Tolleson (back) is having his workload closely monitored due to past back problems, Marc Topkin of the Tampa Bay Times reports.

EDGE Analysis

Tolleson is currently able to throw without issue, but is not yet being asked to participate in any defensive drills so as to not get overworked early. The veteran righty is looking to bounce back after the worst season of his career in 2016, a campaign during which he went 2-2 with a 7.68 ERA and 1.73 WHIP over 36.3 innings.
