Melendez struggled through three seasons in the Dominican Summer League before Houston gave up on him.  The White Sox picked him up and he improved substantially, although he was old for the level by then.  In those days, he was running his fastball up to 96, but didn’t hold his velocity well.  In 2021, he was throwing in the upper-90s, touching 100.  His out pitch is a curve and he also throws a change.  San Diego selected him in the minor league phase of the 2018 Rule 5 draft.  The Padres immediately sent him to the Pirates for cash in a deal that no doubt was worked out in advance.

DSL:  2-4-0, 2.78 ERA, 1.50 WHIP, 22.2 IP, 5.6 BB/9, 7.5 K/9

Melendez pitched in short relief in his debut.  He didn’t pitch as well as the ERA implies, as shown by his walk and K rates.  He didn’t get hit hard, but opponents had a .382 OBP against him.

DSL:  4-2-2, 3.86 ERA, 1.49 WHIP, 35.0 IP, 4.6 BB/9, 9.0 K/9

Back in the DSL and still pitching in relief, Melendez had a somewhat similar season, although his K rate was good.

DSL:  0-3-3, 7.68 ERA, 1.76 WHIP, 36.1 IP, 6.7 BB/9, 7.9 K/9

In his third try at the DSL, Melendez went backwards.  His walk and K rates regressed, and opponents got on base at a .407 clip.  Houston released him after the season.

DSL:  4-4-0, 1.54 ERA, 0.95 WHIP, 70.1 IP, 3.6 BB/9, 11.9 K/9

The White Sox signed Melendez at the end of spring training and sent him back to the DSL for his fourth try.  Pitching mostly as a starter, he made dramatic progress, with a very high K rate and an opponents’ OPS of just .454.

A:  2-3-1, 5.13 ERA, 1.29 WHIP, 47.1 IP, 4.9 BB/9, 14.5 K/9

Melendez joined Greensboro out of extended spring training in mid-May and spent the season there.  He had an interesting year, with an outstanding K rate.  He had control problems but not drastic ones and opponents only hit 203/327/314 against him.  Somehow though — partly due to a very low strand rate of 62.5% — he had a bad ERA.  His xFIP of 3.18 was very good.  He had a big home/road split, with a .739 opponents’ OPS at home and .564 on the road, so the high-offense park at Greensboro may have inflated his overall numbers.  He had a moderate platoon split, with right-handed hitters putting up a .611 OPS and left-handed hitters .706, with the difference mainly resulting from a very high walk rate against the latter.


Apart from payroll-slashing, one of the Pirates’ bigger focuses in the 2018-19 off-season was adding lower level pitching depth.  The addition of Melendez seems to have worked out, if the big K rate holds.  They’ll have to decide whether to protect him from the Rule 5 draft, as the K rate could tempt somebody.
