'Improved' Juan Minaya adds split-fingered fastball to repertoire

The White Sox wanted Juan Minaya to add another pitch when he casually mentioned a few weeks back he throws a split-fingered fastball.

The hope is to another pitch could help the rookie reliever improve against left-handed hitters. Minaya -- who has converted seven of eight saves with 49 strikeouts and a 4.75 ERA in 41 2/3 innings -- threw a split-finger fastball when he pitched in the Houston Astros farm system. But Minaya said the Astros thought he threw it too hard and discouraged its use. The White Sox are more than happy to have Minaya be able to attack another quadrant.

“The (changeup/split-fingered fastball) has been a nice addition,” pitching coach Don Cooper said. “We’re also trying to get him better and more consistent with his breaking stuff.

“Minaya has probably been one of the most improved guys, from the moment we picked him up from Houston, getting his delivery better. He’s throwing more strikes than he ever has with all of his pitches and the delivery enables that.”

Minaya, 27, hasn’t been scored upon in his last five appearances, though Avisail Garcia bailed him out with an assist on a wild game-ending play on Friday night.

Part of that success has come from the addition of the split-fingered fastball, which Minaya has thrown 16 times this month. Before September, Minaya had thrown the pitch only 11 times at the big-league level.

Minaya already throws a four-seam fastball, curve and a slider. But the split gives him a secondary pitch for lefties, who have an .829 OPS against Minaya this season.

“You can see he has confidence in it because he’s shaking to it a lot, which I love,” said catcher Kevan Smith. “He needed to throw that off his fastball. He has more than above average breaking stuff, but he broke it out a few weeks ago and we were like, ‘You’ve been holding out on us all season with that.’ That’s just going to bring more value to him, make more effective. A little more confident and successful.”

With the team’s entire original bullpen cast either traded or injured, Minaya has temporarily been thrust into the closer’s role. The mild-mannered righty has handled the ninth as well as could be expected and has shown the White Sox he has the stuff to potentially help out in the bullpen moving forward. Minaya would like to improve his fastball command but is pleased with how he’s handled a tricky situation. He’s also glad to have the White Sox supporting him throwing the split-fingered fastball.

“The other day I was talking with Coop and he said you need to get another pitch for lefties,” Minaya said. “I said I can throw the split, but I throw it hard. He said OK and I started throwing.

“The ninth inning is a tough inning, but you have to go out and compete.”
