Donaldson has been a monster in the last seven days, belting three homers and driving in nine runs. After a slow start to the season, he's hitting .279/.338/.533 with seven homers and 23 RBI and has generally been one of the top performing fantasy third basemen.
Much of the spotlight is shined on Yasiel Puig, Hanley Ramirez, Matt Kemp and the starting rotation, but Gonzalez just finished off a scorching April. He punctuated it by hitting three homers, driving in seven runs and posting a .478 OBP in the last week. He's now hitting .317/.377/.644 with eight homers and 24 RBI for the season.
The Braves pitching staff is largely responsible for the team's 17-9 record in April, but Upton carried the offense through the month. He had three homers, six RBI, one steal and a .500 OBP in the last seven days.
Wilson has quietly been one of the most effective pitchers in the majors thus far this season, a pattern that continued last week. He won both of his outings, striking out 13 batters and allowing just two runs and six hits in 14 innings. He's 4-2 with a 3.18 ERA, 3.43 FIP and 41 strikeouts in 39 2/3 innings this year.
Through one month of his rookie season, Abreu sure seems worth the investment for the White Sox. He had three homers and 11 RBI last week, including a walkoff grand slam in a win over the Rays on Friday, providing one of the better bits of theater in the young 2014 season.
Seager got off to a miserable start this season, but he ended April with a bang, hitting three homers with six RBI, four runs scored, one steal and a .471 OBP. His slash line still doesn't look great, put his OPS is now pushing .800.
Saltalamacchia remains widely available at a shallow position, but that could start to change after the week he just had. The Marlins backstop put up a .524 OBP with three homers, four RBI and six runs scored. He's a worthy addition for those of you in mixed leagues struggling at catcher.
Castro's bounceback 2014 continued in the last week, when he went 9-for-23 with two homers, five RBI, one steal, four runs and a .440 OBP. It's safe to say his dreadful 2013 campaign is comfortably in his rear-view mirror.
A healthy Tulo is a dominant Tulo, and we saw why for the entire month of April. He had three homers, six RBI and a .423 OBP last week, helping the Rockies take four of six from the Dodgers and Diamondbacks.
Hudson was dominant in wins over the Indians and Padres last week. He held the Indians to one run on four hits in seven innings, then just barely missed a complete game against the Padres, tossing 8 2/3 innings and allowing two runs on five hits.
Aybar isn't likely to make this list all that often, but he had a big week, going 10-for-25 with a homer, six RBI and eight runs. The relative lack of depth at the shortstop position makes him somewhat relevant in deeper leagues, but don't expect too many weeks like this.
Ventura's first outing last week was a gem, as he fanned eight Orioles and didn't surrender a run while scattering seven hits and two walks in eight innings. He labored in his second start, though he ended up throwing five shutout innings against the Blue Jays. He left in line for the win, but the bullpen gave it up.
Roark threw his first career complete game last week, shutting out the Padres while striking out eight and allowing just four baserunners. He'll remain in the Washington rotation as the fifth starter when Doug Fister returns from the DL.
The one and only Trout makes the power rankings again after going 7-for-20 with a homer, four RBI, two steals and a .500 OBP last week. On the downside, he has fanned 34 times in 124 plate appearances this season.
Another one and only, Fernandez is back in the power rankings after dominating the Braves last week. He threw eight shutout innings, allowing just four baserunners and striking out eight to move to 4-1. He has 55 strikeouts and just eight walks on the season.
The Gomez show continued last week, when he went 8-for-26 with two homers, three RBI, five runs, a steal and a .379 OBP. Gomez has matured into one of the best all-around players in the majors, which seemed impossible a few short seasons ago.
Our first closer in the power rankings, Rodriguez earned the distinction after going 4-for-4 on save opportunities last week. He struck out five batters, didn't all a run, and let just three men reach base.
Scherzer beat the White Sox twice last week. He went six innings in each start, striking out 10 and allowing two runs on seven hits in the first, then fanning seven while surrendering zero runs and four hits in the second. He's 3-1 with a 2.08 ERA, 2.70 FIP and 51 strikeouts in 39 innings this year.
Burnett was masterful in his one start last week, though it was against the lowly Diamondbacks. He threw eight shutout innings, striking out eight and allowing five hits without a walk. Given that the walks have plagued him this year, it was an encouraging development.
Wainwright owned yet another foe last week, going eight scoreless innings against the Pirates, striking out seven while giving up three hits and two walks. He needed just 99 pitches to get through his eight innings, and is now 5-1 with a 1.20 ERA and 0.78 WHIP this season.
Kennedy had his best outing of the season last week, allowing just one run and three hits in seven innings, striking out nine in a win over the Nationals. It was his first win in exactly three weeks, and moved him to 2-3 with a 3.16 ERA and 2.56 FIP on the season.
Teixeira had just three hits last week, but he made all of them count. Each one sailed over the fences, though they were all just solo shots. He also drew plenty of walks, posting a .500 OBP for the week. Still, he's not a guy you want to own unless you're in a very deep league.
