Will a Rookie of the Year candidate win it for the second month in a row? Will the award go for the second time to a righty who pitched a perfect game? Does a pinstriped captain dominate fan voting again? Are you swayed by a scoreless streak from a converted reliever?
The Head & Shoulders Mane Men are being recognized on MLB.com as the star of each game this season. In addition to that daily selection of the top players, you have a say in deciding the monthly recipient of this fan award. Here is a look at your four candidates for August:
Frazier: It remains to be seen how many innings this top National League Rookie of the Year candidate will get now that Joey Votto is back and Scott Rolen is at third. But watching Frazier light up pitchers in August now presents a pleasant problem for manager Dusty Baker, who has "advice" on the subject from every corner. In August, Frazier produced a line of .330/.393/.587 with a .981 OPS, playing mostly at first. He had six homers, 25 RBIs, three three-hit games and rarely went hitless.
"He's made a case for himself to stick and be a Major League player, for sure," Rolen said.
Hernandez: Matt Cain won this award for his June performance, which included a perfecto, but also a 5-0 mark. Similarly, King Felix threw a perfect game on Aug. 15 -- the first in Mariners history -- and in the non-perfect games he was merely dominant. Hernandez was 4-0 in August and his last outing of the month was a five-hit shutout of the Twins, making it nine consecutive winning decisions -- before losing for the first time on Saturday -- and making him the first pitcher since 1969 to win four 1-0 decisions in a single season.
"Before I came here, I only heard of his pitching line game-in and game-out," teammate Eric Thames said. "But seeing it for myself ... he's the real deal. That's why he's King Felix. That's why he's Cy Young, perfect game and all that stuff. I'm officially a believer, and I'm glad he's on my team."
Jeter: Going strong. It is the only way to describe the Yankees great's career at the age of 38. He had 43 hits in August, his most of any month this season, upping his Major League-leading total to 177 while passing one legend after another on the all-time hits list. Jeter batted .350 during the month and his 25 runs also were his most in any month in 2012. He was in his familiar role of leading the Bombers atop their division.
"Everyone would like to win an award like that," Jeter said of the AL MVP Award, likely to go to someone in a group that also includes Mike Trout of the Angels, Miguel Cabrera of the Tigers and Josh Hamilton of the Rangers. "You ask any player in baseball -- they would like to win an award like that. But I don't think you can allow yourself to think that."
Medlen: No, we can't count July, but here are the facts -- in six starts since entering the rotation on July 31, Medlen has gone 5-0 with a 0.66 ERA in 40 2/3 innings. So that included 4-0 in August, and in his last outing he went eight scoreless to make it 28 1/3 straight innings of goose eggs. Not coincidentally, the Braves started making a run at the Nationals, and one of those wins was a big start on Aug. 22 at Washington.
"He's been unbelievable," teammate Dan Uggla said. "I remember facing him [with Florida] and it wasn't that fun, either. He goes out there, knows what he has to do and executes. He's got that great changeup and puts his pitches where he wants to put them."
The four nominees for the monthly honor are selected by an MLB.com editorial panel.
The last Mane Man of the Month winner was Trout. The top AL rookie survived a one-point race over Pirates center fielder Andrew McCutchen, with Reds closer Aroldis Chapman and Nationals third baseman Ryan Zimmerman as the other nominees that month. Cain and Cole Hamels of the Phillies won for June and May, respectively.
The overall program began with Seattle's Dustin Ackley getting the nod for that first game of the Japan Opening Series on March 28, and it will continue through the World Series clincher. Look back at daily videos to see the conga line of Mane Men so far, including each of these four monthly candidates.
