Carson Kelly has gotten the most playing time this spring and has gone 5-for-19 with three doubles.

A new battle has opened up in Arizona following the signing of Adam Jones. Jones isn't the player he once was, but his .281/.313/.419 line last season was still good for a roughly average 98 wRC+. That's not a great number for a corner outfielder but is perfectly playable in center, though the 33-year-old's glove has graded out quite poorly in recent years. The Diamondbacks had been planning on shifting Ketel Marte to center field, though Jones' arrival could shift him into a super utility role, potentially to the detriment of middle infielders Wilmer Flores and Nick Ahmed. Jones probably fits better in right field, where he'd be in a direct competition with Steven Souza, who struggled to a .220/.309/.369 line in an injury-riddled season last year.

Merrill Kelly had a rough start to the spring, allowing five earned runs on five hits with
