Finally healthy, Jay Groome is showing what he can do.
The Red Sox's No. 2 prospect (No. 35 overall) fired five hitless frames with six strikeouts and two walks on Thursday as Class A Short Season Lowell defeated Hudson Valley, 5-2.
It was Groome's third rehab appearance in the New York-Penn League since returning from a two-month stint on the disabled list for a lat strain, which he suffered during his season debut with Class A Greenville. The 18-year-old lefty surrendered one earned run in each of his first two turns while completing 2 1/3 and 3 2/3 innings, respectively, before stretching out his pitch count to 85 (49 strikes) on Thursday.
Groome, the 12th-overall Draft pick in 2016, made just three starts last summer, posting a 2.70 ERA with 10 strikeouts in 6 2/3 innings across two levels, after signing for $3.65 million -- a franchise record for a drafted pitcher.
The rest of the best performances from top prospects Thursday
• No. 37 overall prospectReynaldo Lopez (White Sox No. 5) set a season high with 11 strikeouts as he tossed 6 2/3 frames of one-run ball to lead Triple-A Charlotte past Columbus. The 23-year-old right-hander has fanned 79 batters in 81 innings this season while posting a 4.22 ERA in 15 starts.

Rhys Hoskins (No. 13) also homered for the IronPigs for the second time in as many games. He leads the International League with 19 home runs.
