Robertson is out of the lineup Monday against the Royals. Robertson has picked up the bulk of the starts in left field over the last 10 days, and has done well in accruing a .303 average and .374 on-base percentage in 132 at-bats. However, Robertson has very limited power and in making his MLB debut this season at 28 years old, he'll have little chance of opening 2015 as a starting outfielder for the team.
