Weaver's fastball topped out at 83 mph while he struck out three and gave up no hits in two innings Friday, Alden Gonzalez of MLB.com reports.

Weaver lost a couple ticks off what was already a very slow fastball in 2015 and went on to have a pretty rough season, putting up a 4.64 ERA and 5.09 K/9 in 159 innings. He performed well enough Friday against the Cubs, but if his velocity doesn't get better throughout camp, he'll be entering the regular season with a bag of tools that barely worked last season.
