3 straight good outings for Jonathan Cannon

Jonathan Cannon received his first opportunity to pitch in the big leagues in April. It did not go well.

The 23-year-old right-hander made three starts for the White Sox during his initial recall, going 0-1 with a 7.24 ERA. He allowed 11 runs on 20 hits over 13.2 innings pitched.

He was sent back to Triple-A Charlotte, where he made a couple of changes to his grip on his sinker and changeup. The result has been more velocity on his sinker, and more downward action on his change.

Since being recalled to Chicago earlier this month, Cannon has had three straight good outings.

He earned his first career save June 7 against Boston, when he tossed three shutout innings with four strikeouts in a 7-2 win over the Red Sox.

Cannon returned to the starting rotation June 12 at Seattle. He threw seven innings of one-run ball, allowing only four hits -- including a solo home run in the seventh -- with seven strikeouts and one walk. That resulted in a no-decision as the Sox lost, 2-1, in 10 innings.

Then came Tuesday, when the former third-round draft pick fired 8.2 shutout innings against the Houston Astros. He allowed seven hits, but only one walk, with four strikeouts. Seventy of his 106 pitches were for strikes, and he picked up his first career win as the Sox prevailed, 2-0.

This game very easily could have been a complete-game shutout. Cannon retired the first two batters he faced in the top of the ninth inning, and he was one out away from finishing it off. Alas, a check-swing single by Jon Singleton and a ground ball with eyes off the bat of Mauricio Dubon put the tying runs on base for Houston with two outs.

At that point, Sox manager Pedro Grifol made a pitching change, with a chorus of boos cascading down upon him. Grifol has been rightfully criticized for many things, but this was the correct move. You don't let Cannon lose the game after how well he pitched, and John Brebbia is paid $5 million per season to get outs in relief.

Indeed, Brebbia retired Victor Caratini on a routine grounder to first base to earn his second save of the season.

Now, it's worth noting that Cannon faced a compromised Houston lineup that was missing its two biggest left-handed bats: Yordan Alvarez (personal reasons) and Kyle Tucker (leg contusion). It's also worth noting that it's only three outings, and all the usual caveats about small sample sizes apply.

But, Cannon is the first Sox pitching prospect to do much of anything with an opportunity so far in this lackluster season. Since his recall, he has an 0.52 ERA, and his season ERA is down to a respectable 3.34.

Is it possible that the changes he's made to his sinker and changeup will make him a viable big-league starter? Or is this just a hot streak from a fringe player?

At least it's something to monitor and talk about with the Sox (20-54) hopelessly buried in the standings.
