Grinding Metal examines potential waiver wire additions that can assist your team during the fantasy baseball season. From home runs to pitching strikeouts, Grinding Metal has you covered. Week 12 is here, so let's start things off.
Mitch Keller, SP, Pittsburgh Pirates
Over the last four games, Keller has a 2.42 ERA and 18 strikeouts in 22.1 innings pitched. He's added an additional pitch (sinker) to his repertoire - perhaps allowing for him to go deeper into games. Two of his last three starts have been quality starts, showing glimpses of the one time big time pitching prospect. His next start comes against the Tampa Bay Rays, but his roster status should be dependent on certain matchups for streaming.
Oscar Gonzalez, OF, Cleveland Guardians
The rookie outfielder has likely been given the keys to the every day right field position going forward. Even with Franmil Reyes returning from the IL, Reyes will likely serve as the DH. On the season, Gonzalez is hitting .333/.363/.500, hitting his first two big-league home runs in his past three games. The 24-year-old rookie is owned in less than 25% of leagues.
Jon Berti, 2B/3B, Miami Marlins
He leads the NL (tied for 1st in MLB) in steals (19) and has a slash line of .279/.380/.403 and is owned in less than 35% of fantasy leagues. There isn't much more to add.
Oneil Cruz, SS, Pittsburgh Pirates
Cruz is probably already owned in your league, but if not, please go and grab him. He's a top prospect that could potentially end up hitting leadoff for the Buccos by the end of July.
Ken Giles, RP, Seattle Mariners
Giles is back in the big-leagues pitching for the first time since 2020. Has the potential to end up as the closer for the Mariners as he gains more innings pitched.
Riley Greene, OF, Detroit Tigers
Much like Spencer Torkelson, Greene is another big-time prospect for the Tigers making the big-league debut in 2022. Thus far, Greene has two multi-hit games in his first five games played. Early struggles will likely follow the success, but Greene will adjust and hit in the middle of the order for Detroit.
Jarren Duran, OF, Boston Red Sox
Duran's future as the leadoff hitter for Boston is becoming clearer, upon his promotion from Triple-A on June 15. However, with the team traveling to Toronto very soon, Duran will not be available due to his vaccination status. Overall, he's hitting .297/.366/.486 in 10 games this season. Duran could be an interesting addition, but you may have to wait until the team returns from Toronto.
