Throughout baseball history, the month of April often features slow starts not indicative of how a player will perform over the course of the season – but sometimes, it can foreshadow breakout seasons for relative unknowns, or the downfall of transcendent stars. After one month in 2015, there have been nothing short of storylines worth following. While many of the faces of MLB haven’t performed up to their career norms, teams have seen their fair share of dominant performances from other contributors. Here are the top performers at each position after one month of action.

Catcher: Salvador Perez

Over the past three seasons, Sal Perez has established himself as one of the premiere catchers in a league devoid of productive backstops. With the rare combination of defensive prowess and the ability to hit for contact and power, Perez has provided the Royals with a steady presence behind the plate, and in the middle of their lineup.

In 2015, Perez has only continued to improve by boasting an impressive .326/.337/.474 slash line. His impact at the dish is catching up to his wizardry behind the plate. Dominant starts from Stephen Vogt and Derek Norris garnered consideration here, but Perez has proven to be a reliable option. Expect Perez to establish himself as the gold-standard behind the plate for the rest of this season, and his entire career.

First Base: Adrian Gonzalez

After smashing five home runs in the Dodgers’ first three games, Adrian Gonzalez’ hot start has yet to tally off. With a significant dropoff in the power department since his dominant 2009 season, Gonzalez has become a feared contact hitter with inconsistent pop. That narrative has changed this season.

Through 101 plate appearances, Gonzalez has a 1.152 OPS – along with a ridiculous .723 slugging percentage. Gonzalez isn’t the only first baseman with a hot start in 2015 – currently, 12 first basemen, including Gonzalez, are hitting over .300. What separates A-Gon is his knack for getting on base, and extreme turnaround in the power department. Look for Gonzalez to keep up his torrid pace and carry the Dodgers the rest of the season.

Second Base: Jose Altuve

Jose Altuve is known around the league for his high hit counts and game-changing speed. However, in the past few seasons, Altuve and the Astros couldn’t translate that talent into wins. This season is different in Houston; currently sporting an 18-7 record, they’ve beaten the likes of Los Angeles and Seattle for the top of the AL West – due in large part to Altuve.

As it stands now, Altuve is slashing .360/.410/.514 with a whopping 40 hits – good for second in the league behind Dee Gordon. Speaking of Dee Gordon, he and Rockies second baseman D.J. LaMahieu are having fantastic seasons in their own right, but it’s the Astros record that separates Altuve. Altuve should have no problem surpassing the 200 hit mark again this season, and maybe, just maybe, a few of them will come in the postseason.

Third Base: Matt Carpenter

Widely regarded as one of the deepest positions in baseball, third base has had no shortage of dominant performances in 2015. While several players have played well in 2015, Matt Carpenter has been nothing short of excellent. After a disappointing follow-up to his breakout 2013 (.319 AVG) in which he hit .272, Carpenter’s expectations were tempered coming into 2015.

So far, Carpenter has been the rock atop the Cardinals order that they so desperately needed. Currently owner of a 1.036 OPS, Carpenter looks poised to maintain his dominance the rest of the season. Boston’s new $95 million dollar man Pablo Sandoval was also considered, but with his dismal numbers from the right side of the plate, Carpenter has the edge.

Shortstop: Jose Iglesias

If anyone correctly predicted that through one month, 11 shortstops would be hitting over .250, they’d instantly be hired as the new commissioner. Realistically, who expected Jose Iglesias and Freddy Galvis to have the top two batting averages among all shorstops? So far, Iglesias has silenced his doubters after missing the 2014 season without much of a track record at the plate to warrant a starting job.

Up to this point, Iglesias is hitting over .350 through 86 at-bats. Although his .386 BABIP isn’t sustainable, Iglesias has proven he has the tools to hit consistently, at least for a month, at the Major League level. Even if Iglesias’ bat cools down, his defense warrants consideration for the “Best Shortstop in the Game” conversation. It’ll be interesting to see what Iglesias does from this point forward, but so far the Tigers are looking awfully smart for not acquiring another shortstop this offseason.

