Outfield Waiver Wire for Week 22

Rusney Castillo (BOS) - 47 percent owned

As disappointing as Castillo's first stint with the Red Sox was, he's earned back the trust of fantasy owners with his performance since returning to the majors. The rookie has posted an excellent .352/.387/.568 line in his last 25 games, with four homers and 38 R+RBI. Just two steals in three attempts, though when a guy's bat is this hot, he doesn't need to run to provide value. Not much has gone right in Beantown this season, but Castillo's given Sox fans a reason to dream in 2016.

Khris Davis (MIL) - 41 percent

Davis is too strikeout-prone to be anything but a liability in batting average and OBP, but his nickname is Khrush for a reason. He has more than earned that moniker in August, with 10 homers in just 89 at-bats. All those long balls have helped him lead the Brewers with 40 R+RBI and a .596 slugging percent over the last month. Davis is as streaky as they come, so a caveat emptor might be in order here. At this point in the season, though, you're not going to find too many players on the wire hitting bombs at the rate he's been doing it lately.

Jackie Bradley Jr. (BOS) - 32 percent

We all remember JBJ's coming out party two weeks ago against Felix Hernandez and the Mariners. Fortunately for owners who took the bait, he's continued to hit since then, posting a healthy .278/.350/.611 line with two homers and two stolen bases. He isn't playing every day, so we're dealing with an even smaller sample than two weeks would normally provide. But the longer he keeps this up, the more plausible it becomes that the lightbulb has gone on for the former top prospect.

Franklin Gutierrez (SEA) - 11 percent

Gutierrez played just 173 games in the four seasons prior to this one, and he was hardly a fantasy stud before all that missed time. But man, is he hitting the ever-loving crap out of the ball right now. A .333/.382/.746 line with seven homers and 20 RBI in only 63 at-bats over the last month? Sign me up. The Mariners veteran has 20 homers in just 258 AB over the last two seasons and is a sneaky source of power for owners in deeper leagues. Even in shallow formats, he's worth adding while this hot streak keeps chugging along.

Michael Conforto (NYM) - 5 percent

A 22 year old posting an .849 OPS at the major league level ought to be garnering a bit more attention, both in real life and in fantasy. This being the year of the rookie, though, Conforto has gotten surprisingly little love. Yoenis Cespedes has gotten a lot of credit for the Mets' recent dominance - as he should - but Conforto shouldn't be free to add in 95 percent of Yahoo leagues. He's scored 20 runs and knocked in 13 in his 27 games to go along with three homers, so you're getting solid contributions across the board.
