As injuries plague MLB rosters early in the season, fantasy managers face tough waiver wire choices. Geraldo Perdomo of the Arizona Diamondbacks has emerged with a hot start, boasting a .333 average and some power, but his historical performance suggests caution. Zac Veen, called up by the Rockies, showcases enticing speed yet struggles with a high strikeout rate, making him a risky add. Meanwhile, Mitch Keller of the Pirates delivered a stellar outing but maintains a mediocre ERA, hinting at inconsistency. Managers must weigh the potential against the pitfalls when navigating these popular players on the waiver wire.