Left Field: Hanley Ramirez

Could the Red Sox have asked for more from Hanley Ramirez? Right now, the $88 million dollar deal they signed him to this offseason is proving to be a steal as the slugger has clubbed 10 home runs to go along with a .283 average. With concerns over his health in the past few seasons, many teams strayed away from making a run at the former shortstop, but Han-Ram possesses legitimate power perfectly fit for Fenway Park.

To go along with his .283 average, Ramirez is slugging .609 with an On-Base Percentage of .340. While his transition to left field hasn’t been exactly smooth, his hitting will make up for any issues out near the Green Monster. Michael Brantley is having a terrific start to the season with a .352 average, but his back strain has limited his power in the early going – keeping him from claiming the crown atop left field.

It looks as if he’s already getting acquainted with his outfield partner.

Center Field: Adam Jones

Talking about Adam Jones’ torrid start seems repetitive at this point, but it’s necessary given the center fielder is batting .402 while getting on base at a .438 clip and .667 (!) slugging percentage. Jones has been one of the most consistent hitters over the course of his career, but a start like this is eye-opening for anyone.

After losing several key pieces this offseason, the Orioles offense seemed due to regress – but Jones hasn’t let that happen. Several other center fielders have dominated to start 2015, including the likes of reigning AL MVP Mike Trout and Angel Pagan, to name a couple, but none have played quite as well as Jones. Expect Jones to regress a bit, but in a competitive AL East – he’ll be playing his best to push the Orioles into the playoffs.

Right Field: Josh Reddick

Seemingly out of nowhere, Josh Reddick has once again established himself as a productive hitter for the Oakland Athletics. Many have forgotten about his 2012 season in which he slugged 32 home runs – due in large part to injuries suffered in 2013 and 2014. Reddick is out to prove his pop is legit, and is having no trouble thus far in 2015.

Through 69 at-bats, Reddick is hitting .389 with a 1.102 OPS – oh, he also has 20 RBI. To say Reddick has been impressive for the new-look A’s would be an understatement. Coupled with his defensive abilities in right field, Reddick has the makeup of a star for Oakland – and is out to prove his hot start hasn’t just been a fluke.

Utility: Brock Holt

Brock Holt’s outstanding 2014 season for the Boston Red Sox was seemingly out of nowhere, but has vaulted him into the conversation among the best utility-men in the game. Holt is out to prove utility players can have an everyday impact in the field, and in the batter’s box. Through 49 at-bats in 2015, the Brock Star is slashing .358/.433/.509 – helping keep the Red Sox afloat in the wide-open AL East.

Starting Pitchers: Dallas Keuchel

Starting pitcher is probably the toughest position to pick a best player given its depth and lack of consistency. However, Astros’ ace Dallas Keuchel has continued his rise to the top of the ranks among starters since his breakout last season. After posting a 2.93 ERA in 2014, Keuchel was pegged as a rising star – but no one could have predicted his absolutely dominant start to 2015.

Through six starts (45 IP), Keuchel has a 0.80 ERA while having only allowed 4 (!!) runs. With a 2.67 FIP (Fielding Independent Pitching), Keuchel has proven he isn’t a fluke. While Sonny Gray, Chris Archer, Felix Hernandez, and countless others have dominated to start the season, none have been as good as Keuchel. The Oklahoma native has pushed the Astros into contention in the loaded AL West, and if he keeps it up – the Astros could see the playoffs much earlier than expected.

Relief Pitcher: Wade Davis

After Royals’ closer Greg Holland landed on the disabled list a few weeks ago, setup man Wade Davis was called upon to handle closing duties. In his time as closer, Davis has simply recorded five saves without giving up an earned run. Expect Davis to continue his dominance in the setup role once Holland returns.

In a list without Mike Trout, Andrew McCutchen, and Clayton Kershaw, MLB has been lucky to have several players step up to assert their dominance over the league. As offense continues to return to prominence in 2015, expect players – and pitchers – to step up to another level.
