Lamb's second season as an everyday player for the D-backs looks nearly identical to his first one -- he continued to mash against right-handed pitching (.282/.386/.552, 133 wRC+, 20.5 percent K%) only to struggle against lefties (.144/.269/.288, 44 wRC+, 34.6 percent K%). To his credit, Lamb has shown the ability to walk against lefties in each of the last two seasons, and his overall walk rate peaked at 13.7 percent in 2017. As was the case in 2016, Lamb's first-half production (.922 OPS) was significantly better than his second half (.735 OPS), but there is no clear cause behind that trend to this point. Entering his age-27 season, it will be interesting to see if he's given a third year of regular exposure to southpaws, but a strong supporting cast will go a long way toward stabilizing his value even if his overall volume of playing time takes a hit and the new humidor in Chase Field saps his power some.
