Hot- David Ortiz

Ortiz had the best April of his career, batting .405 with six homers and 20 RBI -- all tops on the Sox. Big Papi hit .543 at Fenway Park in the season's first month. (Photo by Elsa/Getty Images)

Hot- Dustin Pedroia

Dustin Pedroia was again a constant in the Red Sox lineup and infield. "The Muddy Chicken" started the season off with a .301 average in April with three homers and seven RBI. (Photo by J. Rogash/Getty Images)

Not- Kevin Youkilis

It was a tough start for Kevin Youkilis, who began the year just 2-for-20 and was called out by his new manager just two weeks into the season. He finished the month with a .219 average and nine RBI. He was scratched from the final two games of the month with a bad back. (Photo by David Banks/Getty Images)

Hot- Daniel Bard

Minus a little gaff in the media about his brief stint back in the bullpen, Bard has been a solid addition to the Red Sox' rotation. Their 5th starter is 2-2 with a 3.79 ERA, picking up one of his wins in relief, and went seven innings of 2-run ball in his last outing of the month. (Photo by Elsa/Getty Images)

Not- Front Of The Rotation

The front end of the Red Sox' rotation was shaky to start the season, although they have turned it around a bit as of late. Jon Lester (Photo by David Banks/Getty Images), Josh Beckett (Photo by Jonathan Daniel/Getty Images) and Clay Buchholz (Photo by J. Meric/Getty Images) went a combined 6-6 with only seven quality starts in their 15 starts. The three allowed 60 earned runs in 92.1 innings pitched in the season's first month.

Hot- Mike Aviles

Mike Aviles made sure no one mentioned Jose Iglesias in April, batting .291 with five homers and 17 RBI to go with some steady defense at short. (Photo by Jim Rogash/Getty Images)

Warm- Alfredo Aceves

Aside from two really bad outings, Alfredo Aceves has filled in the closer's role nicely. Yes, he allowed eight runs in two outings without recording an out, leading to his 10.29 ERA. But he has four straight outings without allowing a run, striking out seven and notching three saves in that span. (Photo by David Banks/Getty Images)

Not- Mark Melancon

After a bad --and we mean really bad -- first two weeks, Melancon finds himself in Pawtucket to work things out. Melancon went 0-2 with a 49.50 ERA in four appearances, allowing 11 earned runs and five homers. (Photo by Elsa/Getty Images)

Hot- Ryan Sweeney

Ryan Sweeney was a big hit at the plate, and in the field, in his first month in Boston. Sweeney impressed with a .373 average in April, driving in eight and leading the team with 11 doubles. (Photo by Elsa/Getty Images)

Not- Jacoby Ellsbury

Ellsbury was off to a slow start, batting just .193 with three RBI, before injuring his right shoulder in the home opener. He is expected to be out until the end of May and possibly into June. (Photo by Elsa/Getty Images)

Warm- Cody Ross

Cody Ross only hit .257 for the month of April, but crushed five homers and drove in 18 runs, both second on the team. He also led the team with 24 strikeouts. (Photo by Jim Rogash/Getty Images)

Hot- Marlon Byrd

Marlon Byrd has thrived since coming from the Cubs, clubbing 10 hits in eight games with the Red Sox. (Photo by Jim Rogash/Getty Images)
