4 ARIZONA DIAMONDBACKS

O/U WINS: 75.5

KEY PLAYER: RHP Zac

Gallen looked good in a limited sample size in 2019 and then backed it up last season with a 2.75 ERA. The emerging ace just needs to get healthy after sustaining a hairline stress fracture in his forearm late in camp. PLAYER WHO’LL NEED TO STEP UP: The first year of Eduardo Escobar’s three-year,

$21 million pact with the D’backs was a success

(3.6 WAR). The second was a bust (-0.5 WAR). They’ll need the 2019 version of Escobar to have a shot. NAME YOU’LL GET TO KNOW: Pavin Smith has a chance to play a bigger role in the outfield after a solid debut last season. The 2017 firstround pick hit .270 with a .746 OPS in 12 games in 2020.

BIGGEST QUESTION MARK: How much does

Madison Bumgarner have left in the tank? After signing a five-year, $85 million contract, the lefty began his Diamondbacks tenure with a fizzle, posting a 6.48 ERA in nine starts last season. If he can at least get closer to what he was with the Giants, it’ll go a long way in solidifying Arizona’s staff.

HOW IT’LL GO DOWN: Trading away Paul Goldschmidt and Zack Greinke seems to have caught up with the Diamondbacks, with the returns not yet paying dividends — though it figures to be important years in the development for some of the pieces they got back, like catcher Carson Kelly, pitcher Luke Weaver and perhaps even pitching prospect J.B. Bukauskas.
