22-year-old LHP David Peterson has been dominant with Low-A Columbia, allowing just one earned run over his last 19.0 innings (three starts).
Peterson, the Mets' top pitching prospect, allowed one run on two hits in 7.0 innings on Monday while walking three and striking out four. He tossed 7.0 scoreless innings while allowing three hits, walking none, and striking out eight during his start on May 7.
Overall, Peterson has a 2.05 ERA and 1.08 WHIP with 25 strikeouts in 30.2 innings (five starts) this season.
Peterson, who the Mets selected with their first round pick (20th overall) in last June's MLB Draft, is No. 58 on Keith Law of ESPN's Top 100 Prospects list.
Calling Peterson "more of a command lefty than the power guy you might expect from his frame," Law wrote the following:
"Peterson's fastball comes in at 90-92 on average and touches 94 when he needs a little more, but the grade 55 slider is his out pitch, and he can throw both for strikes. He takes advantage of his height with huge extension toward the plate and has a little funk in the back of his delivery to give him some more deception."
Law, who added that Peterson will need to throw his changeup more in pro ball in order to stay ahead of right-handed hitters, said he should "sail through A-ball given his ability to throw two pitches where he wants them and the difficulty hitters have seeing the ball."
"He has a high floor as a back-end starter," Law concluded, "but there's a little Chris Sale/Alex Wood potential here if he adds velocity when he fills out."
