Peter Lambert

Lambert made the first 19 starts of his big-league career in 2019 as the Rockies cycled through rotation options, but he failed to find much success, finishing with a 7.25 ERA. Coors Field and a juiced ball may have inflated that number somewhat, but it's still not good enough in any environment, as evidenced by his park-adjusted ERA- of 144. Lambert had never been a particularly high strikeout guy in the minors, but his 13.6% strikeout rate as a rookie was quite poor. The righty has a long way to go to be an effective weapon in the majors, though at age 22 and with a decent amount of prospect pedigree, he could still get there. The Rockies' rotation looks likely to remain weak in 2020, so Lambert could be in line for more opportunities to prove his worth. Given the extent of his struggles as a rookie, though, there's not much reason for fantasy owners to invest until he starts turning the corner.
