Rock

The move to add Rock to Tampa Bay’s 40-man roster ahead of this week’s reserve list deadline guards him from selection in next month’s Rule 5 Draft. The 24-year-old lefty, who was acquired back in March from the Rockies in a small trade, posted a pedestrian 4.58 ERA, 1.40 WHIP and 132/35 K/BB ratio across 139 2/3 innings (27 appearances, 23 starts) last season for Triple-A Durham.

Rock pitched just two innings of spring ball with the Rockies and allowed three earned runs on four hits. The 23-year-old southpaw made 19 starts at the Double-A level last season where he posted a 5.30 ERA with a 108/32 K/BB ratio across 90 innings.

Rock, 21, allowed one hit, and issued a pair of walks. The left-hander lowered his ERA to 3.75 over 50 1/3 innings in the Northwest League, and improves his K/BB ratio to 55/20 in his nine appearances. The 68th pick of the draft out of Ohio, Rock has two potential plus pitches in his fastball and slider, and he also has a change that has made progress. He profiles as a backend starter at this point -- and Colorado isn’t the greatest place to pitch, as managers are aware -- but the 6-foot-6 southpaw has a chance for fantasy relevance if he sees a tick up in stuff.
