Ortiz may have only played in nine games this April, but he made the most of each of them. Ortiz has at least one hit in every game, going 18-for-36 since finally returning from his lingering Achilles injury for a .500 batting average, while clubbing three home runs and driving in 15 runs. Ortiz is slugging .917 in his small sample, providing the Sox with a big bat in the middle of the order. (Photo by Jim Rogash/Getty Images)

HOT - Jon Lester
Lester led the way for the Red Sox success in April (minus his final outing), going 4-0 in six starts with a 3.11 ERA and holding batters to just a .220 batting average. (Photo by Jared Wickerham/Getty Images)
HOT - Clay Buchholz
As good as Lester has been, Buchholz has been even better. Buchholz became baseball’s first five-game winner with a 7-2 victory over the Astros, making him a perfect 5-0 with five quality starts this season. He’s allowed just five earned runs over 37.2 innings of work for a 1.19 ERA, and is second on the team with 39 strikeouts. (Photo by Jim Rogash/Getty Images)
NOT - Alfredo Aceves
Aceves allowed 17 earned runs in 17.2 innings this season, splitting time between the bullpen and starting rotation, before being sent to Pawtucket in the final week of the month. In his final start, a 13-0 loss to Oakland, Aceves allowed seven earned runs over 3.1 innings, walking four, balking twice and making a defensive blunder as well. (Photo by Jim Rogash/Getty Images)
HOT - Mike Napoli
Napoli is off to a hot start to begin his Red Sox career, with 18 of his 28 hits going for extra bases. He leads the team with 27 RBIs in his first 26 games in Boston. One concern for Napoli though is his team-leading 40 K's at the plate. (Photo by Jim Rogash/Getty Images)
NOT - Will Middlebrooks
He has turned it on as April came to a close, but it was a frustrating start of the season for Will Middlebrooks. For the month, he is hitting just .194 with 32 strikeouts in 94 at-bats. Six of his 19 hits have come in the last week of the month, so it looks like he is turning his slump around heading into May. (Photo by Jared Wickerham/Getty Images)
HOT - Andrew Bailey
With Joel Hanrahan on the shelf with a hamstring injury, Bailey stepped into the closers role that he was never able to claim last season. Bailey has been one of Boston’s best relievers early on, notching five saves and four holds in 13 appearances, striking out an astounding 20 batters while allowing just two earned runs over 12.1 innings pitched.

NOT - Joel Hanrahan
After a shaky spring and looking less-than-dominant in three of his first six appearances, Hanrahan landed on the DL with a hamstring injury. He returned to the pen (not as the closer) on the final day of the month and allowed a run in an inning of work. (Photo by Jim Rogash/Getty Images)
HOT - Daniel Nava
While a lot of the early-season talk surrounded Jackie Bradley Jr., Daniel Nava quietly made his way onto the team. When given the opportunity to play, Nava has made the most of it. He is second on the team with four home runs and 16 RBIs, including a clutch, go-ahead three-run blast against the Kansas City Royals in the eighth inning of a 4-3 win.
