit Tigers

Peralta is the only AL shortstop hitting over .300 this season, and is second among all AL shortstops in WAR with 1.5.

Backup Shortstop: Elvis Andrus, Rangers

Andrus has a slight edge over Peralta in WAR, but has a much worse triple slash of .282/.330/.348. Andrus leads all shortstops in hits with 51, and is also third in the league in stolen bases with 12.

Starting Second Baseman: Matt Carpenter, Cardinals

Carpenter leads all NL second baseman in WAR with 1.9, and in OPS at .818. He's also second in the NL in runs, third in doubles and has turned five double plays this season.

Backup Second Baseman: Chase Utley, Philadelphia Phillies

Utley leads all second baseman in homers with seven, and is a close second to Carpenter in OPS. He also is the only Phillies batter with a WAR above 1.0, and is one of two NL second basemen with 25 or more runs driven in.

Starting Shortstop: Troy Tulowitzki, Colorado Rockies

Tulo leads NL shortstops in a number of power-related categories, including OPS (.996, sixth in the NL), slugging (.590, 4th in the NL) and homers (eight, 10th in the NL).  He also leads the NL in RBI with 37.

Backup Shortstop: Jean Segura, Milwaukee Brewers

Segura has more total bases (94) than any NL shortstop, a better batting average (.364) than any NL shortstop, and a better WAR (2.6) than any NL shortstop. He's also stolen 14 bags.

Matt Moore, Tampa Bay Rays

Matt Moore is 8-0. Nuff said. 

Felix Hernandez, Mariners

The starting gig was King Felix's to lose, and he lost it with a poor performance (six runs allowed in six innings) in his last outing, combined with back problems. Hernandez is in the top five among AL starters in a number of categories, including ERA, strikeouts and pitcher's WAR.

Hisashi Iwakuma, Mariners

Iwakuma (5-1) is second among AL starters in ERA at 1.84, and leads them in WHIP at 0.78. He's also 4th in the AL in pitcher's WAR, leads all AL starters in OPS allowed and is second among AL starters in strikeouts-to-walks ratio.

Hiroki Kuroda, Yankees

Kuroda (6-2) is third among AL starters in ERA at 1.99, fourth in WHIP at 0.95 and second in OPS allowed at .546.

Justin Masterson, Indians

Yu Darvish, Rangers

Darvish is one of three pitchers with seven victories, and is leading the league in both strikeouts and hits allowed per nine innings.

Chris Sale, Chicago White Sox

Sale is one of five AL pitchers with eight quality starts. He is second in the league in both pitcher's WAR and WHIP.

Matt Harvey, Mets

With 3.1, Harvey (5-0) has the second-best WAR in baseball, and adds to that the best WHIP (0.72). He allows a staggeringly-low OPS of .417, and is second in the NL in strikeouts with 68.

Shelby Miller, Cardinals

Miller (5-2) is second in the NL in ERA at 1.40 and fourth in WHIP at 0.88. He is in the top eight in the National League in a number of statistical categories, including wins, strikeouts, WAR and OPS allowed.

Jordan Zimmerman, Washington Nationals

Zimmerman is the only man in the National League with seven victories to his name, and has thrown more complete games (3) than any other pitcher in the Senior Circuit. He's also second in the NL in WHIP with 0.87 and fifth in the NL in ERA at 1.62.

A.J. Burnett, Pirates

Burnett (3-4) is leading the NL in strikeouts with 79, and is one of 11 pitchers with seven or more quality starts. He's also 10th in the NL in ERA and sixth in OPS allowed (.572).

Backup First Baseman: James Loney, Rays

Loney is second in the AL in batting average at .356, best among first basemen. He's also sixth in AL in OPS at .926.

Starting Third Baseman: David Wright, Mets

The hometown third baseman is leading all NL third basemen in WAR by a substantial margin, and also has the lead in OPS at .944. His .416 OBP is the third-best in the majors, and he also has three triples and 10 stolen bases.

Backup Third Baseman: Pablo Sandoval, Giants

Panda is leading all NL third basemen in total bags with 80, and has the second-best batting average among NL third basemen at .302. He's also hit six dingers, and is fourth in the league in RBI with 32.

Backup Outfielder: Shin-Soo Choo, Reds

Choo is one of three NL players with an OPS over 1.000, thanks mostly to his .456 OBP that is second in the majors. Choo has created more runs (46) than anyone else in the NL, is second in walks, fifth in total bases and eighth in dingers.
