Joe Ross: About Last Night (September 01)

I wonder if of all 32 of the pitches Joe Ross threw in that third inning, if he could take only one back would it be that 3-2 slider to Matt Carpenter? The pitch barely broke, went outside for ball four, and the Cardinals eventual first run reached base. In an inning where Ross walked four total, three straight after Jhonny Peralta singled in Carpenter, it’s funny to think that one 3-2 slider meant a scoreless inning and three runs allowed. It also meant Ross pitched his shortest outing of his young career.

I won’t get into Ross’ mental state during that third inning. He’s pitching in a pennant race with his team losing an extremely tough game the night before, and he’s on the road against the best team in the NL. He didn’t look comfortable on the mound, but then again, when not a single one of your pitches can find the strike zone, a pitcher looks that way typically. See Niese, Jon. Was it because of the liner he took off his knee in the first? Maybe it was simply being uncomfortable throwing the ball.

Most of the time I think Matt Williams leaves his starters in too long. He trusts a little too much. Last night he mercifully pulled Ross after his third straight walk, this one to Kolten Wong, and it had to be done. Ross wasn’t anywhere near the strike zone for two straight batters, and any additional suffering was sort of cruel.

The Nationals took a 4-0 lead, and it’s a shame Ross couldn’t hold the lead. The Mets mailed in their game against Philadelphia, and losing an opportunity to gain ground is one thing but actually losing ground (time is ticking away here) is another. I figure Ross was thinking about that last night too. Brandon Moss hit a dramatic walk-off home run, taking the series, and making it the second straight game Washington lost in excruciating fashion. You try to forget these games, but when they continue to happen it’s not particularly easy.

Ross, in a tough night for the rookie, threw 2 2/3 innings and allowed three earned runs on one hit and six walks while striking out three.

Below I’ve listed the particulars for yesterday’s game.

Pitches by Zone Location

##  Zone % Out of Zone % O-Swing % Z-Swing %
##   29.41         70.59     11.33     37.40

Note: Zone % is the number of pitches thrown that were considered in the strike zone; Out of Zone is the number of pitches thrown out of the strike zone; and O-Swing % and Z-Swing % relate to those pitches out of the zone and in the zone that were swung at by batters.

Calculations: I calculated the strike zone based upon the formula provided by Mike Fast in a post for Baseball Prospectus. O-Swing % = Swings at Pitches Out of the Zone / Total Pitches Out of the Zone, and Z-Swing % = Swings at Pitches In the Zone / Total Pitches In the Zone. Fangraphs has a great explanation regarding plate discipline, and I encourage you to read about it if you get a chance. After enjoying my site first, of course.

Note: Horizontal movement denotes average distance, in inches, from point of release to home plate (+ moves away from a right-handed batter) while vertical movement is average distance, in inches, from release point to home plate. As measured from the back point of home plate, the x-axis (horizontal) runs to the catcher’s right, the y-axis points at the pitcher, and the z-axis (vertical) runs upward.

Note 2: The corrected horizontal and vertical are based upon a paper by Alan M. Nathan from the University of Illinois nd account for the elimination of both gravity and drag. The corrected averages more accurately reflect the true movement of the baseball.
