There has been little of Lopez to take in the past few seasons, in part because his 2024 ended in May due to injury and also because the Rangers’ lower affiliates just started broadcasting. Lopez did log 19 IP this last AFL season, but I wasn’t paying attention to him. This outing may have been the first time I’ve reviewed him. Lopez has produced plenty of strikeouts in his pro career, but he’s also carried the dreaded 14+BB%:

Lopez’ previous two outings this season saw him walk six, strikeout six, over six with strike%‘s in the 50s. I can’t say I know what that 22-year-old Dominican looks like, but the one I saw here impressed. Lopez went five shutout innings, allowing three seeing-eye groundball singles, walking no one, striking out 8, and throwing 71% of his 65 pitches for strikes. Even more impressive with the strike-throwing, Lopez filled up the zone with all five of his offerings: 4FB/SI/CRV/SLD/CHG. Furthermore, you’ll see Lopez earn a third strike with every offering. I can’t recall the last time I saw an arm do that. This isn’t a good angle to see his stuff work, but pairing it with the gameday plots (even if they might not be the most accurate) gives a decent look at how Lopez was working his arsenal. Lopez flashed nice three-speed sequencing. He even gave us a right-on-right changeup for a swinging K. There were a couple of close calls with long flyouts, but for the most part, this Greenville lineup couldn’t do much. I noted the putaway pitches and some slick speed changes:
Some pitch data and a better angle of Lopez would be nice, but from this glimpse, color me intrigued. This seemed like an odd “blip on the radar” outing, if that’s what it is. Typically these kinds of rookie ball strikeout and walk percentages don’t come from a guy throwing such a kitchen sink with as sophisticated attacks. Has Lopez always been pitching like this? It would maybe check out…a young guy trying higher level of difficulty attacks could produce ballooned walk rates. High walk rate guys don’t typically come across with such confidence in all their offerings like this. Regardless, I’ll be keeping on eye on what this young Ranger arm is up to this season. As The Rook and I gushed about on the podcast (episode 43,) we loved the depth of this pitching system. Developmental innings are at a premium in the mid-minors of this system, and if this look is what the Rangers were hoping they had here, I get why he’s getting them. Nothing to be running out to the waiver wires over, but if he starts stacking these outings, folks will be because the numbers will get gaudy!
