D-Backs have only 3 positions settled as workouts begin

Posted: Updated:

SCOTTSDALE, Ariz. (AP) -- The Arizona Diamondbacks begin full-squad workouts with uncertainty at five of the eight non-pitching positions.

That's why new manager Chip Hale uses the word "competition" in about every other sentence when talking about the team.

Those who are a lock for the opening-day lineup - barring injury - are first baseman Paul Goldschmidt, center fielder A.J. Pollock and right fielder Mark Trumbo.

The rest could be any number of combinations.

The shortstops are Nick Ahmed, Chris Owings and veteran Cliff Pennington. Owings might play second, though, depending on how Aaron Hill is doing. And the outfield situation depends on whether the Diamondbacks determine that Cuban signee Yasmani Tomas can be converted to a third baseman. If he can, David Peraulta, Ender Inciarte and Cody Ross could share time in left field.
